Problems solved by technology

Therefore, if a certain data line is damaged, it will cause all the LED pixel units connected to the data line to be unable to work, thus there is a problem of poor reliability to a certain extent.
In addition, when the size of the LED display device is large, it is also easy to cause data omission and errors due to the long distance of serial data transmission.

Abstract

The invention relates to a display device for solid state light-emitting elements. The display device comprises a display system and a control system. The display system comprises a plurality of arrayed pixel units and a network interface, and each pixel unit comprises a plurality of the solid state light-emitting elements. The control system comprises a control module, an input module and an output module, the output module is coupled with the network interface of the display system, the control system receives an input signal via the input module, the control module generates a corresponding control signal according to the input signal, and the output module outputs the control signal to the display system to control display contents of the display system. In the display device for the solid state light-emitting elements, the display system is configured with the network interface, which causes the control system to transmit the control signal to the addressed pixel units via a network communication protocol, thus effectively improving the reliability of the display device.

Description

technical field [0001] The invention relates to a display device, in particular to a solid-state light-emitting element display device. Background technique [0002] At present, light emitting diode (Light Emitting Diode, LED), as a solid-state light-emitting element, can be used to construct a pixel unit of an LED display device because of its low power consumption, long life, small size and high brightness. See Atsushi Okuno et al. "Unique White LED Packaging Systems" published at the 2003 IEEE Electronic Components and Technology Conference. [0003] Existing LED display devices usually include a plurality of LED light-emitting units arranged in an array, and each LED light-emitting unit includes a plurality of light-emitting diodes to build an LED pixel unit; and the data transmission of this existing LED display device is a serial connection In other words, multiple LED pixel units are connected to multiple data lines (Data Bus) in the LED display. Therefore, if a cer...
