发明名称 Recording apparatus
摘要 In a recording apparatus of this invention, liquid crystal light shutter operates by using the double frequency drive. The double frequency drive employs a high frequency fH and lower frequency fL. The dielectric anisotropy becomes positive in the case of the lower frequency fL than crossover frequency fC and becomes negative in the case of the higher frequency fH than the frequency fC of liquid crystal material. The driver circuit of liquid crystal light shutter includes a delay circuit (146). Both a recording data delayed through the delay circuit (146) and a recording data formed without going through the delayed circuit (146) are produced in an LSI, to be supplied to write selecting electrodes and signal electrodes of the liquid crystal light shutter, thereby driving the liquid crystal light shutter in a time sharing manner.
