    Abstract: Methods and apparatuses for backlight calibration are described. The backlight calibrating apparatus (100) comprises a backlight unit (102) comprising a plurality of light sources (120), at least one photo sensor (103) adapted to measure the light emitted by the backlight unit (102), a photo sensor controller (112) coupled to the photo sensor(s) (103) for controlling the photo sensor(s) (103), a backlight driving circuit (104) coupled to the light sources (120) for providing individual driving on each light source, a signal generator (114) coupled to the photo sensor controller (112) and the backlight driving circuit (104) for controlling the operation timing of photo sensor(s) (103) and each the light source (120) such that lighting conditions from each the light source (120) can be acquired, and a processing unit (111) coupled to the photo sensor(s) (103) and the backlight driving circuit (104) for analyzing the measurement data from the photo sensor(s) (103) and providing an adjustment signal to the backlight driving circuit (104) to achieve uniform lighting conditions of the backlight unit (102). The method of calibrating a backlight apparatus comprises the steps of providing saved settings for a backlight driving circuit (104), providing a modified timing sequence to the backlight driving circuit (104) and at least one photo sensor (103), measuring light conditions of each individual light source or each individual group of light sources (120) in backlight unit (102), comparing measurement data with predefined light condition, calculating the adjustment required on backlight driving circuit (104) to achieve desired light conditions, and saving the calculated adjustment as new settings for backlight driving circuit (104).

    Abstract: A system and a method are provided for maintaining accurate visual color performance of displays. In particular, various embodiments of the present invention described herein provide a system wherein partial color certification is incorporated into the calibration procedure. In the event that the partial color certification is out of tolerance, a full certification procedure is performed. If the full certification procedure is out of tolerance, the calculated errors of the certification procedure are utilized to perform an update to a baseline profile for the display. The updated baseline profile can either replace the existing baseline profile or can be concatenated with the baseline profile to preserve the baseline behavior of the display.

    Abstract: A calibration system and a calibration method for a multi-display system are disclosed. Test patterns displayed on each screen of the multi-display system are captured by a handheld device. One of the captured images corresponding to a specific display is designated as a standard image such that the handheld device can compare the other captured images corresponding to the other displays with the standard image to determine at least one adjustment parameter for each display. The images output to each display can be adjusted according to the adjustment parameter so as to eliminate the display differences between the images.
