但是那个滤色器吸收了一些亮度。

It's way more efficient than the color filter method, and so there's no need for a white subpixel to help bring brightness back up.

它比滤色器方法更有效，因此不需要白色子像素来帮助恢复亮度。

At the base level, LG Display's OLED panels mixed blue and yellow to make white subpixels that then go through a color filter to create red, green and blue.

在底层，LG Display 的 OLED 面板将蓝色和黄色混合形成白色子像素，然后通过滤色器产生红色、绿色和蓝色。
