Description

A kind of ultra high-definition LED display

Technical field

The utility model relates to the LED display field, specifically refers to a kind of ultra high-definition LED display.

Background technology

Along with the develop rapidly of LED technology, the LED display application is more and more extensive, for example various megastore, hotel, place of public amusement etc.At present the LED display high density mostly between P3(two pixels apart from 3mm) left and right, closely watching (such as 1 meter distance) is not also to meet very much the ultra high-definition scheme, can see obvious granular sensation.Described LED display P3 density is mainly to be subject to LED lamp encapsulation specification limits, and in conventional art, the LED lamp can't be accomplished little encapsulation specifications design, and usually adopting the encapsulation specification is the i.e. wide 20*20mm of being of long * of 2020() or larger.And, along with technology constantly advances, the appearance of little packaged LED lamp provides advantage for the design of LED display ultra high-definition.Have, traditional die drives and often adopts conventional constant current control chip again, and the constant current control performance is limited.In the display image procedure for displaying, also often there will be smear to show phenomenon, have a strong impact on the sharpness of image.

The utility model content

The purpose of this utility model is to provide a kind of ultra high-definition LED display, by super-high density design, high-accuracy and constant current control and control electric current blanking problem, realize the ultra high-definition image display effect.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of ultra high-definition LED display, comprise LED display, LED Drive and Control Circuit, LED blanking control circuit and power supply; Described LED display adopts little encapsulation specification LED lamp, and between these adjacent two LED lamps, spacing is 1.9mm; This LED Drive and Control Circuit and described LED display are electrically connected; The signal input part of described LED blanking control circuit is electrically connected to the signal output part of described LED Drive and Control Circuit, and the control output end of this LED blanking control circuit and described LED display are electrically connected.

The three-in-one full-color LED lamp that the encapsulation specification that described little encapsulation specification LED lamp is the QFN encapsulation is 0.5mm*0.5mm.

After adopting such scheme, this Novel photo is for the beneficial effect of prior art: display screen adopts little encapsulation specification LED lamp, and display screen density reaches P1.9.Preferably adopt high precision LED constant current chip (such as chip MBI5041) in the LED Drive and Control Circuit that control LED display image shows, every monolithic chip can be controlled 128 RGB lamps, number of devices used is significantly reduced, and each LED lamp is realized to accurate constant current control.The image of LED display shows that smear problem is effectively solved by the LED blanking control circuit, reaches the high ash of high brush without the ghost effect.This novel LED display that is configured to a kind of super-high density, really reaches ultra high-definition thus, this display screen can also know at 1 meter the pattern of seeing on display screen, by ultra high-definition ratio (screen proportion) 16:9 distribution, more than Show Color reaches 16.7M.

Embodiment

Below in conjunction with the drawings and specific embodiments to originally being described in further detail.

This case relates to a kind of ultra high-definition LED display, as shown in Figure 1-2, comprisesLED display 1, LED Drive and Control Circuit 2, LEDblanking control circuit 3 and power supply 4.Power supply 4 is whole display screen system power supply.

LED display 1 as shown in Figure 2, adopts little encapsulationspecification LED lamp 11, and between these adjacent two LED lamps, spacing is 1.9mm (being P1.9).Little encapsulationspecification LED lamp 11 is preferably the three-in-one full-color LED lamp of the little encapsulation specification of QFN encapsulation, adopts the quick paster of full-automatic chip mounter during assembling.Little encapsulation specification is better is controlled at long 0.5-1.5mm, wide 0.5-1.5mm, preferably the spacing between the close end of specification 0.5mm*0.5mm(two LED lamps as adjacent as Fig. 2 is 1.4mm).

The interior employing high precision of described LED Drive and Control Circuit 2 LED constant current chip (such as chip MBI5041), the control output end of LED Drive and Control Circuit 2 andLED display 1 are electrically connected.Every monolithic chip can be controlled three colors of 128 RGB lamps, and number of devices used is significantly reduced, and each LED lamp is realized to accurate constant current control.The signal input part of described LEDblanking control circuit 3 is electrically connected to the signal output part of LED Drive and Control Circuit 2, and the control output end of this LEDblanking control circuit 3 andLED display 1 are electrically connected.After the signal input part of LEDblanking control circuit 3 receives the signal of LED Drive and Control Circuit 2, control the capable signal of the LED chip ofLED display 1 via control output end, the stray capacitance that each row is caused to smear is charged, the image that effectively solvesLED display 1 with this shows smear problem, reaches the high ash of high brush without the ghost effect.Adopt a kind of HDMI/DVI dual input ultra high-definition LED display single deck tape-recorder netting twine control system in connection, significantly promoted bandwidth, function and the cost performance of traditional LED display controller.The circuit structure of described LEDblanking control circuit 3 has various ways, and is known technology, in this, does not launch to set forth.

To sum up, this novel LED display that is configured to a kind of super-high density, really reaches ultra high-definition, this display screen can also know at 1 meter the pattern of seeing on display screen, in ultra high-definition ratio (screen proportion) 16:9, distributes, more than Show Color 16.7M.Concrete advantage following points:

One, dot spacing is 1.9mm, really realizes high density, ultra high-definition;

Two, color is true to nature, and reduction degree is good, and brightness is high, and color is very gorgeous, with respect to LCD display, qualitative leap has been arranged;

Three, can be used in indoor much occasions, even can use as high definition home theater TV, can also be used as 3D and show;

Four, volume is little, ultra-thin, with respect to LCD, wants thin a lot, can combination in any length and width;

Five, maintenance only needs the removable parts part, fundamentally reduce expenses, and electricity consumption is little, and real environmental protection.

Above are only this novel preferred embodiment, all equalizations of doing with this novel claim scope change and modify, and all should belong to the scope of this novel claim.
