Test pattern output device according to the aging mode of the display device

摘要

The test pattern output device according to the aging mode of the disclosed display device generates a test pattern required by the display device adjustment process in the production line of the display device including the cathode ray tube using the OSD RGB signal of the microcomputer and outputs it to the cathode ray tube. It's about making things happen.;The apparatus of the present invention determines whether an aging mode is set when a horizontal blanking signal is input from a flyback transformer in a power-on state, and if it is set, an OSD RGB signal for an aging mode selected by an administrator according to each process. The microcomputer outputs a test pattern by using a signal, and a signal processing unit converts the test pattern input from the microcomputer into a signal suitable for scanning the cathode ray tube and outputs it to the cathode ray tube in synchronization with the sand castle pulse.;Therefore, the present invention generates a test pattern for each set of display devices by using a microcomputer, so that the productivity of the production process line and the uniform quality of the display device can be realized, and the image quality of the display device can be stabilized. To provide an effect.
