How many times did you start to plan a project and thought to yourself “if only I had a display that can fit within this design”? How many times did you alter the whole design because there were no displays available on the market that went with your idea?

Liquid crystal display (LCD) screens seem to be incorporated in almost every electronic product imaginable these days. Initially they were seen as an expensive luxury for top of the range products, but as manufacturing issues have been ironed out and new innovations have been made available to nullify some of their drawbacks, their performance has improved almost as fast as their price has dropped. Displays provide the easiest method of viewing relevant and often complex information about the status of applications and equipment. In some cases, they also allow us to control the application through touch. One of the most appealing things about LCD displays is their flexibility. They can be produced in almost any size and shape to fit the required application and this flexibility allows them to be used in many different situations and environments.

The cover lens has to be situated in front of the LCD display. It can be fixed in place with an air gap or be optically bonded to the LCD. While using an air gap is cheaper than optical bonding, it is inferior in almost every other way, especially if the display is to be used outside or in other areas where there is high ambient luminance. The air gap causes repeat refraction and reflection between the three different components of the display (LCD, air gap, cover lens), meaning that some of the light from the display is reflected back to it, impacting the intensity and clarity of the image.

As well as the treatments mentioned above, other methods can be used to provide different benefits to LCD displays. For example, A layer of nano-chemical material can be coated onto the surface of the glass to minimise its surface tension. This coating reduces the contact area between dust and the glass surface by 90%, making the glass hydrophobic, oil-resistant, and fingerprint-resistant, while keeping the screen clear and readable for a longer period of time. Alternatively, an

Each application has its own requirements from an LCD screen. These requirements could depend on the environment where the display will be situated, the user’s reading position or how durable the display has to be. Choosing the correct cover lens and treatments make it possible to tailor the display to the exact needs of each application and get the best possible optical performance out of every LCD display.

Normally it was defined 4 angles to correspond with 3, 12, 9, and 6 o’clock respectively. So, you can find the 6 o’clock or 12 o’clock parameter in the LCD datasheet.

Viewing Angle is the angle with respect to the Z-axis in a certain direction and marked by θ (θU means upper View Angle). LCD Viewing Angle describes the maximum watching angle, and it is one of the key indicators with the display module.

The LCD bias angle is the angle perpendicular from which the display is best viewed. (See Fig.2) This angle is determined when the display is designed and can be set at any angle or orientation. The orientation of the bias angle of LCD displays is often stated with reference to a clock face. If the offset is above the display, it is referred to as a 12:00 or Top view.

The LCD viewing angle is the angle formed on either side of the bias angle, where the contrast of the display is still considered acceptable. Generally, this contrast is specified as 2:1 for monochrome LCD and 10:1 for color LCD.

Generally, displays are optimized for straight-on viewing. Either a 6:00 or 12:00 module may be used, and the contrast voltage can be adjusted slightly to optimize the display for that viewing position. In the above example, the viewing angles of both 6:00 and 12:00 modules actually overlap the perpendicular (or straight on) viewing position.

The LCD is positioned at the nominal viewing position and the pot is adjusted to obtain the desired LCD appearance. The voltage on the VL pin is now measured and a pair of resistors are chosen to produce this voltage in the production units.

– Positive LCD to Negative LCD (When the LCD is used indoor or dark environment, the contrast will increase a lot, but it will not display well with ambient light only, it is also more expensive)

When a LCD is high density with the segments/icons or very crowded, some customers also complains the viewing angle or contrast are not good. The reason is for crowded display, the layout can be long and thin. The voltage drop along the layout can be big. The solutions are:

While displays were previously limited to posters, signs and window displays, today’s technology has extended the possibilities to LCD digital displays. By incorporating these digital screens into your retail display system, you can make your marketing to stand out from the crowd.

LCD digital displays are instantly eye-catching. With bright colours, moving images and soundtracks, they attract and hold attention, providing a vital opportunity to convey your message. What your screen portrays will depend on the nature of your business and is limited only by your imagination. Examples could include a video of your products in action or an advertisement for an upcoming promotion. You can easily vary the content to provide ongoing interest, and after the initial investment, you can simply update your content as your promotions and products change. Over time, this approach can save money, as it reduces the need for print runs.

As with all marketing, where you place digital screens is important. There is a range of LCD digital displays available at Assigns, including options for wall-mounted or free-standing units. Options for their location might include near the entrance so everyone who enters will see it, or near the products you are promoting to draw customers over. Whatever you choose, the robust design and toughened glass will ensure your investment lasts for many years to come. Assigns also gives you the option of tablet holders, enabling you to incorporate several small screens into your marketing strategy.

