I purchased this as a display (version 2.1) for my OctoPrint-running Raspberry Pi 2 with the awesome TouchUI plugin. This display works great, and is higher resolution than the official Raspberry Pi display (1024x600 vs 800x480). The color is fairly accurate although those used to over-saturated LCDs might find it a bit dull. The capacitive touch works well, however there is some error very close to the corners which can cause some mis-clicks but is a small enough area to be avoidable. Everything works out of the box once you set the display information in config.txt, even display rotation and touchscreen event rotation for a portrait orientation.

While having just two cables run to the display to power it, provide the video in, and the touch out back to the pi is convenient, it really pulls a lot of power on the 5V line, about 600-700mA when the display is on in addition to the ~400mA needed by a Pi 3. I would have preferred there to be an external power input so all this current is pulled through the Pi"s traces. Even better if I could power it from 12V like many other HDMI driver boards can. I examined the PCB layout of the display board and it is good, using name brand components from companies like Atmel and TI. The drivers for the LCD power and LED backlight are all rated for 6V absolute maximum so there"s no chance of modding this to use 12V instead of 5V.

The LCD backlight has a convenient switch on the back of the driver board to allow the user to turn on and off the backlight to save power. I found this a curious solution rather than allowing the display to power off based on HDMI input and DPMS standard. This means that when the Pi sits idle long enough, it tries to put the display to sleep but it just turns black-- the backlight is left on so power saving is minimal. What I ended up doing is reworking the board to link the driver chip"s SCDT to !PDO and the LED driver Enable line to be able to power on/off the display via the Pi. Why Waveshare did not design the board like this I don"t understand and that"s my biggest reason for deducting a star from this review.

PIT technology is a patented multi-touch technology. Based on the traditional infrared touch technology and the theory of total internal reflection (TIR), placing the infrared emission diode and reception diode on the lower surface of glass, the infrared beams generated by emission diodes are reflected through a prism light-guide specially designed and transmit across the front glass surface. Compared to traditional infrared touch technology, PIT touch screen has slimmer bezel, lower elevated height, and better multi-touch experience. Impact Display Solutions PIT touch screens have Win8 certification. PIT touch screens support multi-touch capability, allowing more people to touch the screen simultaneously. That allows users to have a better interactive experience. Compared to traditional infrared touch screen, 0.5mm ultralow elevated height enables PIT touch screen recognize human touch very accurately. Ultra-narrow bezel allows near-true flat appearance (as the touch transducers are placed under the screen). Protection performance enhancements are optional: waterproof or vandal-resistant.

As we all know, the biggest advantage of projected capacitive touch screens over other touch screen technologies is in the ease of implementation of feather-touch & multi-touch for gestures, but feather-style touching can lead to unintended activations in conventional projected capacitive touch screens. Adding force sensing overcomes that weakness of PCAPs. Force Sensing Touch Screens implement unintended touch rejection by ‘brushing off’ past accidents and it takes into account finger repositioning before selection. Force-sensing touch screen also enables new hand moves and menu-bringing features you can add to your product to enhance user experience.

Based on proven SAW touch technology, Impact Display Solutions has the capability of offering curved SAW touch screens in sizes of 21.5”, 27”, 32”, 35”, 42”. Furthermore, curved SAW touchscreens inherit and enjoy the benefits of SAW technology such as high reliability, protracted durability, sharp image clarity and vandal proofing. It’s the ideal touch solution for gaming and interactive kiosks.

The Capacitive touch panel is activated with anything containing an inductive load such as a finger or stylus. It allows for multi-touch options. When using the capacitive touch screen, the display needs a separate controller to interface with the touch panel. The display for capacitive touch is brighter since the touch panel is transparent.

The Transmissive polarizer is best used for displays that run with the backlight on all the time. This polarizer provides the brightest backlight possible. If you have a need for a bright backlight with lower power drain, transmissive is a good choice for this TFT LCD display.

Two metallized layers(x-y) are overlaid onto an LCD screen. These thin-film metallic panels have a lower impedance than typical ITO** touch panels. This allows for a higher S/N ratio, wider touch sense margin, and better overall sensitivity.

