Embodiment 1

[0024] Such as figure 1 As shown, this embodiment provides a display system for point-by-point brightness adjustment. The point-by-point brightness adjustment system includes a storage device and a display device.

[0025] The display device is provided with at least one group of LED light-emitting diodes and a drive control module thereof; wherein each group of LED light-emitting diodes includes at least one LED light-emitting diode, and each LED light-emitting diode may be a red LED light-emitting diode or a green LED light-emitting diode, Or blue LED light-emitting diodes; the drive control module is used to drive and control each group of LED light-emitting diodes, so that each group of LED light-emitting diodes can display various graphics, characters, animations, etc. according to requirements.

[0026] For example, each group of LED light-emitting includes a red LED light-emitting diode, a green LED light-emitting diode and a blue LED light-emitting diode; more specifically, ...

Embodiment 2

[0036] Such as figure 2 As shown, on the basis of the foregoing examples, the storage device is provided on the display device.

[0037] The storage device is arranged on the display device, and can be arranged at any position of the display device, which saves the space occupied by the display system for point-by-point brightness adjustment in this embodiment, and has a simple structure; when the display needs to be adjusted When each LED light-emitting diode in the device is adjusted, the adjustment data can be called out in time for adjustment, and the operation is simple and convenient, and the operation is not restricted by time and place.

Embodiment 3

[0039] Such as image 3 As shown, on the basis of the above examples, the display system for point-by-point brightness adjustment further includes a processing device; the processing device is connected to the storage device, and the processing device is used to produce adjustment data and store it in the storage device. And, the processing device is also connected to the display device via the storage device, and is used to send the adjustment data to the display device to adjust the brightness of each LED light-emitting diode on the display device.

[0040] Wherein, the performance parameters of each LED light-emitting diode in the display device are input into the processing device, for example, the brightness and wavelength of each LED light-emitting diode are input. The processing device can obtain the results according to the brightness and wavelength of each LED light-emitting diode. When the display device has the best display effect and the display brightness is uniform, ...

Abstract

The invention discloses a display system of point-to-point brightness control and a method. The display system comprises a storage device and a display device; wherein, the display device is provided with at least a group of LEDs and a drive control module thereof; the storage device is provided with a table of adjustment data used for corresponding to each LED of the display device and storing the adjustment data; the storage device is also used for providing the adjustment data to the display device; the drive control module is used for controlling each group of LEDs by drive according to integration of first display data of the adjustment data; the brightness and lighting angle of each LED in the display device are adjusted by the display system to ensure that the display device has uniform display and good display effects.

Description

Technical field [0001] The present invention relates to the technical field of image display correction, and in particular to a display system with point-by-point brightness adjustment, and a method for using the display system to perform point-by-point brightness adjustment. Background technique [0002] The LED display is composed of hundreds of thousands or even millions of semiconductor light-emitting diodes, namely: LED lamp points. Various factors such as different optical characteristics of the lamp point, component aging, drive error, inconsistent angle of the lamp point, dust of the lamp point, and cap brim to protect the lamp point will cause uneven brightness of the screen lamp point. At present, the main ways to solve this non-uniformity phenomenon are: one is to improve the uniformity of the optical characteristics of the LED lamp, and the other is to improve the uniformity of the display screen through correction. The consistent method to improve the optical charac...