When preparing your LCD digital displays, take the time to create content of a professional standard. High-quality images and videos will look impressive and are likely to have a positive bearing on your customers’ buying decisions. If you are also using audio content, take the time to ensure the volume is right, particularly if there are voices involved. You need to make sure your customers can clearly hear the audio, but content that is too loud may be off-putting to customers.

Don’t be afraid to experiment with your digital displays. Because the content is relatively inexpensive to produce and is easy to change, it is the ideal media for testing new ideas. By scheduling digital promotions at certain times, you can quickly see the impact on your sales, allowing you to build on the success of a promotion or easily discard an idea that doesn’t work.

LCD digital displays are still a fairly new form of promotion, and now is the ideal time to explore it. Digital screens convey an impression of a company that is innovative and looking to the future. It is likely to become increasingly popular and will undoubtedly develop further as fast as technology allows.

The use of liquid crystal displays (LCDs) in user interface assemblies is widespread across nearly all industries, locations, and operating environments. Over the last 20 years, the cost of LCD displays has significantly dropped, allowing for this technology to be incorporated into many of the everyday devices we rely on.

The odds are high you are reading this blog post on a laptop or tablet, and it’s likely the actual screen uses LCD technology to render the image onto a low-profile pane of glass. Reach into your pocket. Yes, that smartphone likely uses LCD technology for the screen. As you enter your car, does your dashboard come alive with a complex user interface? What about the menu at your favorite local drive-thru restaurant? These are some everyday examples of the widespread use of LCD technology.

But did you know that the U.S. military is using LCD displays to improve the ability of our warfighters to interact with their equipment? In hospitals around the world, lifesaving medical devices are monitored and controlled by an LCD touchscreen interface. Maritime GPS and navigation systems provide real-time location, heading, and speed information to captains while on the high seas. It’s clear that people’s lives depend on these devices operating in a range of environments.

As the use of LCDs continues to expand, and larger screen sizes become even less expensive, one inherent flaw of LCDs remains: LCD pixels behave poorly at low temperatures. For some applications, LCD displays will not operate whatsoever at low temperatures. This is important because for mil-aero applications, outdoor consumer products, automobiles, or anywhere the temperature is below freezing, the LCD crystal’s performance will begin to deteriorate. If the LCD display exhibits poor color viewing, sluggish resolution, or even worse, permanently damaged pixels, this will limit the ability to use LCD technologies in frigid environments. To address this, there are several design measures that can be explored to minimize the impact of low temperatures on LCDs.

Most LCD displays utilize pixels known as TFT (Thin-Film-Transistor) Color Liquid Crystals, which are the backbone to the billions of LCD screens in use today. Since the individual pixels utilize a fluid-like crystal material as the ambient temperature is reduced, this fluid will become more viscous compromising performance. For many LCD displays, temperatures below 0°C represent the point where performance degrades.

Have you tried to use your smartphone while skiing or ice fishing? What about those of you living in the northern latitudes - have you accidently left your phone in your car overnight where the temperatures drop well below freezing? You may have noticed a sluggish screen response, poor contrast with certain colors, or even worse permanent damage to your screen. While this is normal, it’s certainly a nuisance. As a design engineer, the goal is to select an LCD technology that offers the best performance at the desired temperature range. If your LCD display is required to operate at temperatures below freezing, review the manufacturer’s data sheets for both the operating and storage temperature ranges. Listed below are two different off-the-shelf LCD displays, each with different temperature ratings. It should be noted that there are limited options for off-the-shelf displays with resilience to extreme low temperatures.

For many military applications, in order to comply with the various mil standards a product must be rated for -30°C operational temperature and -51°C storage temperature. The question remains: how can you operate an LCD display at -30°C if the product is only rated for -20°C operating temperature? The answer is to use a heat source to raise the display temperature to an acceptable range. If there is an adjacent motor or another device that generates heat, this alone may be enough to warm the display. If not, a dedicated low-profile heater is an excellent option to consider.

Made of an etched layer of steel and enveloped in an electrically insulating material, a flat flexible polyimide heater is an excellent option where space and power are limited. These devices behave as resistive heaters and can operate off a wide range of voltages all the way up to 120V. These heaters can also function with both AC and DC power sources. Their heat output is typically characterized by watts per unit area and must be sized to the product specifications. These heaters can also be affixed with a pressure sensitive adhesive on the rear, allowing them to be “glued” to any surface. The flying leads off the heater can be further customized to support any type of custom interconnect. A full-service manufacturing partner like Epec can help develop a custom solution for any LCD application that requires a custom low-profile heater.

