A system for monitoring a back light module is provided. The system includes an obtaining unit configured to obtain an intensity of output light from the back light module, a detection unit configured to detect whether the intensity of the output light from the back light module is greater than a preset value, and a control unit configured to control the back light module to reduce the intensity of the output light in response to detecting that the intensity of the output light is greater than the preset value, such that the reduced intensity of the output light is equal to or greater than the preset value.

System and method for monitoring back light module, and a display apparatus

A backlight control method, a backlight module and a display apparatus are disclosed. The backlight control method comprises: dividing a backlight into N blocks; determining whether each of the N blocks satisfies a high current driving start-up condition or not according to a pixel signal in each input frame of image signal and determining blocks which satisfy the high current driving start-up condition as candidate blocks; setting blocks among the candidate blocks which are determined to be driven by high current as selected blocks in a case that power consumption of each frame of picture does not exceed total backlight power consumption without dynamic backlight control; and calculating backlight driving pulse width modulation duty ratios of the selected blocks according to a correspondence between brightness and pulse width modulation duty ratios, and transmitting the calculated backlight driving pulse width modulation duty ratios to a backlight driving circuit.

Backlight control method, backlight module and display apparatus

The disclosure provides a display panel, a liquid crystal display and a driving method therefor. In the display panel, each of rows and columns of pixels includes primary color pixels and white pixels arranged alternately; primary color pixels and white pixels in each row are electrically connected with different gate lines; primary color pixels in each odd-numbered row have third color, primary color pixels in each even-numbered row are arranged to alternate the first and second colors, and in any two adjacent even-numbered rows, colors of two primary color pixels located in one same column are different from each other; or, primary color pixels in each even-numbered row have third color, primary color pixels in each odd-numbered row are arranged to alternate the first and second colors, and in any two adjacent odd-numbered rows, colors of two primary color pixels located in one same column are different from each other.
