Problems solved by technology

[0003] However, when the display device 1 is assembling or pulling and soldering components, the insulation film 30 is often missed or stuck in a bad position due to personnel negligence, so as to reduce the production yield.
Since the color of the insulating film 30 is similar to that of the circuit board 20, checking and confirming the adhesion of the insulating film 30 by human eyes will not only consume manpower and production time, but also may cause leakage.

Abstract

The invention provides a display device and a detection method for the display device. The display device includes a display module, a circuit board and an insulation film. The circuit board is disposed on the display module. The circuit board is provided with a grounding mark and a plurality of signal gaskets, wherein the grounding mark can surround an element zone and the signal gaskets are arranged in the element zone. The insulation film is covered on the grounding marks and the element zone.

Description

technical field [0001] The invention relates to a display device and a detection method thereof, in particular to a display device and a detection method capable of improving yield. Background technique [0002] see figure 1 , the known display device 1 has a display module 10 , a circuit board 20 and an insulating film 30 , wherein the circuit board 20 is disposed on the display module 10 , and the insulating film 30 is attached to the circuit board 20 . In order to prevent the signal pads 22 of the circuit board 20 from being short-circuited or electrostatically affected by other components during assembly or use, the insulating film 30 is attached to the signal pads 22 . [0003] However, when the display device 1 is assembled or soldered, the insulating film 30 is often missed or attached in a bad position due to personnel negligence, which reduces the production yield. Since the color of the insulating film 30 is similar to that of the circuit board 20 , checking and ...
