Problems solved by technology
In actual production, no matter how high the accuracy of the machine is, there may still be some display panels with low alignment accuracy, resulting in low penetration of these display panels
According to the existing production efficiency requirements, after cutting into display panels, each display panel is directly assembled with the backlight module, and it is difficult to place each display panel on the automatic optical inspection machine one by one to measure the transmittance. As a result, the brightness of the finished display module does not meet the specifications after the display panel is combined with the backlight module to form the finished display module.

The invention discloses a display panel and a display module. The display panel comprises an array substrate and a color-film substrate which are arranged oppositely, wherein the array substrate is provided with a first testing pad, a second testing pad, a first conductive portion, a first connecting pad and a first comb-like electrode, the first comb-like electrode is provided with multiple second connecting pads arranged in the first direction and is electrically connected with the first testing pad, and the first testing pad is electrically connected with the second testing pad. The color-film substrate is provided with a third connecting pad and a fourth connecting pad, wherein the third connecting pad is electrically connected with the first connecting pad, and the fourth connecting pad is electrically connected with one of the multiple second connecting pads. When the display panel is used, a resistance value between the first testing pad and the second testing pad is measured and is recorded as a first resistance value. According to the first resistance value, offset distances of the array substrate and the color-film substrate in the first direction are determined. The penetration rate of the display panel can be simply and conveniently determined, and the final yield of the display module can be also improved.
Description
technical field [0001] The present invention relates to a display panel and a display module, in particular to a display panel and a display module that can conveniently confirm its own penetration rate. Background technique [0002] In the prior art, when manufacturing a display panel, a first alignment mark is set on the array substrate motherboard, and a second alignment mark is correspondingly set on the color filter substrate motherboard. Search (Automated Optical Inspection, AOI) machine to monitor the alignment accuracy of the first alignment mark and the second alignment mark, to ensure that the alignment of the two motherboards is within the specification range. After box alignment, the motherboard is cut into multiple display panels. In actual production, no matter how high the precision of the machine is, there may still be some display panels with low alignment accuracy, resulting in low penetration rates of these display panels. According to the existing produ...
