专利汇可以提供Display device专利检索,专利查询,专利分析的服务。并且PURPOSE: To recognize sensuously the degree of display by allowing a microcomputer controlling various analog quantities of a color TV receiver such as sound volume and luminance to control the display position of a pattern or a character generated from a character display device on a cathode-ray tube.
CONSTITUTION: Circuits from a tuner 1 to a speaker 7 are the same as shown in Block diagram of a conventional color TV receiver. When either a sound-up switch 11 or a sound-down switch 12 is depressed, the microcomputer 10 supplies a required data to a D/A converter 9. Then a DC voltage value fed from the converter 9 to a low frequency amplifier circuit 6 in response to the data is decreased or increased so as to decrease or increase the sound volume. The microcomputer 10 controls the character display device comprising a row counter 13 deciding the up/down direction of the character and left/right direction display position, a column counter 15, one-shot multivibrators 16, 22, a ROM18 in which a display graphic pattern is written, and AND gates 14, 17 to change the display position of the pattern and character displayed on the cathode-ray tube.
