Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a COG liquid crystal screen. Background Art

[0002] The current COG display needs to be bound to the driver IC. Since the driver IC is a light-sensitive device, a black light-shielding paper is usually attached to the back of the display to prevent light from shining from the back to the bump surface of the driver IC, thereby affecting performance. The bump surface refers to the side of the driver IC with metal bumps.

[0003] However, the method of attaching black shading paper will add an extra step in the production process, which will seriously affect the production efficiency. At the same time, the attachment of the black shading paper also requires alignment, which is a complicated process. Utility Model Content

[0007] The invention also includes a second glass substrate, wherein the second glass substrate is disposed on the first side surface of the first glass substrate.

[0008] The polarization assembly further includes a second polarizer, and the second polarizer is disposed on the second glass substrate away from the first side surface of the first glass substrate.

[0009] The size of the second polarizer is the same as that of the first polarizer.

[0010] It also includes protective glue, which is arranged on the driver IC.

[0011] It also includes a driving pin, and the driving pin is arranged on the first glass substrate.

[0012] It also includes a metal terminal, which is arranged on the driving pin.

[0013] The shielding portion has a rectangular cross-sectional structure.

[0014] The length of the shielding portion ranges from 1 / 2 to 2 / 3 of the length of the first polarizer.

[0015] The first glass substrate and the second glass substrate are parallel to each other.

[0016] Compared with the prior art, the utility model has at least the following advantages:

[0017] The present application extends the first polarizer to form a shielding portion, and uses the polarizer's light-reflecting and opaque property to replace the traditional method of using black shading paper to shield the bump surface of the driver IC, thereby not only improving production efficiency but also eliminating the complicated alignment process.
