Embedded touch-sensitive type multi-steady-state liquid crystal device

Abstract

The invention relates to an embedded touch-sensitive type multi-steady-state liquid crystal device. The device adopts an embedded touch-sensitive mode, and integrates a capacitive-type touch-sensitive sensing layer with a multi-steady-state liquid crystal box, and the capacitive-type touch-sensitive sensing layer and the multi-steady-state liquid crystal box can share some of components (such as a substrate and an electrode); liquid crystal molecules in the multi-steady-state liquid crystal box are distributed stably, so the water ripple phenomenon does not appear in the touch-sensitive process, and the picture memory and maintaining state do not need to be continuously powered so as to achieve zero power consumption display; a liquid crystal display control module and a touch-sensitive sensing control module are set and are communicated with a host computer, so that the touch-sensitive sensing input and processing and the like as well as the display output are staggered in time and independently of each other, thereby completely solving the problem of the mutual interference of touch-sensitive sensing components and a display circuit, and achieving the purposes of strong anti-interference ability, smaller water ripple, high stability, and good display effect.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to an embedded touch-type multi-stable liquid crystal display device. Background technique [0002] Due to the development of mobile technology, many electronic devices begin to pursue lightness, simplicity and low power consumption, so that users can use them anytime, anywhere and for a long time. The display with built-in touch screen is a display device with coordinate input, and its simple structure meets the requirement of convenience. Ordinary monitors cannot meet the requirements of low power consumption, but multi-stable liquid crystal displays can achieve low power consumption display, even if the power is cut off, the display state can still be maintained. [0003] It has been reported before that the multi-stable display embedded with a resistive touch layer has the following problems: when the touch is pressed, the thickness of the liquid crystal display will change an...

Ordinary displays cannot meet the requirements of low power consumption, but multi-stable liquid crystal displays can achieve low-power display, even if the power is cut off, the display state can still be maintained

[0003] It has been reported before that the multi-stable display embedded with a resistive touch layer has the following problems: when the touch is pressed, the thickness of the liquid crystal display will change and water ripples will occur; it can be displayed after power off, but the displayed content will be changed due to the pressure And destruction, not stable; in addition, it cannot realize multi-finger monitoring, and cannot realize practical control modes such as screen scaling and rotation.

[0004] It has also been reported that if the method of embedding a capacitive touch layer in a non-multistable liquid crystal display is used, although the above-mentioned disadvantages can be avoided, the method of embedding a capacitive touch layer is susceptible to external interference, and the display circuit of a non-multistable display When working, it will interfere with the work of the capacitive touch layer, there is a serious mutual interference problem, and the display effect is not ideal. At present, there is no better solution
