An illumination brightness and color control system and method therefor are provided. A broadband light source monitor senses and samples a point light source for a luminous intensity signal value. Then, a corrected current value is computed based on a difference between the luminous intensity signal value and a target brightness/color value, and a driving current generated by a light source driver to drive the point light source is adjusted according to the corrected current value.

Illumination brightness and color control system and method therefor

A full-color organic electroluminescence (OEL) display panel includes a substrate and a plurality of full-color OEL pixel devices in a matrix form as a display frame. Each of the pixel devices is composed of a plurality of sub-pixel regions, corresponding to R, G or B colors. Each of the specific color sub-pixel regions in the pixel device abuts the same specific color sub-pixel region of the adjacent pixel device thereof to form a double-sized emission area. With this arrangement of sub-pixel regions, it is easier to manufacture (a) high-resolution full-color OLED panels by a metal-mask alignment process, and (b) high-resolution full-color PLED panels by an ink-jet printing process.

Full-color organic electroluminescence display panel having sub pixel regions

An illumination brightness and color control system for adjusting the illumination of a plurality of point light sources and method therefor are provided, implemented in a time division manner. A single photosensor senses and samples a point light source for the luminous intensity signal value. Then, the luminous intensity signal value at each wavelength and a target brightness/color value are compute to acquire a corrected current value, and the corrected current value is fed back to a light source driver. Therefore, the brightness/color value of the point light sources is adjusted to be in a steady state.

A self-charging organic electroluminescent display is disclosed. A solar cell and an organic electroluminescent device are installed on a same substrate or different substrates. Using the photoelectric conversion property of the solar cell, the solar energy is converted into electrical energy and stored in a battery. Therefore, the electrical energy converted from the solar energy can be provided for the organic electroluminescent device to emit light, forming a self-charging organic electroluminescent display module.
