Abstract: A touch sensing apparatus utilizes the characteristics of orthogonal vectors is disclosed. A random spread spectrum (RSS) signal or a periodic wave is used to modulate a driving signal so as to driving a row of a sensing array, and the RSS signal or periodic wave is also use to extract touch information of a node from a sensing signal measured from a column of the sensing array. The node is an intersection of the driven row and the measured column. When different RSS signals and/or periodic waves are used to drive multiple rows simultaneously, multipoint touching information can be obtained from the same sensing signal at the same time by respectively using the RSS signals and/or periodic waves to extract touching information of multiple points which are the intersections of the driven rows and the measured column.

Abstract: A touch sensing device and method for detecting a touch event of a sensing array are disclosed. In the present invention, a random duration square wave signal is used to modulate a current or voltage signal so as to generate a modulated driving signal for driving a row of the sensing array. The random duration square wave signal has cycles of different durations so that the modulated driving signal also has the same cycles with the different durations. A sensing signal is measured from a column, for example, of the sensing array. Touching information is extracted by using the random duration square wave signal to demodulate the sensing signal.

Abstract: An image compression device includes a floating-point texture-loading unit, a shader, a RGB to YCrCb compressor, and a parameter adjusting unit. The floating-point texture-loading unit receives raw image data that includes N number of RGB pixels. The shader receives the raw image data and shades the N number of RGB pixels. The RGB to YCrCb compressor receives the shaded image data and calculates the brightness/chroma value of each of the RGB pixels, wherein the chroma value of the RGB pixel having the smallest brightness value among all the RGB pixels is selected as a common chroma value for all the RGB pixels. The parameter adjusting unit receives and adjusts N number of brightness values of the RGB pixels and the common chroma value and stores them in a form of compressed image data into a memory.
