AI Technical Summary

Technical Problem

Display devices with optical modules at the bottom require advanced rendering to align output timing between areas with and without the optical module, leading to potential misalignment and increased power consumption.

Method used

The display device includes a first region with a different pixel structure and a display panel driver that generates rendering data for this region during an inactive section of the data enable signal, applying data voltages based on this rendering during the active section, thereby aligning output timing and reducing power consumption.

Benefits of technology

This approach ensures synchronized output timing between regions with and without the optical module, minimizing latency and power consumption by pre-generating rendering data during inactive periods.

Abstract

The display device may include a display panel comprising a first region having a first pixel structure and a second region having a second pixel structure different from the first pixel structure, and a display panel driver that generates rendering data by rendering first region data corresponding to the first region among input image data during the deactivation period of a data enable signal, and generates data voltages applied to the first region based on the rendering data during the activation period of a data enable signal.
