The present disclosure provides a driving method of a display module, a driving system thereof, and a display device. The driving method of the display module includes a display panel driving process, and a backlight module driving process driven synchronously with the display panel driving process. The display panel driving process includes steps: performing a color saturation adjustment; and obtaining second color signals to drive the display panel by converting. The backlight module driving process includes steps: using the light source adjustment coefficient to adjust a first brightness value to obtain a second brightness value; determining a dominant hue light source; and driving the dominant hue light source by the second brightness value.

A method includes determining a number of drive pulses of equal width and amplitude that would drive LEDs with a total charge during a frame. If the width of the drive pulses is greater than a minimum-width and less than a maximum-width, the LEDs are driven with the drive pulses. If the width of the drive pulses is less than the minimum-width and an amplitude of the drive pulses is greater than a minimum-amplitude, decrement the amplitude of the drive pulses and recalculate the width of the drive pulses so each drive pulse has the decremented amplitude and recalculated width. If the amplitude of the drive pulses is equal to the minimum-amplitude, reduce the number of drive pulses and recalculate the width and amplitude of the reduced number of drive pulses. If the amplitude of the drive pulses is equal to the minimum-amplitude, the LEDs are not driven.

A near-eye display device comprises a pupil-expansion optic, first and second lasers, a drive circuit coupled operatively to the first and second lasers, a beam combiner, a spatial light modulator (SLM), and a computer. The first and second lasers are configured to emit in respective first and second wavelength bands. The beam combiner is configured to geometrically combine emission from the first and second lasers into a collimated beam. The SLM is configured to receive the collimated beam and to direct the emission in spatially modulated form to the pupil-expansion optic. The computer is configured to parse a digital image, trigger the emission from the first and second lasers by causing the drive circuit to drive current through the first and second lasers, and control the SLM such that the spatially modulated form of the emission projects an optical image corresponding to the digital image.

An electronic device may include a display having an array of pixels and a backlight that provides backlight illumination for the array of pixels. The backlight may be a direct-lit backlight with a two-dimensional array of light-emitting diodes operable in a local dimming scheme. The electronic device may include control circuitry that provides pixel signals to the array of pixels and backlight signals to the backlight. The control circuitry may adjust the pixel signals and the backlight signals to compensate for brightness and color non-uniformity in the backlight. To compensate for image-dependent backlight non-uniformity, the control circuitry may simulate artificial backlight data based on the target image to be displayed and stored point spread information. To compensate for white-point-dependent backlight non-uniformity, the control circuitry may use measured actual backlight data that describes color variations across the backlight for a given target white point.
