【摘要】：有源矩阵有机电致发光二极管(AMOLE:Active Matrix Organic Light Emitting Diode)显示,是平板显示行业的最新技术,也是被认为能替代液晶显示器的下一代显示技术。人眼感知的亮度与实际显示亮度并非线性关系,在低亮度环境中,人眼对亮度的变化更敏感,高亮度环境则反之。Gamma参数表明了显示器亮度与输入电压的非线性关系,是显示器适应人眼感知需求的矫正参数。由于AMOLED显示器的子像素亮度比例差异大,在明亮的环境中人眼对各种色光具有不同的感受。人眼对不同色彩的感受程度也是不同的,为适应人眼的这种特性,Gamma参数调试中需要加入人眼对色彩的感知度的考虑因素。本文提出了一个方法,优化AMOLED显示器Gamma参数,平衡红绿蓝(RGB)亮度比例。本文Gamma参数的优化方法,就是以目前业界公认的Gamma 2.2调试方式为基础,加入色彩考虑因素。在白色画面亮度一定的条件下,对于RGB三色,分别调试Gamma参数,将其合成为AMOLED显示屏的最优Gamma参数。文章最后通过试验,证明了运用RGB Gamam调节后的显示器,具有更好的显示效果。
[Abstract]:Active Matrix Organic Matrix Organic Light Emitting display is the latest technology in the flat panel display industry. It is also the next-generation display technology that is considered to be an alternative to liquid crystal displays. The human eye is more sensitive to changes in luminance in low-brightness environments than in the actual brightness, which is not linearly related to the luminance of the human eye. On the contrary, the Gamma parameter indicates the nonlinear relationship between the display brightness and the input voltage, and is a correction parameter for the display to meet the needs of human perception. Because of the large difference in the ratio of the sub-pixel brightness of the AMOLED display, In a bright environment, the human eye has different feelings for various colors. The human eye also has different degrees of perception of different colors. In order to adapt to this characteristic of human eyes, we need to add the factor of human eyes' perception of color to the adjustment of Gamma parameters. This paper presents a method to optimize the Gamma parameters of AMOLED display and balance the ratio of brightness of red, green and blue. The optimization method of Gamma parameters is presented in this paper. It is based on the Gamma 2.2 debugging method recognized by the industry at present, adding color considerations. Under the condition that the brightness of the white screen is fixed, for the RGB trichrome, the Gamma parameters are debugged separately. It is synthesized into the optimal Gamma parameter of AMOLED display screen. Finally, the experiment proves that the display adjusted by RGB Gamam has better display effect.
