Embodiment Construction

[0021] The present invention is a solid-state display device with addressable light-emitting pixels. The present invention overcomes some of the problems of the prior art by using a photodetector integrated in the display to directly optically couple with the light-emitting diodes in the display. Photodetectors rely on light emitted by light emitters to generate electrical current. As a feedback mechanism, this current is used to control the current flow through the light-emitting pixel to achieve the desired light output.

[0022] The device operation process is as follows. figure 1 The display system 10 of the present invention includes a display 12 having a feedback control device 14 and a controller 16 for driving the display. As shown, the controller 16 may be an analog device, as shown, or a computer including a memory 18 and a central processing unit 20 for storing instruction sets and data. The controller writes data to particular display elements via data, address a...

Abstract

An image display, includes a substrate; a light emitter formed on the substrate; and a photosensor formed on the substrate and optically coupled directly to the light emitter.

Description

field of invention [0001] The present invention relates to a solid-state flat panel display device, in particular to such a display device with the function of optimizing the brightness of each pixel in the display by utilizing the optical feedback information of each pixel. Background of the invention [0002] As an excellent flat-panel digital display device, a solid-state organic light emitting diode (OLED) image display device has received a lot of attention. This type of display device uses an electric current to pass through a thin film of organic material to emit light. The color of emitted light and the energy conversion efficiency of current to light are determined by the composition of the organic thin film material. Also, exclusively, such display devices can be made of transparent materials that support other combinations of optical devices similar to OLED display devices. Such a system is described in US Patent 5,776,623, issued July 7, 1998 to Hung et al. ...
