Ledman Have Acquired 7 Patent Certificates Recently

By the research of State Intellectual Property Office of the P.R.C, according to Patent Law of the People’s Republic of China, Ledman have acquired 7 patent certificates recently. Respectively, Led Frame and Electronic Device of Using the Led Frame is a invention patent, Led Display Screen(1),Led Display Screen(2)and The Locking Device for fixing Module and Cabinet are utility model patent certificates, Led Display Screen(2),Led Display Screen(3) and Led Display Screen(4) are all appearance design patent certificates.

The invention patent Led Frame and Electronic Device of Using the Led Frame declares that: Led frame includes base.The reflective structure is installed on the base. There is a receiving cavity that extending through the surface of the reflective structure that away from the base and near the base. the reflective structure being spaced apart from the base,the height to the surface of the reflective structure in the direction close to the surface of the base is H; besides, the inner surface of the reflective structure is disposed at one end of the base which away from the base toward the base and the inner surface is black, The height of the reflective structure in the direction away from the surface of the base and the surface of the reflective structure near the base is H0 and the inner surface of the reflective structure which is in the vicinity of the surface of the reflective structure away from the base and the reflective structure The height in the direction of the surface is H-H0, H0 <H. This Led frame can realize high brightness, and high contrast ratio when powering up the display screen.

Utility model patent Led Display Screen (1) declares that: Led display screen includes lamp panel, which includes a plurality of LEDs arranged in a plurality of rows in the direction of the first axis, each of which includes a plurality of LEDs arranged in spaced directions along the second axis; Led module mask: there are many through-holes on it, and the mask is installed on the panel with Led pixels, and each Led pixel comes out from the through-holes; Multiple light barriers are installed on the mask, and arranged in a plurality of rows in the direction of the first axis, each line of the light barrier including a plurality of light barriers arranged in spaced apart directions in the second axis direction, and in the direction of the first axis or in the second axis direction, The number of Led pixels between the adjacent light barriers is equal to or greater than 2. Control system connected with LED can adjust the brightness of each Led that locate between the adjacent light barriers. Under the influence of light barriers, the horizontal and vertical lighting angels of the Led display screen can be adjustable.

Utility model patent Led Display Screen (2) declares that:Led display screen includes lamp panel,including a plurality of LEDs arranged in a plurality of rows in the direction of the first axis, each of which includes a plurality of LEDs arranged in spaced directions along the second axis,the mask is installed on the panel with Led pixels, and each Led pixel comes out from the through-holes; Multiple light barriers are installed and arranged in a plurality of rows in the direction of the first axis, each line of the light barrier including a plurality of light barriers arranged in spaced apart directions in the second axis direction, and in the direction of the first axis or in the second axis direction. There is only one led pixel between two adjacent light barriers, in the same straight line, the number of the lighting barriers is less than 1 piece than Led pixels. Led locating between the adjacent two light barriers, which can change the horizontal and vertical lighting angel of the Led display screen, and then, the Led display screen can be watched by a particular group of people, avoiding light pollution efficiently, strengthen the viewing effect to particular directions.
