Problems solved by technology

[0006] The technical problem to be solved by the present invention is that the electronic display screen in the prior art cannot be used when a fault occurs. For a device with multiple display units, each display unit works independently, and another display unit cannot repair it when a fault occurs. , so as to provide a same-screen multi-display device and its control method that can be actively repaired when a fault occurs

Embodiment 1

[0036] The structure of the same-screen multi-display device provided by this embodiment is as follows: figure 1 shown, which includes:

[0037] The display module 3 includes two groups of display units, each group of display units is controlled separately, each display point is jointly displayed by display units belonging to different groups, the brightness of the display unit is adjustable and can achieve the normal display effect of the entire display point Brightness requirements.

[0038] The display units in each group are uniformly cross-arranged on the same substrate, and the lead wires of each display unit are sealed on the back of the display unit with glue. The display unit components inside the substrate are electrically isolated from each other and can display the same content.

[0039] like figure 1 As shown, the black area in the figure represents a group of display units, and the white area represents a group of display units. All display points in the figure...

Embodiment 2

[0057] The same-screen multi-display device provided in this embodiment is based on the above-mentioned embodiments, and is used for static or dynamic information display. The schematic diagram of its display module is as follows Figure 4 shown. In this embodiment, the display module 1 is made into a rectangle. In other embodiments, the display module 1 can also be made into other shapes or combinations of different colors according to actual needs and display effects.

[0058] The control method of the multi-display device on the same screen provided by this embodiment is the same as the above embodiment, the control module 1 sends display content to the display module 3 through the control channel; when any group of displays represented by black or white When a unit breaks down, the fault detection unit corresponding to the fault detection module 2 detects whether it has a fault. If a fault occurs, the corresponding fault detection unit sends a fault signal to the control m...

Abstract

The invention relates to an on screen multi-display device which comprises a display module, a fault detection module and a control module. Each display point of the display module is displayed by display units of different groups together. Each fault detection unit of the fault detection module detects the state of each display unit corresponding to the fault detection unit. The control module controls each group of display units of the display module respectively, receives detection results of the fault detection module, performs disconnection processing on the display units having faults and adjusts the brightness of other groups of display units to lead the display points to achieve the normal display effect. The on screen multi-display device effectively solves problems in the prior art that the display function of a display unit of a display screen having faults is lost, and the display unit having faults cannot be repaired and normal use is still affected although the other display units can reduce inconvenience caused by faults of the breakdown display unit by displaying contents as same as the breakdown display unit.

Description

technical field [0001] The invention relates to an electronic display device, in particular to a multi-display device on the same screen and a control method thereof, belonging to the technical field of displays. Background technique [0002] The electronic display screen is a screen body composed of several display units (unit display board or unit display box) that can be combined and spliced, plus a set of appropriate controllers (main control board or control system). The display unit of the electronic display screen is generally a liquid crystal display LCD, a traditional light-emitting diode LED, and an organic light-emitting diode OLED. Divided into passive drive PMOLED and active drive AMOLED, organic light-emitting diode OLED has defects in power consumption and service life, so it has limitations in product size, and is often used in MP3 players and mobile phones with small screens. The traditional LED display has high brightness, low working voltage, low power co...
