Embodiment 1

[0041] like figure 1 As shown, the rolling screen of the present invention includes a screen composed of a plurality of LED modules arranged in a matrix. Two adjacent LED modules 1 in the same horizontal row of the screen are connected through a connector 2, and LED modules 1 in the same column are connected through two power lines 15 and a signal line 16, and the power line 15 and signal line 16 The upper end of the LED module extends into the rolling screen device 4 located above the screen for rolling up the screen, and a safe distance is maintained between the adjacent upper and lower LED modules 1, and the safe distance is used to prevent the screen from being rolled up when the screen is rolled up , adjacent LED modules interfere with each other, resulting in winding obstacles. The screen is a pixel plane, and each LED module in the screen is a pixel point, and the distance between the centers of the pixel points is 20mm-40mm, thereby effectively improving the quality o...

Embodiment 2

[0051] like Figure 8 and 9 As shown, the difference between this embodiment and the above-mentioned embodiments is that the LED module in this embodiment includes four sockets (crystal sockets) drawn out from the circuit board 18 on the housing 11 for plugging in power cords. head seat) 14'. The socket 14' is arranged on the upper surface and the lower surface of the housing 11 in groups of two. Each group one includes a socket socket with positive polarity and a socket socket with negative polarity. Preferably, the crystal sockets of the same polarity are located on the same side of the casing, so as to avoid crossing power lines during connection. At this time, the upper and lower LED modules can be connected by using the wire 15 whose end is provided with a plug connector 151 adapted to the socket 14', which is more convenient to disassemble and more secure. The electric wire is a commercially available product. The remaining parts are exactly the same as those in Emb...

Abstract

The invention discloses a rolling curtain screen, which comprises a screen formed by a plurality of LED (Light Emitting Diode) modules distributed in a matrix form, wherein adjacent LED modules in the same row are connected by a connecting member; and the LED modules in the same column are connected through at least one power cord and at least one signal wire. According to the rolling curtain screen disclosed by the invention, the power cord and the signal wire are woven in the screen of a product to form a whole, so that the power cord is prevented from being hoarded and wound at the lateral surface of the screen, potential safety hazards are reduced and the attractiveness of the screen is promoted. Furthermore, each LED module is a pixel point, so that the LED module is pointedly detached and maintained when the screen is maintained, the workload is reduced and the maintenance time and labor force are saved.

Description

technical field [0001] The invention relates to a screen display device, in particular to an LED module used for a rolling screen and a rolling screen including the LED module. Background technique [0002] At present, the LED screen display devices that are easy to transport and install on the market are basically realized in the form of flexible light strips or flexible silicone rubber tubes. After this type of LED screen display device is curled many times, the LED light-emitting element will be greatly reduced. service life. [0003] In order to solve the problem of ensuring the service life of the LED screen display device, there have been LED screen display devices that fix a plurality of equal-length rigid LED light strips on the roller blind as described in patent: 200410080603.3 and patent 200910108903.0. And this kind of LED screen display device also has some defects. For example, the power line and signal line of each LED light bar are collected on both sides of...
