using color lcd displays brands

OLED displays (Organic Light-Emitting Diodes) are a newer display technology than TFTs, but are becoming more popular than TFTs. They are used in new cell phones, digital cameras, and medical equipment. OLEDs are an excellent fit for any product that needs multi-color, a thin profile, and low power (battery powered.)

TFT’s Displays (Thin Film Transistor) are full color modules that can display graphics, characters and video. TFTs are great for adding an interesting user interface to any product. They are used in older cell phones, tablets, laptops and digital photo frames.

FSC LCD (Field Sequential Displays) displays were a popular technology a few years ago, but have since fallen out of favor due to several factors, the main concerning being the operating temperature, limiting it for many outdoor environments with colder temperatures.

FSCs are a segment display with the ability to change each segment to any of seven colors vs. older segment displays that were only one color. FSC displays are custom and require a one-time-tooling fee to be paid. There is also a MOQ of 1K

If you need multiple colors than we recommend OLEDs or TFTs. If you only need two or three colors we recommend a UWVD LCD (Ultra-Wide Viewing Display Technology) display with silk-screening. UWVD display technology is available in both segmented and character displays. UWVD fluid is rotated perpendicular to the LCD glass and provides a wider viewing angle and brighter backlight.

Automation in industries has picked up pace over the last few years. When it comes to automating systems and processes, we need a display that will show us the required output in the format we understand. Hence, displays are an important part of any electronic system simply because we cannot decode the binary language on our own. However, gone are the days when there were black and white monitors and display screens. Now, LCD displays are being used in their place. The LCD display manufacturers have come up with several types of displays that go beyond just displaying data. You can easily upgrade your old display modules and opt for custom LCD displays that suit your application. This post discusses various types of color graphic LCD display modules and the reasons why you should upgrade to a color display.

TFT LCD Display: The thin film transistor (TFT) LCD can display up to 16 million colors, and with amazing accuracy and picture quality. It is cost effective and has anti-glare features. These LCD displays can be customized in different resolutions, dimensions, as well as technologies to meet diverse application requirements.

Touch Panel Displays: This is a durable and waterproof display. You can wear your gloves and use it, and hence is useful in medical applications. The capacitive and resistive touch panels in these displays create an interactive experience for the users.

Monochrome LCD Displays: Monochrome graphic LCD display modules present data in text (alphanumeric), symbols, and graphics. These are very common in industrial and retail applications, and offer an easy-to-read format in a cost effective manner. You can fit them anywhere because of the small form factor.

In this age of IoT and everything “smart”, opting for custom LCD display modules is quintessential. Although industries and businesses would benefit the most by upgrading displays and overall systems, there are other areas which need this switch as well. These include display screens on roads, healthcare facilities, train stations, bus stations, educational institutions, and even our homes. Here are some reasons why switching to color LCD displays may be a useful proposition:

Obsolete systems: With so many new devices coming in, the older ones become obsolete very fast, and you do not find them in the market at all in case of repair or replacement of screens or whichever parts. So, a technological overhaul along with high-resolution graphic LCD display module is the best solution. Also, most of these new devices can be easily upgraded with newer versions after a few years, and you need not replace them.

Limited Memory: Some microcontrollers have very less on-chip RAM and hence are not be able to produce the kind of color depth and resolution display screens have nowadays.

Enhanced Features: Old display screens do not have touch control and zooming options which are there in new LCD displays. It’s far easier to read from LCD screens, wherein you can easily zoom in and out. Also, other features such as enhanced clarity and a well-developed graphical user interface (GUI) add a lot of value.

Color Gamut: The standard RGB color gamut devised by IEC in 1998 is used in most products with LCD displays. There are other color gamut standards devised by Adobe and NTSC as well. However, LCDs reproduce this color gamut far more accurately than their older counterparts.

