  • Patent number: 9024980
    Abstract: A method for converting input RGB data signals to output RGBW data signals for use in an OLED display is disclosed. In the OLED display, each pixel has three color sub-pixels in RGB and one W sub-pixel. Input RGB data signals in signal space are normalized and converted into input data in luminance space. A baseline adjustment level is determined from the input data and is used to compute baseline adjusted data in luminance space. After being converted from luminance space into signal space, baseline adjusted data in RGBW are represented by N binary bits presented to the four sub-pixels. To suit the color characteristics of the display, color-temperature correction to the output signals is also carried out. In luminance space, the maximum color-temperature corrected output data fall within the range of 0.4/k and 0.5/k, with k being the ratio of W sub-pixel area to the color sub-pixel area.

  • Patent number: 5544967
    Abstract: A pen including an upper barrel to hold a battery source, a lower barrel, a tip socket connected to the lower barrel at one end to hold a light source, a propelling mechanism fixedly mounted inside the lower barrel and turned by it to move a writing element in and out of the tip socket, a screw cap mounted on the upper barrel at the top and moved to control the electric circuit between the light source and the battery set, wherein a flashing circuit is mounted inside the upper barrel and connected to the light source by the writing element when the writing element is received inside the lower barrel, causing the light source to flash; a telescopic metal tube is connected to the inside of the lower barrel to hold the tip socket and moved to extend the tip socket away from the lower barrel when the pen is to be used as a pointer.
