LCD TV and assembly method thereof

Abstract

The invention relates to a liquid crystal display television (LCD TV) and assembly method thereof. The LCD TV comprises a face shell, a back shell, a mainboard, a liquid crystal module, a power plate and an input / output device. The back shell serves as an assembly base and the liquid crystal module is assembled on the back shell; the face shell is fixed on the back shell; the liquid crystal module is arranged between the face shell and the back shell; the input / output device and the power plate are both assembled on the back shell; and the mainboard is fixedly arranged at the backside of the back shell. The LCD TV has the advantages of less components, low cost, convenient maintenance and simple process and is light and thin.

Description

Technical field [0001] The present invention relates to the technical field of liquid crystal televisions, and more specifically, to a liquid crystal television with integrated screen and machine and an assembly method thereof. Background technique [0002] The structure of traditional LCD TV figure 1 As shown, it is generally composed of the front cover 1, the LCD screen 2, the back cover 3, the base 4, the main board 5, and the hardware 6. When assembling, the assembly sequence is: first pass the LCD screen 2 through its own screw holes and The hardware 6 etc. are fixed on the face shell 1, and then the main board 5 (including the power supply board) is fixed on the LCD screen 2, and then the back cover 3 is connected and fixed on the face shell 1 through the LCD screen 2, so that the face shell 1, The LCD screen 2, the main board 5 (including the power supply board), and the back cover 3 constitute the "display screen" (including circuit boards, chips, etc.) of the TV; the bas...

AI Technical Summary

Problems solved by technology

[0004] Traditional LCD TVs have the following disadvantages: (1) A square hole must be opened in the middle of the face shell 1, and its shape is generally similar to a plane, so its strength is low; but in this structure, the face shell 1 is the installation base, which bears weight and force The largest, so its deformation is large, the gap between the panel 1 and the LCD screen 2 is not easy to control, and the requirements for design, processing, and technology are strict

(2) 80% of the weight of the LCD TV is on the LCD screen 2, so it is necessary to disperse its weight through a lot of hardware (mainboard bracket, base bracket, etc.) to strengthen the strength of the face shell 1 and the whole machine, so that the structure is complicated and the parts increase, cost increase, difficult maintenance

(3) During the use of the TV, the face shell 1 is most likely to be scratched, scratched, discolored, etc., and the user generally does not pay attention to the surface damage of the rear shell 3, and does not mind, so the face shell 1 often needs to be replaced; In the LCD TV structure, the rear case 3 needs to be removed first, and then the LCD screen 2 can be removed to replace the front case 1. Disassembly and assembly are very troublesome, and only professional maintenance personnel can do it

(4) When the circuit board or chip of the LCD TV needs to be replaced, only the entire rear case 3 can be removed for maintenance and replacement, which is a relatively large workload and quite troublesome

(5) Lightness and thinning are the development trend of LCD TVs. The weight of the LCD screen 2 is 80% of the weight of the LCD TV, and its thickness is mainly determined by the LCD module. Too many hardware parts 6 for connection or reinforcement are seriously It hinders its light and thin development

[0005] In short, because the traditional LCD TV uses the panel 1 as the assembly base, and the LCD screen 2 is an independent component, its structure is complex, there are many parts, the production is cumbersome, the cost is high, and the maintenance is difficult, and the future trend of LCD TVs is more and more The lighter and thinner the traditional LCD TV structure is, the room for improvement and development is very limited in this respect, which requires designers to propose new design ideas and solutions
