The utility model has the advantages that the utility model raises the display quality and the entirety performance, so the electronic displaying screen has homogeneous entire display, good effect and tuneful image, overcoming the 'mosaic ' phenomenon; the qualification rate of the products is raised; the production cost is reduced; and the product is easy to be popularized.

Description

The electronic display of no vision difference

Technical field: the utility model relates to a kind of electronic display of not having the vision difference.

Background technology: electronic display is made of a plurality of semiconductor light emitting unit modules, the semiconductor light emitting unit module then is made up of a plurality of luminous point, at present, the method for making of the semiconductor light emitting unit module of electronic display, be that the luminescent wafer that wavelength is identical with brightness degree is placed on each luminous point in the same semiconductor light emitting unit module, because luminescent wafer is divided into a plurality of grades because of the error of wavelength and brightness, therefore, brightness in the same semiconductor light emitting unit module is identical, and the electronic display that is made of different semiconductor light emitting unit modules just has multiple different brightness.Its weak point is: owing to electronic display is made of the different semiconductor light emitting unit of multiple brightness, thereby the overall brightness of electronic display is inhomogeneous, the local luminance difference is very big, visually form " mosaic " phenomenon, qualification rate is low, the cost height.

Summary of the invention: the utility model mainly is to solve the inhomogeneity problem of overall brightness.The utility model comprises electronic control circuit and semiconductor light emitting unit module part, and semiconductor light emitting unit module 2 is that the luminescent wafer 1 by multiple different brightness degrees constitutes multiple different brightness degrees

Luminescent wafer 1 at random mixed distribution on each luminous point of semiconductor light emitting unit module 2.Semiconductor light emitting unit module 2 of the present utility model can be applicable to the electronic display of single primary colours, dual base color and full color.

The beneficial effects of the utility model are: 1, improve display quality and overall performance, make the integral body demonstration of electronic display even, respond well, image is more harmonious, and has thoroughly overcome " mosaic " phenomenon; 2, improve the qualification rate of integral product, qualification rate reaches more than 95%; 3, reduce production costs greatly; 4, be applicable to all electronic displays, easy to utilize.

Description of drawings:

Fig. 1 is a semiconductor light emitting unit module structural representation of the present utility model.

Among the figure: the 1st, luminescent wafer, the 2nd, the semiconductor light emitting unit module,

Be the different brightness degrees of luminescent wafer.

Embodiment: the utility model will be further described below in conjunction with accompanying drawing:

Referring to Fig. 1, the utility model is respectively brightness degree

Luminescent wafer 1 mixed distribution is on each luminous point of semiconductor light emitting unit module 2 at random, the mixing at random that causes luminescent wafer 1 to form multiple different brightness degrees on semiconductor light emitting unit module 2 is arranged.Owing in the semiconductor light emitting unit module 2 of electronic display many luminous points are arranged, distance is limited than the brightness of short and single luminescent wafer 1 between the adjacent luminous point, people's vision also fails the luminance difference of the luminescent wafer 1 of adjacent different brackets is distinguished, thereby the luminosity of each block semiconductor luminescence unit module 2 is with regard to nonrated branch, and has only a kind of brightness.And by these electronic displays that does not have the semiconductor light emitting unit module 2 of the branch of brightness degree to be constituted, between semiconductor light emitting unit module 2, do not exist " border " problem, just there is not inhomogeneous and " mosaic " phenomenon of demonstration visually on the whole yet, thereby the display quality and the overall performance of electronic display have been improved, make image more harmonious, display effect is better, and has improved the qualification rate of product and reduce production costs greatly.
