Abstract

A naked-eye 3-dimensional LCD all-in-one machine is LCD equipment which is used for watching three-dimensional pictures without the aid of a pair of glasses. The all-in-one machine comprises an industrial control board, an external memory, an internal memory, a digital liquid crystal drive board, a high-voltage plate, a power supply plate, and an LCD display, wherein, the LCD display is divided into a slot grating tablet, light-transmitting medium, an astigmatism film, the LCD screen and a back-light plate; the grating textures of the slot grating tablet incline from the left upper part to the right lower part; an inclined angle Beta form 72.5-82.5 degrees is formed between the grating textures and the level; the grating pitch Alpha between two adjacent grating textures is less than or equal to 3cm; the adjustable distance between the slot grating tablet and the LCD is 2-5mm; and the light-transmitting medium in the middle is a toughened glass or air. The utility model has the advantages that firstly, the all-in-one machine can be hung on a wall, occupies less space, is simple to operate and convenient to maintain; secondly, all unattended type operable switches, which are built-in and can be locked, can be placed at various public occasions, thereby saving manual labour and material resources greatly; thirdly, the all-in-one machine can be externally connected with a mouse and a keyboard, so the system is convenient to maintain, and the all-in-one machine can be remotely controlled through the network interface on the all-in-one machine.

Description

A kind of bore hole 3D liquid crystal display all-in-one

Technical field

The utility model belongs to the electronic display technology field, and particularly a kind of not wearing glasses watched the liquid crystal display device of stereo-picture.

Background technology

At present, aspect social life many, all using electronic display unit, wherein the 3D LCD can improve the demonstration effect greatly, for example in the following areas: 1, the advertising of various public arenas.2, the building whole structure of real estate industry is showed.3, the solid show of museum's showpiece.4, the aircraft flight effect of military project scientific research department demonstration.5, the effect preview of static disparity picture in the relief painting industry.6,3D three-dimensional film, TV industry, or the like.And the liquid crystal display device of watching stereo-picture of not wearing glasses receives praises from customers owing to use conveniently.

Summary of the invention

The purpose of the utility model is to need not by other aid for people provide a kind of, and bore hole can reach the liquid crystal display all-in-one of 3D effect.

The technical scheme of the utility model is: this machine comprises industrial control board, external memory storage, internal storage, digital lcd drive plate, hardboard, power supply board and LCD display; Wherein LCD display is divided into 5 layers from the front panel to the rear board; Be respectively slit grating sheet, light transmission medium, light-diffusing film, LCDs and backlight; The grid line incline direction of slit grating sheet tilts to the lower right from the upper left side, and grid line and horizontal inclination angle beta are 72.5 ~ 82.5 °, the pitch α of adjacent two grid lines≤3cm; The distance of slit grating sheet and LCDs is that 2 ~ 5mm is adjustable, and middle light transmission medium is toughened glass or air.

The beneficial effect of the utility model: 1, can wall hanging, it is little, simple to operate, easy to maintenance to take up an area of the space.2, the whole built-in and lockables of all operable switches are suitable for being placed on various public arenas, belong to the unattended operation type, can save a large amount of manpower and materials.3, can external mouse and keyboard, system maintenance easy, the band network interface can pass through Long-distance Control.

Embodiment

With 42 cun liquid crystal display all-in-ones is example

One, the basic functional principle of this machine:

1, the assurance left eye is only seen left-eye image, and right eye is only seen eye image; Realize through the grating beam splitting technology.

2, generate eight width of cloth images in each scene at least, wherein four width of cloth just are equivalent to the image of people's left eye generation, and other four width of cloth just are equivalent to the image that right eye generates, and realize through signal processing unit.

Two, circuit hardware system

The formation of hardware system comprises industrial control board GPU (dual core processor), external memory storage M1, internal storage M2, power panel VCC, digital lcd drive plate D, hardboard HV, power board AMP, sound accompaniment loudspeaker SP and LCD display shown in accompanying drawing 1.Wherein LCD display is divided into 5 layers from the front panel to the rear board, is respectively slit grating sheet 5, light transmission medium 4, light-diffusing film 3, LCDs 2 and backlight 1.LCDs 2 requires to be necessary for the high-resolution screen, and physical resolution requires to reach 1920 * 1080, and the pure digi-tal formula that the is necessary for signal that liquid crystal drive plate D accepts and exports requires to reach fully point-to-point control and demonstration.

Three, the manufacture method of slit grating sheet

Shown in accompanying drawing 4; According to the point of the pixel of display apart from the width that can calculate each color dot; Per 3 pixels be one group pairing be 9 color dots, measure actual size with measuring instrument through pairing color dot behind the toughened glass, go to fill according to 7 black 2 white methods.Directly export lenticular lenses through the high accuracy printer.

Four, image input

8 width of cloth are synthesized the clear 3D rendering of a panel height through static images or the dynamic image of handling through fusion software; Directly import in the display and just can in people's eyes, form the image with difference through the light splitting technology of slit grating sheet, the fusion through brain just can make the people under the bore hole state, see stereoscopic three-dimensional image.The effect of light-diffusing film is exactly to eliminate the mole line that LCD display produced through the effect of astigmatism.
