Problems solved by technology

Because two data lines have been used to provide data signals to the reflective area and the transmissive area respectively, and then arrange shapes on the respective electrodes to form the alignment structure of liquid crystal molecules, the aperture ratio at this time will be reduced to an unacceptable range. There are major flaws in the design

[0031] figure 2 It is a schematic diagram of pixel electrodes of a wide viewing angle reflective-transmissive liquid crystal display device in the second embodiment of the present invention, wherein 201 is a reflective electrode, and 202 is a transmissive electrode. Similar to the first embodiment, one pixel includes a reflective electrode 201 and a transmissive electrode 202 , and a boundary region is formed between the reflective electrode 201 and the transmissive electrode 202 , and the size of the boundary region is the same as in the first embodiment.

[0032] The second embodiment differs from the first embodiment in that the shapes of the reflective electrode 201 and the transmissive electrode 202 are different from the shapes of the reflective electrode 103 and the transmissive electrode 102 in the first embodiment. Similarly, the reflective electrode 201 and the transmissive electrode 202 can form an alignment structure of liquid crystal molecules by forming a latera...

[0034] image 3It is a schematic diagram of a pixel electrode of a wide viewing angle reflective transmissive liquid crystal display device in the third embodiment of the present invention, wherein 301 is a reflective electrode, and 302 is a transmissive electrode. The difference between this embodiment and the first embodiment lies in that the shapes of the reflective electrode 301 and the transmissive electrode 302 are different from those of the reflective electrode 103 and the transmissive electrode 102, and the boundary region between the reflective region and the transmissive region has two " m" shape and connect with each other.

[0035] Similar to the first embodiment, different voltages are applied to the reflective electrode 301 and the transmissive electrode 302. Due to the shape of the boundary region, the orientation distribution of liquid crystal molecules can be better formed, thereby improving the viewing angle characteristics of the liquid crystal display devi...

Abstract

The invention relates to a LCD panel which comprises an upper substrate, a lower substrate, a liquid crystal layer which is arranged between the upper substrate and the lower substrate, and a drive circuit which provides drive signals for the LCD panel. Each of a plurality of pixels of the lower substrate comprises a reflection electrode and a transmission electrode, and the voltages applied to the reflection electrode and the transmission electrode are different. The structure can increase the visual angle of the LCD and ensure the opening ratio without any additional process.

Description

technical field [0001] The invention relates to a liquid crystal display panel and a liquid crystal display using the panel, in particular to a reflection-transmission liquid crystal display panel and a display with a wide viewing angle. Background technique [0002] In order to realize the color reflective transmissive liquid crystal display, it is necessary to set a reflective electrode area in the fully transparent liquid crystal display panel. Chinese Patent No. 200510125430 discloses a liquid crystal display panel provided with reflective electrode regions. Wherein, a reflective area and a transmissive area are respectively arranged on a substrate of the liquid crystal display panel, and the thickness of the liquid crystal layer in the reflective area is smaller than that in the transmissive area, and each sub-pixel is controlled by a thin film transistor (TFT, thin film transistor). , and receive input signals from the same data line, this structure can ensure that li...
