Liquid crystal display and electronic device

Abstract

The invention relates to a liquid crystal display comprising two glass substrates, two transparent electrode layers, and an AM-TFT substrate including the second glass substrate and the second transparent electrode layer, wherein the second transparent electrode layer includes a pixel electrode and an AM-TFT, and the AM-TFT is disposed on the second glass substrate and connected to the pixel electrode; the first and second glass substrates are spaced apart up and down; the first and second transparent electrodes are oppositely disposed between the first and second glass substrates; a molding frame is arranged around the first and second transparent electrodes; a sealing cavity is formed between the molding frame and the first and second transparent electrodes; a vertical alignment orientation layer is disposed on the first transparent electrode layer and in a serrated or wavy shape; a parallel alignment orientation layer is disposed on the second transparent electrode layer; liquid crystal is filled in the sealing cavity; and the two polarizers are respectively disposed on the outer sides of the first and second glass substrates. The product provided by the invention can realize high resolution, high contrast, fast response speed, low power consumption, high temperature and high humidity environment resistance, basically no electricity when maintaining information display, andonly power consumption when refreshing display content.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal displays, and in particular relates to a liquid crystal display and electronic equipment. Background technique [0002] The current mainstream AM-TFT (active matrix thin film transistor) liquid crystal display needs to drive LED backlight, AM-OLED needs to drive organic light-emitting materials, the display device consumes a lot of power, and requires the controller to continuously scan and refresh to maintain the display state, and Keeping the same display screen for a long time will lead to problems such as display blurring and afterimages, and the service life will be greatly reduced, and there will be problems such as insufficient brightness, poor visual effect or high power consumption and low reliability under strong sunlight. , not suitable for outdoor display and low power consumption display field, in addition, the AC drive of the backlight and the display constantly scan and refre...

Problems solved by technology

[0003] Electronic paper technology is electrophoretic display. Its principle is to drive the particles with dyes in the microcapsules by an external electric field, which are positively charged white dye particles and negatively charged black dye particles, so as to realize black and white display. This technology The main problem is that the response speed is slow, the operating temperature range is only limited to 0-50 degrees Celsius, it cannot withstand high temperature and high humidity environment, and the service life is short

[0004] Low-power outdoor total reflection LCD technology is to make a layer of internal reflection layer on the traditional AM-TFT array backplane, with optical films such as scattering film and phase difference compensation film, to manufacture a total reflection LCD display without backlight, but The controller of this technology still needs to constantly scan and refresh to maintain the display state, and maintaining the same display screen for a long time will cause problems such as display blur and afterimage, resulting in reduced service life, which is not yet a true ultra-low power consumption and environmental protection LCD Monitor
