Problems solved by technology

At present, there is no case of using a bare LCD screen. Compared with an LCD screen with a metal frame, the use of a bare LCD screen reduces the overall thickness and has a significant advantage; however, a bare LCD screen is easily damaged during an electrostatic test Electrostatic damage, so it is necessary to increase the anti-static interference structure

Embodiment Construction

[0013] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0014] to combine figure 1 — image 3 As shown, the metal cover 9 of the display screen, the bare liquid crystal screen 1, the liquid crystal support 2 and the instrument PCB board 10 are arranged sequentially from top to bottom.

[0015] to combine image 3 — Figure 5 As shown, the bare liquid crystal screen 1 is located directly above the liquid crystal support 2, both of which are rectangular. An "L"-shaped corner frame 3 is respectively arranged at the left front corner and the left rear corner of the top of the liquid crystal support 2, and a "one"-shaped corner frame is respectively arranged at the right front corner and the right rear corner of the top of the liquid crystal support 2 8. The bare liquid crystal display 1 is just placed in the space enclosed by the four corner frames, and is limited to the left by the vertical part of the "L" sh...

Abstract

The invention discloses an exposed liquid crystal screen installing structure. The exposed liquid crystal screen installing structure comprises a display screen metal cover, an exposed liquid crystal screen, a liquid crystal support and an instrument PCB which are sequentially arranged from top to bottom, the exposed liquid crystal screen is rightly arranged in the space defined by four corner frames, left limiting is performed through the vertical portions of the L-shaped corner frames, an installing-positioning column is arranged on each corner frame of the liquid crystal support, and the four installing-positioning columns are arranged in a rectangular mode. Two hooks extending from bottom to top and facing the inner side are arranged on the left side and the right side of the liquid crystal support respectively, the four hooks are arranged in a rectangular mode, hook heads of the hooks are pressed above the exposed liquid crystal screen, and the rear end of the display screen metal cover extends vertically and downwards to extend the instrument PCB and then is inwards and horizontally bent in part and is attached to the bottom of the instrument PCB together. The exposed liquid crystal screen installing structure is specially used for exposed liquid crystal screen installation, the overall size is decreased, and static electricity of the liquid crystal screen is conducted to the instrument PCB to avoid that the exposed liquid crystal screen is damaged by the static electricity during static electricity testing.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an installation structure of a bare liquid crystal screen. Background technique [0002] Existing liquid crystal screens for automobile instruments all have their own metal frames, which wrap the upper and lower sides of the liquid crystal screen, and a metal elastic support is arranged on the instrument PCB to guide the static electricity of the liquid crystal screen. At present, there is no case of using a bare LCD screen. Compared with an LCD screen with a metal frame, the use of a bare LCD screen reduces the overall thickness and has a significant advantage; however, a bare LCD screen is easily damaged during an electrostatic test Static damage, so it is necessary to increase the anti-static structure. Contents of the invention [0003] The present invention aims to provide an installation structure specially used for bare liquid crystal screens, and prevent the bare li...
