No matter diode blue light-emitting with LED makes monochromatic, double-colored or three color screens, and image to be shown needs to constitute each LED's of pixel
Light emission luminance must be all adjustable, and the fine degree adjusted is exactly the tonal gradation of display screen, and tonal gradation is higher, display
Image is finer and smoother, and color is also abundanter, and corresponding display control program is also more complicated, the image of general 256 grades of gray scales, color
Transition is very soft, and the color image of 16 grades of gray scales, color transition boundary line are fairly obvious, so, color LED screen is currently all
It is required that be made into 256 grades to 4096 grades gray scales, have the advantage that 1), area ductility, LCD area is big to be difficult to realize
Seamless spliced, LED display can arbitrarily extend, and realize seamless spliced；2), LCD PDP display luminous flux attenuation quickly, generally
Run the time or so a year and a half, it is necessary to replace, but under the same service condition of LED display at least 5 years it is out of question；3), LED
Brush screen machine can use interaction technique, enhancing brush screen machine be used as interacting between advertising media and commercial audience, such as customization touch screen,
Realize cloud Broadcast Control management etc., wherein LED brush screen machine is generally used for airport, market, hotel, high-speed rail, subway, movie theatre, exhibition
Meeting, office building etc., target customer's consuming capacity is strong, has huge advertisement value；4), in terms of display effect, LED display
High brightness, wider viewing angle and good color restoration capability also superior to LCD screen.
In Grand LED Screen application field, the big screen LED screen of monolith is usually put together by multiple small LED screens,
And small LED screen usually requires to be installed with cabinet, however, being currently used for the generally existing structural strength of cabinet of installation LED screen
It is insufficient, be easily deformed, the technical problems such as box sizes error is excessive, seriously affect the total quality of LED display, for this purpose, I
Propose LED magnesium alloy pressure-casting case.
