CN2807282Y - Optical display engine with high definition - Google Patents

Abstract

The utility model discloses an optical display engine with high definition, which relates to an improvement on a visual display device of a display. The optical display engine with high definition is characterized in that the transparent area of a color filter is provided with a reflector A of which the reflecting area is simultaneously provided with a collapsible lens A, a reflector B and a collapsible lens B, wherein the transparent area of the collapsible lens B is provided with a reflector C of which the reflecting area is provided with a screen. The optical display engine with high definition has the advantages that the color filter eliminates the phenomenon of polarization during incidence at 45 DEG, and the transparent effect of the entire optical engine is improved; the color filter replaces a spectroscopic color combining prism, so the cost of the optical manufacture is largely decreased, the color filter is suitable for mass production with high rate of finished products, and the optical performance and the rigid degree of a film layer satisfy the operating requirement; the utility model is especially suitable for the color separation and the color combination of the optical engine in digital projection televisions, and the accessory assembly and the cost of the entire optical engine are decreased simultaneously.

Description

High-resolution optics display engine

Technical field

The utility model belongs to household electrical appliance technical field, relates to a kind of improvement of display optics display device.

Background technology

At present, televisor is popularized, but the demonstration of televisor is because light is stronger, people's eyes are stimulated by high light for a long time, can cause eye fatigue, harm one's eyes, how to make televisor, projector picture light softer, become a problem that needs solve, late nineteen eighties, the appearance of rear-projection TV set, solved this problem, but what rear-projection TV set adopted is that x-cube filters, and as shown in Figure 1, it is the prism by four difference plated films, be bonded as one after grinding is flat, its deficiency is the cost height, adopts its optical filtering simultaneously, energy loss 50%.

Summary of the invention

The objective of the invention is:

A kind of sharpness height, production cost is low, the optical filtering energy loss is minimum high-resolution optics display engine are provided.

The technical solution of the utility model is:

Transmission area at colored filter is provided with catoptron A, and the echo area of catoptron A is provided with collapsible lens A, catoptron B, collapsible lens B simultaneously, and the transmission area of collapsible lens B is provided with catoptron C, and there is screen the echo area of catoptron C.

Colored filter is formed color-separation and color-recombination sheet group by blue color separation film and red color separation film, blue color separation film and red color separation film square crossing, and blue, red color separation film is to be substrate with K9 glass, is coated with zirconia and membranous layer of silicon oxide on the glass.

The beneficial effects of the utility model are:

Adopt colored filter, the polarization phenomena when having eliminated 45 jiaos of incidents has improved the translucent effect of overall optical engine.

Replace x-cube with this optical filter and significantly reduced the optics cost of processing, be suitable for producing in batches, finished product rate height, optical property and rete firmness satisfy request for utilization, be specially adapted to photo engine in the digital projection TV color separation, close look and use, also reduced the accessory combination and the cost of overall optical engine simultaneously.

Fig. 2 is the utility model structural drawing;

Wherein: the 1st, red laser, the 2nd, green laser, the 3rd, blue laser, the 4th, blue color separation film, the 5th, red color separation film, the 6th, catoptron A, the 7th, collapsible lens A, the 8th, catoptron B, the 9th, collapsible lens B, the 10th, catoptron C, the 11st, screen.

Embodiment

Below in conjunction with accompanying drawing the present invention is described further:

This colored filter records under 45 jiaos, and blue color separation film I transmission area wave band is 510nm-700nm, and transmitance T＞80%, mean transmissivity T are 85%; Echo area 440nm-500nm, reflectivity R＞98%.Red color separation film II transmission area wave band is 400nm-590nm, and transmitance T＞80%, mean transmissivity T are 85%; Echo area 600nm-670nm, reflectivity R＞98%.

Catoptron A, B, C at transmission area all by 45 jiaos of placements of light walking along the street line, collapsible lens A, B in the echo area all by 90 jiaos of placements of light walking along the street line.

Owing to adopt colored filter to filter, significantly reduced energy loss, make light more clear, soft simultaneously.