If you are looking to overhaul the electronic system in your manufacturing unit or application, make sure you opt for high resolution LCD displays when it comes to changing your screens. However, it is essential that you choose it from a reliable manufacturer such as Microtips USA. The company has an experience and expertise in equipping modern machineries in various manufacturing plants across the Americas, Europe, and Asia. They are focused on quality and are ISO9001 and ISO14001 certified.

Get rich colors, detailed images, and bright graphics from an LCD with a TFT screen. Our standard Displaytech TFT screens start at 1” through 7” in diagonal size and have a variety of display resolutions to select from. Displaytech TFT displays meet the needs for products within industrial, medical, and consumer applications.

TFT displays are LCD modules with thin-film transistor technology. The TFT display technology offers full color RGB showcasing a range of colors and hues. These liquid crystal display panels are available with touchscreen capabilities, wide viewing angles, and bright luminance for high contrast.

Our TFT displays have LVDS, RGB, SPI, and MCU interfaces. All Displaytech TFT LCD modules include an LED backlight, FPC, driver ICs, and the LCD panel.

We offer resistive and capacitive touch screens for our 2.8” and larger TFT modules. Our TFT panels have a wide operating temperature range to suit a variety of environments. All Displaytech LCDs are RoHS compliant.

We also offer semi-customization to our standard TFT screens. This is a cost-optimized solution to make a standard product better suit your application’s needs compared to selecting a fully custom TFT LCD. Customizations can focus on cover glass, mounting / enclosures, and more - contact us to discuss your semi-custom TFT solution.

This new range of TFT LCD displays with unique characteristics come with the standard interfaces including MiPi, SPI, RGB, DisplayPort and eDP. However, to aid our customers and increase our flexibility of interfacing we are also offering proprietary interface boards which allow you to simply interface via the HDMI / USBC inputs. If you would like more information on this interface board, then please just contact us.

Another major development, available on most of the new range, is the full active LED dimming backlighting which is a technology improvement on edge lit displays. This new technology allows you to control certain parts of the screen and to optimize colours and shades.

On one side, it pushes the video to the LCD layer but on the other side, it processes the video, decides what the best brightness should be for each and every section of the LCD (divided into zones) based upon the image that is on it. Then it tells each LED what brightness to be for optimisation. The result is that the blacks are darker, the whites are brighter, and everything in between is more in tune with what they should be. And this is happening 60 times per second, wow, what a performance for optimization process!

You can achieve true HDR (High-dynamic-range) and can exceed HDR1000* specs.  The dynamic contrast ratio is virtually unlimited and as you can see can reach 10 Million to one (10M:1) and you can achieve peak brightness that’s daylight readable but have the colour and brightness depth of an OLED display.  We are seeing great interest in these displays in areas such as broadcast, medical and automotive industries as they value the quality of the image and performance that standard TFTs cannot offer.

Orient Display sunlight readable TFT displays can be categorized into high brightness TFT displays, high contrast IPS displays, transflective TFT displays, Blanview TFT displays etc.

The brightness of our standard high brightness TFT displays can be from 700 to 1000 nits. With proper adding brightness enhancement film (BEF) and double brightness enhancement film (DBEF) and adjustment of the LED chips, Orient Display high brightness TFT products can achieve 1,500 to 2,000 nits or even higher luminance. Orient Display have special thermal management design to reduce the heat release and largely extend LED life time and reduce energy consumption.

Our high contrast and wide viewing angle IPS displays can achieve contrast ratio higher than 1000:1 which can make readability under strong sunlight with lower backlight luminance. High brightness IPS displays have been widely accepted by our customers with its superb display quality and it has become one of the best sellers in all our display category.Transflective display is an old monochrome display technology but it has been utilized in our color TFT line for sunlight readable application. Orient Display has 2.4” and 3.5” to choose from.

Blanview TFT displays are the new technology developed by Ortustech in Japan. It can provide around 40% of energy consumption for TFT panels which can use smaller rechargeable or disposable batteries and generate less heat. The price is also lower than traditional transflective TFT displays. Orient Display is partnering with the technology inventor to provide 4.3” and 5.0”.

