Title: DISPLAY DEVICE AND METHOD FOR ELIMINATING DISPLAY SCREEN SPLIT OF DISPLAY DEVICE
Abstract:
A display device, comprising: a display panel assembly (100) and a signal controller (200). The display panel assembly (100) comprises: multiple pixels arranged in an array, at least two data drivers (120a, 120b), and multiple data lines connected to each data driver (120a, 120b). The pixels are connected to the corresponding data lines. The signal controller (200) is connected to the data drivers (120a, 120b). The signal controller (200) is used for obtaining, when the multiple pixels display a monochrome picture of the same gray scale, voltage data of two data lines respectively connected to two adjacent data drivers (120a, 120b), and adjusting gamma codes in the two adjacent data drivers (120a, 120b) according to the obtained voltage data, until data voltages outputted by the two adjacent data drivers (120a, 120b) to the data lines respectively connected thereto are the same. Display screen split in a high-resolution display device caused by the use of the at least two data drivers (120a, 120b) is eliminated, so that the display effect of the display device is improved.
