Display Brightness Adjustment via Gamma Mapping

The patent changes the parameter representation by converting brightness values from a first bit-width format to a second bit-width format through a mapping relationship. This allows the same physical bonding points to represent more brightness levels effectively, improving precision without adding physical components.

The patent introduces a brightness value mapping module as an intermediary that converts between different brightness value representations. This mediator enables precise brightness control by mapping limited bonding point values to a broader brightness range, effectively improving precision without increasing the number of bonding points.

The patent creates a universal brightness adjustment mechanism that works across different driving chip types. The mapping relationship between first and second brightness values serves as a universal interface, allowing the same hardware bonding points to function effectively regardless of the specific driving chip manufacturer or type.

The patent implements a dynamic mapping relationship that can adapt to different driving chip characteristics. The mapping module dynamically adjusts the conversion between brightness values based on the specific chip type, enabling flexible adaptation without hardware changes and preventing bonding point waste.