Of course, Orient Display can also offer traditional RTP (Resistive Touch Panel) of 4-wire, 5-wire, 8-wire through our partners, which Orient Display can do integration to resistive touch screen displays.

LCD Monitor Course II, which kicks off this session, will address certain points one must know to choose the LCD monitor best-suited to one"s needs from the various models available. Part 1 will focus on color gamut. While wide color gamuts are the latest trend in LCD monitors, color gamut is a term that lends itself to misunderstanding. Our hope is that this session will help users better understand the color gamut of LCD monitors and better select, use, and adjust the products.

Note: Below is the translation from the Japanese of the ITmedia article "IT Media LCD Monitor Course II, Part 1" published on November 11, 2008. Copyright 2011 ITmedia Inc. All Rights Reserved.

A color gamut defines a more specific range of colors from the range of colors identifiable by the human eye (i.e., the visible spectrum). While color imaging devices include a wide range of devices, such as digital cameras, scanners, monitors, and printers, since the range of colors they can reproduce varies, the color gamut is established to make these differences clear and to reconcile the colors that can be used in common between devices.

Various methods are used to express (diagram) the color gamut, but the common method used for display products is the xy chromaticity diagram of the XYZ color system established by the International Commission on Illumination (CIE). In an xy chromaticity diagram, the colors of the visible range are represented using numerical figures and graphed as color coordinates. In the following xy chromaticity diagram, the area shaped like an upside-down "U" surrounded by dotted lines indicates the range of colors visible to human beings with the naked eye.

Various standards govern color gamuts. The three standards frequently cited in relation to personal computers are sRGB, Adobe RGB, and NTSC. The color gamut defined by each standard is depicted as a triangle on the xy chromaticity diagram. These triangles show the peak RGB coordinates connected by straight lines. A larger area inside a triangle is regarded to represent a standard capable of displaying more colors. For LCD monitors, this means that a product compatible with a color gamut associated with a larger triangle can reproduce a wider range of colors on screen.

This is a CIE XYZ color system xy chromaticity diagram. The areas enclosed in dotted lines represent the range of colors human beings can see with the naked eye. The ranges corresponding to the sRGB, Adobe RGB, and NTSC standards defining color gamuts appear as triangles connecting their RGB peak coordinates. The color gamut of an LCD monitor"s hardware can be indicated using similar triangles. An LCD monitor is not capable of reproduction (display) of colors outside its color gamut.

The standard color gamut for personal computers is the international sRGB standard prepared in 1998 by the International Electrotechnical Commission (IEC). sRGB has established a firm position as the standard in Windows environments. In most cases, products like LCD monitors, printers, digital cameras, and various applications are configured to reproduce the sRGB color gamut as accurately as possible. By ensuring that the devices and applications used in the input and output of image data are sRGB compatible, we can reduce discrepancies in color between input and output.

However, a look at the xy chromaticity diagram shows that the range of colors that can be expressed using sRGB is narrow. In particular, sRGB excludes the range of highly saturated colors. For this reason, as well as the fact that advances in devices such as digital cameras and printers have led to widespread use of devices capable of reproducing colors more vivid than those allowed under the sRGB standard, the Adobe RGB standard and its wider color gamut have recently drawn interest. Adobe RGB is characterized by a broader range than sRGB, particularly in the G domain—that is, by its ability to express more vivid greens.

Adobe RGB was defined in 1998 by Adobe Systems, maker of the well-known Photoshop series of photo-retouching software products. While not an international standard like sRGB, it has become— backed by the high market share of Adobe"s graphics applications—the de facto standard in professional color imaging environments and in the print and publishing industries. Growing numbers of LCD monitors can reproduce most of the Adobe RGB color gamut.

