Problems solved by technology
[0011] However, in the above transflective and transflective liquid crystal display 10, the array substrate 30 not only includes the flat layer 34, but also includes the reflective electrode layer 35 formed on the flat layer 34, and the flat layer 34 and the reflective The electrode layer 35 is formed on the array substrate 30 through an independent process, and the process is quite complicated, which affects the production efficiency of the array substrate.
At the same time, the complexity of the processing technology will inevitably lead to a decline in product yield
[0012] Secondly, there needs to be a gap between the thickness d of the liquid crystal layer 40 between the reflective electrode layer 35 and the common electrode layer 23 and the thickness D of the liquid crystal layer 40 between the planar layer 34 and the common electrode layer 23 specific relationship, and the realization of this specific relationship requires adjusting the thickness of the reflective electrode layer 35, the adjustment of the thickness of the reflective electrode layer 35 is quite difficult, and it is not easy to achieve precise adjustment, resulting in images or characters formed by reflection in the reflective area and formed by transmission in the transmissive area. poor consistency of images or text
[0013] Again, the color film layer and the pixel electrode of the color filter cover the entire pixel, and the external ambient light will be reduced by 2 / 3 when passing through the color film layer, resulting in a decrease in the light transmittance, thereby reducing the display brightness.
The pixel electrodes cover the entire pixel, so that the semi-reflective and semi-transmissive liquid crystal display 10 consumes a lot of power and has poor environmental protection performance during the process of displaying images or characters in a reflective manner and displaying images or characters in a transmissive manner.
[0014] Finally, the semi-reflective and semi-transmissive liquid crystal display 10 needs to make a reflective electrode layer 34, and the reflective electrode layer 35 is usually made of a reflective metal material, such as metal aluminum, formed by magnetron sputtering, so it needs to have a special The equipment used for metal magnetron sputtering causes the cost of the semi-reflective and semi-transmissive liquid crystal display 10 to increase; in addition, making the reflective electrode layer 34 increases the manufacturing process steps of the semi-reflective and semi-transmissive liquid crystal display 10 , which reduces production efficiency, but also increases the probability of defective products, resulting in a decline in the yield rate
[0015] In summary, there are many defects in the existing semi-reflective and semi-transmissive liquid crystal display 10, and it is very necessary to make a revolutionary change to it.

Description
technical field [0001] The invention relates to the field of flat panel display technology, in particular to a display device and a driving circuit thereof. Background technique [0002] In recent years, due to the advantages of low power consumption and small size compared with traditional CRT displays, liquid crystal display technology has developed rapidly. Liquid crystal display devices have increasingly replaced CRT displays and become mainstream display devices in people's daily life and work. [0003] Liquid crystal displays can be classified into transmissive liquid crystal displays, reflective liquid crystal displays, and semi-reflective and semi-transmissive liquid crystal displays. The transmissive liquid crystal display has a backlight, and the light emitted by the backlight passes through the liquid crystal display panel of the liquid crystal display to realize the display of information such as images or texts. The reflective liquid crystal display does not ha...
