Embodiment 1

[0024] Such as figure 1 As shown, this embodiment provides a display system for point-by-point brightness adjustment, and 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 set of LED light-emitting diodes and its drive control module; wherein, each set of LED light-emitting diodes includes at least one LED light-emitting diode, and each LED light-emitting diode can 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 lights includes a red LED light-emitting diode, a green LED light-emitting diode and a blue LED light-emitting diode; more specifically, the dr...

Embodiment 2

[0037] like figure 2 As shown, on the basis of the above examples, the storage device is arranged on the display device.

[0038] The storage device is arranged on the display device, and can be arranged at any position of the display device, which saves the occupied space of the display system for point-by-point brightness adjustment in this embodiment, and has a simple structure; when the display device needs to be adjusted When each LED light-emitting diode in the device is used, the adjustment data can be called out in time for adjustment, the operation is simple and convenient, and the operation is not limited by time and place.

Embodiment 3

[0040] like image 3 As shown, on the basis of the above examples, the display system for point-by-point brightness adjustment also includes a processing device; the processing device is connected to the storage device, and the processing device is used to generate adjustment data and store it in the storage device , and the processing device is also connected to the display device through 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.

[0041] 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, and the processing device can obtain the When the display device has the best display effect and the display brightness is uniform, the brightness range of each LED light-emitting diode can be used to obtain th...

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 invention relates to the technical field of image display correction, in particular to a display system for point-by-point brightness adjustment and a method for point-by-point brightness adjustment using the display system. Background technique [0002] The LED display screen is composed of hundreds of thousands or even millions of semiconductor light-emitting diodes, namely: LED light points. Various factors such as different optical properties of the light points, component aging, drive error, inconsistency in the angle of the light point itself, dust on the light point, and shielding of the hat brim to protect the light point will cause uneven brightness of the light point on the screen. At present, the main ways to solve this uneven phenomenon: one is to improve the consistency of the optical characteristics of LED lights, and the other is to improve the uniformity of the display screen by means of correction. The consistent way to improve th...
