If the yellow ambient light is necessary, using blue as the TFT-LCD background color of will provide better performance. According to the results, white light, normal ambient illumination and a background with primal colors seemed to be the optimal conditions. The backgrounds with primary colors had better mean correct answers than the gray background. VISUAL: Q: Are Hantronix LCDs sunlight readable A: Yes, Hantronix high bright, high contrast TFT’s are sunlight readable. OV7670 is the most affordable camera module that can be used with the Arduino, so you can use this in a lot of projects.

Mean text comprehension performance were higher under 500 lux and blue background. In this article, I will show you how to display the stream from an OV7670 camera module onto a 1.8-inch TFT LCD screen using Arduino. Results of Experiment 2 indicated that the illumination intensity and background color had significant effects on mean text comprehension performance for reading comprehension.

In general, the backgrounds with primary colors had better mean character identification performance than the middle-point colors and gray. Mean character identification performance was best under white light, 500 lux, and blue background.

Results of Experiment 1 indicated that all the three independent variables had significant effects on mean percentage of character identification. This study investigated the effects of ambient illumination conditions (illumination color and illumination intensity) and background color on visual performance (character identification and reading comprehension) with TFT-LCD screens.
