Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Splicing seams between liquid crystal display devices disrupt the continuity and integrity of the picture, affecting the visual effect of the splicing screen.
Innovation Solution
A display device design incorporating a flexible circuit board with light-emitting diodes, where the board is detachably connected to a printed circuit board, allowing the light-emitting diodes to be positioned along the edge of the liquid crystal display screen to block seams and facilitate easy replacement or repair without disassembling the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple liquid crystal display devices are spliced together to form a large display area, then the display area is increased, but splicing seams are formed between adjacent devices which disrupt picture continuity and integrity
Solution Approach 1:
A lamp board is introduced as an intermediary component between adjacent liquid crystal display devices. The lamp board includes a flexible circuit board with light-emitting diodes that are disposed along the edge of the front surface of the display screen. This intermediary structure effectively masks the splicing seams between adjacent display devices, blocking them from view and thereby eliminating the harmful visual effect while preserving the increased display area.
2Device complexity
If the lamp board is integrated with the liquid crystal display screen, then the structure is more compact, but the lamp board cannot be easily replaced or repaired without disassembling the screen
Solution Approach 1:
The lamp board is designed as a separate, detachable module from the liquid crystal display screen. The flexible circuit board includes a first part disposed on the edge of the front surface and a second part extending outside the screen to a rear surface, where it can be detachably connected to a printed circuit board. This segmentation allows the lamp board to be independently replaced or repaired without disassembling the display screen, thereby improving ease of repair while maintaining a relatively integrated appearance during normal operation.
3Ease of repair
If the flexible circuit board extends outside the liquid crystal display screen to the rear surface, then the lamp board can be detachably connected for easy maintenance, but the circuit board structure becomes more complex
Solution Approach 1:
A flexible circuit board is used instead of a rigid circuit board structure. The flexible circuit board includes a first part disposed on the edge of the front surface of the liquid crystal display screen and a second part extending outside the screen to the rear surface. This flexibility allows the circuit board to be detachably connected to a printed circuit board on the rear surface, enabling easy maintenance while managing the structural complexity through the use of flexible materials that can accommodate the extended configuration.

AI summary
The present disclosure provides a display device and a splicing screen, relating to the field of display equipment. The display device includes a liquid crystal display screen, a lamp board, and a printed circuit board. The lamp board includes a flexible circuit board and a plurality of light-emitting diodes. The flexible circuit board includes a first part and a second part connected to each other. The light-emitting diodes are disposed on the first part, and the first part is disposed on an edge of a front surface of the liquid crystal display screen. The second part extends outside of the liquid crystal display screen to a rear surface of the liquid crystal display screen and is detachably plugged into the printed circuit board disposed on the rear surface. Since the first part is disposed on the edge of the front surface of the liquid crystal display, a picture displayed on the light-emitting diodes can block an edge region of the liquid crystal display screen. Therefore, when a plurality of display devices is spliced into a splicing screen, split seams can be reduced or even eliminated, thereby improving visual effect.
