Problems solved by technology

This design structure requires signal connecting wires to connect the two parts of the circuit board, which is very inconvenient during assembly, and the production efficiency is low. Moreover, the area of ​​the printed circuit board is large, the area of ​​the shielding cover is large, and the weight is high, so it will increase the cost.

Embodiment Construction

[0014] Below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure and features provided by the present invention are described in detail as follows:

[0015] First, explain the specific structural composition and connection of the circuit chips included in the existing display, such as figure 1 As shown, the existing display product circuit is divided into two components, one part is the image processing function, including external digital and analog input and digital image signal output; the other part is the backlight drive circuit, which drives the light-emitting diode on the display panel to emit light. Provide a light source for the display panel as a backlight for the display panel. Due to the differences in the number, driving voltage and driving current of the light emitting diodes in the display panels of different manufacturers, different backlight circuit designs are required for corresponding matching. Th...

Abstract

The invention relates to a display provided with an integrated backlight drive board. In the display, a backlight driving chip and an image processing chips provided with pins respectively are arranged in the same plastic package; a metal wire is taken as an external signal transmission flat cable; inputs and outputs of the backlight driving chip and the image processing chip are connected correspondingly so as to form an integrated chip; and the integrated chip is arranged in a mainboard, connected with a digital input interface, an analogue input interface and a differential signal output interface respectively and outputs a driving signal to a backlight driving output interface so as to act on a display panel respectively. Due to the integration of the backlight driving chip and the image processing chip, the aim of saving circuit design is fulfilled and structural cost and occupied space are saved at the same time. When the integrated chip is used, the circuit design of the display can be completed by using one circuit board.

Description

technical field [0001] The invention relates to a display, in particular to a display provided with an integrated backlight driving board. Background technique [0002] At present, in the display market, more and more products use light-emitting diodes as backlights. The LED driving circuit part is designed with a professional control chip, and because it needs to correspond to various display panel specifications, it is designed as a separate circuit board for matching connection with the main circuit board. This design structure requires signal connecting wires to connect the two parts of the circuit board, which is very inconvenient during assembly, and the production efficiency is low. Moreover, the area of ​​the printed circuit board is large, the area of ​​the shielding cover is large, and the weight is high, so it will increase the cost. . [0003] In order to improve the quality of the display, make its assembly process and structural design more reasonable, contin...
