[0003] Therefore, the signal lines of the driving circuit part in the traditional display panel are arranged more and more densely. In this case, the particles in the display panel are easy to overlap the two signal lines, which will cause a short circuit of the display panel, and the short circuit of the display panel will cause a short circuit. Causes the display panel to heat up, causing the polarizers in the display panel to melt

Abstract

The invention discloses a level conversion circuit and a display panel. The level conversion circuit comprises: a level conversion module and a comparison module connected to the level conversion module; the level conversion module comprises a level conversion unit and a control unit connected with the level conversion unit, and the level conversion unit is used for receiving a first voltage signal and a second voltage signal and generating a level conversion result signal according to the first voltage signal and the second voltage signal; the comparison module is used for comparing the voltage corresponding to the level conversion result signal with a reference voltage when a preset time is up, generating a comparison result and feeding back the comparison result to the control unit; andthe control unit is used for controlling the level conversion unit to stop working when the received comparison result is that the voltage corresponding to the level conversion result signal is smaller than the reference voltage. The display panel can be prevented from being damaged due to short circuit.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a level conversion circuit and a display panel. 【Background technique】 [0002] In order to achieve the effect of narrow borders, the wiring area of ​​the driving circuit part of the traditional display panel is getting smaller and smaller. In addition, in order to achieve the effect of high resolution, the signal lines of the driving circuit part of the traditional display panel are increasing. [0003] Therefore, the signal lines of the driving circuit part in the traditional display panel are arranged more and more densely. In this case, the particles in the display panel are easy to overlap the two signal lines, which will cause a short circuit of the display panel, and the short circuit of the display panel will cause a short circuit. This causes the display panel to heat up, thereby causing the polarizer in the display panel to melt. [0004] Therefore, it is necessary ...
