Problems solved by technology

It is worth noting that by figure 2 It can be found that when the liquid crystal panel 100 is driven by the driving voltage V1, the transmittance of the liquid crystal panel 100 corresponding to the light 140 is T1, but the transmittance corresponding to the light 142 is T2, that is, T1 is only about 50 of T2. It is only about %. Under the same voltage, the display effect of the LCD panel in the reflective mode and the transmissive mode cannot be optimized at the same time.
Such a phenomenon has become one of the main reasons why it is difficult to optimize the driving of the LCD panel using the single-cavity pitch technology of the liquid crystal display

Abstract

A method for driving liquid crystal face plate includes dividing an image frame time to be the first and the second subimage frame times and setting the first and the second driving voltages, providing a back light source, exerting the first driving voltage on semipeneration pixel electrode and switching on back light source when it is on the first subimage frame time, exerting the second driving voltage on semipeneration pixel electrode and switching off back light source when it is on the second subimage frame time.

Description

technical field [0001] The invention relates to a driving method of a liquid crystal panel, in particular to a driving method of a transflective LCD panel with single cellgap with a single crystal cavity spacing. Background technique [0002] With the advancement of semiconductor technology and man-machine display technology, a multimedia lifestyle has been gradually formed. As far as the display is concerned, due to the excellent display quality and price advantage of the cathode ray tube (CRT), the cathode ray tube is widely used in the related fields of the display. However, the cathode ray tube still has many problems to be solved in terms of space utilization and energy consumption. In recent years, due to the rise of liquid crystal display technology, the thin film transistor liquid crystal display (TFT-LCD), which has the advantages of high image quality, light weight, low power consumption and low radiation, has gradually replaced the cathode ray tube and become the...
