A method computes drive currents for LEDs in a pixel of a signboard to achieve a desired color at a desired luminous intensity. This method is particular applicable to a signboard having pixels made up of four (4) or more primary colors. The method selects a number of colors within a color gamut, and for each selected color, the method computes drive currents for the LEDs of each basis color, such that the resulting luminous intensity of the selected color is maximum. Using the computed drive currents, the method then scales the drive currents to achieve the desired luminous intensity in the desired color. The drive currents may be computed, for example, using a constrained maximization technique, such as linear programming. In one embodiment, the drive currents for each selected color are computed subject to the constraint that none of the drive currents is negative, and that their total is less than a predetermined value. In one embodiment, the selected color is expressed in the units of a linear color space.

To suppress degradation of a transistor. A method for driving a liquid crystal display device has a first period and a second period. In the first period, a first transistor and a second transistor are alternately turned on and off repeatedly, and a third transistor and a fourth transistor are turned off. In the second period, the first transistor and the second transistor are turned off, and the third transistor and the fourth transistor are alternately turned on and off repeatedly. Accordingly, the time during which the transistor is on can be reduced, so that degradation of characteristics of the transistor can be suppressed.

The present disclosure relates to a driving backplane, a micro-LED display panel and a micro-LED display device.
