Problems solved by technology
[0005] However, due to the doubling of the number of scan lines, the scan time allocated to the scan lines is reduced, thereby reducing the charging time of each pixel.
Since the data line has a certain impedance, the voltage signal will cause delay and distortion of the waveform during transmission, and cause differences in the charging rate of each pixel, resulting in bright and dark lines

The present invention provides a display device and a driving method thereof. The display device includes a plurality of data lines and a plurality of scan lines. A plurality of data lines intersect with the plurality of scan lines to form a plurality of pixels. The driving method includes the steps of: calculating a plurality of gray scale differences between two adjacent frames of a plurality ofdata voltages input to a plurality of pixels through each data line; calculating a plurality of gray scale differences between adjacent two frames by a plurality of data lines A total gray level difference between two adjacent frames of a plurality of data voltages input to the plurality of pixels; determining a driving mode corresponding to the total gray level difference; and driving the display apparatus according to the driving mode. The present invention can effectively reduce the power consumption of the display device without degrading the efficiency of the display device.
Description
technical field [0001] The present invention relates to a display device and its driving method, and in particular to a display device and its driving method for selecting different driving modes in response to different loads. Background technique [0002] With the rapid development of display devices, people will use large and small display devices, such as mobile phones and computers, on any occasion and at any time. While using the display device, each time the screen of the display device changes, it will cause different power consumption, and the power consumption also directly affects people's concerns about using the display device. [0003] Various components of a display device are often integrated through precise design to ensure better display effect while reducing power consumption. A large number of scan driving circuits and data driving circuits need to be provided in the display device to drive each pixel in the display device. Compared with the data drivin...
