Inventor: NISHI TAKESHI
IPC: G09G3/36
Filed: 1995-05-10
Abstract: PURPOSE:To enable a definite gradational display with a large number of gradations by checking the relation between an applied voltage value and a pixel voltage right before the voltage is applied and applying the voltage which has a proper value. CONSTITUTION:A driving circuit 201 consist roughly of a driving waveform generation source 202 which outputs a driving waveform to signal electrodes, scanning electrodes, and an opposite electrode and a pixel voltage detection part 203 which detects a pixel electrode voltage value to the opposite electrode. Then the voltage value (pixel voltage value) between the opposite electrode and the electrode of a selected pixel in a bright (or transmission) or dark (or nontransmission) display state is detected and when the current display state (bright or dark) is the same as the last display state, the voltage having a pixel voltage value less than the detected pixel voltage value and also has the same polarity is applied. When the current display state is different from the last display state, the voltage having a pixel voltage larger than the detected pixel voltage value and also has the different polarity is applied to the pixel electrode.

IPC: H04N5/445
Filed: 1994-06-17
Abstract: PURPOSE:To effectively clear a memory area storing the broadcast station names and also to improve the control job efficiency when a TV receiver is shipped at a plant or the memory is replaced with another, to improve the channel selecting operation efficiency, and to prevent the display of wrong broadcast station names in reference to the TV receiver which displays a selected broadcast station name on a CRT. CONSTITUTION:A channel selection memory puts the blank data into only the 1st byte of a 4-byte memory area storing the broadcast station names before a TV receiver is shipped at a plant or the memory is replaced with another. Then an operator stores the tuning data and a broadcast station name at each position of the memory. When a position is designated in a channel selecting operation mode, the tuning data and the broadcast station name data (S3) are read out of the memory. Then only the 1st byte of the memory area storing data are detected, the character signals (4). If the character data are detected, the character signals are displayed on a CRT (S11) and otherwise no data is displayed (the blanks are displayed) (S13).

So the second shutter can be opened only for a specified period so as to use the target on which the shutter plate is mounted. Hence, materials for sputtering can be prevented from going round for sticking, so that electrical characteristics of a semiconductor device can be prevented from being deteriorated.
