A display device consisting of a multi-color light emitting layer and method of depositing the multi-color light emitting layer over a glass substrate are provided. The display device consists of multiple light emitting materials deposited over a glass substrate in coplanar relationship to each other. The method provides depositing one light emitting polymer material over one portion of the glass substrate and depositing other light emitting polymer materials over other portions of the glass substrate, such that the multiple light emitting polymer materials are deposited in a coplanar relationship to each other. The light emitting polymer materials are deposited using flexographic mats, the relief portion of which have patterns corresponding to the respective portions of the glass substrate being covered by the light emitting polymer materials being deposited.

A method of modifying the polarization state of light exiting a Liquid Crystal Display that is effected without altering the optical image of the display comprises reducing the select voltage to the LCD cell to less than the saturation select voltage. In one embodiment of an apparatus incorporating features of the present invention, a color LCD display is constructed using two or more LCD cells that are aligned to produce an optimum image through the display optics. One or more of the LCD cells are then driven to the dark state at a select voltage that is less than the saturation select voltage for that cell. By operating the LCD cell at less than the saturation select voltage, the polarization state of the light exiting a dark selected pixel compensates for the misalignment between the saturation voltage polarization axis of the display and the system polarization axis of the optics. Accordingly, the selected pixel appears darker than would the same pixel driven at the saturation voltage. By operating the LCD cell at less than the saturation select voltage, higher contrast ratios and improved color saturation is achieved without sacrificing image quality.
