Problems solved by technology
However, in the double cell thick structure, the thickness of the liquid crystal layer of the reflective sub-pixel and the transmissive sub-pixel are different, the structure is relatively complex, the manufacturing process is also relatively complicated, and the response time of the reflective sub-pixel and the transmissive sub-pixel is different, and the optical path length of the transmissive area is long. , longer reaction time
At the same time, the invalid area occupies a large area, which reduces the display efficiency

Embodiment Construction
[0050] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0051] Fig. 2 and Fig. 3 show the first embodiment of the pixel unit structure of the transflective liquid crystal display provided by the present invention. In the first embodiment, the pixel unit 200 includes three transmission sub-pixels 201 , 202 and 203 for displaying a transmission image, and one reflection sub-pixel 204 for displaying a reflection image. The three transmissive sub-pixels 201 , 202 , 203 are within the area of the reflective sub-pixel 204 . A plurality of pixel units 200 are arranged to f...

The invention provides a semi-transparent semi-reflection liquid crystal display (LCD) device and a pixel unit thereof. The pixel unit comprises a first-type subpixel and at least two second-type subpixels. The first-type subpixel surrounds or partially surrounds at least two second-type subpixels. The first-type subpixel is a reflective subpixel or a transmission subpixel. The second-type subpixels are transmission subpixels or reflective subpixels. The area except at least two edges of each second-type subpixel is covered by the first-type subpixel. Due to the fact that transmission and reflection are independently controlled, the pixel unit of the semi-transparent semi-reflection LCD device is capable of better achieving matching of optical properties and simultaneously capable of achieving through a single-box thick structure. Consequently, the pixel unit is simple in structure and simplified in process, increases effective display areas, improves reflectivity and transmissivity, and also improves image contrast.
Description
technical field [0001] The invention relates to a transflective liquid crystal display, and more specifically, to a pixel structure unit in the transflective liquid crystal display. Background technique [0002] Liquid crystal display has the advantages of low voltage, low power consumption, large amount of displayed information, easy colorization, etc., and has been widely used in display devices of electronic equipment such as electronic computers, electronic notepads, mobile phones, cameras, and high-definition televisions. Different from cathode ray tube or plasma display device, it does not emit light itself, but achieves display purpose by modulating external light, that is, it relies on different reflection and transmission of external light to form different contrast to achieve display purpose. [0003] The most basic structure of a liquid crystal display device is to sandwich a liquid crystal layer between a pair of substrates, and control the molecular orientation ...
