Display module and display system for realizing network loop transmission

Abstract

The invention discloses a display module and a display system for realizing network loop transmission. The display system comprises a control host, a network switch and a plurality of display modules,the plurality of display modules are connected in series through network cables; the control host outputs a corresponding network signal according to a network video needing to be displayed, and thenetwork switch outputs the network signal to a display module connected with the network switch; and the display module converts the network signal into a network protocol signal and transmits the network protocol signal to the display screen for display, and outputs the network signal to the lower-level display module connected with the display module. Therefore, the display of the network signalon the current display module can be realized, the network signal can also be transmitted to other display screens in a ring-pass mode to be displayed, a plurality of converters do not need to be arranged, the occupied space is small, and the cost is saved. Meanwhile, a plurality of display modules are connected in series through network cables, the wiring is very simple, and the operation is convenient; therefore, the problems that an existing multi-screen display is high in cost and troublesome in wiring are solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display module and a display system for realizing network loop-through transmission. Background technique [0002] In traditional monitors or display units, most of them use CVBS (Composite Video Broadcast Signal), VGA (Video Graphics Array), HDMI (High Definition Multimedia Interface,), DVI (Digital Visual Interface), DP (DisplayPort) and other interfaces as signals. enter. When multi-screen display is required, each display unit (display unit No. 1 ~ display unit N) needs to be configured with a converter separately, such as figure 1 As shown, the control host generates multiple IP streams through the network switch and transmits them to the corresponding converters; each converter converts the received IP streams into network protocol signals that can be recognized by the display screen, and transmits them through the corresponding interfaces ( figure 1 Take the HDMI inte...
