bistable lcd displays supplier

High contrast and wide viewing angle: The monochromatic bistable LCD’s contrast ratio is as high as 25:1, viewing angle about 80 degree in all directions.

Bistable Liquid Crystal materials require protection from UV light. A UV blocking material with a minimum 98% cut of at 380nm and lower spectral components is required.

The finished product design should incorporate a transparent cover such as acrylic, polycarbonate etc. to protect the viewing area of the display. Place the protective cover as close to the display bistable module as possible. The protective cover should be sufficient thickness to resist bending.

The power used for screen refreshing is pretty high. So, it will not worthwhile for an application if the screen has to be refreshed more than 20 to 50 times depending on the battery used. Bistable display technology has been used for shelf label and E-reader. Bi-stable LCDs requires the use of a voltage booster. Designing into some environments needs to be cautious, examples: explosive gas. Bistable LCDs are limited to one color of character and one color of background.

Bistable LCDs are reflective and do not require a backlight. This can be a disadvantage in areas with dark ambient light. If the lighting has to be used, it can only use front light instead of backlight. It can be expensive and lose its key advantage of low power.

New Vision Display acquired the ZBD LCD technology – including patents, know-how, employees and facility – on September 20th, 2019. ZBD LCDs are a low-power, reflective, bistable LCD technology that offers paper-like reflectivity, wide viewing angles, wide storage/operating temperatures, and long-term stability at a low cost. ZBDs use standard LCD material with a robust and proven supply chain. Because of their unique advantages, ZBDs are an excellent display solution for battery-operated devices, outdoor environments, and bright lighting conditions. Call us to discuss if ZBD LCDs are the right choice for your project!

The power efficiency offered by bi-stable displays is their primary draw. For example, research conducted by Motorola found that a battery in a PDA can last over 600 times longer on a device that utilises bi-stable technology.

Electronic shelf labels (ESL) using bi-stable technology allow retailers to change product pricing remotely and in real-time. This allows the retailer to be reactive with pricing and promotions, and stay ahead of their competitors. At GTK, our colour bi-stable displays offer the additional benefit of making signage more visually appealing and eye-catching.

In addition to the above benefits, bi-stable displays offer wider viewing angles than most transmissive displays, high contrast ratio and excellent sunlight readability.

Bistable LCD Display offers the perfect display in a world of imperfect LCD technology. Think about this; perhaps in a perfect world automobiles would require no gas; air conditioners in Arizona would require no power; and food crops would require no rain or water. We do not live in a perfect world but there is a LCD display technology that can display an image that requires zero power. Is it possible?

Well, yes and no... the Bistable LCD Display, also called cholesteric liquid crystal (ChLCD), e-paper, and even zero power, do offer a great power savings. They do not require any power to display the image, but there is a need for power to change the image. This unique bi-stable property means that an image placed on the display will remain indefinitely without the need for refreshing as is necessary in an active matrix display such as a TFT LCD Displays or a passive matrix display such as a monochrome character LCDs.

At this time all Bistable LCD displays are custom built to the customer’s specification. This requires a one-time tooling fee and an MOQ (minimum order quantity).

Zero power displays are reflective and do not require a backlight. This can be a disadvantage in areas with dark ambient light, but the plus side is they are very readable in direct sunlight. This is a great advantage over many other display technologies that have to compete with sun light, making the other displays difficult to read.

Some of the bistable LCD display is equipped with on-board RAM memory to store the image. They can be manufactured as a Chip on Glass (COG), Chip on Flex (COF) and Chip on Board (COB).

The largest possible glass size at this time is 18 inches. The product designer can build the custom bistable display to a size that meets their design requirements.

A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directlybacklight or reflector to produce images in color or monochrome.seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character positive LCD with a backlight will have black lettering on a background that is the color of the backlight, and a character negative LCD will have a black background with the letters being of the same color as the backlight. Optical filters are added to white on blue LCDs to give them their characteristic appearance.

Glass substrate with ITO electrodes. The shapes of these electrodes will determine the shapes that will appear when the LCD is switched ON. Vertical ridges etched on the surface are smooth.

LCDs are used in a wide range of applications, including LCD televisions, computer monitors, instrument panels, aircraft cockpit displays, and indoor and outdoor signage. Small LCD screens are common in LCD projectors and portable consumer devices such as digital cameras, watches, calculators, and mobile telephones, including smartphones. LCD screens have replaced heavy, bulky and less energy-efficient cathode-ray tube (CRT) displays in nearly all applications. The phosphors used in CRTs make them vulnerable to image burn-in when a static image is displayed on a screen for a long time, e.g., the table frame for an airline flight schedule on an indoor sign. LCDs do not have this weakness, but are still susceptible to image persistence.

