Problems solved by technology

[0003] In the prior art, there are a variety of fault detection schemes, which can detect the subtle faults that occur on the LED display and obtain the specific fault data. Only by using the elimination method can we locate the specific bad point position, and because the large LED display screen consists of a large number of pixels, unit boards, and cabinets, in practical applications, only by the obtained position Data, it is difficult to quickly find the specific bad point of failure in a large display screen, so as to repair and replace it

Embodiment 1

[0020] Such as figure 1 As shown, this embodiment provides a method for locating the position of a dead pixel on an LED display screen. The method for locating the position of a dead pixel on an LED display screen is used to find the dead point in a simple and quick way when a dead pixel occurs on the LED display screen. The specific location, so as to repair and replace it.

[0021] First, the coordinate value of each pixel point in the LED display screen and the composition structure data of the LED display screen are set; for example, the coordinate value of each pixel point in the LED display screen can be set at a preset input terminal of a processing unit and the composition and structure data of the LED display screen.

[0022] Wherein, the coordinate value of each pixel point refers to the position data of each row and each column of each pixel point within the screen resolution of the LED display screen. For example, for a regular rectangular screen, the pixel point...

Embodiment 2

[0036] Corresponding to the above-mentioned examples, this embodiment provides a LED display screen dead point position positioning system, the LED display screen dead point position positioning system can be used to adopt a simple and quick method when a LED display screen has a dead point Find the specific location of the dead point, so as to repair and replace it.

[0037] The position locating system of dead pixels of the LED display screen includes a detection unit, a processing unit, a display unit and several indicating units connected to each other.

[0038] The detection unit includes several detection subunits, and each detection subunit respectively detects the display data of each pixel in the external LED display screen. Composition, a number of pixels are set on each unit board, each detection subunit can correspond to one or more pixel points for corresponding detection of its display data, each unit board can correspond to one or more detection subunits, and, ...

Abstract

The invention discloses a method and a system for positioning dead pixel positions of an LED display screen. The method comprises the following steps of: A, setting a coordinate value of each pixel point in the LED display screen and composition structure data of the LED display screen; B, detecting the display data of each pixel point in the LED display screen; C, judging whether each pixel point is a dead pixel according to the display data, if so, determining the coordinate value of each dead pixel; D, determining the position of each dead pixel in the LED display screen according to the coordinate value of each dead pixel and the composition structure data of the LED display screen to obtain position data of each dead pixel; and E, displaying the position data of each dead pixel, and indicating the position of each dead pixel. The system is correspondingly provided with a detection unit, a processing unit, a display unit and a plurality of indicating units. The method for positioning the dead pixel is simple, and can quickly find the specific position of each dead pixel so as to maintain and replace the dead pixel.

Description

technical field [0001] The invention relates to an illuminating device, in particular to a method for locating the position of dead pixels of an LED display screen and a system for locating the position of dead pixels of the LED display screen. Background technique [0002] With the development of LED display technology, LED display applications and LED lighting applications have become more and more widely used in various lighting applications due to their low energy consumption, strong color reproduction, long life, huge size, and unique shapes. Occasions, especially large-scale LED displays, are more important in major occasions or worldwide activities. [0003] In the prior art, there are a variety of fault detection schemes, which can detect the subtle faults that occur on the LED display and obtain the specific fault data. Only by using the elimination method can we locate the specific dead point position, and because the large LED display screen consists of a large n...
