Touch type smectic liquid crystal display

Abstract

The invention discloses a touch smectic-phase liquid crystal display which comprises a first base body layer and a second base body layer. A mixing layer is arranged between the first base body layer and the second base body layer, a first conductive electrode layer is arranged on the side facing the mixing layer, of the first base body layer, a second conductive electrode layer is arranged on the side facing the mixing layer, of the second base body layer, the first base body layer and the second base body layer each consists of multiple displaying electrodes and multiple touch electrodes, the displaying electrodes are connected with a displaying controller, the touch electrodes are connected with a touch controller, all displaying electrodes of the first conductive electrode layer and all displaying electrodes of the second conductive electrode layer form a pixel point array for multi-stable displaying, and all touch electrodes of the first conductive electrode layer and all touch electrodes of the second conductive electrode layer form a sensing point array for sending touch. Under the condition that a touch panel is not arranged, the touch smectic-phase liquid crystal display has multi-stable displaying and touch functions and is light, thin, free of interference and good in displaying effect.

Description

technical field [0001] The invention relates to a smectic liquid crystal display, in particular to a smectic liquid crystal display which integrates a multi-stable display function and a touch control function without adding an external touch panel. Background technique [0002] For convenience in operation, people use a touch screen instead of a mouse or a keyboard. The touch screen is composed of a touch sensing element and a touch controller. The touch sensing element is used to detect the user's touch position and send the detected touch position signal to the touch controller. The main function of the touch controller is to receive touch sense The touch position information sent by the measuring element is converted into contact coordinates and then sent to the CPU for corresponding processing. At the same time, the touch controller is also used to receive and execute instructions from the CPU. According to different types of touch sensing elements, touch screens can b...

Problems solved by technology

It can be seen from the actual implementation that the disadvantage of the In-cell touch panel technology is that since the touch sensor is embedded in the liquid crystal pixel, the area available for the display of the liquid crystal pixel will be reduced, resulting in a deterioration of the image quality. In addition, Since the touch sensing layer 326 is designed near the liquid crystal layer 323 and the TFT array layer 324, the touch sensing layer 326 will receive more noise, which will affect the sensing effect, and solving technical difficulties such as anti-noise interference makes In -The entry threshold of cell touch panel technology is too high
