Printhead substrate inputting a data signal and a clock signal, printhead, printhead cartridge, and printer thereof |
摘要 |
Printhead substrate for inputting a data signal (DATA) in synchronization with a clock signal (CLK). The printhead substrate comprises: input terminals inputting the clock signal and data signal; shift registers inputting and maintaining the data signal in synchronization with the clock signal inputted from the input terminals; and a time lag adjuster arranged between an input terminal and the shift register to adjust a time lag of at least one of the clock signal or data signal. By virtue of adjusting the time lag by the time lag adjuster, setup time and hold time between the clock signal and the data signal inputted to the shift register is ensured.
