According to various embodiments of the invention, gamma curves for multiple pixel groups can be calibrated using look-up tables or by using reference voltage groups provided by gamma voltage generators so that the pixels can display multiple images with correct gray levels at different view angles. In addition, high-speed pattern inspection can be carried out without changing the image comparison algorithm. The resonance circuit cooperates with the inverter. The animation system determines the values of animation variables at their modified times, rather than at the time of the blur frame, and poses objects or portions thereof accordingly.
