Abstract

The invention provides a display device. A transistor is arranged in a display panel; therefore, when the display panel is short-circuited, the time sequence controller can transmit a signal to the level shifter to cut off the transistor, so that the display panel cannot receive a scanning signal transmitted by the GOA circuit, the display panel enters an over-current protection state, and GOA wiring in the display panel is protected from being burnt out under the short-circuit condition.

Description

technical field [0001] The present application relates to the field of display, in particular to a display device. Background technique [0002] In order to protect the existing GOA (Gate Driver on Array, integrated gate drive circuit) panel from burning out in the case of a short circuit, the OCP (over current protection, over-current protection) is generally implemented through the peripheral drive circuit. )Protect. [0003] In the existing GOA panel, when the level conversion module of the peripheral drive circuit board detects a large current, the level conversion module outputs a feedback level to the analog circuit module of the peripheral drive circuit board, so that the analog circuit module no longer outputs analog Voltage to the display panel, so that the display panel enters the OCP protection state. It can be seen from this that the structure of the OCP protection circuit of the existing GOA panel is relatively cumbersome and the effect is not good. Contents...
