Hello, friends!
We work with a system based on the DPLC230 + TPS99000 chip, We measured the length of time that LED_SEL (3:0) signals were active in one frame time. Specifically, the dynamic range of the signal LED_SEL driving R, G, and B is equal to the ratio of the total drive time and the shortest drive duration allocated to R, G, and B respectively by the signal LED_SEL in one frame time。So, we get the following measurement results:
The dynamic range is 256.52 for red light and 263.78 for green light,but it's 128.07 for blue light. Generally, the dynamic range of R、G、B should not be the same? What is the reason for this phenomenon?Thank you!
