Abstract
The invention provides a single chip liquid crystal projector, which comprises a liquid crystal screen and an adjusting mechanism, wherein the adjusting mechanism is used for adjusting the rotation angle of the liquid crystal screen. By the adjusting mechanism, the rotation angle of the liquid crystal screen which rotates around the vertical central axis or/and the horizontal central axis of the liquid crystal screen is adjusted, so that the liquid crystal screen is parallel to the surface of the screen. Regardless of the installation position of the crystal projector in a room, the liquid crystal screen is parallel to the surface of the screen, so that clear focusing of the screen is ensured. By the single chip liquid crystal projector, the problem of unclear focusing of the screen caused by insufficient pitching angle under the condition that the single chip liquid crystal projector is hung close to a ceiling in the prior art is solved.
Description
Technical field
The present invention relates to a kind of little apparent projection field, relate in particular to a kind of single chip liquid crystal projector.
Background technology
According to optical principle, when the plane of projector and screen becomes standard 90 degree, could focus on clearly, otherwise top focusing known, below unclear, perhaps opposite, in like manner left and right directions also is.In fact all there is such deficiency in any projector, comprises the three-chip type liquid crystal projector of import, DLP projector etc., just import projector face upward very big, so largely alleviated the contradiction that exposes self deficiency.
Less than normal if face upward, so when installing, normally watch in order to guarantee that focusing is clear, just can only lean on projector as far as possible on the perpendicular bisector of screen, if projection 100inch, the screen height overall is 2 meters, the size of splitting up and down is 1 meter, if screen is not to place by floor or ceiling, that projector will be suspended in mid air, and perhaps needs to be placed on the very high platform.In fact screen can not below against the floor or above adjacent ceiling because, have no idea to watch for a long time at all like that to a normal person.
Our country, most indoor room finishings back free height is generally at 2.5～3 meters, screen center is generally apart from ground about 1.5, if projector is installed in the place apart from 1.5 meters on ground, no matter be on lifting or the platform of placing, not only hinder to be positioned at the people who sends out after the projector and to watch, and any family all is difficult to accept such layout and family's aesthetic feeling of causing is destroyed, also causes in the life walking through settling the inconvenience in projector zone.Usually, no matter how how curtain is installed, and all needs projector to paste the ceiling lifting as far as possible.Not enough if face upward, just need projector on screen, to throw at a slant, will occur focusing on clearly root problem this moment.And to realize such mounting means, and have only projector to tilt to throw, could realize.But the consequence that tilts is exactly as previously mentioned, can only focus on clear a part of picture, such as top clear, below unclear phenomenon.
This technology has been a blank out since projector's product came out for more than halfth century always.And all slip-stick artists and research staff in the industry, all design philosophy is concentrated on and how to go to increase in the off-axis design, Z700 type home projector such as Sanyo, remain the off-axis mode of use, its camera lens can level move with vertical off-axis, is respectively level 100%, vertically 150%(promptly is equivalent to face upward 150%), obviously, can satisfy the room installation requirement in any practicality, its liquid crystal display size 0.74inch.For the one chip projector of 5inch, so big off-axis design is impossible, because the manufacturing of camera lens has exceeded present manufacturing highest level.
Summary of the invention
The purpose of this invention is to provide a kind of energy and guarantee that whole screen focus on clearly single chip liquid crystal projector.
This single chip liquid crystal provided by the invention projector, comprise liquid crystal display, also comprise the governor motion that is used to regulate the liquid crystal display anglec of rotation, this governor motion make liquid crystal display around self vertical central axis or/and after the horizontal center line axis corner regulates, guarantee that this liquid crystal display is parallel with the face of projection screen.
Described liquid crystal display is installed in the housing, and described governor motion adopts one, is used to regulate liquid crystal display around himself horizontal center line axis rotational angle.
Described liquid crystal display is installed in the housing, and described governor motion has two, and one is used to regulate liquid crystal display along himself vertical central axis rotation, and another is used to regulate liquid crystal display and rotates along its horizontal center line axis.
Described governor motion comprises the adjusting handle of a sector gear and a band worm screw, worm screw on the adjusting handle and the engagement of described sector gear, and this sector gear is fixedly mounted on the described housing.
The present invention is owing to be provided with governor motion in existing single chip liquid crystal projector, we can regulate especially tilt angle of the orientation of liquid crystal display and inclination angle by this governor motion, where make room that no matter projector install, can both guarantee that liquid crystal display parallels with the face of screen, thereby it is clear to have guaranteed that screen focuses on.Solved in the prior art single chip liquid crystal projector under the situation of being close to the ceiling lifting, tilt angle is not enough and cause screen to focus on unclear problem.
Description of drawings
Fig. 1 is the structural representation front view of one embodiment of the present invention.
Fig. 2 is the left view at Fig. 1.
Embodiment
From Fig. 1 and Fig. 2 as can be seen, the present invention still comprises liquid crystal display 1, also comprise governor motion 2, liquid crystal display 1 is installed on the housing 3, governor motion 2 can adopt any governor motion in the existing machinery appliance field, as long as can make liquid crystal display 1 around himself horizontal center line axis and/or vertical central axis adjustment corner, liquid crystal display is got final product with the face of projection screen is parallel.What governor motion adopted in the present embodiment is that gear rotates governor motion, this governor motion comprises the adjusting handle 5 of a sector gear 4 and a band worm screw, worm screw on this adjusting handle and sector gear 4 engagements, sector gear 4 is fixedly mounted on the housing 3, is positioned at the position of housing horizontal center line axis.By rotation adjusting handle 5, the inclination angle that makes sector drive liquid crystal display changes, and the sense of rotation of adjusting handle has determined the change direction at the elevation angle, can regulate as the case may be during use, parallel with the face of screen up to liquid crystal display, screen focuses on clear getting final product.The orientation of liquid crystal display also is to need to regulate to guarantee that its face with screen is parallel under some special situations.Can install a governor motion again this moment in the position of the vertical central axis of liquid crystal display, and liquid crystal display is rotated around its vertical central axis, the orientation takes place change, parallel with the face of screen until liquid crystal display.
