Patent JP-H0364896-A (JP)
Title: Discharge lamp lighting device
Inventor: SAITO MAKOTO
IPC: H05B41/42
Filed: 1989-07-31
Abstract: PURPOSE:To enhance luminous efficiency by interposing a DC-DC converter between a full wave rectifier and an inverter to gradually adjust light dependently on addition of the output of the DC-DC converter into the output of the full wave rectifier. CONSTITUTION:A DC-DC converter 20 is inoperative in a light adjustment mode when a switch 2 is in a position (j), and only an output of a full wave rectifier 4 is applied to an inverter 6. Accordingly, a lamp 7 is extinguished when the output voltage of the inverter 6 is decreased lower than a specific voltage while the lamp 7 is lit with an increase of the voltage, and as a result, the luminous efficiency of the lamp 10 is low due to the repetitive switching operation. The DC-DC converter 20 is operative in a full lighting mode when the switch is in a position (k). A dc voltage of the output of the full wave rectifier 4 added into the output of the DC-DC converter 20 is supplied into the inverter 6 so that the input voltage of the inverter 6 is smoothed, thereby preventing the output voltage of the inverter 6 from being decreased lower than the specific voltage. Therefore, the re-lighting of the lamp can be prevented so as to enhance the luminous efficiency.

IPC: G02F1/1368
Filed: 1985-09-10
Abstract: PURPOSE:To simplify a peripheral circuit by driving signal electrodes corresponding to respective color picture elements by mutually independent driving circuits. CONSTITUTION:A row driver 6 select scanning electrodes successively. Column drivers 7-9 are independent of one another by colors and data on the colors are transferred directly to the respective drivers 7-9 in synchronism with the clock from a clock generator 10 and displayed on a liquid crystal panel 1. Further, the column drivers are independewnt of one another by signal electordes of red, green, and blue, so voltages supplied to the column drivers are ser to different values by the colors to apply different effective value voltages to respective picture elements of red, green, and blue. Then, the effective value voltages impressed to the respective picture elements are set properly to reduce the adverse influence of a decrease in display contrast, deterioration in color reproducibility, etc., due to rotary polarization dispersion. Consequently, the need for a data selecting circuit for each color is eliminated and the peripheral circuit is simplified.