NTSC, the color-gamut standard for analog television, is a color gamut developed by the National Television Standards Committee of the United States. While the range of colors that can be depicted under the NTSC standard is close to that of Adobe RGB, its R and B values differ slightly. The sRGB color gamut covers about 72% of the NTSC gamut. While monitors capable of reproducing the NTSC color gamut are required in places like video production sites, this is less important for individual users or for applications involving still images. sRGB compatibility and the capacity to reproduce the Adobe RGB color gamut are key points of LCD monitors that handle still images.

The visual differences between Adobe RGB (photo at left) and sRGB (photo at right). Converting a photograph in the Adobe RGB color gamut to the sRGB domain results in the loss of highly saturated color data and loss of tonal subtleties (i.e., a susceptibility to color saturation and tone jumping). The Adobe RGB color gamut can reproduce more highly saturated colors than sRGB color. (Note that the actual colors displayed will vary with factors such as the monitor used to view them and the software environment. The sample photographs should be used for reference only.)

In general, the LCD monitors currently available for use with PCs have color gamuts capable of displaying nearly the entire sRGB gamut, thanks to the specifications for their LCD panels (and panel controls). However, given the rising demand mentioned above for reproducing color gamuts broader than sRGB, recent models have expanded the color gamuts of LCD monitors, with Adobe RGB serving as one target. But how is such expansion of LCD monitor color gamuts taking place?

Improvements in backlights account for a significant proportion of the technologies expanding the color gamuts of LCD monitors. There are two major approaches to doing this: one involves expanding the color gamut of cold cathodes, the mainstream backlight technology; the other involves RGB LED backlights.

On the subject of color-gamut expansion using cold cathodes, while strengthening the LCD panel"s color filter is a quick fix, this also lowers screen luminance by decreasing light transmissivity. Increasing the luminance of the cold cathode to counter this effect tends to shorten the life of the device and often results in lighting irregularities. Efforts to date have overcome these drawbacks to a large extent; many LCD monitors feature cold cathodes with wide color gamuts resulting from modification of their phosphors. This generates cost benefits as well, since it makes it possible to expand the color gamut without major changes in the existing structure.

Use of RGB LED backlights has increased relatively recently. These backlights make it possible to achieve higher levels of luminance and purity of color than cold cathodes. Despite certain disadvantages, including lower color stability (i.e., radiant-heat problems) than a cold cathode and difficulty in attaining a uniform white color across the entire screen, since it involves a mixture of RGB LEDs, these weaknesses have been resolved for the most part. RGB LED backlights cost more than cold-cathode backlights and are currently used in a fairly small proportion of LCD monitors. However, based on their efficacy in expanding color gamuts, the number of LCD monitors incorporating the technology will likely increase. This is also true for LCD televisions.

In passing, many LCD monitors that extol wide color gamuts promote the area ratios of specific color gamuts (i.e., triangles on the xy chromaticity diagram). Many of us have probably have seen indications of attributes such as Adobe RGB rates and NTSC rates in product catalogs.

However, these are only area ratios. Very few products include the entire Adobe RGB and NTSC color gamuts. Even if a monitor featured a 120% Adobe RGB ratio, it would remain impossible to determine the extent of the difference in RGB values between the LCD monitor"s color gamut and the Adobe RGB color gamut. Since such statements lend themselves to misinterpretation, it is important to avoid being confused by product specifications.

To eliminate problems involving labeled specifications, some manufacturers use the expression "coverage" in place of "area." Clearly, for example, an LCD monitor labeled as having Adobe RGB coverage of 95% can reproduce 95% of the Adobe RGB color gamut.

From the user"s perspective, coverage is a more user-friendly, easier-to-understand type of labeling than surface ratio. While switching all labeling to coverage presents difficulties, showing in xy chromaticity diagrams the color gamuts of LCD monitors to be used in color management will certainly make it easier for users to form their own judgments.

