Embodiment Construction
[0028] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.
[0029] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected ...

Abstract
The invention relates to a display panel and a manufacturing method of the display panel. The display panel comprises a substrate and a plurality of measuring pads arranged on the substrate at intervals. Each measuring pad comprises an electrical area and an insulating area. The insulating area in each measuring pad is adjacent to the electrical area in the adjacent measuring pad, and is located between the two electrical areas. According to the invention, under the premise that the size of a probe is not changed, through arrangement of the insulating area, an avoiding area around the probe isformed, so the center of the probe is electrically connected with the electrical area of one measuring pad, and the periphery of the probe is connected with the insulating area of the adjacent measuring pad. Thus, the risk of a measurement failure caused by the electrical connection between the probe and the two measuring pads due to too dense arrangement of the measuring pads is avoided.
Description
technical field [0001] The invention relates to the technical field of display panel testing, in particular to a display panel and a manufacturing method of the display panel. Background technique [0002] During the production process of display panels (such as TFT-LCD panels), the TFT glass will be electrically inspected after completing all the processes at the array end. At this time, a probe signal loading device is needed to load signals to the measurement pads of the TFT glass and measure The pads use conductive wires to transmit signals, and the display panel can achieve the required color display by measuring the different signals obtained by the pads, so as to detect whether the display panel is defective. However, for small-sized, high-pixel panels, the measurement electrical area of the display panel is limited, and the arrangement of the measurement pads will be too dense. There is a risk of measurement failure if there are more than two measurement pads. If...
