The Optrex DMF-50316 surface luminance is 130 candelas. Brightness is uniform because the backlight tube runs the entire length of the module. The light does not have to travel far from tube-to-screen, and there is significantly less diffusion than with LCDs having a small tube design. Overall dimensions are 180 mm × 70 mm × 14 mm. The viewing area measures 132 mm × 39 mm with a dot pitch of 0.53 × 0.53. The LCD also features an onboard controller IC, the TC963C controller, and 64K SRAM. A user's manual is available at the company's website.
