Abstract

The invention discloses an OLED display device, comprising: pixel units distributed in an array, each row of the pixel units is connected with a light emitting control line for outputting a light emitting control signal to the pixel unit; the light emitting control signal is A periodic signal, used to control the periodic light emission of the pixel unit after the pixel unit receives the data voltage; the light emission control line connected to the pixel unit in the odd row is connected to the first clock signal terminal, and connected to the pixel unit in the even row The light-emitting control line connected to the unit is connected to the second clock signal terminal, and the light-emitting control signals output from the first clock signal terminal and the second clock signal terminal have the same frequency and a phase difference of 180 degrees. The present invention adopts two clock signals as the luminescence control signals of the OLED display device, so that the frame of the OLED display device does not need to be provided with a large luminescence control line driving circuit. Therefore, the technical solution of the present invention can effectively reduce the frame width of the OLED display device.

Description

technical field [0001] The invention relates to a display device, in particular to an OLED display device. Background technique [0002] OLED display has the advantages of small size, simple structure, self-illumination, high brightness, good picture quality, large viewing angle, low power consumption and short response time, etc., which has attracted widespread attention and is likely to become the next-generation display technology to replace liquid crystal. [0003] figure 1 Shown is a structure diagram of an existing OLED display device. Such as figure 1 As shown, the OLED display device includes pixel units 10 arranged in a matrix. Each row of pixel units 10 is connected to a first scanning line G i , a second scanning line G i-1 and a luminous control line E i (i is an integer from 1 to n); each pixel unit 10 is connected with a data line D j (j is an integer from 1 to m). figure 2 Shown is an existing pixel driving circuit. The pixel unit 10 includes the pix...
