Touch Display Board Layout Using 3D Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited space for installing the video control board in touch displaying devices due to cable placement, which is necessary to avoid electrical interference, restricts the area available for other components.
Innovation Solution
The design incorporates a receiving area between the lower plate and the touch screen to house the video control board, touch control board, timing control board, power control board, and LED driving board, optimizing the layout to accommodate these components while minimizing cable interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If cables are placed on the touch screen to connect timing control board, signal transmitter adapter, and signal receiver adapter, then electrical connections are established, but the available area for installing the video control board becomes very limited
Solution Approach 1:
The patent transitions from a two-dimensional planar layout to a three-dimensional立体布局 by utilizing the space between the touch screen and the rear cover. Control boards are mounted on the rear cover while cables are routed through the vertical space, effectively adding a depth dimension to the layout and resolving the area conflict.
Solution Approach 2:
The patent pre-establishes cable routing paths and mounting positions during the design phase. Cables are routed through predetermined channels and fixed at specific locations before final assembly, preventing interference with control board installation areas and eliminating the need for complex post-assembly cable management.
2Reliability
If cables are routed across the touch screen area, then electrical connections are achieved, but electrical interference between cables and video control board occurs
Solution Approach 1:
The patent extracts the video control board from the touch screen area and relocates it to the rear cover. This separation removes the control board from the electromagnetic interference zone created by cables, eliminating electrical interference while maintaining reliable electrical connections through optimized cable routing to the rear cover location.
3Adaptability or versatility
If multiple control boards are installed on the touch screen, then functionality is enhanced, but the limited area prevents proper installation
Solution Approach 1:
The patent utilizes the third dimension (depth) by mounting multiple control boards on the rear cover instead of the two-dimensional touch screen surface. This立体布局 allows multiple boards to be vertically stacked or arranged in the depth space, accommodating enhanced functionality without compromising the touch screen area.

AI summary
A touch displaying device includes a housing, a displaying screen, a capacitive touch screen, a timing control board, a touch control board, a video control board, an LED driving board, a power control board, a first converting board, and a second converting board. The housing includes a first edge, a second edge, a first side edge, and a second side edge. The first converting board includes a timing signal adapter and a first electrode signal adapter. The second converting board includes a second electrode signal adapter. The first converting board, the timing control board and the touch control board are fixed in the housing and disposed adjacent to the second edge. The timing control board is disposed towards a side of the touch control board. The second adapter plate is fixed in the housing and disposed adjacent to an end of the second edge adjacent to the first side edge.
