In this way, if the electronic components on the circuit boards 10, 20 are to be repaired or replaced, the panel 40 must be detached from the display, and then the frame 30 must be disassembled from the panel 40, and then the circuit board 10 must be removed. , 20 are disassembled from the frame 30 to access the electronic components on the circuit boards 10, 20 for maintenance and replacement. Such disassembly operations are complicated and time-consuming
Furthermore, the positions of the power supply and signal connectors on the display are often different due to different designs. In order to configure the circuit board in an appropriate position to meet the design requirements of the connector positions, the frame 30 must be changed according to the design of different connector positions.

The invention provides a method for fixing the display and its electric circuit board. The display includes a panel, a framework located on the panel and an electric circuit board located on the framework, and a part of framework is set between the panel and the electric circuit board. The method to fix the circuit board includes the following steps: providing a framework, installing the framework on a display panel, and fixing a circuit board on the framework to locate a part of the framework between the panel and the circuit board.
Description
technical field [0001] The invention relates to a fixing method for a circuit board in a display, in particular to a fixing method for making the circuit board easy to maintain and replace. Background technique [0002] Generally speaking, in a display, especially in a liquid crystal display, a circuit board is arranged behind the panel to receive power or signal to generate an image on the panel. Figure 1a , Figure 1b It shows the fixing method of the circuit board in an existing liquid crystal display. The circuit boards 10, 20 are first fixed on the frame 30 with the side with the electronic components facing the frame 30, and then the frame 30 together with the circuit boards 10, 20 installed thereon are fixed to the panel 40 . At this time, the circuit boards 10 and 20 are interposed between the frame 30 and the panel 40 and covered by the frame 30 . In this way, if the electronic components on the circuit boards 10, 20 are to be repaired or replaced, the panel 40 m...
