Description
Technical field
The present invention relates to a kind of optical tubes, especially one kind can be used in rangefinder, gun sight, magnifying glass, telescope,
The object that can be immediately seen outside object lens on microscope or view finder of camera, and can not can shown by what environmental light intensity was influenced
The optical frames with penetration crystal display of scheduled text or/and pattern is shown in display screen at least one color
Cylinder and application thereof.
Background technique
A kind of existing optical tubes, including lens barrel main body are equipped with eyepiece in one end of the lens barrel main body, in the lens barrel
The other end of main body is equipped with object lens, and the LCD or LED display of a penetration, the LCD display are equipped in focal plane position
User is allowed to be immediately seen the object outside object lens through object lens from eyepiece, meanwhile, the LCD display can also be driven with LCD
Under the control of device, preset text or/and pattern are shown.
Currently, used LCD display is mainly the following in existing optical tubes, the first is that TN is shown
Screen, this display screen light transmittance is lower, and cannot use when ambient light is dark；Second is high light transmission formula liquid crystal display,
This display screen light transmittance is high, can achieve 90%, still, as TN display screen, cannot use when ambient light is dark；The
Three kinds are modified high light transmission formula liquid crystal displays, it is in the small side perpendicular with display surface of high light transmission formula liquid crystal display
A monochromatic LED lamp, such as red, green or blue is arranged in face, and in dark, opening monochromatic LED lamp can show on a display screen
, but text or/and pattern that light intensity different consistent with the color of LED light, still, this modified high light transmission formula liquid crystal are shown
The background colour of display screen and the color of LED light are identical, and text or/and pattern is on the one hand made to become smaller with background colour color difference, influence
The reading of user reduces the light transmittance of display screen on the other hand due to the presence of coloured background colour；In addition to LCD screen,
Separately there is a kind of active illuminant display screen also to have to be used, such as LED and OLED, since OLED display screen is self luminous display
Screen preferably solves the problems, such as that existing display screen is non-serviceable when environment is half-light, still, due to OLED display screen itself
It is illuminator, if external environment light is very strong, the brightness of OLED display screen will be offset by the brightness of external environment, this
In the case of kind, there are problems that text or/and pattern are not easy to see clearly；And high saturating LCD is far not achieved in its display screen transmitance
Level, in addition, expensive due to OLED display screen, in this way, the price of the optical tubes with OLED display screen nor
Chang Gui is only used for high price market.A kind of light transmittance height is needed in the market, and the background of LCD display is colorless and transparent or connects
It is close colorless and transparent, and not by the optical tubes that external environment light power is influenced and cost performance is high.
Summary of the invention
In order to overcome the above problem, the present invention provides a kind of light transmittance height, and the background of LCD display is colorless and transparent or connects
The nearly optical tubes and its use with penetration crystal display that be colorless and transparent, and not influenced by external environment light power
On the way.
The technical scheme is that providing a kind of optical tubes with penetration crystal display, including lens barrel
Main body is equipped with eyepiece in one end of the lens barrel main body, object lens is equipped in the other end of the lens barrel main body, in optical frames
The focal plane position of cylinder is equipped with LCD display, and the visible area of the LCD display allows user to penetrate object lens from eyepiece
The object being immediately seen outside lens barrel main body, meanwhile, the LCD display shown under the control of LCD driver text or/and
Pattern, the LCD display are light scattering formula LCD displays, and visible light source, the light are additionally provided in the optical tubes
The position in source will meet: being arranged in except the visible area of light scattering formula LCD display, be located at light scattering formula LCD display
Front side or/and rear side, and the maximum incident angle of the light of light source selects between more than or equal to 30 degree less than 90 degree and light source
Incident ray or reflection light to avoid being directly incident in eyepiece visible area.
As improvement of the present invention, the light source is the single light source of one of red, green and blue, or by red, green and blue
In any dichromatism or three colors composed by mixed-color light.
As improvement of the present invention, the light source is LED light source.

In the visible area of screen.
As improvement of the present invention, the light source is at least one point light source, and each point light source is independently located at
Light scatters on the inner wall between formula LCD display and eyepiece, and the light oblique fire that the point light source issues is shown in light scattering formula LCD
In the visible area of screen.
As improvement of the present invention, the light source is multiple point light sources, and all point light sources are located at an annular panel
On medial surface, the annular panel is located on the inner wall between light scattering formula LCD display and object lens, what the point light source issued
Light oblique fire is in the visible area of light scattering formula LCD display.
As improvement of the present invention, the light source is multiple point light sources, and all point light sources are located at an annular panel
On medial surface, the annular panel is located on the inner wall between light scattering formula LCD display and eyepiece, what the point light source issued
Light oblique fire is in the visible area of light scattering formula LCD display.
As improvement of the present invention, the light source is area source, and the area source includes uniform light board, in the uniform light board
The through-hole for the area for being equal to or more than the visible area equipped with one is equipped at least one point light on the side of the uniform light board
