Problems solved by technology

[0004] In view of this, the embodiments of the present application provide a driving circuit, a driving method, and a display device to solve the problem that if foreign matter falls into the wiring area of ​​the display panel during the traditional production process of the display panel, it will cause damage to the area. The wiring becomes a weak line, with low withstand voltage and poor overcurrent capability, and it is difficult to detect, which leads to the scrapping of the display panel and seriously increases the production cost.

Abstract

The invention is suitable for the display technology field and provides a driving circuit, a driving method and a display device. Two identical driving data under a specific gray level are outputted through a control module, one driving data is processed into two identical driving voltages by a source driving module, the two identical driving voltages are then outputted, the other driving data isprocessed into an analog voltage by a digital-to-analog conversion module, magnitudes of one driving voltage and the analog voltage are determined through a voltage comparison control module, when theone driving voltage is less than the analog voltage, the source driving module is controlled for improving a voltage value of the driving voltage, and thereby the driving voltage and overcurrent capability when a data line led out by the source driving module becomes a weak line can be improved, the pass rate of display panels can be effectively improved, and production cost is reduced.

Description

Technical field [0001] This application belongs to the field of display technology, and in particular relates to a driving circuit, a driving method and a display device. Background technique [0002] With the continuous development of display technology, display devices such as liquid crystal panels and monitors are constantly developing in the direction of lighter and thinner, larger screen, low power consumption, and low cost. Various display devices are emerging one after another, bringing great convenience to people's daily production and life. [0003] However, in the traditional display panel production process, if a foreign object falls on the wiring area of ​​the display panel, the wiring in this area will become weak, with low voltage resistance, poor overcurrent capability, and difficulty in detection. As a result, the display panel was scrapped, which seriously increased production costs. Summary of the invention [0004] In view of this, the embodiments of the present...