With no thermal mass to dissipate the heat, polyimide heaters can reach temperatures in excess of 100°C in less than a few minutes of operation. Incorporating a heater by itself is not enough to manage the low temperature effects on an LCD display. What if the heater is improperly sized and damages the LCD display? What happens if the heater remains on too long and damages other components in your system? Just like the thermostat in your home, it’s important to incorporate a real-temp temperature sensing feedback loop to control the on/off function of the heater.

Another important consideration when selecting a temperature sensor is how to mount the individual sensors onto the display. Most LCD displays are designed with a sheet metal backer that serves as an ideal surface to mount the temperature sensors. There are several types of thermally conductive epoxies that provide a robust and cost-effective way to affix the delicate items onto the display. Since there are several types of epoxies to choose from, it’s important to use a compound with the appropriate working life and cure time.

For example, if you are kitting 20 LCD displays and the working life of the thermal epoxy is 8 minutes, you may find yourself struggling to complete the project before the epoxy begins to harden.

Before building any type of prototype LCD heater assembly, it’s important to carefully study the heat transfer of the system. Heat will be generated by the flexible polyimide heater and then will transfer to the LCD display and other parts of the system. Although heat will radiate, convect, and be conducted away from the heater, the primary type of heat transfer will be through conduction. This is important because if your heater is touching a large heat sink (ex. aluminum chassis), this will impact the ability of the heater to warm your LCD display as heat will be drawn toward the heat sink.

Before freezing the design (no pun intended) on any project that requires an LCD display to operate at low temperatures, it’s critical to perform low temperature first. This type of testing usually involves a thermal chamber, a way to operate the system, and a means to measure the temperature vs time. Most thermal chambers provide an access port or other means to snake wires into the chamber without compromising performance. This way, power can be supplied to the heater and display, while data can be captured from the temperature sensors.

The first objective of the low-temperature testing is to determine the actual effects of cold exposure on the LCD display itself. Does the LCD display function at cold? Are certain colors more impacted by the cold than others? How sluggish is the screen? Does the LCD display performance improve once the system is returned to ambient conditions? These are all significant and appropriate questions and nearly impossible to answer without actual testing.

As LCD displays continue to be a critical part of our society, their use will become even more widespread. Costs will continue to decrease with larger and larger screens being launched into production every year. This means there will be more applications that require their operation in extreme environments, including the low-temperature regions of the world. By incorporating design measures to mitigate the effects of cold on LCD displays, they can be used virtually anywhere. But this doesn’t come easy. Engineers must understand the design limitations and ways to address the overarching design challenges.

A full-service manufacturing partner like Epec offers a high-value solution to be able to design, develop, and manufacture systems that push the limits of off-the-shelf hardware like LCD displays. This fact helps lower the effective program cost and decreases the time to market for any high-risk development project.

Today’s LCD displays are thinner and more immersive than ever. LCD technologyis continuously evolving to improve the touch response and quality of the display. Most displays are made of glass which is extremely thin in shape typically about 0.3-0.7 mm. In LCDs, a glass substrate is used to build the TFT (Thin-film transistors) layer that controls a color filter layer and liquid crystals.

For production efficiency, manufacturers are using large-sized substrates to cut into the appropriate size requirements of the product for instance LCD display panels are produced on top of a large substrate. The glass substrates that are the foundation of panels are called ‘Mother Glass’ and the generation is determined based on the size of the mother glass.

LCD glass substrate is a specialized glass used in thin-film transistors (TFTs) LCDs to form the display of various products such as personal computers, laptops, mobile phones, game consoles, automotive navigation systems, and digital cameras/camcorders. LCD glass substrate layers consist of liquid crystals, a color filter, a polarizer, TFT, and a TFT substrate.

The demand for high-resolution televisions is rapidly increasing as LCD technology is continuously growing. LCD glass substrates are widely used in televisions due to the usual size of televisions. Nowadays consumers are preferring bigger and wider televisions to enjoy vivid and fine pictures even in very large screen sizes.

TVs are usually bigger and wider compared to computers and laptops which results in increasing demand for LCD glass substrates for high-definition (HD) visuals and images.

New technological advancements in displays with higher resolution such as 4K and 8K TVs are being developed one after another which can create new pathways for the LCD glass substrates.

LCD Glass substrate enables high-resolution and rich color contrast for a better experience. The rapid growth in the television industry with large-sized screens and ultra-high definition (UHD) is likely to propel the demand for LCD glass substrates.

With this rapid growth in TV and laptop production, the globalLCD glass substrates market size was valued at USD 7879.5 million in 2020 and is anticipated to reach USD 10090 million by 2028, expanding at a CAGR of 4.2% during the forecast period, 2021–2028.
