An apparatus for dynamically controlling backlight source receives a pixel input data, and outputs a pixel output data and a PWM signal. The apparatus includes image analysis unit for receiving the pixel input data and outputting image data after performing image analysis. An information unit stores relation data including luminance adjusting data and PWM adjusting data corresponding to gray level range. A luminance calculation unit receives the image data from the image analysis unit and the relation data from the information unit, and calculates a required gray level corresponding to a required luminance, and outputs a required pixel luminance data and a required PWM data according to the required gray level. A PWM adjusting unit receives the required PWM data and outputs the PWM signal. A multiplication unit receives the pixel input data and performs luminance adjustment according to the required pixel luminance data for outputting the pixel output data.

A mixed color controlling method for backlight module and display device using the same, in the method, a mixed color sequential (MCS) algorithm with high contrast enhancement technique is provided in RGB LED backlight display. Owing to synchronous control of LCD panel and LED backlight module, high quality image with suppressed color breakup and motion blur effects is achieved, and display contrast is improved by our novel color sequential technique. In addition, MCS algorithm is useful for color filter-less optical compensated bend (OCB) panel display for alleviating color breakup and motion blur effects.

Reducing data transitions in a data transmission interface includes receiving first data and second data, among which the first data is data being transmitted by the data transmission interface and the second data is next data of the first data in a timing sequence. Corresponding data bits of the first data and the second data are compared to compute how many data bits undergo data transition. If the number of data bits undergoing data transition is greater than half the number of data bits the data transmission interface is capable of transmitting simultaneously, an encoding mode is activated to encode the second data, and an encoding result corresponding to the second data is outputted.

A color-zone layout of light-emitting module includes at least a light-emitting zone unit. The light-emitting zone unit includes a plurality of blocks, which are divided into a first color-zone, a second color-zone, a third color-zone and a fourth color-zone. A fifth color-zone is located between any two adjacent ones of the color-zones. The five color-zones simultaneously display within a display frame.
