Problems solved by technology

[0003] As the frequency increases, the charging time decreases, so that the brightness of the screen is lower under the same gray scale, that is, the brightness in the game mode is smaller than the brightness in the normal mode, and then there is color difference, which reduces the display effect.

Abstract

The invention provides a driving circuit and a display device, and the driving circuit comprises a power management module which comprises a voltage control unit, the voltage control unit is providedwith a power input end and a first output end, the power input end is connected with a first voltage, and the power input end is also connected with a second output end; the second output end is connected with the first end of the first resistor, the second end of the first resistor is connected with the first output end and the first end of the second resistor, and the second end of the second resistor is grounded. The control module comprises a thin film transistor, a grid electrode of the thin film transistor is connected with a control signal, and a drain electrode of the thin film transistor is grounded; and one end of the third resistor is connected with the source electrode of the thin film transistor, and the other end of the third resistor is connected with the second end of the first resistor. According to the driving circuit and the display device, chromatic aberration can be avoided, and the display effect is improved.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a driving circuit and a display device. 【Background technique】 [0002] With the continuous development of the display screen, there are many modes of the display screen, such as game mode and normal mode. The game mode is the state where the user uses the display screen to play games. Usually, the frequency of the display screen in the game mode is different from that in the normal mode. , more frequently in game mode. [0003] As the frequency increases, the charging time decreases, so that the brightness of the screen is lower under the same gray scale, that is, the brightness in the game mode is lower than the brightness in the normal mode, resulting in chromatic aberration, which reduces the display effect. [0004] Therefore, it is necessary to provide a driving circuit and a display device to solve the problems existing in the prior art. 【Content of invention】 [00...
