IMPROVED DISPLAY DEVICE BASED ON PIXELS WITH VARIABLE CHROMATIC COORDINATES

摘要

pixel having a variable color coordinates is made of a plurality of color sub-emitter and the color filter - comprises a pixel. Luminous body are the same, and has an emission spectrum that can be modulated as a function of the supply voltage and / or current supply. Pixel control circuit for each color sub-pixel to sub-supplies the supply voltage (VR) and / or a current that depends on the color of the pixel, and that the emission spectrum is close to the transmission spectrum of the associated color filter. Control means (T3, RL) is to obtain a predetermined average luminance for a predetermined period, the sub-pixels allows to control the supply of voltage and / or duration of the applied current as a function of the color. ;
