SOURCE plate protecting cover and design method thereof, liquid crystal module and liquid crystal television

Abstract

The invention discloses a SOURCE plate protecting cover and a design method thereof, a liquid crystal module and a liquid crystal television. The liquid crystal module comprises a liquid crystal screen, a SOURCE plate, a bendable COF (chip on flex) line, a front framework and a SOURCE plate protecting cover, wherein the SOURCE plate and the liquid crystal screen are connected by the bendable COF line, the front framework is arranged at one side of the SOURCE plate, the SOURCE plate protecting cover is arranged above the SOURCE plate, the end part of the SOURCE plate protecting cover is bent to the SOURCE plate at the bending part of the COF line, and the bending angle is an inclined angle. The SOURCE plate protecting cover has the advantage that the space of the end part of the SOURCE plate at the bending part of the COF line is increased, and the gap between the end part of the SOURCE plate protecting cover and the front framework is reduced, so as to resist the possible damage on the COF line when the front framework is deformed, and well protect the COF line and the liquid crystal screen.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a SOURCE board protective cover and a design method thereof, a liquid crystal module and a liquid crystal television. Background technique [0002] At present, the LCD screen of the LCD module in the LCD TV is composed of a glass area, a SOURCE board (source driver board), and several COF lines (soft accessory circuit boards with chips attached) connecting the two. figure 1 is a top view of an existing single liquid crystal display, figure 2 is a cross-sectional side view of an existing liquid crystal module; figure 2 Among them, 21 is the protective cover of the SOURCE board, 22 is the front frame, 23 is the COF line, 24 is the SOURCE board, 25 is the glass area of ​​the liquid crystal screen, and the end of the protective cover of the SOURCE board has a right angle bending angle 210. see figure 1 and figure 2 , For the situation that the speaker in the LCD...

AI Technical Summary

Problems solved by technology

The protective cover formed by sheet metal stamping can effectively resist impact and extrusion, but the bending angle of this form of protective cover at the COF line of the LCD screen is generally a right angle, because the edge of the sheet metal will be deformed after stamping. Relatively sharp, it is easy to scratch the COF line when the LCD module is assembled or the COF line is bulging

In addition, when the front frame is squeezed, there is also the danger of oppression and damage to the COF line. If a COF line damages the entire LCD screen, it will not work properly.
