Abstract: Provided is a display drive system, including: a plurality of drive units and a control unit. The plurality of drive units are connected to a lamp panel, and at least one of the plurality of drive units is configured to drive, during a display stage, the lamp panel to emit light. The control unit is connected to the plurality of drive units, and is configured to detect an operating state of the drive units driving the lamp panel to emit light. In response to detecting that a first drive unit is abnormal, the lamp panel is driven, by a second drive unit, to emit light, wherein the first drive unit is at least one of the drive units driving the lamp panel to emit light, and the second drive unit is at least one of the plurality of drive units other than the first drive unit.

Abstract: A method and device for modulating a brightness-grayscale curve of a display device are provided. The method includes determining an applicable standard brightness-grayscale curve for eye perception; obtaining theoretical brightness values corresponding to respective grayscales of the display device based on the applicable standard brightness-grayscale curve for eye perception and at least one of an eye pupil change factor, an environmental factor and a factor related to the display device; modulating brightnesses of the display device according to the theoretical brightness values corresponding to the respective grayscales of the display device. The above method is a solution to the problems of low grayscale details, backlighting, high grayscale saturation, and transition-color unevenness. The problem is solved that a visible grayscale in a dimmed session is no longer distinguishable in a bright environment. And a quantifiable standard for modulation control is provided.