Now, it wasn’t developed in Farnborough, it was developed at a research lab near Malvern in the UK. I first saw it for myself at Display Week in 1998 and was impressed. The technology’s full name was the Zenithal Bistable Display and it was interesting because although it was an LCD, it was truly bistable – once the LC crystals had been ‘nudged’ into a particular configuration, they would stay there without power being applied There’s a good explanation of the way that it works here. E Ink has the same property, but E Ink also needs an active matrix, whereas ZBD uses passive matrix addressing can be multiplexed over many lines because of the ‘memory’ effect.

However, the ESL market was increasingly moving to EPD displays like E Ink because of the ‘paper-like’ look, so in 2019, the ZBD technology was acquired by New Vision Display, a developer of custom LCDs that is headquartered in Shenzen but has facilities around the world. I reported on New Vision when it announced an interesting reflective LCD earlier this year (Reflections on the Desktop – and Outside).

The ZBD technology is basically simple, but there are some critical processes such as the alignment layer as the LC anchoring needs to be consistent. At the moment, the firm can make bistable reflective LCDs up to 16″ with up to 200ppi and because tooling costs are low, it is able to make custom displays with surprisingly low volume because the NRE charges are likely to be very economical.

There are a number of applications gaining attention including handheld devices and even high end CE devices. It can be used in digital signage and an intriguing application is in Industrial switches. These can include LCDs that maintain their state even after power failures – a key feature for this kind of use.

As I mentioned in the article on the earlier reflective LCD, New Vision is very interested in electronic licence plates and in the past we have reported that the ZBD technology is particularly robust mechanically, which is not true of all of the bistable LCD technologies. Obviously, where there is a lot of vibration this can be really important and the technology needs to work in a wide range of temperatures. The ZBD technology can be switched down to -10 deg C and up to 90 deg C and can maintain the image down to -40 deg C and up to over 100 deg C. The

For the different requirements and information content of national and city transport, we have designed standard display types based on our many years of experience. These differ mainly in the number of displays, the number of lines or the display board layout. This allows the user more flexibility in the design of a passenger information system. The standard models offer an ideal basis which can be expanded with individual features such as coloured Highlights.

The transflective characteristic give the LCD displays optimal readability in all weather conditions – including in direct sunlight. A light sensor regulates the display brightness automatically and an energy management system contributes to high environmental performance and lower operating costs.

Application:Passenger guiding systems, platform displays, advance notice, real-time information, arrival and departure boards, train position indicator

Geameleon – bistable display technologyThe dynamic Geameleon destination display offers the possibility to show real-time information using very little power.

This display is based on a bistable technology which is characterised by very low power consumption. According to the requirements, the displays can be produced in different sizes and the user has the possibility to choose between monochrome or colour layouts. Specifically designed for outdoor areas, the display can be mechanically integrated in various ways. For example on lamp posts, platform roofs or walls and so on. The system can also be run in a self-sufficient manner using solar energy.

Application:Passenger guiding systems, platform displays, advance notice, real-time information, arrival and departure boards, train position indicator

TFT TechnologyWith the TFT train destination displays we meet the new requirements on passenger information displays. The display systems promptly and accurately show the train departure times and additional information such as news tickers, weather, journey connection information and advertising can be shown as alternating Images.

As a specialist in outdoor applications, we place a lot of value on the readability and durability of these displays. We use very high-quality TFT displays from leading manufacturers with a brightness of 2,000 cd/m²; these are very legible even under direct solar radiation. With an extended temperature range and guaranteed durability these displays are an ideal and reliable component.

This is the same technology that is being use on the Amazon Kindle and other e-readers. These zero-power displays are now available to OEM (Original Equipment Manufacturers). Their cost and MOQ’s (Minimum Order Quantities) are decreasing as they become more popular. This makes the new technology more and more attractive for consumer products that require minimal power usage.

Cholesteric liquid crystal displays offer an ultra wide viewing angle; in fact, the display is readable from a full 180 degrees. This exceeds the viewing angle of every other type of LCD display. The reason this is possible is because the technology does not require a polarizer. Without the polarizer—which naturally limits viewing angle—this means you can read the display from extreme high, low, left, or right angles.

The display offers a very sharp contrast between the background and the character segments. The contrast is very close to that of printed type on white paper; that is another quality that speaks to its readability. Bi-stable displays are also versatile in that they are not limited to black letters on a white background. The segments can be other colors and the display can run in negative mode. (Negative mode is when the characters are light in color and the background is darker.)

Bi-stable displays require the use of a booster or charge pump. There are certain conditions or environments wherein this technology is not recommended. Specifically, it can be dangerous in situations where there may be explosive gas.

At this time, while Bi-stable LCD’s can use a wide range of colors for the background and the segments they are limited to one color of character and one color of background. Unlike TFT (thin-film-transistor) and OLED (organic light emitting diode) displays, which allow the user to display 64,000 or more colors.

There is new technology being developed to add colors as an option to these displays. Research by Gamma Displays (http://gammadynamics.net/) in Tempe Arizona has developed a prototype bi-stable display that is able to produce a multitude of colors. Although this is not in production at this time, it could be incorporated in the next generation of tablets or laptops.
