Publication number: 20150002562Abstract: A display formed with multiple pixel groups arranged in a matrix manner. Each of the pixel groups has multiple dots arranged in a predetermined identical matrix form, and has at least one first color dot, at least one second color dot and at least one third color dot. Each color dot has multiple sides adjacent to the other dots having a different color. Each color dot represents a luminance and a chrominance of corresponding full color pixel data by grouping with neighboring dots to form a plurality of overlapping full color dynamics pixel groups. The display has good spatial frequency in both X and Y axes, thus giving a higher visual perception of high resolution after performing weighted dot rendering methods, in which each dot in the display represents the luminance and chrominance of each corresponding RGB pixel by forming overlapping dynamic pixels with neighboring color dots.Type: ApplicationFiled: September 19, 2014Publication date: January 1, 2015Applicant: VP ASSETS LIMITEDInventor: Gia Chuong Phan

Patent number: 7742205Abstract: The invention relates to a color matching method for transforming a color representation of a first set of color primaries with a plurality of first signals to a second set of color primaries with a plurality of second signals in a first domain. The color matching method of the invention is to consider the characteristics of human visual perception. Since human is more sensitive to the luminous intensity than chrominance, the color matching method of the invention is considered to match the luminous intensity. The color matching method of the invention can minimize the intensity difference by utilizing the optimality of resource distribution. An additional step of smoothing the intensity difference among color primaries at the level of color primaries is appended. It enhances the visual quality especially for the images with a gradual change in numerous levels of color. Besides, when the color is outside the gamut, we keep the information of luminance by adding extra white.Type: GrantFiled: December 16, 2005Date of Patent: June 22, 2010Assignee: VP Assets Limited Registered in British Virgin IslandsInventors: Wing Keung Felix Lor, Gia Chuong Phan

Publication number: 20100123721Abstract: An image device and a data processing system. In order to process subpixel rendered RGB data such as Clear Type™ font data to be processed and put correctly on a non-RGB stripe image device such as a 2×2 matrix RGBW quad pixel image device, a matching 2×2 quad pixel image device is selected to cope with the corresponding input data triplet from the subpixel rendered RGB input data string. Since the blue dot carries the least luminance information in a white balance, Green/Blue/Red (GBR) triplet from the subpixel rendered input RGB data string is selected to match with a 2×2 matrix quadpixel image device where G and R dots of the 2×2 quad pixel have the maximum overlapping area with the corresponding G and R dots from the GBR stripe pixel data.Type: ApplicationFiled: November 18, 2008Publication date: May 20, 2010Inventors: Hon Wah WONG, Gia Chuong Phan

Patent number: 7286136Abstract: The invention relates to a display and an image data processing system. According to the arrangement of the display, two color dots having lower light intensity than the other two color dots in a white balance status are disposed on diagonal positions of the pixel group. Therefore, the display of the invention can improve the color balance in the pixel group to avoid visible dark vertical line. The image data processing system of the invention utilizes the weighted dot rendering device for pre-compressing data. We can expect that the video compressed data size or the video transmission speed is reduced accordingly to a ratio of ? (¼ in the case of RGBW of 2×2 matrix arrangement because white (W) can be regenerated from the corresponding R, G, B), thus storage memory and transmission bandwidth can be reduced considerably without degrading the visual perception of the video quality on the proprietary VP display.Type: GrantFiled: April 12, 2005Date of Patent: October 23, 2007Assignee: VP Assets LimitedInventor: Gia Chuong Phan

Patent number: 7215347Abstract: Display comprises static pixels and dots (individual element) arranged in a predetermined manner. Dynamic pixels are generated dynamically, comprising dots selected from at least two adjacent static pixels. Overlapping of dynamic pixels on the static pixels creates an enhanced resolution at the human's eyes. By adjusting the light emitting area and space of dots in a static pixel, maximum optimized brightness in a white balance equilibrium with good contrast can be obtained in finding an optimal ratio between the non light emitting area (black mask or black barrier ribs) and the light emitting area.Type: GrantFiled: January 10, 2003Date of Patent: May 8, 2007Inventor: Gia Chuong Phan

Patent number: 7091986Abstract: A display including static pixels and dots (individual element) arranged in a predetermined manner. Dynamic pixels are generated dynamically, comprising dots selected from at least two adjacent static pixels. Overlapping of dynamic pixels on the static pixels creates an enhanced resolution at the human's eyes. A weighted dot rendering method can be performed for all static and dynamic pixels of a low resolution inventive display to be displayed in an additive way with the viewing perception of an enhanced higher resolution display. By adjusting the light emitting area and space of dots in a static pixel, maximum optimized brightness in a white balance equilibrium with good contrast can be obtained in finding an optimal ratio between the non light emitting area (black mask or black barrier ribs) and the light emitting area.Type: GrantFiled: December 5, 2003Date of Patent: August 15, 2006Inventor: Gia Chuong Phan
