Problems solved by technology

However, in this design, since the flexible circuit board must be folded in a large area, the stiffness of the flexible circuit board must be low, and because it mainly uses gluing to combine the flexible circuit board with the frame, the adhesive must be strong enough to Prevent the flexible circuit board from rebounding and bulging, which will affect the positioning of the light-emitting diodes, and if there are many and high-density circuit components on the flexible circuit board due to the circuit design, it will inevitably cause difficulties in the work of the light-emitting diodes. Unable to accurately locate or make parts firmly, so it often affects the pass rate of subsequent quality

Abstract

The invention relates to a display device, including a frame, a display panel and a flexible printed circuit board, in which the flexible printed circuit board includes a main circuit region for driving display panel and a lightsource setting region for setting luminescent component, and said light source setting region is a cantilever extended from main circuit region. The above-mentioned display panel is placed on the frame, and the main circuit region of the above-mentioned flexible printed circuit board is directly connected with display panel, at the same time, the light source setting region is placed between display panel and frame in reflexed mode.

Description

technical field [0001] The invention relates to a display device, in particular to a display device utilizing a flexible circuit board of a display panel combined with a light-emitting component. Background technique [0002] figure 1 It is a schematic diagram of an existing display device. The display panel flexible circuit board (LCD FPC) 110 and the light-emitting diode flexible circuit board 120 connected to the display device 100 and the display panel 130 were originally separated in the display device 100, and then connected by a bonding pad 140 or by using A device (not shown in the figure) combines two flexible circuit boards, but this design must use two flexible circuit boards, and requires two additional flexible circuit board assembly processes and pressure welding operations, resulting in increased costs, and Bonding quality also affects the overall electrical performance. [0003] figure 2 It is a schematic diagram of the back of another existing display d...
