Hello everyone, So basically a reflective LCD screen is one that has no backlight, and reflects ambient light off a type of mirror reflector, to allow the image on the LCD to be seen via reflection. An example of a reflective LCD screen is the Gameboy Advance's LCD screen. A transmissive LCD is one that has a backlight that transmits light, but does not reflect light. These are typically 99.99% of the screens out there, such as PC Monitors, Smartphone screens, etc... Now I would like to know how to turn a Transmissive LCD screen, into a Reflective screen, like the GBA screen, without the need for a backlight. The reason I ask this is because I need it for outdoor use (to be sunlight readable), and backlights can't compete with the sun, and having a strong backlight drains battery. I have done a lot of research on this, but can't wrap my head around how the GBA screen works. I have removed the backlight off my computer LCD screen, and added a reflective film beneath the rear polarizer on the LCD screen, but it obviously doesn't make it reflective. I'm obviously missing a crucial step. Is the reflective film in the GBA, 'sandwhiched' somewhere in between the actual LCD screen? Does anyone know how to make a Transmissive LCD computer monitor, into a Gameboy Advance Reflective Screen?
