Problems solved by technology

[0003] However, in terms of the existing panel detection method, if there is a short circuit between the adjacent data lines electrically connected to the pixels in the panel, the faulty pixels that cannot normally work according to the signal may also be damaged by the short circuit. Bright, but can not fully detect all the faulty pixels, resulting in difficult to improve the pass rate of the product

Embodiment Construction

[0058] Certain terms are used in the description and claims to refer to particular elements. Those skilled in the art should understand that manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as the way to distinguish components, but the difference in function of the components as the basis for the difference. "Include" mentioned throughout the description and claims is an open term, so it should be interpreted as "including but not limited to". In addition, "electrical connection" includes any direct and indirect electrical connection means. Therefore, if it is described in the text that the first device is electrically connected to the second device, it means that the first device can be directly connected to the second device, or indirectly connected to the second device through other devices or connection means.

[0059] The following is a detailed description according to the specific embo...

Abstract

A display panel comprises a first substrate, a plurality of pixel unit, a plurality of first signal lines, a first test line and a second test line. The first signal lines are disposed on a peripheral zone and respectively correspondingly electrically connected with the pixel units, the first signal lines comprise a plurality of first groups of sub-signal lines and a plurality of second groups of sub-signal lines in an alternating arrangement. Each group of sub-signal lines and each group of sub-signal lines are respectively provided with first sub-signal lines and second sub-signal lines, and the first sub-signal lines and the second sub-signal line are different layers. The first test line is electrically connected with the first group of sub-signal lines, and the second test line is electrically connected with the second group of sub-signal lines.

Description

technical field [0001] The invention relates to a display panel and a detection method thereof. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) and organic light emitting diode (Organic light emitting diode, OLED) display devices have been widely used in multimedia players, mobile phones, etc. On electronic products such as telephones, personal digital assistants (PDAs), computer monitors (monitors), or flat-screen TVs. In order to reduce manufacturing costs and increase the yield of panels, manufacturers usually implement inspection steps before shipment of displays, such as inspecting whether there are bright or dark spots in the pixels of the panel. [0003] However, in terms of the existing panel detection method, if there is a short circuit between the adjacent data lines electrically connected to the pixels in the panel, the faulty pixels that cannot normally work according to the signal may also be damaged by the short circuit. Bri...
