Abstract

The invention provides a display panel and a control method thereof, and the method comprises the steps: obtaining a first gray-scale value of a first position and a second gray-scale value of a second position in a same frame, and transmitting a first data voltage of the first position and a second data voltage of the second position through a same data line; obtaining a gray-scale threshold value, and determining a gray-scale difference value according to the first gray-scale value and the second gray-scale value, wherein when the absolute value of the gray scale difference value is greater than a gray scale threshold value, a first voltage range is acquired; and determining a first voltage value corresponding to the first data voltage and a second voltage value corresponding to the second data voltage according to the first voltage range, the first gray scale value and the second gray scale value. According to the invention, the two voltage values corresponding to the two positions with the large gray scale difference value can be determined according to the first voltage range obtained after judgment, and therefore the crosstalk phenomenon in a display picture is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to the manufacture of display devices, in particular to a display panel and a control method thereof. Background technique [0002] LCD (Liquid Crystal Display, liquid crystal display) has the advantages of long life, easy colorization, and not easy to burn the screen. [0003] Among them, there will be multiple capacitors between the multiple data lines in the LCD and the common electrode plate through coupling. Since the voltage difference between the two ends of the capacitor cannot change suddenly in a short time, when the voltage signal transmitted in the data line changes greatly, As a result, the voltage of the common electrode plate also changes abruptly, thereby forming crosstalk at a corresponding position in the display screen and degrading the quality of the LCD display screen. [0004] Therefore, in the current LCD, there is a phenomenon of display screen cros...
