cholesteric lcd display price

The bistable liquid crystal screen has the advantages of energy saving, lightweight, flexibility, etc., and has important application value in the fields of portable display devices such as e-books, smart cards, and writing tablets, drawing boards, blackboards and whiteboards, and educational toys etc.

Howeasy company’s liquid crystal writing screen makes full use of the bistable characteristics of the liquid crystal molecules and utilizes the reflection display principle of the liquid crystal molecules. It does not require a polarizing plate and a color filter, does not require a backlight, and can display a stable content without an external electric field for a long time, so the power consumption is extremely low. And it is widely used in the field of high-grade electronic paper and writing board.

Howeasy’s LCD writing screen is self-developed, self-produced, with exclusive formula and complete intellectual property. Our writing film has the advantages of high brightness, high contrast, high writing precision, scratch resistance, adjustable thickness and display color, good flexibility, etc., and can be customized into different sizes according to the needs of customers.

A cholesteric liquid-crystal display (ChLCD) is a display containing a liquid crystal with a helical structure and which is therefore chiral. Cholesteric liquid crystals are also known as Bragg Reflection).

The technology is characterized by stable states i.e. focal conic state (dark state) and planar state (bright state). Displays based on this technology are called “bistable” and don’t need any power to maintain the information (zero power). Because of the reflective nature of the ChLCD, these displays can be perfectly read under sunlight conditions.

A US company, Kent Displays, has developed "no power" Liquid Crystal Displays using Polymer Stabilized Cholesteric Liquid Crystals: these are known as ChLCD screens.mobile phone, allowing it to change colours, and keep that colour even when power is cut off.

KDI has world class manufacturing expertise in roll to roll manufacturing of liquid crystal films, face shield lenses, and other functional flexible materials in including the award winning flexible Boogie Board eWriter LCD films.

The eWriter works on the principle of anisotropic flow, a unique feature of cholesteric liquid crystals, in which crystals flow at different rates, depending on the direction of pressure being applied.

(PhysOrg.com) -- Currently the screens of e-readers come in two colors, black and white. While the Nook does have a color version out but that screen is an LCD and not an e-ink. While for a while that did create a debate about eyestrain but other companies are looking to catch up to the color.

Fujitsu recently demonstrated a prototype of their next generation cholesteric LCD color digital paper module at the International Digital Publishing Expo. The machine uses a set of Cholesteric liquid crystals to create the display. Cholesteric liquid crystals are different from other methods of creating color LCD displays because this method does not require polarizing plates, reflecting plates, color filters or back lights in order to create the display, which allows them to be thinner than other LCD options.

The trial model, which weighs only weighs 220g, is running a Linux-based operating system, unlike previous versions put out by Fujitsu that used Windows. This new model has an enhanced processing speed, with a write speed of 0.7 seconds and the complete elimination of dithering on the 4,096-color range display that is 8" on the diagonal. The final screen resolution is 157 dpi with a contract ratio of 8:1.

Description:This is a 240x160 reflective cholesteric liquid crystal display (ChLCD) from Kent Displays. The most distinguishing feature of a ChLCD is its ability to retain its image even when the LCD is not powered, similar to e-ink technology. This makes the LCD a great fit for portable battery-powered projects. Bistable, sunlight readable, and easy to integrate, the 240x160 (1/8 VGA) is truly a unique LCD display solution.

Integrated into the display is an embedded controller which generates the unique ChLCD drive waveforms and provides automatic temperature compensation. Communication with the controller is achieved through an SPI-compatible interface, which means a minimal number of I/O resources are needed to control the display.
