Problems solved by technology

Therefore, when the TCP pin 140 is bonded to the ITO pin 111 of the glass substrate 110, at the blocking area 139, the copper wire pattern layer 122 of the TCP tape and reel carrier package pin 140 will be separated from the overflow to the insulation. The metal residue 1329 on the surface of the layer 135 contacts, causing an electrical short circuit and impairing the quality of the entire display assembly. The impact cannot be underestimated.

Embodiment Construction

[0018] Please refer to FIG. 2 , which is a cross-sectional view of a display unit according to a preferred embodiment of the present invention. In FIG. 2 , the display assembly 200 includes a glass substrate 210 , a tape carrier package (TCP) 220 and a protective insulating layer 290 . The display component 200 is, for example, a liquid crystal display component, and the glass substrate 210 is, for example, a glass substrate of a TFT substrate.

[0019] The glass substrate 210 has a display area 260, a plurality of indium tin oxide (Indium Tin Oxide, ITO) pins 211, and is equipped with a plurality of shorting bars, such as wires 231a, 231b, and 231c, and a plurality of wires. , only the wire 232b is used for illustration in FIG. 2 .

[0020] An insulating layer (Passivation Layer, PL) 233 is covered on the wires 231a, 231b and 231c. The wiring 232 b is located on the insulating layer 233 , and the wiring 232 b is covered with an insulating layer 235 which is also on the insu...

Abstract

The display assembly includes one glass substrate, one tape carrier package (TCP) and one protective insulating layer. The glass substrate is provided with a display area, lines and wires connected to one test unit. During test, the display area is connected via lines and wires for the test unit to test on the display area. After test, the wires are blocked and the glass substrate is not connected to the test unit. Only after the blocking area is formed, the protective insulating layer is formed on the glass substrate to cover the blocking area, and TCP is connected electrically with the glass substrate. The present invention can prevent TCP from contacting residual metal in the blocking area and prevent short circuit, and this raises the quality of the display.

Description

(1) Technical field [0001] The invention relates to a display unit, and more particularly to a display unit having a protective insulating layer to avoid short circuits. (2) Background technology [0002] For the general liquid crystal display (liquid crystal display, LCD) process, the general pre-process method is to perform a function test on the TFT substrate after the polarizer is attached to the thin film transistor (Thin Film Transistor, TFT) substrate. When the tested TFT substrate is defective, it must be discarded, which often causes the attached polarizer to be discarded, resulting in waste of the polarizer. In order to avoid waste of raw materials and save manufacturing costs, after the first cutting of the TFT substrate and before attaching the polarizer, a 2G3D or 2G2D pre-test (pre-test) is performed on the TFT substrate to screen out defective products first. TFT substrate. [0003] Please refer to FIG. 1A and FIG. 1B at the same time. FIG. 1A is a partial ...
