Abstract: PURPOSE:To completely prevent the deterioration of the gradation of respective R, G and B and to obtain the optional white balance by controlling the basic clock used when the PWM signal is formed by the digital circuit to use the counter, to the value corresponding to the desired white balance ratio. CONSTITUTION:The device is constituted to synchronize to the input of the input data R, G and B preset to a counter 43 and change over the frequency so that a clock fck to input to the counter 43 in a PWM circuit 37 can correspond to the white balance ratio.

Thus, even when the conventional same data are inputted, the output that the number of the step is equal and the pulse width is different can be obtained, and therefore, the gradation of 6 bits and 64 steps can be completely the same by the R, G and B, an fck frequency is adjusted so that the difference in the pulse width can be the desired white balance ratio.
