Abstract

The present invention provides a driving method of a display device and the display device. The driving method comprises the steps of sensing the threshold voltages of the driving transistors of a plurality of pixel units, and calculating the external compensation values of the display data signals according to the threshold voltages of the driving transistors of the plurality of pixel units; internally compensating the threshold voltages of the driving transistors via a pixel drive circuit; superposing the external compensation values and the display data signals, wherein the superposed datasignals are inputted to the pixel drive circuit to drive a light-emitting element to emit light. The driving method of the display device and the display device of the present invention can improve acompensation effect, thereby improving the uniformity of the display brightness of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a driving method of a display device and a display device. Background technique [0002] Compared with the liquid crystal display device in the conventional technology, the organic light emitting diode (Organic Light Emitting Diode, OLED) display device has the characteristics of fast response speed, excellent color purity and brightness, high contrast ratio, and wide viewing angle. [0003] Generally, OLED display devices can be classified into passive matrix OLED (Passive Matrix OLED, PMOLED) display devices and active matrix OLED (Active Matrix OLED, AMOLED) display devices according to their driving methods. [0004] The structure and driving method of the PMOLED display device are relatively simple, which makes the PMOLED display device easy to manufacture, but the resolution and size of the PMOLED are limited. Therefore, PMOLED display devices are generally relat...
