cholesteric lcd display for sale

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.

This is a 320x240 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, this 320x240 (1/4 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.

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.

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 chiral nematic liquid crystals.

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.
