Abstract

The invention discloses a dual-face display smectic phase liquid crystal color display which comprises a liquid crystal display module; the liquid crystal display module comprises a first base layer and a second base layer; a mixed layer is arranged between the first base layer and the second base layer; the mixed layer is mixed from smectic phase liquid crystal, a conductive object and an isolating object or comprises mixture which is packaged in a polymer structure and consists of the smectic phase liquid crystal, the conductive object and the isolating object; one side of the first base layer which is towards the mixed layer is provided with a first conductive electrode layer; one side of the second base layer which is towards the mixed layer is provided with a second conductive electrode layer; and one side of the first base layer or one side of the second base layer is provided with a color pixel layer. According to the dual-face display smectic phase liquid crystal color display, an image can be displayed on a front face and a rear face simultaneously, so that a dual-face display effect is realized, the image effects displayed on dual faces are good; and in addition, the dual-face display smectic phase liquid crystal color display has a high light utilization rate, no radiation, low energy consumption, light weight and strong display contrast, is low in cost, and can serve as an electronic paper product, an advertising device and the like.

Description

technical field [0001] The invention relates to a smectic phase liquid crystal display device, in particular to a smectic phase liquid crystal display capable of displaying images on both sides in full color. Background technique [0002] Liquid crystal display is currently one of the most widely used and most promising flat panel display devices. [0003] Traditional liquid crystal displays are all backlight structure displays, which include multiple optical film layers such as polarizers, prism sheets, and color filters stacked in sequence. The polarizers and color filters are indispensable for realizing color display of images. An important part of. In practical applications, about 50% of the light energy will be lost when the light passes through the polarizer, and more than 40% of the light energy will be lost when it passes through the RGB color filter, which makes the light transmission rate of the display itself very low. Therefore, in order to achieve suitable bri...

Problems solved by technology

In practical applications, the reflectivity of the light will not exceed 30% after passing through the six substrate layers, which makes the reflectivity of the display device very low and cannot meet the display requirements.

In addition, even when the smectic liquid crystal in each layer structure is in a fully transparent state, the dichroic dye molecules still have a certain light absorption and present a certain color, which will further reduce the light transmittance, generally It will be much lower than 30%, and the display effect is not satisfactory

At the same time, the entire image of the display device is equivalent to being displayed on three-layer planes, and the reflection of light on different planes will produce parallax, which affects the display effect, and the liquid crystal molecules in the three-layer structure must be driven every time it is displayed. Therefore, the peripheral driving circuit of the display device is quite complicated, and the lightness of the entire display device is affected.

[0005] In addition, due to the limitation of the backlight installed on the traditional liquid crystal display and the limitation of the reflector installed on the existing smectic liquid crystal display device which can display images in color, they can only display images on one side
