Embodiment Construction

[0032] Embodiments of the present general inventive concept will now be described in detail, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like parts throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.

[0033] Figure 4 is a schematic diagram of a projection system according to an embodiment of the present general inventive concept. The projection system includes RGB LEDs 402, 404, and 406, each emitting a red (R), green (G), and blue (B) monochromatic light beam, respectively.

[0034] The RGB monochromatic light beams emitted by the RGB LEDs 402 , 404 and 406 are projected along a predetermined path by the color combiner 408 , condensed by the condensing lens 410 and then sent to the light channel 412 .

[0035] The RGB monochromatic light beams have a uniform distribution after passing through the optical channel 412 , and are tran...

Abstract

An image display method of improving brightness of an output image in an image display device using a sequential driving method and a plurality of single-color light sources are provided. The image display method includes extracting a white color component from the primary color image signals, calculating a period to display the white color component, converting the primary color image signals into shortened primary color image signals and a white color image signal based on the period to display the white color component, and driving the single-color light sources together during a period to display the white color image signal and sequentially driving the single-color light sources during a period to display the shortened primary color image signals. The brightness of output images is improved by displaying the white color image signal by simultaneously driving the single-color light sources based on a ratio of a lowest gradient to a highest gradient of the primary color signals.

Description

[0001] This application claims priority under 35 U.S.C. §119 of Korean Patent Application No. 10-2004-55077 filed in the Korean Intellectual Property Office on July 15, 2004, the entire disclosure of which is hereby incorporated by reference. technical field [0002] The present general inventive concept relates to an image display device having a sequential driving method, and more particularly, to a method of increasing brightness of an output image of an image display device using a sequential driving method and a plurality of monochromatic light sources. Background technique [0003] Color display devices, such as plasma display panels (PDPs) and microdisplay (MD) devices such as liquid crystal on silicon (LCoS) devices and digital micromirror devices (DMDs), are widely used in computer monitors and televisions. [0004] In this display device, a color image is realized by sequentially driving primary color image signals (...
