Innovation Solution
A driving package with an integrated display is developed, comprising a display part and a driving part in a single package, where the display part includes light emitting devices forming pixels, and the driving part includes a semiconductor chip with driver IC circuits, allowing seamless connection without bezels for easy screen enlargement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple unit display panels or backlight panels are connected to enlarge the screen, then the screen size is increased, but the wiring and structure become complicated due to difficulty in connecting driver ICs and MCUs
Solution Approach 1:
The patent combines the display part and driving part into a single integrated package. The driving part includes a semiconductor chip with driver IC circuits that are directly integrated with the display part containing light emitting devices. This merging eliminates the need for separate connections between driver ICs and multiple display panels, thereby reducing wiring complexity and structural complications while enabling easy enlargement of screens by connecting multiple integrated packages.
2Adaptability or versatility
If separate driver ICs and MCUs are connected to drive pixels in multiple unit display panels, then the display functionality is extended, but the connectivity is limited and the structure is complicated
Solution Approach 1:
The driving part is integrated within the same package as the display part, with the semiconductor chip containing driver IC circuits directly connected to the light emitting devices. This integration improves connectivity reliability by eliminating external connection points and reducing the number of connection interfaces, while still allowing extension of display functionality by connecting multiple integrated packages in series or parallel configurations.
3Area of stationary object
If conventional unit panel connecting techniques are used to enlarge screens, then the screen area is increased, but the manufacturing time and cost increase due to complex assembly processes
Solution Approach 1:
By integrating the display part and driving part into a single package, the patent reduces the number of assembly steps required. Instead of separately assembling display panels and driver ICs, the integrated package is manufactured as a unified component, thereby reducing manufacturing time and cost while enabling easy enlargement of screens by simply connecting multiple integrated packages together.
