Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual laser sintering is used to physically connect disconnected signal lines to reserved signal lines, then the display can display normally, but the repair process is cumbersome, costly, and inefficient requiring factory return
Solution Approach 1:
The patent applies preliminary action by pre-configuring repair signal lines and connection switches during the manufacturing process, before any disconnection occurs. The repair signal lines are reserved alongside normal signal lines, and connection switches are pre-installed to enable automatic switching between normal and repair modes. This allows the display to be repaired in-situ without factory return, resolving the contradiction between maintaining display functionality and improving repair efficiency
Solution Approach 2:
The patent implements self-service through an automatic repair mechanism that detects signal line disconnections and activates corresponding connection switches to route signals through repair signal lines. The system automatically identifies which connection switch to activate based on the disconnection location, eliminating the need for manual laser sintering operations and enabling the display to repair itself without external intervention
2Reliability
If manual laser sintering is used to repair disconnected signal lines, then the display can display normally, but the process requires factory return and manual operations
Solution Approach 1:
The patent implements self-service through an automatic repair mechanism that detects signal line disconnections and activates corresponding connection switches to route signals through repair signal lines. The system automatically identifies which connection switch to activate based on the disconnection location, eliminating the need for manual laser sintering operations and enabling the display to repair itself without external intervention
Solution Approach 2:
The patent uses connection switches as intermediaries to bridge the gap between disconnected signal lines and repair signal lines. These switches act as mediators that automatically redirect signal flow when a disconnection is detected, replacing the need for manual physical connection operations and simplifying the repair process to an automatic electrical switching operation
3Ease of repair
If manual laser sintering is used to physically connect signal lines, then disconnected lines can be repaired, but the cost is high and accuracy may be affected
Solution Approach 1:
The patent replaces the mechanical laser sintering process with an electrical switching mechanism. Instead of using laser energy to physically fuse conductive materials, the system uses connection switches to electrically connect repair signal lines to disconnected signal lines. This substitution eliminates the precision requirements and costs associated with manual laser operations while maintaining reliable electrical connections
4Ease of repair
If factory return is required for signal line repair, then proper repair can be performed, but time and costs increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring repair signal lines and connection switches during the manufacturing process, before any disconnection occurs. The repair signal lines are reserved alongside normal signal lines, and connection switches are pre-installed to enable automatic switching between normal and repair modes. This allows the display to be repaired in-situ without factory return, resolving the contradiction between maintaining display functionality and improving repair efficiency

AI summary
Disclosed are a display apparatus, a drive chip, and an electronic device. A plurality of connection switches (12) in a connection switch group in a signal line repair module (10) of the display apparatus are disposed in a one-to-one correspondence with a plurality of signal lines (DL). Input ends of the connection switches (12) in the same connection switch group are electrically connected to corresponding signal lines (DL), and output ends thereof are electrically connected to one corresponding repair line (DUM). The plurality of connection switches (12) in each connection switch group are disposed in a one-to-one correspondence with a plurality of stages of first shift units (11). When determining that a disconnected signal line (DL) exists, a drive chip (30) sends a control signal to the signal line repair module (10), so that a shift output end (OUT) of a first shift unit (11) corresponding to the disconnected signal line (DL) outputs an enable signal, so as to control a corresponding connection switch (12) in a connection switch group to be turned on, to enable the disconnected signal line (DL) to be electrically connected to a repair line (DUM). The display apparatus may repair a disconnected signal line without being returned to a factory and a manual operation.
