Problems solved by technology

However, when the distance between the lines is too short, the testing equipment cannot accurately measure the electrical changes of the single line, so that the electrical testing of the lines of the display panel cannot be performed correctly.

Embodiment Construction

[0056] figure 1 It is a partial schematic view of the display panel and its semi-finished products according to the first embodiment of the present invention. Please refer to figure 1 Generally speaking, when manufacturing a display panel, the motherboard 1 is divided into multiple blocks for making the display panel, and each block corresponds to the substrate 10 after cutting. Each substrate 10 corresponds to a complete display panel (for the convenience of description, the display panel 100 will be described below), and after cutting (such as figure 1 The dotted line in represents the cutting line), each display panel 100 still retains the substrate 10 , that is, the substrate 10 can be the substrate of the display panel 100 . Moreover, before the display panel 100 is assembled and packaged, the display panel 100 is still in the stage of a semi-finished product (ie, it is a semi-finished product of the display panel 100 ). The above are well known to those skilled in the...

Abstract

The invention provides a display panel and a detection method therefor. The display panel comprises a first signal circuit, a second signal circuit and a plurality of resistance elements, wherein the first signal circuit comprises a plurality of first signal lines arranged in parallel along a first direction, with the first signal lines electrically connected with one another, the second signal circuit comprises a plurality of second signal lines arranged in parallel along the first direction, with the second signal lines are arranged parallel with and alternate with the first signal lines, each signal line is connected with at least one first resistance element, a space between the first signal lines and the second signal lines is smaller than 60 micrometer, and a resistance difference between the first signal lines and the second signal lines ranges from 30 ohm to 30,000 ohm.

Description

technical field [0001] The invention relates to a display panel and a detection method thereof, in particular to a display panel whose adjacent signal lines are adjusted to have different electrical characteristics and a detection method of a semi-finished product thereof. Background technique [0002] Because the flat panel display has the advantages of being thin, light, small, and does not take up space, the flat panel display has become a mainstream product in the current market. The flat panel display is configured with a display panel for displaying images through the display panel. Generally speaking, during the manufacturing process of the display panel and before leaving the factory, electrical testing and lighting testing are performed on the display panel to ensure the quality of the display panel. Wherein, the electrical testing can be carried out after the circuit of the display panel is completed, so as to confirm whether the formed circuit is flawed or not. ...
