Problems solved by technology
However, the optical compensation mode can generally only assist in the front direction, and there will be light leakage at an oblique angle, so that the black state of the transmissive sub-pixel area is not black enough.
[0006] Accordingly, when the semi-reflective and semi-transmissive liquid crystal display operates in the transmissive mode display mode, it cannot present a wide viewing angle display effect, and even the display contrast effect of the traditional transmissive liquid crystal display is worse, reducing the transmissive viewing angle. Thus, it is impossible to achieve the effect of full viewing angle and wide viewing angle.

The invention discloses a dual-display mode liquid crystal display. The dual-display mode liquid crystal display is a partial penetration partial reflection type liquid crystal display. The dual-display mode liquid crystal display comprises an active matrix base plate, an upper base plate arranged above the active matrix base plate, a liquid crystal display layer clamped between the active matrix base plate and the upper base plate and a plurality of pixels formed between the active matrix base plate and the upper base plate in a matrix manner. Each pixel is provided with a penetration type sub-pixel area and a reflection type sub-pixel area. The penetration type sub-pixel area is in a first display mode, so that liquid crystal molecules distributed in the penetration type sub-pixel area are provided with first alignment structures capable of generating the wide viewing angle effect. The reflection type sub-pixel area is in a second display mode, so that liquid crystal molecules distributed in the reflection type sub-pixel area are provided with second alignment structures.
Description
technical field [0001] The invention relates to a liquid crystal display, and in particular to a dual display mode liquid crystal display. Background technique [0002] With the development of display technology, liquid crystal display devices (Liquid Crystal Display, LCD) have been widely used in various electronic products, such as notebook computers, tablet computers, mobile phones, and digital cameras. [0003] Each pixel in the existing semi-reflective and transflective liquid crystal display is usually divided into a transmissive sub-pixel area and a reflective sub-pixel area. In the transmissive sub-pixel area, the light generated by the backlight module will adjust the light phase difference through liquid crystal deflection in the transmissive sub-pixel area to control the amount of transmitted light. In the reflective sub-pixel area, external ambient light incident from the outside and reflected by the reflective sub-pixel area will adjust the light phase differen...