With regard to the difference between area labeling and coverage labeling as gauges of an LCD monitor"s color gamut, to use Adobe RGB as an example, in many cases, even a monitor with an Adobe RGB ratio of 100% in terms of area will feature coverage of less than 100 percent. Since coverage impacts practical use, one must avoid the mistake of seeing a higher figure as automatically better.

When we check the color gamut of an LCD monitor, it"s also important to remember that a wide color gamut is not necessarily equivalent to high image quality. This point may generate misunderstanding among many people.

Color gamut is one spec used to measure the image quality of an LCD monitor, but color gamut alone does not determine image quality. The quality of the controls used to realize the full capabilities of an LCD panel having a wide color gamut is crucial. In essence, the capacity to generate accurate colors suited to one"s own purposes outweighs a wide color gamut.

When considering an LCD monitor with a wide color gamut, we need to determine if it has a color-gamut conversion function. Such functions control the LCD monitor"s color gamut based on the target color gamut, such as Adobe RGB or sRGB. For example, by selecting sRGB mode from a menu option, we can adjust even an LCD monitor with a wide color gamut and high Adobe RGB coverage so that the colors displayed on screen fall within the sRGB color gamut.

Few current LCD monitors offer color-gamut conversion functions (i.e., feature compatibility with both Adobe RGB and sRGB color gamuts). However, a color-gamut conversion function is essential for applications demanding accurate color generation in the Adobe RGB and sRGB color gamuts, such as photo retouching and Web production.

For purposes requiring accurate color generation, an LCD color monitor lacking any color-gamut conversion function but having a wide color gamut can actually be a disadvantage in some cases. These LCD monitors display each RGB color mapped to the color gamut inherent to the LCD panel in eight bits at full color. As a result, the colors generated are often too vivid for displaying images in the sRGB color gamut (i.e., the sRGB color gamut cannot be reproduced accurately).

Shown here are examples of an sRGB color gamut photograph displayed on an sRGB-compatible LCD monitor (photo at left) and on an LCD monitor with a wide color gamut but incompatible with sRGB and with no color-gamut conversion function (photo at right). While the photograph at right appears vivid, saturation is unnaturally high in parts of the photo. We also see a significant departure from the colors envisioned by the photographer, as well as so-called memory colors.

In more than a few cases, as expanding LCD monitor color gamuts result in the capacity to reproduce a wider range of colors and more opportunities to check colors or adjusting images on monitor screens, problems such as breakdowns in tonal gradations, variations in chromaticity caused by narrow viewing angles, and screen display irregularities, less conspicuous at color gamuts in the sRGB range, have become more pronounced. As mentioned earlier, the mere fact of incorporating an LCD panel with a wide color gamut does not ensure that an LCD monitor offers high image quality. On this subject, let"s take a close look at various technologies for putting a wide color gamut to use.

First we look at technologies to increase gradation. Key here is the internal gamma-correction function for multi-level gradation. This function displays eight-bit input signals on screen in each RGB color from the PC side after first subjecting them to multi-level gradation to 10 or more bits in each RGB color inside the LCD monitor, then assigning these to each RGB eight-bit color deemed optimal. This improves tonal gradations and gaps in hue by improving the gamma curve.

On the subject of the viewing angle of an LCD panel, while larger screen sizes generally make it easier to see differences, particularly with products with wide color gamuts, variations in chromaticity can be an issue. For the most part, chromaticity variation due to viewing angle is determined by the technology of the LCD panel, with superior ones showing no variation in color even when viewed from a moderate angle. Setting aside the various particulars of LCD panel technologies, these generally include in-plane switching (IPS), vertical alignment (VA), and twisted nematic (TN) panels, listed from smaller to larger chromaticity variation. While TN technology has advanced to the point at which viewing angle characteristics are much improved from several years back, a significant gap remains between this technology and VA and IPS technologies. If color performance and chromaticity variation are important, VA or IPS technology remains the better choice.

