Hold-Type Display Motion Blur Reduction via Interpolation

The patent applies preliminary action by generating an interpolation frame signal in advance and multiplying it by a coefficient before inserting it into the video signal. This preprocessing of the video signal allows the hold-type display to reduce motion image blur without needing to increase liquid crystal response speed, as the blur-reducing effect is achieved through the pre-processed signal rather than faster pixel response.

The patent replaces the mechanical shutter system with a signal processing approach. Instead of physically shutting the backlight using a mechanical shutter synchronized with the video signal, the invention processes the video signal electronically by generating and inserting interpolation frame signals with coefficients. This substitution eliminates the need for mechanical components while achieving motion image blur reduction without affecting the flicker-free display characteristic.

The patent applies parameter changes by modifying the video signal parameters through interpolation frame generation and coefficient multiplication. Instead of changing the physical emission time of pixels, the invention alters the temporal distribution of image information in the video signal. The interpolation frames with coefficients provide intermediate image states that reduce motion blur perception while maintaining the original pixel emission duration, thus preserving screen brightness.

The patent extracts the motion image blur reduction function from the optical path (backlight shutter) and relocates it to the signal processing domain. By removing the need for physical shutter devices and implementing the blur reduction through video signal processing (interpolation frame generation and coefficient multiplication), the invention eliminates complex mechanical and control circuits while achieving the same effect through simpler electronic signal manipulation.
