Embodiment 1

[0023] Such as Figure 4 As shown, the liquid crystal module 10 described in this embodiment includes, from the outside to the inside, a hybrid front frame 100 and a plastic frame 200 that are mutually matched and fixed, and are clamped between the hybrid front frame 100 and the plastic frame 200. Between the liquid crystal panel 300 and the backplane 400, wherein the backplane 400 is made of conductive materials such as metal.

[0024] Such as Figure 2 to Figure 5 As shown, the hybrid front frame 100 is composed of metal parts 110 and plastic parts 120 connected, wherein the hybrid front frame 100 only adopts at least one metal part 110 at the position where the chip-on-chip film 310 is arranged, and the other front frames 100 are correspondingly The plastic part 120 made of plastic material is adopted. The COF 310 is arranged along the upper side or the left side of the liquid crystal panel 300. Specifically, four source COFs (SoucreCOF) and two gate COFs (GateCOF) are re...

Embodiment 2

[0029] Such as Figure 6 As shown, the difference between it and Embodiment 1 is that compared with the hybrid front frame in Embodiment 1 which is a split front frame, the hybrid front frame 100 in this embodiment is an integrated front frame. After the metal part 110 is produced, it is placed in a plastic model, and the plastic injection molding process is adopted to make the metal part 110 and the plastic part 120 form an integrated front frame. Post-assembly process improves production efficiency.

[0030] To sum up, according to the actual application, a hybrid front frame design is adopted, and the components arranged in different positions are made of metal or plastic materials to form the hybrid front frame, that is, the front frame at the corresponding part of at least one COF Use metal parts, and then electrically connect the metal parts and the backplane of conductive material through conductive parts, so as to effectively discharge the static electricity of the li...

Abstract

The invention aims at providing a plastic and metal mixed front frame which has low cost and light weight and has an anti-static function and a liquid crystal module. The plastic and metal mixed front frame is composed of at least one metal part made of metal materials and at least one plastic part made of plastic materials in connection mode. The metal part is applied to the front frame on the corresponding portion of at least one chip on film, the metal part and a rear panel of an electric conduction material are electrically connected through an electric conduction part, and accordingly electrostatic discharge of a liquid crystal display panel is effectively achieved. The at least one plastic part is applied to other portions of the front frame. Therefore, weight of the front frame is effectively reduced, the purpose of reducing weight of the whole liquid crystal product is achieved, and liquid crystal production weight reduction is achieved. Simultaneously, use amount of metal materials used for producing the mixed front frame can be greatly reduced so that production cost of the front frame is greatly reduced and the technical problems of high production cost and large weight of the liquid crystal module are solved.

Description

technical field [0001] The invention belongs to the field of liquid crystal displays, in particular to a plastic and metal mixed front frame and a liquid crystal module. Background technique [0002] The liquid crystal module includes a backlight module and a liquid crystal panel, and the backlight module and the liquid crystal panel are fixed through a front frame. The chip on film (Chip On Film, COF for short) method is used to install the driving integrated circuit (IC) on the flexible circuit board, the IC chip is packaged in the COF, and the IC chip is connected to the pin of the COF. Such as figure 1 As shown, taking a liquid crystal module including four source COFs (SoucreCOF) and two gate COFs (GateCOF) as an example, the source COF and the gate COF are usually located on the upper side and the left side of the liquid crystal panel 30 respectively. . [0003] In the existing design, in order to discharge the static electricity on the liquid crystal panel 30 , an ...
