Abstract: PURPOSE:To improve the color reproducibility of gradations by providing a generating means for black level potentials determined correspondingly to voltage-transmissivity characteristics of the primary colors of a liquid crystal panel, and determining the black levels corresponding to the primary colors unequivocally according to the state of a single bright level adjusting means. CONSTITUTION:A black level potential generating circuit 15 for R, G, and B is equipped with a bright level adjustment terminal 19 which can be operated from the outside of the liquid crystal display device, and its output terminals 26, 27, and 28 are connected to black level setting circuits 12, 13, and 14 for R, G, and B. The output terminal of a liquid crystal panel driving interface circuit 16 is connected to the liquid crystal panel 17 including an active matrix substrate and a color filter where the primary colors are arrayed. Consequently, the voltage-transmissivity characteristics of respective picture elements of R, G, and B can be represented while being shifted approximately by a constant voltage in the voltage-axis direction. Consequently, a reproduced image with improved half-tone color reproducibility is obtained.

Title: Picture signal transmitter
Inventor: ISHIKAWA KOUJI
IPC: H04N1/19
Filed: 1978-06-06
Abstract: PURPOSE: To send out analog signals of high quality with the memory time shortened through simple circuit constitution, by reducing the capacity of an analog memory by increasing the number of blocks of analog shift registers.  
     CONSTITUTION: This device is equipped with an image sensor which converts photoelectrically picture elements for signal-scan length by high-speed clocks and two analog shift registers which are capable of memorizing one block of picture elements for single-scan length with picture elements divided into more than two blocks by using high-speed clock and of sending them out by low-speed clocks; while registers send signals for one block out by low-speed clocks, the sensor makes a scan more than once. Then, while one register is sending any block out, the other receives a block to be sent out next from the sensor, allowing alternate registers to attain transmission and reception by turns, and consequently high-speed and low- speed transmission processes are both realized, so that the simple circuit constitution will send out picture signals of high quality.