A uniformity-correction function is a technology for reducing display irregularities. The uniformity referred to here refers to colors and brightness (luminance) on screen. An LCD monitor with superior uniformity has low levels of screen luminance irregularities or color irregularities. High-performance LCD monitors feature systems that measure luminance and chromaticity at each position on screen and correct them internally.

This is a comparison of monitors with and without uniformity correction. An LCD monitor with uniformity correction (photo at left) has more uniform luminance and color on screen than one lacking uniformity correction (photo at right). The two photographs above have been adjusted to equalize levels to emphasize display irregularities. Actual irregularities would be less conspicuous.

To make full use of an LCD monitor with a wide color gamut and to display colors as the user intended, one needs to consider adopting a calibration environment. LCD monitor calibration is a system for measuring colors on screen using a special-purpose calibrator and reflecting the characteristics of the colors in the ICC profile (a file defining device color characteristics) used by the operating system. Going through an ICC profile ensures uniformity between the color information handled by graphics software or other software and the colors generated by the LCD monitor to a high degree of precision.

Software calibration refers to following the instructions of specialized calibration software to adjust parameters such as luminance, contrast, and color temperature (RGB balance) using the LCD monitor"s adjustment menu, approaching the intended color through manual adjustments. Graphics driver colors are manipulated in some cases in place of the LCD monitor"s adjustment menu. Software calibration features low cost and can be used to calibrate any LCD monitor.

However, variations in precision can arise since software calibration involves manual adjustment. Internally, RGB gradation can suffer because display balance is matched by thinning RGB output levels using software processing. Even so, use of software calibration will likely make it easier to reproduce colors as intended than using no calibration at all.

In contrast, hardware calibration is clearly more precise than software calibration. It also requires less effort, although it can be used only with compatible LCD monitors and entails certain setup costs. In general, it involves the following steps: calibration software controls the calibrator; matching color characteristics on screen with target color characteristics and directly adjusting the LCD monitor"s luminance, contrast, and gamma-correction table (look-up table) at the hardware level. Another aspect of hardware calibration that cannot be overlooked is its ease of use. All tasks through the preparation of an ICC profile for the results of adjustment and registering this to the OS are done automatically.

The EIZO LCD monitors currently compatible with hardware calibration include models in the ColorEdge series. The FlexScan series uses software calibration. (Note: As of January 2011, FlexScan monitors compatible with EasyPIX ver. 2 offer hardware calibration functionality.)

By combining a ColorEdge-series monitor with a calibrator and ColorNavigator special-purpose color-calibration software, one can achieve easy, precise hardware calibration.

In the next session, we will examine LCD monitor interfaces and a number of video interfaces for LCD monitors, including the latest generation of interfaces such as HDMI and DisplayPort.

Though LED and backlit LCD digital signage can produce a wider color gamut and better color accuracy than printed signage, they have some major challenges when used outdoors.

When used in direct sunlight or other bright ambient light, LED and LCD backlit display images can become washed out and difficult to read. To improve visibility and color accuracy in these conditions, a display brightness of between 4,000 to 8,000 nits is required[13]. That can be anywhere from about 5 to 30+ times the brightness of a standard TV, which can fall between 200-1000 nits depending on the addition of HDR.

Increasing the display brightness comes with some major tradeoffs. First and foremost, high-brightness displays consume a lot power. This translates to a greater impact on the environment and higher energy costs for the operator.

Moreover, for LED digital signage, there is a light output variation which means that increases in temperature adversely affect the color accuracy of emitted light. For example, as LED display temperature increases during extended use, the emitted light will have a red spectrum shift where the display images will have a reddish tone. Not only that, but the increasing temperatures can damage the display hardware. Temperature control solutions, such as cooling fans, can be added to prevent these effects from heat production. However, these mechanisms further increase the bulkiness and power consumption of the display.

Another big issue for LED or a backlit LCD displays is the output of additional light pollution from the backlight or LEDs. This manufactured light mixes with the surrounding ambient light and impedes the display"s color accuracy.

