Problems solved by technology
When the screen is switched, for example, when changing from a high refresh rate to a low refresh rate or from a low refresh rate to a high refresh rate, there will be a brightness difference between different refresh rates, resulting in screen flickering, and the thin film transistor unit is There is sensitivity to light, the greater the light intensity, the greater the brightness difference

The invention relates to a liquid crystal display panel and a display device. The display device comprises the liquid crystal display panel. The liquid crystal display panel comprises a backlight module, a color film substrate, a liquid crystal layer and an array substrate which are sequentially stacked from bottom to top. A black matrix of the color film substrate is used for shielding light which is emitted by the backlight module and can irradiate a thin film transistor unit. The black matrix on the color film substrate is used for shading, so that light emitted by the backlight module is prevented from irradiating the thin film transistor unit on the array substrate, the brightness difference and the sensitivity of the thin film transistor unit to light are reduced, and the variable-frequency display image quality can be improved; and a corresponding value of supplementary voltage is further increased according to different refresh rates, the voltage drop caused by electric leakageof the liquid crystal display panel during variable-frequency display is compensated, and the same brightness under different refresh rates is realized, so that the picture flicker is prevented during picture switching.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a display device. Background technique [0002] Such as figure 1 As shown, it is a structural schematic diagram of an existing liquid crystal display panel. The liquid crystal display panel 90 includes a backlight module 91, an array substrate 92, a liquid crystal layer 93, and a color filter substrate 94 in order from bottom to top. One side of the substrate 94 is bound with a flexible circuit board 95 for providing voltage to the array substrate 92 and the color filter substrate 94 to drive the liquid crystal deflection of the liquid crystal layer 93 to realize image display. [0003] Such as Figure 2A , Figure 2B As shown, when the liquid crystal display panel displays with variable frequency (variable refresh rate), after the thin-film transistor unit in the array substrate is turned off, there is a leakage phenomenon due to the semico...
