Fully transparent liquid crystal display module

Abstract

The invention discloses a fully transparent liquid crystal display module which comprises a backlight unit and a fully transparent liquid crystal display arranged above the backlight unit, wherein the fully transparent liquid crystal display also comprises at least an external light source acquisition unit; the external light source acquisition unit is used for acquiring external light rays to the backlight unit. Through adding the external light source acquisition unit on the fully transparent liquid crystal display module, the light source of the fully transparent liquid crystal display module is not only provided by the prior backlight unit, but also provided by the external light source acquisition unit; the luminance of the fully transparent liquid crystal display module can be changed along with the change of the external light source; the fully transparent liquid crystal display module also can realize normal display under the outdoor strong light and has high contrast ratio and good display effect; and the light source of the liquid crystal display module can be better supplied and strengthened, so that the backlight power consumption of the prior backlight unit is saved, thereby achieving the higher luminance. Meanwhile, the fully transparent liquid crystal display module also keeps the characteristics of high opening ratio and high color saturation of the prior fully transparent liquid crystal display module.

Description

【Technical field】 [0001] The invention belongs to the field of liquid crystal display, in particular to a fully transparent liquid crystal display module. 【Background technique】 [0002] With the development of modern consumer digital technology and the increase of demand, Liquid Crystal Display (LCD for short) is widely used in consumer digital products. Liquid crystal display is favored by people for its small size, thin shape, light weight, low power consumption, low heat generation, low working voltage, no radiation, and accurate image restoration. At the same time, people have higher and higher requirements for its display effect. . [0003] Liquid Crystal Module (LCM for short) includes a liquid crystal display and a backlight unit that provides a light source for the liquid crystal display. Existing liquid crystal display modules can be divided into transmissive and semi-reflective transflective from the display. (Transflective) and reflective (Reflective). Among th...
