Description
Technical Field
The utility model relates to the field of LED display screens, in particular to an LED motion display screen.
Background
The prior art LED display screens are divided into the following:
the first type is that all accessories such as LEDs, circuit boards and the like on the display screen are completely fixed after being installed, and when the display screen is started for use, video playing is carried out under the condition that all accessories are completely fixed.
And 2, the other type is a fan screen, wherein a plurality of LED light bars replace fan blades of a fan, the fan blades are arranged on a fan motor, the fan blades are driven by the motor to rotate at a high speed, and then the LEDs on the light bars are controlled to emit light in a rotating state to generate a video picture.
The display screen of the 1 st type must require that the LEDs on the display screen, the pitch of the horizontal LEDs and the pitch of the vertical LEDs must be the same pitch, which results in a large number of used LEDs and high cost, and especially when a high-pixel high-definition display screen is made, for example, P2, i.e., the horizontal and vertical center distances of the LEDs are all 2mm, and the number of LEDs per square is 500 × 500 — 250000 thousands of LED beads, which results in high cost.
The display screen of the 1 st type can obviously display one light spot when a video is played even if the pixel points are high because the LED completely emits light at a fixed position and does not emit light in the motion state of the LED.
Although the 2 nd display screen is that the LED emits light under the high-speed motion, because the fan-type fan blade lamp strip rotates around the axis, the linear velocity of motion of each LED on the fan blade lamp strip is different, the linear velocity of motion of the LED far away from the axis is fast, and the linear velocity of motion of the LED near the axis is slow, which causes great limitation on designing screen video, and complicated fast-changing movie video pictures are difficult to realize.
In addition, as the fan displays a circular video picture when rotating, under the rotating state, when the brightness of each LED is consistent, the brightness of the picture of the display screen far away from the axis is lower than that of the picture close to the axis, and when the uniform brightness is controlled at each position of the display screen, the LED farthest from the axis is controlled to have the maximum brightness, the brightness of each LED is gradually weakened towards the axis in sequence, the brightness of the LED at the axis is weakest, so that the brightness of the LED is sacrificed when the brightness of the whole fan is viewed on average, and the brightness of the whole fan screen is very low.
In addition, the display screen is a rectangular or square display surface, or a curved display screen with the same length of the upper and lower sides and the same width of the two sides, so that the display screen can be smoothly consistent with the movie and television images. However, the fan screen generates a circular screen, and if a square video screen is displayed, the effective square part in the circle must be cut out for use, and the rest is wasted useless area.
From the perspective of the pixel points, the fan blades rotate around the axis to form the display screen, and even if the display screen rotates, the height consistency of each pixel point is difficult to achieve.
The display screen of the utility model is a brand-new display screen, not only overcomes the weakness of the display screens of the above types, but also creates a brand-new major category of the display screen industry.
The LED motion display screen is manufactured by the following method, the problems are solved, the defects of the prior art are overcome, and the specific method is as follows:
