First I develop the lighting for the LCD display. The display is an ST7735 chipset with a resolution of 128*160 pixels.
I use a 3W led as the light source. It should be bright enough for my project and will not generate too much heat during continuous operation.
I also need to make a pre-lens out of resin to focus the light onto the display.

Here is the first test setup.
