The control signal applied to Ruru. For information on Light Pulp,
Transferred to the υ shift register by an external control device. When the transfer to the shift register is completed, the control terminal 2 of the drive circuit
8 changes the I/C from L level to H level, latches the state of the shift register at this time, and starts applying a corresponding drive signal to the segment electrode 21. Therefore, while the control terminal is at H level, even if the state of the shift register changes, the drive No. 100 Fi does not change. □After that, the following information is written to the shift register for 1 hour (The control signal 11 of the drive circuit becomes L level again when it is activated. Then, all drive circuits are reset), and all the segments are Start applying an off-state drive signal to the electrode 21. Immediately thereafter, the control terminal 28 becomes H level again.
The drive circuit 23 starts applying voltage to the drive 1g and r segment electrodes 21 corresponding to the state of the shift register at that time.

A 256-piece basket of 70 micron square light pulp with a pitch of 100 microns was prototyped for liquid crystal light pulp ft. 19 of the liquid crystal layer. The diameter was set to approximately 1.2 microns. Drive (gJ path is made of polysilicon j71ITF'
I' was used. The liquid crystal used is DOBAMBO. When this light pulp was subjected to a side cropping test, the response speeds of the light pulp for rising and falling were both about 50 microseconds. Also, when it was actually operated as a light pulp, the maximum writing speed was 6,000 times per second, which was a rarity. This is approximately 1
It is an order of magnitude faster gluteal speed. Same funny experience on LCD) 1
Although it was carried out using 0B80POYr, the pumping speed was rarely so'oo times per second at the maximum.As described above, the liquid crystal light pulp according to the present invention was obtained.
