Therefore, the utility model can realize automatic detection on the blind points of a display panel.
Description
Technical field
The utility model relates to a kind of display system with blind spot measuring ability.
Background technology
As the full-color advertisement screen of the outdoor LED of outdoor light-emitting display device, the heating high temperataure phenomena of the full-color advertisement screen of LED is comparatively common under long-term unattended duty situation, yet because display panel is made up of numerous light emitting diodes (LED), and being in the hot operation state for a long time, the LED lamp burnt out very easily, so just blind spot occurred at display panel, because each LED lamp only is a pixel of display panel, therefore, when on display panel, forming blind spot, rely on human eye may be difficult in time discover when having only a few LED lamp to break down.Moreover, as being installed in outdoor display screen, most of the time is the state that is in no supervision, even if large-area blind spot therefore occurs, also may be difficult in time be discovered because of unattended duty, therefore, how to realize the automatic detection of blind spot has been become the technical task that those skilled in the art need to be resolved hurrily in fact.
The utility model content
The purpose of this utility model is to provide a kind of display system with blind spot measuring ability, to realize the automatic detection to the display panel blind spot of being made up of the LED lamp.
Reach other purposes in order to achieve the above object, the display system that the utility model provides with blind spot measuring ability, comprise the display panel that a plurality of light emitting diodes constitute, be connected with described a plurality of light emitting diodes respectively and be used to drive the chip for driving of described display panel by each pin, be used for providing the video control module of video driving signal to described chip for driving, be used for providing the main control system of video information to be shown to described video control module, it is connected with described chip for driving, be used for sending the blind spot detection signal to described chip for driving, and read the electric current of described chip for driving described each pin output after receiving described blind spot detection signal, and record current unusual pin occurs to detect the blind spot detection chip that the light emitting diode that is connected with described pin is a blind spot.
Wherein, described electric current occur comprising unusually electric current be 0 or electric current excessive.
Preferably, the model of described chip for driving is MBI5026 or MBI5024.
Preferably, described display system with blind spot measuring ability also can comprise and be used to each light emitting diode distribution plan of showing that described display panel has, and the pin that is write down according to described blind spot detection chip is labeled in blind spot display device in the described distribution plan with corresponding blind spot.
Preferably, described display panel is arranged on the open air.
In sum, the display system with blind spot measuring ability of the present utility model pass through in existing display system, increase the blind spot detection chip and can realize the blind spot of the display panel be made up of the LED lamp is detected automatically.
Description of drawings
Fig. 1 is the structural representation with display system of blind spot measuring ability of the present utility model.
Embodiment
See also Fig. 1, the display system with blind spot measuring ability of the present utility model comprises: display panel, chip for driving, video control module, main control system, blind spot detection chip, blind spot display device.
The a plurality of light emitting diodes of described display panel (LED lamp) constitute, usually for color display panel, each pixel all comprises the three-color LED fluorescent tube that sends RGB light, owing to the structure of display panel is familiar with by those skilled in the art, so be not described in detail in this.In the present embodiment, described display panel is arranged on the open air.
Described chip for driving has a plurality of pins, be connected with the light emitting diode of described display panel respectively, be used to drive described display panel, promptly by each pin to corresponding light emitting diode input current so that each lumination of light emitting diode, but MBI5026 that the model Macroblock company of described chip for driving produces or MBI5024 etc.
Described video control module is used for providing video driving signal to described chip for driving so that described chip for driving as required content displayed import corresponding electric current from each pin to each light emitting diode.
Described main control system is used for providing video information to be shown to described video control module, usually the video file that needs demonstration by the control personnel to the main control system input, by described video control module corresponding video file is converted to the drive signal that described chip for driving can be discerned then, again by described chip for driving according to the described display panel of described drive.
Described blind spot detection chip is connected with described chip for driving, be used for sending the blind spot detection signal to described chip for driving, and read the electric current of described chip for driving described each pin output after receiving described blind spot detection signal, and the unusual pin of record current appearance is a blind spot to detect the light emitting diode that is connected with described pin, for example, when needs carry out the blind spot detection, described blind spot detection chip is sent detection signal, described then chip for driving makes each pin all export high level according to described detection signal, described then blind spot detection chip reads the electric current of each pin output of described chip for driving, when the electric current of a certain pin occurs unusual, be that circuit is 0 or when excessive (being overrun), the numbering of its record respective pins, can judge the abnormal demonstration of the light emitting diode that is connected with described pin thus, promptly become blind spot.
Described blind spot display device is used to each light emitting diode distribution plan of showing that described display panel has, and the pin that is write down according to described blind spot detection chip is labeled in corresponding blind spot in the described distribution plan, for example, when detecting, described blind spot detection chip is numbered 2 pin current anomaly, the light emitting diode of described pin correspondence is in the 1st row the 2nd row, the light emitting diode of corresponding the 1st row the 2nd row on described distribution plan is noted as blind spot, so can make managerial personnel can find the position of blind spot very easily, simultaneously, if described blind spot display device remote computer, be that it is connected with described blind spot detection chip by network, like this, the scene that makes managerial personnel need not come to the display device place personally is especially detected, and has made things convenient for the long-range blind spot prosecution to display panel.
In sum, display system with blind spot measuring ability of the present utility model can realize the blind spot of the display panel is made up of the LED lamp is detected automatically by increase the blind spot detection chip in existing display system, and then by monitoring with realizing the long-range blind spot to display panel being connected of long-range blind spot display device.
