High integration network television receiver

Abstract

The invention discloses a high integration network television receiver which comprises a back board, a luminous source fixed on the front surface of the back board, and a cavity arranged on the back board, wherein an opening of the cavity faces the front surface of the back board, and electronic components with a mainboard function and a constant current function are arranged in the cavity. A signal processing function of a mainboard and a constant current function of a drive board are integrated on the back board, while the luminous source is directly mounted on the back board. On the premise of satisfying use, a series of spare parts such as a back cover, the mainboard, a power supply board, a constant current board, a heat sink strip, heat conduction glue, a lamp bar line, a lamp bar substrate and a lamp bar socket of the existing television set can be removed, and integrated arrangement is achieved in deed. The cost is saved, at the same time, an assembly technology is simplified and quick, an overall appearance of a product is thinned, the product has excellent heat dissipation performance, and the safety and reliability of the product are improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a highly integrated network television receiver. Background technique [0002] In the prior art, inside the liquid crystal module, the LED light and the light bar socket are generally welded on the MCPCB, which is called a light bar, and then the light bar is attached to the heat-conducting adhesive and adhered to the heat-dissipating aluminum bar. Use screws to strengthen the fixation between the light strip and the heat dissipation aluminum strip, and then fix the heat dissipation aluminum strip to the back panel of the LCD module for heat dissipation, and its heat dissipation performance is poor; the light strip socket needs to be connected to the light strip wire Connect with external LED constant current driver. [0003] In addition, the back panel of the liquid crystal module needs to be equipped with a power supply board, a constant current board, and a main board fo...
