Problems solved by technology
Due to the current customer demand for SDRRS (seamless display refresh rate switching, seamless display refresh rate switching), the screen frequency is 40Hz and the screen frequency is reduced to 48Hz when playing movies, based on the current AHVA (wide viewing angle, Advanced Hyper-Viewing Angle) feature , the Vcom value adjusted based on the screen frequency of 60Hz cannot be directly switched to use at the screen frequency of 48Hz / 40Hz. At this time, the corresponding optimal Vcom value is not adjusted under the screen frequency of 48 / 40Hz, so the degree of flickering is very serious. cause eye discomfort
In addition, when the frequency is reduced, the flickering degree of the screen will be different due to the difference between the positive and negative voltages and the common voltage, which will also cause discomfort to the human eye.

The invention discloses a display device and an adjusting method of the display device. The display device comprises a display panel and a public voltage generating circuit. The public voltage generating circuit comprises a storage module and a sensing module, the storage module is provided with a plurality of storage spaces, the storage spaces are used for storing a plurality of public voltages respectively, each public voltage corresponds to one corresponding different storage space, and the public voltages correspond to different frame frequency ranges respectively. The sensing module is electrically connected with the display panel and the storage module and extracts and judges frame frequency from the display panel, and when the frame frequency is located within the first frame frequency range, the first public voltage corresponding to the first frame frequency range in the public voltages is output. When the frame frequency is located within the second frame frequency range, the second public voltage corresponding to the second frame frequency range in the public voltages is output. The display device can be suitable for the display mode of multiple kinds of frame frequency to eliminate the frame flashing phenomenon.
Description
technical field [0001] The present invention relates to a display device and an adjustment method thereof, in particular to a display device and an adjustment method thereof for reducing screen flickering. Background technique [0002] A liquid crystal display (Liquid Crystal Display; LCD) is a flat panel display widely used at present, and has the advantages of light and thin appearance, power saving and low radiation. The working principle of the liquid crystal display device is to change the alignment state of the liquid crystal molecules in the liquid crystal layer by changing the voltage difference between the two ends of the liquid crystal layer, so as to change the light transmittance of the liquid crystal layer, and then cooperate with the light source provided by the backlight module to display images. [0003] See Figure 1A and Figure 1B , Figure 1A and Figure 1B Shown are schematic diagrams of the waveforms of the grayscale voltage of the display device in t...