When LED and LCD digital signage panels are mass produced in a factory, there are usually some irregularities across all panels in terms of brightness and color production. To create a large video wall application, multiple panels are tiled together. At this point, variances and irregularities become glaringly obvious and detrimental to the messaging on the screen. To achieve color uniformity across all the panels, these variances must be calibrated, sometimes on a regular basis. Most of this can be done easily using well-developed calibration software available through digital signage distributors and manufacturers.

TFT stands for thin-film transistor, which means that each pixel in the device has a thin-film transistor attached to it. Transistors are activated by electrical currents that make contact with the pixels to produce impeccable image quality on the screen. Here are some important features of TFT displays.Excellent Colour Display.Top notch colour contrast, clarity, and brightness settings that can be adjusted to accommodate specific application requirements.Extended Half-Life.TFT displays boast a much higher half-life than their LED counterparts and they also come in a variety of size configurations that can impact the device’s half-life depending on usage and other factors.TFT displays can have either resistive or capacitive touch panels.Resistive is usually the standard because it comes at a lower price point, but you can also opt for capacitive which is compatible with most modern smartphones and other devices.TFT displays offer exceptional aspect ratio control.Aspect ratio control contributes to better image clarity and quality by mapping out the number of pixels that are in the source image compared to the resolution pixels on the screen.Monitor ghosting doesn’t occur on TFT displays.This is when a moving image or object has blurry pixels following it across the screen, resembling a ghost.

TFT displays are incredibly versatile.The offer a number of different interface options that are compatible with various devices and accommodate the technical capabilities of all users.

There are two main types of TFT LCD displays:· Twisted nematic TFT LCDs are an older model. They have limited colour options and use 6 bits per each blue, red, and green channel.

In-plane switching TFT LCDs are a newer model. Originally introduced in the 1990s by Hitachi, in-plane switching TFT LCDs consist of moving liquid pixels that move in contrast or opposite the plane of the display, rather than alongside it.

The type of TFT LCD monitor or industrial display you choose to purchase will depend on the specifications of your application or project. Here are a few important factors to consider when selecting an appropriate TFT LCD display technology:Life expectancy/battery life.Depending on the length of ongoing use and the duration of your project, you’re going to want to choose a device that can last a long time while maintaining quality usage.

Touch type and accuracy.What type of activities are you planning on using your device for? If it’s for extended outdoor use, then you should go with projected capacitive touch as this is more precise and accurate. Touch accuracy is important for industrial and commercial applications.

Image clarity.Some TFT displays feature infrared touchscreens, while others are layered. The former is preferable, especially in poor lighting conditions or for outdoor and industrial applications, because there’s no overlay and therefore no obstructions to light emittance.

The conclusion was that combining the STM32 High performance microcontrollers, with the free STM32 graphics toolchain and Riverdi displays + PCB and then merge all of this into a board support package ready to run TouchGFX, would be a compelling offering.

Designing and developing a product with an embedded user interface (GUI), can be complex, as it involves many building block and disciplines, which all requires expert knowledge. Riverdi offer is covering a lot of them, allowing the customer to focus on the most important part of the development, the GUI Application itself. And remember that this is the face of your product. Choosing such solution, the customer does not need to worry about sourcing components like the display, microcontrollers, memory, etc. or even writing low-level drivers, development the board support package or porting TouchGFX. Its all ready done. What makes cooperation with Riverdi unique is that Riverdi has been able to drive a 1280*800 display resolution in high colors, with a STM32H7 microcontroller and a TouchGFX application showing a smart home UI. This shows that Riverdi is well aware of how to exploit all the capabilities of the STM32 Graphics offering combining hardware and software in a unique solution. From the first business meetings, it was clear that we shared visions of the market for embedded GUIs. And Riverdi proved that they can go from an idea and concept to actual working hardware, very fast.
