1Area of stationary object
If multiple display devices are joined to form a large-sized display apparatus, then the display size is increased, but the manufacturing cost increases and repair convenience deteriorates
Solution Approach 1:
The display system is segmented into multiple independent electronic device units, each with its own complete display function. These modular units can be independently replaced during repair, eliminating the need to disassemble the entire large display apparatus. The segmentation enables localized maintenance while preserving the overall system functionality.
2Area of stationary object
If multiple display devices are joined to form a large-sized display apparatus, then the display size is increased, but the manufacturing cost increases
Solution Approach 1:
The large display is constructed from multiple standardized modular electronic device units that can be manufactured independently using standardized processes. This segmentation allows for economies of scale in manufacturing individual units, reduces inventory complexity, and enables parallel production, thereby lowering overall manufacturing costs compared to producing a single large display.
Solution Approach 2:
Each electronic device unit is designed as a universal module that can function independently as a complete display unit. The standardized interface and modular design allow the same unit to be used in various configurations to create different sized displays, reducing the need for custom manufacturing and lowering overall production costs.
3Area of stationary object
If the display apparatus is formed by joining multiple display devices, then large-sized display is achieved, but the complexity of assembly and disassembly increases
Solution Approach 1:
The display system is divided into independently segmentable electronic device units with standardized connection interfaces. Each unit maintains complete functional independence, allowing for simplified assembly and disassembly operations. The modular segmentation reduces the complexity of handling large displays by breaking them into manageable, standardized modules.
Solution Approach 2:
The electronic device units are designed with dynamic, reversible connection mechanisms that enable easy assembly and disassembly. The flexible connection system allows units to be quickly joined or separated without complex tools or procedures, reducing the overall complexity of system configuration and maintenance operations.

AI summary
An electronic device (10A, 10B, 10C) includes a base substrate (12, 12B, 12C), a first circuit layer (14) and a plurality of light-emitting elements (16). The base substrate (12, 12B, 12C) has a first surface (S1) and a second surface (S2) opposite to each other. The first circuit layer (14) includes a first portion (14a) and a second portion (14b). The first portion (14a) is disposed on the first surface (S1) of the base substrate (12, 12B, 12C), and the second portion (14b) is disposed on the second surface (S2) of the base substrate (12, 12B, 12C). The light-emitting elements (16) are disposed on the first portion (14a) of the first circuit layer (14). At least one of the second surface (S2) of the base substrate (12, 12B, 12C) and the first portion (14a) of the first circuit layer (14) includes at least one microstructure (MS2, MS2b, MS3).
