Abstract

One or more apparatuses and methods for enabling easy diagnosis, repair, and maintenance of a commercial display screen are disclosed. In one embodiment of the invention, this apparatus includes a removable commercial display kit box, a corresponding base plate interface unit attached to a rear panel of the commercial display screen, and a guiding mechanism for docking the removable commercial display kit box and the corresponding base plate interface unit. Furthermore, in one embodiment of the invention, the removable display kit box contains an analog-to-digital converter board, a power board, automatic-switching dual data ports, maintenance check visual indicators, and a removable fuse inlet. In case of a commercial display screen malfunction, the removable display kit box allows a quick inspection and a modular repair or replacement of a malfunctioning part, without requiring the entire commercial display screen to be dismounted from a wall or another attached structure.

Claims

1. An apparatus for easy diagnosis, repair, and maintenance of a commercial display screen, the apparatus comprising:

a removable commercial display kit box with electrical contact pin-outs configured to be docked into a corresponding base plate interface, wherein the removable commercial display kit box contains automatic switching dual data ports that incorporate an embedded software executed on a microcontroller unit (MCU) to check whether a first sync detector connected to a first DVI input port, which is designated as a currently-sourced input port, is reporting a normal signal, an abnormal signal, or no-signal from the first DVI input port, wherein the abnormal signal or the no-signal for the first DVI input port invokes the embedded software to instruct a DVI switch to automatically change the currently-sourced input port to a second DVI input port connected to a second sync detector, if the second sync detector is reporting a normal backup signal from the second DVI input port;

the corresponding base plate interface operatively connected to power inverters and low-voltage differential signaling (LVDS) system that are located outside of the removable commercial display kit box, wherein a docking between the corresponding base plate interface and the electrical contact pin-outs from the removable commercial display kit box provides docket electrical connections among the power inverters and the LVDS system, which are located outside of the removable commercial display kit box, and the automatic switching dual data ports inside the removable commercial display kit box; and

one or more locking safety pins configured to provide a securely attached position between the removable commercial display kit box and the corresponding base plate interface.

2. The apparatus of claim 1, further comprising maintenance check visual indicators on a surface of the removable commercial display kit box, wherein each visual indicator shows a particular functional or operational status associated with the commercial display screen.

3. The apparatus of claim 2, wherein the maintenance check visual indicators comprise a plurality of light-emitting diodes (LED'"'"'s) capable of blinking or changing colors.

4. The apparatus of claim 1, further comprising a precision tracking system which includes a first guide rail and a second guide rail attached to a base plate on a rear panel of the commercial display screen, wherein the first guide rail and the second guide rail are configured to guide side edges of the removable commercial display kit box to align and dock correctly with the corresponding base plate interface.

5. The apparatus of claim 1, further comprising a removable fuse inlet on a surface of the removable commercial display kit box, wherein the removable fuse inlet contains a replaceable electrical fuse which is replaceable externally, without opening the removable commercial display kit box.

6. The apparatus of claim 1, further comprising a first wall mount frame and a second wall mount frame, both of which are operatively attached to a base plate on a rear panel.

7. The apparatus of claim 3, wherein the plurality of light-emitting diodes (LED'"'"'s) include a first LED for indicating a system monitoring activity status, a second LED for indicating a backlight lamp activity status, a third LED for current temperature of the commercial display screen, one or more LED'"'"'s for power output levels within the commercial display screen, and one or more LED'"'"'s for current connectivity and functional statuses of multimedia data input ports.
