Description
Technical field
The present invention relates to LED and show field, in particular to a kind of display screen and mosaic screen.
Background technology
At present, the pixel center of Small Distance LED display is apart from being less than 1 millimeter, less pel spacing, resolution higher under bringing identical display area, such as, pixel center has reached 1280*720 (720p) high definition resolution apart from 54 inches of Small Distance LED display units for 0.9mm.Meanwhile, Duo Jia LED manufacturer has also released one after another 27 inch, 50 inch, 55 inch and more how standard-sized Small Distance LED display unit.From the appearance, current Small Distance LED display unit similarly is more a LCD liquid crystal display splicing wall display.
As everyone knows, the procedure for displaying of LED display is by sending card/LED controller, receiving card, scanning board driving LED lamp plate display image.Sending card/LED controller is digital signal processing appts, also be the hardcore of driving LED display screen imaging, it can realize front end DVI/HDMI digital signal and access and be converted to the signal (normally carrying out signal conversion according to the self-defining agreement of each producer) that LED display can normally receive and be transferred to LED display end, as shown in Figure 1.
As can be seen from Figure 1, sending card/LED controller is still external device, needs to transfer signals to screen body end by cable.In addition, sending card/LED controller does not carry out convergent-divergent process to signal, but by front end complete image Signal transmissions to LED display end, received by receiving card, and by the scanning board in each display unit, complete signal is accurate to the region display of pixel, with the physical resolution of each LED display unit corresponding.
LCD liquid crystal display splicing wall display is different from LED display on signal transacting with application mode, as shown in Figure 2, the general built-in high-performance treatments plate of LCD liquid crystal display splicing wall display, possesses multiple digital and analog signaling interface, such as, the interface such as DVI, HDMI, DP, VGA, YPbPr, AV; There is OSD (i.e. screen menu type regulative mode, full name is On-ScreenDisplay,) menu, as shown in Figure 3, can use a teleswitch, keypad operation, mode of operation and conventional television are consistent, and such as, are switched the signal source, adjusting screen brightness etc. of input by remote controller; Possesses signal convergent-divergent processing capacity, the different resolution signal transacting that front end can be inputted is that the whole screen display of whole display is shown, Huo Jiang mono-tunnel signal source shows this road signal by the display that the whole mosaic screen of daisy-chain fashion articulating is all simultaneously, and can by built-in wall function using this road signal as a width complete image in whole splicing screen display, as shown in Figure 4.In addition, LCD liquid crystal display splicing wall display is without the need to sending card/LED controller external as LED display, and industrial integrated level is high, and front end signal directly docks with display the corresponding interface, and system building is simpler.
Although standardization Small Distance LED display unit of the prior art exists, and sending card/LED controller is built into display unit inside, casing exposes the DVI/HDMI interface of sending card/LED controller, front-end digital signal output equipment directly can dock with LED display unit, in product design and external signal transmission, reach unanimity with LCD liquid crystal display splicing wall display, as shown in Figure 5, but still adopting traditional LED display type of drive of sending card/LED controller+receiving card, there is following shortcoming in existing standardization Small Distance LED display unit:
1) signal transacting is single, and do not possess multiple digital and analog signaling disposal ability, corresponding interface is single, only has DVI or HDMI digital interface, does not possess abundant digital and analog interface, such as: the interfaces such as DVI, HDMI, VGA, YPbPr, AV;
2) signal transacting does not possess zoom capabilities, can not carry out convergent-divergent process, thus realize the requirement of whole display unit whole screen display Shi Gai road signal source to the different resolution signal source of front end input;
3) signal transacting form is single, a road signal source can not be passed through all display units of the whole mosaic screen of daisy-chain fashion articulating; Do not have " wall function " yet, can not using a road signal as a width complete image in whole splicing screen display.
To sum up, although current Small Distance LED display unit has met the display size of standard profile.But, from signal transacting, enrich the aspect such as interface, application mode, also there is different with LCD liquid crystal display splicing wall display.
For the problem that LED display unit signal transacting in correlation technique is single, at present effective solution is not yet proposed.
