Embodiment
[0025] Please refer to figure 1 , Embodiment 1 of the present invention is: an ultra-long light bar screen, including a plurality of light bars, the head end of each light bar is provided with a clock signal input interface and a plurality of data signal input interfaces, and the end of each light bar A clock signal output interface and multiple data signal output interfaces are provided. The plurality of light bars are spliced end to end to form the ultra-long light bar screen. The ultra-long light bar screen also includes a controller, the controller includes a clock signal generator and a data signal generator, and the signal generator is connected to the clock signal input interface of the first light bar; the data signal The generator splits the data into multiple groups and connects them to multiple data signal input interfaces of the first light bar respectively. The ultra-long light strip screen also includes more than one power supply, which adopts a segmented pow...

The invention discloses a lamp strip which comprises a plurality of driver groups. Each driver group comprises a plurality of drivers, the drives in each driver group are serially connected, the input end of the lamp strip comprises a clock signal input interface and a plurality of data signal input interfaces, and each driver group is respectively connected to the clock signal input interface and one data signal input interface. The invention further discloses a super-long lamp strip screen which comprises a plurality of lamp strips, the output end of each lamp strip comprises a clock signal output interface and a plurality of data signal output interfaces, the number of the data signal output interfaces is corresponding to that of the data signal input interfaces, and the clock signal output interface and the data signal output interfaces of one lamp strip are correspondingly connected with the clock signal input interface and the data signal input interfaces of one adjacent lamp strip respectively. The super-long lamp strip screen can improve the problem that lamp strip screen signals deform when remotely transmitting, and system driving capability is limited in the prior art, and super-long transmission of the lamp strip screen signals are achieved.
Description
technical field [0001] The invention relates to the field of LED display screens, in particular to a light bar and an ultra-long light bar screen. Background technique [0002] Existing light bar screens generally use light bar cabinet splicing or single light bar parallel connection to form a complete display screen. The display screen using the cabinet splicing scheme is generally suitable for occasions with high resolution and densely arranged light bars, but not suitable for occasions where the light bars are scattered and arranged long, and control system equipment and power supplies need to be installed in each cabinet. higher cost. When conventional light strips are connected in series, signal distortion and pulse width distortion will be generated every time the signal passes through a driver, and the signal distortion and pulse width distortion will be accumulated and amplified after passing through each driver. After a certain number of drivers, the signal The wa...
