A New Optimized Gray Scale Control Method Based on Parallel Sub-frame and Bit Scan
Gray scale is one of the most important parameters to judge the display quality of Flat Panel Display (FPD). The widely used technique to control the FPDs gray scales nowadays is Pulse Width Modulation (PWM) and Sub-frame, which orderly scan display pixels by row, column and frame to obtain the gray scale display. It results in lots of time waste in the scanning process. This paper dissertates the construction of the space-time mapping topology architecture that cast grayscale matrix in space to a gray-scale scanning space-time plane. By the construction, it presents a new optimized gray scale control method which based on scanning by bit and parallel Sub-frame transmission. The method proposed in this paper aims at the time redundancy which commonly exists in the FPD imaging process, and break through the traditional imaging method by decomposing one plane into multi-planes. Based on this novel idea and the construction of the scanning space-time mapping topology architecture, a Box Insert Model is proposed in the paper. The theoretic model have significant meaning to solve the bottle problem of transfer speed from memory space to display plane, and provide a new way of enhancing scan efficiency and reducing refresh frequency.
