Problems solved by technology
However, at present, this kind of special detection equipment is still relatively expensive, and there is no other product that can directly convert the picture parameters of the two monitors into corresponding ones.
Therefore, after purchasing several monitors that have been calibrated for the first time from the manufacturer, if the practitioners do not have the relevant testing equipment, when the screen performance of the monitors naturally decays in the future, they can only consider sending them to the factory for calibration or relying on manual adjustments and visual judgments. Calibration operations between each other make it difficult to balance cost and calibration quality

Embodiment Construction
[0023] Please refer to FIGS. 1A and 1B , which are two schematic diagrams of a display device according to a preferred embodiment of the present invention. The display device 100 includes a main body 110 and a light sensing device 120 , and the light sensing device 120 is coupled to the main body 110 by a connection line L. As shown in FIG. As shown in FIG. 1A , the front of the main body 110 has a screen 111 for displaying images, and the user can generally adjust the picture parameters (such as brightness or contrast) of the screen 111 through several buttons on the main body 110 . In addition, if Figure 1B As shown (a side view of FIG. 1A ), the main body 110 also has a control module 112 coupled to the screen 111 for controlling the brightness of the screen 111 . The light sensing device 120 can generate a sensed brightness value according to the brightness sensed by the light receiving part 121 , and the control module 112 receives the sensed brightness value through th...

The invention relates to a display device and a luminance correction method. The display device comprises a body and a light sensing device, wherein the light sensing device is coupled with the body through a connecting wire; the body has a screen and a control module; the control module is coupled with the screen and is used to control the luminance of the screen; the light sensing device generates sensing luminance value according to the sensed luminance; and the control module receives the sensing luminance value by means of a connecting wire. The display device can be simply adjusted to needed luminance behavior and has high correction accuracy and cost within an acceptable scope.
Description
technical field [0001] The present invention relates to a display device and its brightness correction method, and in particular to a display device capable of directly performing brightness correction with a target light source and its brightness correction method. Background technique [0002] In professional fields such as art advertisement design or printing and publishing practitioners that require high display performance, the screens of several monitors used in the operation must have as consistent picture parameters (such as brightness and color, etc.) as possible to achieve desired finished product quality. Therefore, practitioners may have to have relevant testing equipment (such as a signal generator (pattern generator)) to perform calibration by themselves, or require the display manufacturer to perform calibration in advance when ordering. However, this special testing equipment is still relatively expensive at present, and there is no other product that can di...
