Problems solved by technology

With the emergence of users' requirements for light weight and ultra-thin electronic products such as mobile phones and tablet computers, TFT-LCD is also moving in the direction of light weight and ultra-thin. Among them, the thickness of TFT substrate and color filter can be as thin as 0.15mm, the thickness of the polarizer can be as thin as 0.05mm, and the backlight is very soft, so it is difficult to protect the connection terminals. During product testing, assembly, or user use, the connection terminals are easy to break when they are bumped , the line connected in the connecting terminal is easy to break, resulting in a black or blurred LCD screen

Embodiment Construction

[0019] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The "lower surface" in the present invention refers to the surface facing opposite to the light emitting direction of the thin film transistor liquid crystal display.

[0021] see figure 2 , which is a schematic cross-sectional view of a thin film transistor liquid crystal display in the first embodiment of the present invention, and other components not related to the improvement of the present invention over the prior art are not shown here. The thin film transistor liquid crystal display includes a cover plate 10, an upper polarizer 20, a first substrate 3', a second substrate 4', and an IC chip 70. The upper polarizer 20 is arranged on the lower surface of the cover plate 10, and the first substrate 3' is arranged On the lower surface of the upper polarizer 20, and one en...

Abstract

The invention discloses a thin film transistor liquid crystal display, comprising a cover plate, an upper polaroid, a first substrate, a second substrate, and an IC chip. The upper polaroid is arranged on the lower surface of the cover plate. The first substrate is arranged on the lower surface of the upper polaroid. The edge of one end of the first substrate is provided with a connection terminal. The IC chip is arranged on the first substrate close to the connection terminal. The second substrate is arranged on the lower surface of the first substrate. The thin film transistor liquid crystal display can enhance strength of the connection terminal, and prevents blank screen and broken screen caused by impacting the display.

Description

technical field [0001] The invention relates to the field of displays, in particular to a thin film transistor liquid crystal display. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) is popular because of its small size, low power consumption, and no radiation, and has become a product that dominates the market for electronic products such as mobile phones and tablet computers. Such as figure 1 As shown, the existing TFT-LCD mainly includes a cover plate 10', an upper polarizer 20', a color filter 30', a TFT substrate 40', a lower polarizer 50', an IC chip 70' and a backlight 60', Since the IC chip needs to be bound on the TFT substrate, the area of ​​the TFT substrate is larger than that of the color filter and the upper polarizer. There is a gap between the end where the IC chip is located and the cover plate, and the connection terminal is on the edge of this end. With the emergence of users' requirements for light weight and ultra-th...