Insert the TF Card to Raspberry Pi, connect the Raspberry Pi and LCD by HDMI cable; connect USB cable to one of the four USB ports of Raspberry Pi, and connect the other end of the USB cable to the USB port of the LCD; then supply power to Raspberry Pi; after that if the display and touch both are OK, it means drive successfully (please use the full 2A for power supply).

After execution, the driver will be installed. The system will automatically restart, and the display screen will rotate 90 degrees to display and touch normally.

Capacitive touch technology is increasingly used in user interfaces for a variety of devices. A capacitive touch display is created by attaching a capacitive layer on top of a glass panel substrate. These components are then covered with a protective outer layer, and the surface of the device will maintain a static charge. As a person’s finger or a stylus touches the surface, the charge will transfer from the panel surface to the device or finger. This allows the capacitive device to register the touch location.

Thin-film transistor (TFT) LCD capacitive touch screens have become a popular choice when compared to the other leading touch screen technology – resistive touch. While resistive touch screens have been around for a longer time and can be built at a lower cost, capacitive touch displays offer several significant advantages over other display technologies. In this post, we’ll explore what makes capacitive touch technology unique and how it performs across several parameters.

Capacitive touch technology offers excellent screen sensitivity when used with a finger or stylus. The surface of these devices will respond to varying degrees of pressure, as opposed to a resistive touch screen where firm and direct pressure must be used. A TFT LCD capacitive touch screen is also sensitive enough to be used only with fingers without the need for a stylus.

Capacitive stylus devices can be used for added precision and niche applications such as digital drawing. Another related benefit is support for multi-touch operation using multiple fingers simultaneously. This includes advanced gestures such as pinch-zoom that is a popular feature in many device applications today.

TFT LCD capacitive displays are known for their excellent optical quality. The glass substrate that sits below the electrode film transmits most of the available light to the surface resulting in crisp sharpness and display contrast. These screens are also known for outstanding color fidelity that supports the viewing of high-quality images, video, and software content. This also has a positive impact on the user experience when integrated into larger kiosks and interactive displays.

Capacitive touch devices are very stable, with little to no shift in the image being transferred to the screen. This is an important advantage over other display types, as image shift can get worse over time and require manual correction with other types of displays. A capacitive touch device, therefore, does not require the periodic calibrations that are commonly necessary with many older display technologies. Maintaining a stable image is an essential requirement in high-performance display applications, such as those found in the broadcasting and entertainment industries.

The glass substrate of a capacitive touch display is very strong, and the protective layer helps prevent scratches and other marks. Like most displays, a capacitive touch screen can crack if dropped or exposed to significant pressure. It should be noted that a cracked resistive touch screen most often ceases to operate, while a cracked capacitive device will usually maintain some functionality. This has made capacitive screens popular for commercial applications that are exposed to significant wear and tear.

The screen of a capacitive touch device can be completely sealed, preventing contaminants from entering the seams on the outer edges of the display. Preventing dust and condensation from getting inside the display is important for long-term use. This also makes a capacitive touch display easy to clean. Due to the ease of cleaning and other advantages, capacitive touch technology is often used for public digital displays in high-traffic areas.

The sensitivity of a capacitive touch display also contributes to excellent response times. As a user touches the screen at different locations, the surface can register these movements with a high degree of accuracy. A capacitive touch screen also performs very well when the user’s finger or stylus is dragged across the surface. This makes capacitive touch a preferred choice for graphic design and audio-visual applications.

One final advantage of capacitive touch technology is false touch rejection. A resistive display can be easily confused if multiple fingers touch the screen at the same time, making it unable to register accurate movement. The improved sensitivity of a capacitive display increases the ability of the surface to differentiate between multiple points of contact. In addition to enabling the custom gestures, sliding motions, and light touches mentioned above, this also eliminates the potential for a missed touchpoint.

Capacitive touch is a relatively new touchscreen technology that is having a significant impact on the display industry. With several advantages over competing design options, the use of TFT LCD capacitive touch technology is expected to grow significantly in the coming years. This will be an important trend for device manufactures, designers, and end-users to follow as an opportunity to improve product quality and performance.
