Abstract

According to the embodiment, the invention discloses a display correction method, a display correction device and a display correction system of a display panel. The method comprises the following steps: acquiring monochromatic display brightness, under various gray scales, of various color sub-pixels when a reference display panel displays in monochrome, and acquiring monochromatic theoretical brightness when the reference display panel displays in white; acquiring a corresponding relation between input voltage and display brightness when a to-be-detected display panel displays in monochromatic; calculating target theoretical brightness of the various color sub-pixels in accordance with white target brightness and white target chroma when the to-be-detected display panel displays in white under a preset gray scale; searching a target gray scale corresponding to monochromatic theoretical brightness which is equal to target theoretical brightness, and searching monochromatic display brightness corresponding to the target gray scale; determining corresponding input voltages of various color sub-pixels of the to-be-detected display panel when the monochromatic display brightness is displayed; and determining target input voltage of the to-be-detected display panel in accordance with a chroma difference value and a brightness difference value. According to the embodiment, display correction method provided by the invention is short in consumed time and suitable for large-scale debugging.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a display calibration method, device and system for a display panel. Background technique [0002] With the development of display technology, the display effect of the display panel is continuously improved, so that the application of the display panel becomes more and more extensive. [0003] The grayscale curves of display panels are different in different display fields. In addition, due to the differences in production processes and components such as driver chips, display panels cannot achieve a normal white balance state and display differences between different display panels are large. [0004] In order to meet customers' requirements for product consistency and customization, each display panel will be optically corrected during production. However, the current calibration method takes a long time and is not suitable for batch debugging. Contents of t...
