Display Panel Four-Subpixel Architecture White Light Generation

The pixel unit is divided into four sub-pixels (first, second, third, and fourth sub-pixels), each responsible for emitting light of different colors or contributing to white light generation. This segmentation allows selective activation of sub-pixels based on display requirements, enabling white image display without requiring all sub-pixels to emit simultaneously, thus reducing power consumption while maintaining brightness.

The fourth color filter portion acts as an intermediary by converting incoming light into primary colors through light conversion materials. This conversion process enables the generation of white light when the converted light is mixed with other light, allowing the display to achieve sufficient brightness without requiring all sub-pixels to emit at full intensity, thereby reducing overall power consumption.

Different sub-pixels are assigned different functions and light emission characteristics. The first, second, and third sub-pixels emit light of specific colors (red, green, blue respectively), while the fourth sub-pixel contains light conversion materials that convert light into primary colors. This local differentiation allows the display to achieve color balance through selective light emission and conversion rather than requiring all sub-pixels to operate at high brightness simultaneously, thus reducing power consumption.

The light conversion materials in the fourth color filter portion change the parameters of incoming light by converting it into primary colors. This parameter transformation enables flexible control over the intensity and color composition of light from different sub-pixels, allowing the display to achieve balanced brightness across red and green channels without requiring both to operate at maximum power levels.

The fourth sub-pixel is designed with light conversion materials that convert incoming light into primary colors, creating a localized function that complements the other sub-pixels. This local quality differentiation ensures that when the blue sub-pixel emits at high brightness, the light conversion process in the fourth sub-pixel contributes appropriate color components to maintain overall color balance, preventing color distortion while preserving sufficient overall brightness.

The fourth color filter portion incorporates composite light conversion materials that can convert light into multiple primary colors. This use of composite materials enables the fourth sub-pixel to generate a balanced spectrum of light that compensates for the dominance of blue light, ensuring that high brightness from the blue sub-pixel does not compromise the overall color balance of the displayed image.
