DLED liquid crystal display television backplane without hardware forming mould and preparation method thereof

Abstract

The invention discloses a liquid crystal display television backplane without hardware forming mould and preparation method thereof. The backplane comprises four aluminum profiles, four die-casting angle aluminum profiles and a piece of plane steel plate. The four aluminum profiles orderly head-to-tail form a rectangle shape in the vertical; The four die-casting angle aluminum profiles are shaped L, which each inserts in die cavities of the two adjacent aluminum profiles and locks by a screw between the die-casting angle aluminum profile and the corresponding aluminum profile, and then the two adjacent aluminum profiles are fixed, so as to form a rectangular aluminum frame; The plane steel plate covers the four aluminum profiles which form the rectangular aluminum frame, and are fixed by screw locking, a cavity is enclosed by the four aluminum profiles and the plane steel plate to contain the electronic device corresponding to the DLED liquid crystal display television. There is no need to use hardware forming moulds to make the backplane. The technology is characterized by low in mould costs, simple to process, stable in processed product size, controllable in distortion and stable and reliable in quality.

Description

technical field [0001] The invention relates to the technical field of liquid crystal televisions, in particular to a metal-free forming mold DLED liquid crystal television backplane and a manufacturing method thereof. Background technique [0002] DLED LCD TV is a kind of LCD TV, and DLED LCD TV uses direct LED. Direct-lit products evenly distribute LED lights behind the panel, so that the backlight can be evenly transmitted to the entire screen, and the details of the picture are more delicate and realistic. The prior art LCD TV usually includes a front frame and a back plate. The liquid crystal display screen is usually mounted on the front frame, and the back plate is mounted on the rear of the front frame. Because the inner cavity surrounded by the front frame and the back plate Therefore, the backplane is usually made into a cavity type. In order to form the cavity, in the prior art, a series of metal forming molds (blanking, drawing and Stretching, bending, punching...

AI Technical Summary

Problems solved by technology

The prior art LCD TV usually includes a front frame and a back plate. The liquid crystal display screen is usually mounted on the front frame, and the back plate is mounted on the rear of the front frame. Because the inner cavity surrounded by the front frame and the back plate Therefore, the backplane is usually made into a cavity type. In order to form the cavity, in the prior art, a series of metal forming molds (blanking, drawing and Stretching, bending, punching dies, etc.) to make the cavity of the back panel, because the size of the DLED LCD TV is getting bigger and bigger, and the back panel is usually integral, for the back panel of the large-size DLED LCD TV Processing requires the development of metal forming molds with a cost of more than one million, which has become the disadvantage of expensive molds and high development costs.

Moreover, the backplane processed by metal forming molds still has disadvantages such as weak strength, large deviation of external dimensions, and poor uniformity of dimensions.
