针对现有业界高色域显示方案在显示性能、可靠性、实现复杂度和成本等无法兼容的局限,文章首次提出并验证了一种基于单晶片双波长LED芯片的创新解决方案。基于14.0WQ平台验证,单晶片双波长芯片设计、荧光粉和高色域彩色滤光匹配及电路驱动策略,可实现三百超高色域兼容覆盖率(Adobe 100%、DCI-P3 100%、sRGB 100%),同时具有色偏低、可靠性高、结构简化及成本低等优势。另外,搭配整机场景识别功能匹配最佳色域呈现能力,该显示模组支持消费者在不同的应用场景中智能切换匹配的色域。将每个色彩空间发挥到极致,真正呈现不同的图像原色,达到最佳的画面显示效果。
The innovative solution based on single-crystal dual-wavelength LED chips is proposed and validated for the first time to improve the limitations of incompatible display performance
reliability
implementation complexity
and cost of existing high color gamut display solutions in the display industry. Based on the verification of 14.0 WQ platform
the design of single chip dual wavelength chips
matching of phosphors and high color gamut color filters
and circuit driving strategies can achieve a compatibility coverage rate of three hundred high color gamut (Adobe 100%
DCI-P3 100%
sRGB 100%). At the same time
it possesses the advantages of low color shift
high reliability
simplified structure and low cost. In addition
this display module supports consumers to switch the matched color gamut in different application scenarios with the overall scene recognition function matching the best color gamut presentation capability. The scheme is proposed to maximize each color space to truly present different primary colors of the image
achieve the best visual display effect.
