Abstract
The utility model discloses a kind of display with automatic dimming function, it is the military very color high brightness TFT liquid crystal panel of setting-in one in a reinforcement type body, there is a sensitive probe on the upper left side of described liquid crystal panel, the described body back side is top is equipped with an OSD adjustment panel, and left surface is configured with a public air plug interface of VGA and DC28V power supply on the lower.Described body aluminium alloy panel surrounding has been uniformly distributed 12 mounting holes.When the upper left sensitive probe of display liquid crystal panel perceives the change of extraneous light, the photoresistance resistance in display internal circuit board 5766 changes thereupon, causes the change of internal circuit board 5766 output current value, thus changes the brightness of display screen.The regulating effect that when indicator screen when extraneous light grow brightens, extraneous light dies down, indicator screen is dimmed can be realized thus.
Description
Technical field
The utility model relates to a kind of display product, relates to a kind of display with an automatic light meter in particular.
Background technology
At present, known indicator screen display parameter (as screen intensity, contrast etc.) are all by arranging display properties in an operating system, or are adjusted screen display parameters by the function button that display is external.But for the industrial display of applied environment situation complexity, external environment variation range is large, and change frequency is high, especially when light is flickering, if only rely on manual adjustments, then add the operating personnel's extra work amount using display, nor convenient; If do not go to adjust display parameter, display effect is undesirable again.
Summary of the invention
The purpose of this utility model is the weak point overcoming above-mentioned existing background technology, and provides a kind of display with an automatic light meter.Technical purpose of the present utility model is achieved by the following technical solution.Display with an automatic light meter, include reinforcement type body, it is characterized in that: it also comprises a military very color high brightness TFT liquid crystal panel, there is an inductive probe on the upper left side of described liquid crystal panel, the described body back side is top is equipped with an OSD adjustment panel, and left surface is configured with a public air plug interface of VGA and DC28V power supply on the lower.Described body aluminium alloy panel surrounding has been uniformly distributed 12 mounting holes.The utility model tool has the following advantages: when the upper left sensitive probe of display liquid crystal panel perceives the change of extraneous light, photoresistance resistance in display internal circuit board 5766 changes thereupon, cause the change of internal circuit board 5766 output current value, thus change the brightness of display screen.The regulating effect that when indicator screen when extraneous light grow brightens, extraneous light dies down, indicator screen is dimmed can be realized thus.
Accompanying drawing explanation
Fig. 1,2,3 is the structural representation of the utility model display with an automatic light meter, and Fig. 4 is adjustment process schematic diagram of the present utility model.In Fig. 4: 3 sensitive probes, 11 photoresistance, 12 circuit board 5766,13 displays.
Embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not form to restriction of the present utility model, only for example.Simultaneously by illustrate, advantage of the present utility model by become clearly and easy understand.Accompanying drawings is known: display with an automatic light meter, include reinforcement type body 1, it is characterized in that: it also comprises a military very color high brightness TFT liquid crystal panel 2, there is a sensitive probe 3 on the upper left side of described liquid crystal panel 2, described body 1 back side is top is equipped with an OSD adjustment panel 4, and left surface is configured with a public air plug interface 5 of VGA and DC28V power supply on the lower.Described body 1 aluminium alloy panel surrounding has been uniformly distributed 12 mounting holes 6.In the embodiment shown in Figure 2, display with an automatic light meter is steadily positioned over a certain platform, connect air plug interface 5 switch on power and display and main frame are interconnected, be convenient to the transmission of data, the ON/OFF touched on OSD adjustment panel 4 presses switch to open display with an automatic light meter.Use this display first, whether manually should operate body 1 back side OSD regulates the AUTO key detection display device resolution on panel 4 correct, and automatically adjust Image display position, if also need to regulate brightness, colour temperature, contrast just to press MENU Menu key, select the option needing to regulate, increase by operation LEFT, RIGHT key and reduce parameter value, making display present best display effect.In the embodiment shown in Figure 4, the change of the automatic testing environment light intensity of the upper left sensitive probe 3 of liquid crystal panel 2, if light grow, photoresistance 11 resistance in display internal circuit board 5766 is then caused to reduce, make the power input of power amplifier become large, then output power also becomes large, when signal output part fixed resistance resistance is constant, output current becomes large, thus display screen is brightened; If light dies down, then cause photoresistance 11 resistance in display internal circuit board 5766 to increase, the power input of power amplifier is diminished, then output power also diminishes, when signal output part fixed resistance resistance is constant, output current diminishes, thus makes display screen dimmed; Realize the regulating effect that when indicator screen when extraneous light grow brightens, extraneous light dies down, indicator screen is dimmed thus.Other unaccounted part is prior art.
Claims (2)
1. a display with an automatic light meter, include reinforcement type body, it is characterized in that: further comprising a military very color high brightness TFT liquid crystal panel, there is an inductive probe on the upper left side of described liquid crystal panel, the back side is top is equipped with an OSD adjustment panel, and left surface is configured with a public air plug interface of VGA and DC28V power supply on the lower.
2. display with an automatic light meter according to claim 1, is characterized in that body aluminium alloy panel surrounding has been uniformly distributed 12 mounting holes.
