Video timing for display systems with variable refresh rates
11594194 · 2023-02-28 · ·

A display system supports variable refresh rates that include a plurality of refresh rates. A source such as a graphics processing unit (GPU) provides frames to the display system at a selected one of the refresh rates. The refresh rates are factored into a corresponding plurality of prime factors. A plurality of numbers of lines per frame in frames provided at the plurality of refresh rates is determined based on one or more ratios of the plurality of refresh rates, the plurality of prime factors, and a line rate for providing frames to the display system at the plurality of refresh rates. The source then selectively provides frames to the display system at one refresh rate of the plurality of refresh rates using the same line rate regardless of which refresh rate is chosen. Furthermore, the number of lines per frame is an integer for frames provided at the refresh rates.

DISPLAY DEVICE AND DISPLAY METHOD
20180005560 · 2018-01-04 ·

A display device includes a display panel, a driver, a detector, and an acquisition part. The driver drives the display panel based on a video signal. The detector obtains a first detection value by detecting reflective light from reflective media, which occurs when ambient light is irradiated to reflective media, while obtaining a second detection value by detecting reflective light from reflective media, which occurs when the display panel irradiates its display light to reflective media. The driver corrects a drive value for the display panel such that the second detection value approaches the first detection value or such that the chromaticity represented by the second detection value approaches the chromaticity represented by the first detection value, and therefore the acquisition part acquires information concerning the color temperature of ambient light based on the corrected drive value.
