Abstract
The present disclosure is directed to a controlled reflection readout for light emitting information displays for such apparatus as computers, compasses, watches, clocks and consoles wherein the light emitting display is not placed normal to the viewing plane and cannot be read at 90.degree. to the display. The light emitting display is inclined to the line of sight and glare shielding means extends forwardly from the top of the display to prohibit reading the display at a right angle thereto whereby reflections from the sun or lights in a room will interfere with reading through the optically transparent window in front of the light emitting display.
