AI Technical Summary
但是，RGBW显示面板中W色组仅透光背光原生白光，无法呈现高纯度色光，导致显示面板整面显示时色域一致性差，难以满足高色域场景需求
[0014]The display panel provided by this invention improves the structure of the color filter substrate by adding a light guide structure layer on the color resist layer, enabling switchable display in high color gamut and low power consumption modes to meet the needs of different scenarios. In the first mode (high color gamut mode), the light guide structure layer changes the transmission path of the original light rays incident on the white color resist, causing the original light rays incident on the white color resist to mix with the original light rays incident on the RGB color resist before being incident on the white color resist. In other words, the light guide structure layer directs the original light rays incident on the white color resist to the RGB region, so that the light rays are modulated and mixed by the RGB color resist before being emitted. This solves the problem of uneven color gamut across the entire display panel and improves the overall color gamut consistency of the display panel, thus meeting the requirements of high color gamut scenarios. In the second mode (low power consumption mode), the light guide structure layer allows the original light rays incident on the white color resist to be emitted directly along the original transmission path. This utilizes the high transmittance of the white color resist to improve the display brightness of the display panel and reduce display power consumption, thus meeting the requirements of low power consumption scenarios.
