TH22052A - Methods and machines for controlling matrix displays - Google Patents

Abstract

This invention solves the critical task of reducing the ratio ft / za, which ft is the clock frequency for signal processing and za represents the number of lines that have to be displayed on the matrix display. According to this invention It has been proposed to extend the period for further operation of the method. Signal processing for triggering matrix displays Into several periods of time The output video signal does not contain information. The invention can be popularly used to stimulate an LCD display (LCD).

Claims (6)

1. A method for controlling a matrix display with multiple image elements, the task of The output signal that contains the image information is swept directly from the And is accumulated using the speed that One that corresponds to the density of visual information. That was predetermined that was contained in For that work And it corresponds to the time of the active portion of the output video signal and is read out at the second rate. Which is the result of the density of visual information That will be displayed and From the time available for its display It is characterized in such a way that the density of image information to be displayed is determined by the number of elements to be controlled. Where the number of lines to be controlled of that matrix display More than the number of lines of the video signal That was sent out 2. Method according to claim 1 which has unique characteristics Is that the video signal that is sent out is inserted Complies with M standard (US standard) 3. The method according to claim 1 or 2, which is unique as follows: The number of lines of the matrix display to be controlled is 560. 4. A machine for controlling the matrix display (19) of which a memory (14,20) is provided. That is controlled by one control signal (S1) that is predetermined in such a way that the sensitive part of the The video signal is output from the image source (13) containing image information. It is collected at a rate that corresponds to the predetermined image information density. Contained in For that work And it corresponds to the timing of the transmitted video signal and is read out with a pre-defined second control signal (S2) path using the second rate. The density of the visual information that will be displayed and from the time available for The display of its results Which is characterized in such a way that Information density The image to be rendered determines the number of image elements to be controlled and the manner in which signal enhancement devices (17) will be provided. Which will process the image information that will be displayed The result is so that the number of controlled lines of the matrix display is greater than the number of signal lines. The images that are exported are 5. The device according to the four claims has unique features: The output video signal is Compliant with the M standard (U.S. standard) 6. The device according to claim 4 or 5 which has specific features, namely The number of lines of the display The matrix to be controlled is equal to 560 lines.
