AI Technical Summary
After a long time of use, the conductive point may be poorly contacted, resulting in weak or disconnection of the COMMENT signal driving ability, which will make the display pattern fade.
By setting different driving pins between the first glass plate and the second glass plate and electrically connecting them to the metal terminals, instead of setting conductive points in the liquid crystal box, the COMMENT and SEGMENT traces are ensured to be respectively turned on.
This solution effectively maintains the driving capability of the COMMENT signal, avoids the problem of poor contact with the conductive point, and ensures the normal display of the display pattern.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of display screens, in particular to a segment code LCD display structure. Background Art
[0002] At present, the display screens of segment code LCDs are all connected by metal clips to the display pins, and the display pins are the pins of SEGMENT and COMMENT routing. The SEGMENT routing pins and the COMMENT routing pins are located on different glass substrates. When both are powered on, an electric field is formed to flip the liquid crystal in the LCD box and display the pattern.
[0003] In the related art, since the SEGMENT and COMMENT traces share a metal clip, and the metal clip is located on the glass substrate where the SEGMENT traces are located, it is necessary to set a conductive point in the liquid crystal box formed by the two layers of glass substrates to conduct the glass substrate where the COMMENT traces are located, thereby conducting the COMMENT traces. However, after a long period of testing, this method will cause poor contact at the conductive point, and then fail to conduct the two layers of glass substrates, resulting in a weakened or disconnected driving capability of the COMMENT signal, and ultimately causing the display pattern to fade. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a segment code LCD display structure, which can replace the method of setting conductive dots and maintain the driving ability of the COMMENT signal, thereby ensuring the normal display of the display pattern.

[0013] The second routing is a SEGMENT routing.
[0014] It also includes a first polarizer, which is arranged on the first glass plate.
[0015] It also includes a second polarizer, which is arranged on the second glass plate.
[0016] Compared with the prior art, the utility model has at least the following advantages:
[0017] In the present application, the first driving pin is set on the first glass plate, and the second driving pin is set on the second glass plate. The first driving pin is electrically connected to the first metal terminal, and the second driving pin is electrically connected to the second metal terminal. The first routing line is the COMMENT routing line, which is connected to the first driving pin, and the second routing line is the SEGMENT routing line, which is connected to the second driving pin.
