Abstract:
1. A display panel comprising: a display unit comprising pixel elements arranged in a matrix; a scanning circuit and a signal circuit arranged to drive pixel elements; a multi-input type level conversion circuit arranged to generate control signals, and to perform level conversion of image signals having a low voltage amplitude into image signals having a high voltage amplitude to the scanning circuit and the signal circuit to drive the pixel elements; a differential input type level conversion circuit arranged to perform level conversion of differential clock signals having a low voltage amplitude into clock signals having a high voltage amplitude to control transmission of image signals to the signal circuit to drive the pixel elements; and a latch circuit arranged to latch the image signals having the high voltage amplitude to the signal circuit in accordance with the clock signals having the high voltage amplitude; wherein the signal circuit and the scanning circuit are driven to provide a visual display of images corresponding to the image signals latched from the latch circuit in accordance with the control signals generated from the multi-input type level conversion circuit.
