Display panel detection circuit and detection method thereof

Abstract

The invention discloses a a display panel detection circuit . The detection circuit comprises the display panel, a transfer flexible printed circuit board and a module lighting fixture, wherein the display panel comprises a display area and a non-display area; the non-display area is also provided with a detection signal line and a driving integrated circuit; the switching flexible printed circuit board is arranged on a pin line at the receiving end of the detection signal line and between the display panel and the module lighting fixture; the module lighting fixture is arranged at one end of the adapter flexible printed circuit board; the display panel detection circuit has the beneficial effects that firstly, the detection function module originally located in the driving integrated circuit is moved to the outside of the driving integrated circuit to be achieved, the size of the driving integrated circuit is reduced, the screen-to-body ratio is increased, and an extremely narrow frame is truly achieved; secondly, the detection method of the display panel provided by the invention is simple and convenient to operate; and finally, the periphery of the display panel is directly grounded, so that the display panel is not easily interfered by external static electricity and can play a role in electrostatic protection.

Description

technical field [0001] The present application relates to the field of display, in particular to a detection circuit of a display panel and a detection method thereof. Background technique [0002] With the rapid development of modern technology and changes in people's aesthetics, the screen-to-body ratio of mobile phone screens has increasingly become the focus of attention. At present, the screen-to-body ratio of most mainstream flagship phones on the market is 90% or even higher. The height makes the area of ​​the display area larger and larger, and the appearance of the mobile phone becomes more and more refined. [0003] At the current stage, the COG (chip on glass, chip directly bound on the glass) process is adopted for the mobile phone panel. The difficulty of increasing the screen ratio is mainly in the lower frame of the panel, because the driver integrated circuit of the panel needs to be processed through the chip coating process. In this method, the driver inte...
