Problems solved by technology

However, this driving method still requires a digital-to-analog converter. When the number of bits of display data increases, the circuit complexity and chip area of ​​the digital-to-analog converter will grow exponentially, so that the hardware cost of the digital-to-analog converter will also grow exponentially

Embodiment Construction

[0079] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments and related drawings.

[0080] figure 1 It is a schematic diagram of the relative relationship between the reflectivity of the bistable liquid crystal and the root mean square value of the voltage. Please refer to figure 1 , it is known through experiments that the reflectivity of the bistable liquid crystal is based on the root mean square value (root mean square, RMS), so if the root mean square value of the voltage difference received by each pixel can be effectively controlled by adjusting the pulse wave of the driving signal, the reflectivity of the bistable liquid crystal (that is, the reflectivity of each pixel can be adjusted) displayed grayscale value). Based on the consideration of the response speed, the root mean square value of the voltage difference received by each ...

Abstract

The invention relates to a bistable liquid crystal display, which comprises a display panel, a plurality of row material drivers and a plurality of column material drivers, wherein each row material driver is used for receiving a plurality of phase control signals, first high driving voltage, first low driving voltage and a display material; and one of the phase control signals is selected according to the display material, and according to the selected phase control signal, the first high driving voltage and the first low driving voltage are alternately output to form a row driving signal transmitted to the display panel. Each column material driver is used for receiving one of the phase control signals, the second high driving voltage and the second low driving voltage, and according to the received phase control signal, the second high driving voltage and the second low driving voltage are alternately output to from a column driving signal transmitted to the display panel.

Description

technical field [0001] The present invention relates to a display, and in particular to a bistable liquid crystal display. Background technique [0002] At present, liquid crystal displays with superior characteristics such as high image quality, good space utilization efficiency, and low power consumption have gradually become the mainstream of the market. Among liquid crystal displays, bistable liquid crystal (such as cholesteric liquid crystal) display is a new type of display technology with advantages such as high brightness, high contrast, power saving, memory, wide viewing angle, and no flickering. In this case, the display panel can continuously display the previously written images, so that the power consumption of the bistable liquid crystal display will be lower than that of the transmissive liquid crystal display, so that the application of the bistable liquid crystal display is gradually being valued. [0003] Since the bistable liquid crystal will change to re...
