Abstract

The invention discloses a driving circuit and a display device. The driving circuit comprises a time schedule controller and a first level converter, wherein the first level converter generates a plurality of first clock signals through a first time schedule control signal and a second time schedule control signal output by the time schedule controller in combination with a time schedule logic relationship. Compared with the prior art, the first clock signals can be generated through fewer time sequence control signals, so that the number of the time sequence control signals sent by the time sequence controller is reduced, the wiring space is saved, and the occupied number of I / O ports of the time sequence controller and the level converter is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a driving circuit and a display device. Background technique [0002] In the driving circuit of the display device, GOA (Gate Driver on Array, array substrate row driving technology) is being widely used. GOA is a technology that directly fabricates the gate drive circuit on the array substrate, which has the advantages of narrow frame, low cost, and high yield. [0003] The driving of GOA requires a level shifter. The level shifter amplifies the timing control signal sent by the front-end timing controller to the positive and negative voltages that can turn the transistors in the GOA circuit on and off, so as to control the GOA circuit to open step by step. However, in the existing display devices, the timing controller sends out many timing control signals, which occupy a large wiring space; at the same time, the I / O ports of the timing controller and the level shif...
