Abstract

The utility model provides an LED and a display screen, which are applicable to the field of display. The LED comprises a line layer, a plurality of LED chips and a rubber mass, wherein the LED chips are fixedly arranged on the line layer, the rubber mass is used for wrapping the LED chips, and the periphery of the rubber mass is provided with a black frame so that the LED chips are not easily affected by environmental lighting and achieve high brightness, high contrast ratio and fine display effect. Similarly, the display screen made of the LED is fine in display effect.

Description

A kind of LED and display screen

Technical field

The utility model belongs to the demonstration field, relates in particular to a kind of LED and display screen.

Background technology

LED (Light Emitting Diode, light-emitting diode) is a kind of solid-state semiconductor lighting device, and it adopts electroluminescence, can directly be converted into light to electricity, is different from the luminous and luminous principle of electricity-saving lamp tricolor powder of incandescent lamp tungsten filament.Thereby the advantage of LED is very outstanding, and the life-span is long, light efficiency is high, radiationless and low-power consumption.

The spectrum of LED almost all concentrates on visible light frequency band, and LED can utilize the red, green, blue principle of three primary colours, makes every kind of color have 256 grades of gray scales under computer technology control.These three kinds of primary colours mix arbitrarily, can produce 256 * 256 * 256=16777216 kind color, form different photochromic combinations, realize colourful dynamic change effect and various image.

In view of intrinsic advantage, existing at present a large amount of LED are applied to display screen.But existing the demonstration with LED is subject to the ambient lighting influence, and display effect is poor.

The utility model content

The purpose of the utility model embodiment is to provide a kind of LED, is intended to solve existing LED and is subject to ambient lighting influence, the problem of display effect difference.

The utility model embodiment is achieved in that a kind of LED, comprises line layer, is fixedly arranged on a plurality of LED wafers of described line layer and the colloid that is used to coat described a plurality of LED wafers, and the periphery of described colloid is provided with dark border.

Another purpose of the utility model embodiment is to provide a kind of display screen, and described display screen adopts above-mentioned LED.

The utility model embodiment is provided with dark border in the periphery of colloid, makes LED not be subject to the ambient lighting influence, reaches high brightness, high-contrast, and display effect is good.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

The utility model embodiment is provided with dark border by moulding technology in the periphery of colloid, and the light that LED is sent is not subject to the ambient lighting influence, reaches high brightness, high-contrast, and display effect is good.

The LED that the utility model embodiment provides comprises line layer, is fixedly arranged on a plurality of LED wafers of described line layer and the colloid that is used to coat described a plurality of LED wafers, and the periphery of described colloid is provided with dark border.

The display screen that the utility model embodiment provides adopts above-mentioned LED.

Below in conjunction with specific embodiment realization of the present utility model is described in detail.

As depicted in figs. 1 and 2, the LED that the utility model embodiment provides comprises line layer 1, is fixedly arranged on a plurality of LED wafers of this line layer 1 and the colloid 2 that is used to coat these a plurality of LED wafers, and wherein the periphery of colloid 2 is provided with dark border.LED can not be subject to the ambient lighting influence like this, reaches high brightness, high-contrast, and display effect is good.

Usually, colloid 2 constitutes by the lower floor's colloid 22 that coats a plurality of LED wafers with the upper strata colloid 24 of these lower floor's colloid 22 Joints.Wherein lower floor's colloid 22 has a boss 23, and dark border is the upper strata colloid 24 that cooperates Joint with boss 23.

In addition, colloid 2 also can be made of inner lane colloid 25 that coats a plurality of LED wafers and the outer ring colloid 26 that cooperates with inner lane colloid 25, and wherein dark border is an outer ring colloid 26, as shown in Figure 3.

As preferably, above-mentioned lower floor colloid 22 or inner lane colloid 25 be for making the vaporific diffusion colloid of emitting uniform, and will there be stray light in the light that sends of LED like this.

Among the utility model embodiment, a plurality of LED wafers become in-line to arrange.Particularly, this LED comprises a red-light LED wafer 31, a blue-ray LED wafer 33 and is positioned at red-light LED wafer 31 and the green light LED wafer 32 of 33 of blue-ray LED wafers.The light that this arrangement mode sends each LED wafer has bigger overlapped zone, bright dipping after colloid 2 mixes, and bright dipping is more even, guarantees not have stray light and has the definition height.

The general long 0.05～0.06inch of this LED, wide 0.05～0.06inch, high 0.03～0.04inch, overall dimension is less, the spacing of adjacent LED also can reduce on the display screen, spacing as adjacent LED is 2.5～3mm or 3.5～4mm, thereby realizes close distance design, reaches the video display effect of homogeneous and higher color fidelity.

The utility model embodiment is provided with dark border in the periphery of colloid, makes LED not be subject to the ambient lighting influence, reaches high brightness, high-contrast, and display effect is good.Simultaneously, lower floor's colloid or inner lane colloid adopt vaporific diffusion colloid, thereby the light that LED is sent does not have stray light.In addition, make a plurality of LED wafers be arranged in in-line, the light that each LED wafer sends has bigger overlapped zone, and bright dipping after colloid mixes is guaranteed not have stray light and had the definition height.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
