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

The invention relates to a method for driving a liquid crystal panel, which is suitable for driving a semi-transmissive and semi-reflective liquid crystal panel. The transflective liquid crystal panel has a single cavity pitch, and has a plurality of transflective pixel electrodes arranged in an array to drive a liquid crystal layer. The liquid crystal panel driving method includes dividing a frame time into a first sub-frame time and a second sub-frame time, and setting a first driving voltage and a second driving voltage. A backlight is provided. In the first sub-frame time, a first driving voltage is applied to the transflective pixel electrode, and the backlight source is turned on. In the second sub-frame time, a second driving voltage is applied to the transflective pixel electrode, and the backlight source is turned off.
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...
