Problems solved by technology

However, since shooting is performed multiple times with the interval of each individual LED measurement, there is a problem that the time taken for measurement is long
[0005] In addition, even if correction is performed by eliminating the interference between LED elements with spacing, the user will recognize the image where the interference occurs, causing a difference in color gradation

Embodiment Construction

[0043]Example embodiments will be described in detail below with reference to the accompanying drawings. For reference, in describing known functions or configurations, when it is determined that the detailed description may obscure the gist of the exemplary embodiments, the detailed description thereof will be omitted. In addition, the exemplary embodiments can be changed in various forms, so the technical scope is not limited to the following exemplary embodiments. Rather, these example embodiments are provided so that this disclosure will be thorough and complete.

[0044] Unless expressly stated otherwise, the term "comprising" will be understood to imply the inclusion of a certain component, but not the exclusion of any other components. In addition, various elements and regions in the drawings are schematically drawn. Therefore, the present technical concept is not limited by relative sizes or intervals drawn in the drawings.

Abstract

A display apparatus, a calibration apparatus and a calibration method thereof are provided. The display apparatus includes a display including display modules, a storage configured to store a correction coefficient of each of light emitting pixels included in each of the display modules, and a processor configured to apply the correction coefficient of each of the light emitting pixels respectively to a pixel value of each of the light emitting pixels to correct the pixel value of each of the light emitting pixels. The correction coefficient of each of light emitting pixels is determined basedon a first target value for uniformity between pixels, and the first target value is determined based on one or more representative pixel values of the display modules.

Description

technical field [0001] Devices and methods according to example embodiments relate to a display device, a calibration device and a calibration method thereof, and more particularly, to a display device including a self-luminous element, a calibration device and a calibration method thereof. Background technique [0002] A Light Emitting Diode (LED) is a semiconductor light emitting diode that converts electrical current into light. Recently, LEDs have been increasingly used as display light sources, automotive light sources, and lighting light sources. In addition, a light emitting diode emitting white light with excellent efficiency can be realized by using a fluorescent material or by combining light emitting diodes of various colors. [0003] Such light-emitting diodes can be mass-produced in the form of light-emitting element packages. Mass-produced light-emitting element packages are used as light sources by classifying the light-emitting element packages according to...
