LCD display screen mounting structure capable of compensating glass cutting tolerance

Technical Field

The utility model relates to a remote controller structure, specifically speaking are LCD display screen mounting structure that can compensate glass-cutting tolerance.

Background

The assembly of remote controller face-piece and LCD module on the market generally is conventional design, promptly: as shown in fig. 1 and 2, the face housing 1 positions the LCD module 2 by adopting a single-side clearance + top rib mode according to the external dimension of the LCD module 2, and the mounting structure thereof includes: the LCD comprises a face shell 1, an LCD module 2, a zebra stripe 3 and a PCB 4 which are sequentially arranged from front to back; the back of the face shell 1 is provided with LCD mounting grooves 1-1, the back of the LCD module 2 is provided with a plurality of LCD contacts 2-1 which are uniformly arranged at intervals along the long edge direction of the LCD module, the zebra stripes 3 are existing conductive connecting devices composed of conductive silica gel sheets 3-1 and insulating silica gel sheets 3-2 which are alternately arranged, and the front of the PCB 4 is provided with a PCB contact 4-1 corresponding to each LCD contact 2-1; the LCD module 2 is placed in an LCD mounting groove 1-1 of the face shell 1, the PCB 4 is fixed with the face shell 1 so as to tightly press the LCD module 2 on the back face of the face shell 1 through the zebra stripes 3, and each PCB contact 4-1 is electrically connected with the corresponding LCD contact 2-1 through a conductive silica gel sheet 3-1 of the zebra stripes 3. The overlapping length L1 of the LCD contact 2-1 and the corresponding PCB contact 4-1 in the long side direction of the LCD module 2 is required to be as large as possible, so that the LCD contact 2-1 can be electrically connected with the corresponding PCB contact 4-1 through a plurality of conductive silicon rubber sheets 3-1, and reliable conduction between the PCB contact 4-1 and the corresponding LCD contact 2-1 is ensured.

The existing LCD display screen mounting structure has the following defects:

due to the above-mentioned LCD screen mounting structure, in the actual production and assembly, affected by the processing tolerance (i.e. screen glass cutting tolerance) of the LCD module 2 itself, the injection molding tolerance of the panel housing 1, and the assembly tolerance, two extreme assembly modes of interference assembly and too large assembly gap are easy to occur during the assembly, resulting in: the LCD module 2 has larger deviation with the PCB 4 in the long edge direction, so that the overlapping length L1 of the LCD contact 2-1 and the corresponding PCB contact 4-1 in the long edge direction of the LCD module 2 is only one sheet or less than the thickness of one conductive silica gel sheet 3-1, the conduction reliability of the PCB contact 4-1 and the corresponding LCD contact 2-1 is extremely poor, the display performance of the LCD module 2 is influenced, the reject ratio of products is improved, and the production benefit is reduced.
