研究目的
To introduce methods to achieve high performance vehicle displays, focusing on high contrast of wide viewing angle, wide color gamut with high saturation, and quick response time in wide temperature range.
研究成果
The paper concludes that high contrast of wide viewing angle, wide color gamut with high saturation, and quick response time in wide temperature range can be achieved through specific improvements in POL, OA process, cell gap design, BLU film structure, LED and CF formulation, and LC material. These improvements meet the stringent requirements of OEM spec 5.0, enhancing the performance of vehicle displays.
