Problems solved by technology

[0003] Although the AM-OLED TV's hold-type driving method makes the AM-OLED TV achieve a better static picture effect (there is no flickering phenomenon like a CRT TV), it is precisely because of the AM-OLED TV The hold-type driving mode of the TV makes the AM-OLED TV produce trailing blur when reproducing moving pictures

Embodiment Construction

[0028] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] The invention provides an OLED pixel driving circuit.

[0030] refer to image 3 , image 3 It is a schematic diagram of the circuit structure of an embodiment of the OLED pixel driving circuit of the present invention.

[0031] The OLED pixel driving circuit includes a plurality of OLED pixel units 20 arranged in a matrix, a scanning line ScanLine correspondingly connected to the OLED pixel units in each row, a data line DataLine correspondingly connected to the OLED pixel units in each column, and a data line DataLine correspondingly connected to the OLED pixel units in each row. The OLED pixel units are correspondingly connected to a power line PowerLine, and a control module 30 for controlling the light emitting time of each OLED pixel unit 20; the control module 30 is connected to each power line PowerLi...

Abstract

The invention discloses an OLED (organic LED) pixel drive circuit, comprising a plurality of OLED pixel units that are arrayed, scan lines in one-to-one correspondence with rows of the OLED pixel units, data lines in one-to-one correspondence with rows of OLED pixel units, power lines in one-to-one correspondence with columns of OLED pixel units, and a control module connected with the power lines and used for controlling lighting time of each OLED pixel unit. The invention enables a great improvement in trailing fuzziness of an AM-OLED television set while moving pictures are reproduced.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an OLED pixel driving circuit and a television. Background technique [0002] Existing AM-OLED televisions (AM-OLED, Active-matrixorganiclight-emittingdiode, active matrix organic light-emitting diode / active matrix organic light-emitting diode), the response speed of its OLED (OrganicLight-EmittingDiode, organic light-emitting diode) is very fast, Reached the microsecond level, however, the smearing and blurring phenomenon of the existing AM-OLED TV set when reproducing the moving picture still exists. The reason is that the response speed of the OLED of the AM-OLED TV is only a factor that causes the smearing and blurring phenomenon. By improving the response speed of the OLED, the overlapping problem of the image signal display is solved. Overlapping problem on the retina of the human eye (persistence of vision of the human eye, i.e. the retention characteristic); and the ...
