Abstract: Disclosed is an illuminative module for enhancing the white balance while reducing thermal drift and color blocks. The illuminative module includes a substrate and light-emitting elements provided on the substrate to emitting light of the primary colors and a fourth color, respectively, so that the light of the primary colors is mixed with the light of the fourth color to provide white light.

Abstract: Disclosed is an LED-based streetlamp for emitting white light with easily adjustable color temperature. The LED-based streetlamp includes at least one substrate, at least three red LED packages, at least three green LED packages, at least three blue LED packages and a lamp holder. The red, green and blue LED packages are provided on the substrate. Each of the LED packages includes scattering particles for providing preferred senses of direction of light so that red, green and blue light beams cast from the red, green and blue LED packages almost completely overlap to provide a white light beam.

The area of the pads is larger than that of the electrodes.

Abstract: A method for independently adjusting six color classes with the consideration of boundary colors on a display device comprises steps of: detecting a plurality of pixels of a display device and calculate a first tint and a second tint of the pixels; defining a first pixel, the first tint and second tint of the first pixel both locating in the targeted color class; defining a second pixel, the second pixel being close to the first pixel, and the first tint and the second tint of the second pixel both locating in the neighboring of the targeted color class; defining a third pixel, said third pixel being neither the first pixel nor the second pixel; finding the first pixel and second pixel and adjusting their colors; and finding the third pixel and keeping its original color.

Abstract: The present invention relates to an improved structure of producing white light for LED, and the structure is a light emitting element composed of two chips of different color lights. The two chips are bonded with each other in series. In an epitaxial formation and manufacturing process, a first metal contact end is formed on the backside of the chip in the front and a second metal contact end is formed on the front side of the chip at the back, and the interfaces of the first and second contact ends are bonded by an eutectic solder, so that the two chips are electrically and mechanically coupled with each other. The invention simply uses a current to drive two chips to produce white light, and thus effectively saving the space of a printed circuit board, and enhancing the performance of the LED semiconductor manufacturing process.

Abstract: A method is proposed for independently adjusting single color on a display device, which contains following steps: detecting multiple pixels of a display device, and separating out the 1st and the 2nd tint of these pixels; if the 1st and the 2nd tint of a pixel are with the same color class, then adjust the color of the pixel; and if the 1st and the 2nd tint of a pixel are with the different color classes, then maintain the color of the pixel in the original status.
