Display Timing Control for Readable Code Switching Screens

The patent applies dynamics by making the display switching speed variable rather than fixed. The control unit dynamically adjusts the display duration of each screen based on whether it contains a code element. When a code is present, the display remains static for a longer period to enable successful scanning and reading, while non-code displays can switch more rapidly. This dynamic adjustment resolves the contradiction between efficient information transmission and code readability.

The patent applies local quality by differentiating the display characteristics based on the content type. Code-containing displays receive special treatment with extended static display periods and enhanced visibility, while non-code displays maintain rapid switching. This localized quality adjustment ensures that the critical code elements are always readable while maintaining overall information transmission efficiency.

The patent applies partial action by extending the display duration only for screens containing code elements, rather than uniformly extending all displays. This selective approach ensures that code readability is improved only where necessary, while non-code information continues to be transmitted at the original rapid pace, thus minimizing the impact on overall information transmission efficiency.
