Problems solved by technology

When performing detection, it is necessary to use detection circuits that match the size of the panel 22a and panel 22b respectively, and perform detection in sections. Replacing the detection circuit will further increase the detection time
If there are several panels of different sizes on the substrate, it is necessary to have a variety of detection circuits of different sizes correspondingly, which will also increase the detection cost

Embodiment Construction

[0029] image 3 It is a flow chart of the liquid crystal display panel detection method according to the present invention. Firstly, a substrate is provided (step 302). Next, a plurality of panels are formed on a substrate such as a glass substrate, each panel has a plurality of first wires and second wires, and the first wires and the second wires are perpendicular to each other and form electrical connections (step 304 ). Then, using the same detection circuit as the sum of all panel sizes, these panels are simultaneously detected for defects (step 306).

[0030] Please refer to Figure 4 , which is a configuration diagram of a liquid crystal display panel according to a preferred embodiment of the present invention. According to the inspection method of the liquid crystal display panel of the present invention, firstly, four panels of equal size are formed on the glass substrate 40, which are respectively 42a, 42b, 42c and 42d. The panels 42a, 42b, 42c and 42d respectiv...

Abstract

A testing method for liquid crystal display panel: provides a base board, forms several panels on the base board, every panel with several first leads and second leads; the first lead and the second lead are vertical and forms electric connection; testing the base board whether or not with objection.

Description

technical field [0001] The present invention relates to a detection method of a liquid crystal display panel, and more particularly to a detection method of a liquid crystal display panel with an improved detection method. Background technique [0002] In the manufacturing process of liquid crystal display panels, multiple panels are usually formed on a large substrate at the same time. Once the panels are formed, each panel is tested individually to see if the manufactured panel is functioning properly. When the inspection is complete, it is cut into individual panels. figure 1 Shown is a prior art arrangement of multiple panels formed on a large glass substrate. There are four panels 12 of equal size on the glass substrate 10, each panel 12 has a plurality of vertical source lines 14, and a plurality of horizontal gate lines 16, and the intersection points of these source lines 14 and gate lines 16 , the pixel array of the liquid crystal display panel 12 is formed.
