Checkout equipment in order to the present embodiment is applied in reality, and testing result is more accurate, and preferably, described control module is used for making display device show the sprite of at least two kinds of primary colors in redness, green, blueness successively.Also just say that first control module can make display device show red picture, then carry out detection display equipment by above-mentioned collecting unit, comparing unit; Following control module shows green picture by making display device, come again to detection display equipment by above-mentioned collecting unit, comparing unit again, in like manner control module shows blue picture by making display device, certainly in order to save detection time, preferably control module makes display device show the sprite of two kinds of primary colors in redness, green, blueness successively.
The display apparatus detection device of the present embodiment can be used for the duty of detection display equipment, and its display device detected can be the display device of any known type such as liquid crystal display, organic light-emitting diode (OLED) display apparatus.
Preferably, above-mentioned display device is the display device being located at the public places such as bus, subway, high ferro, building, elevator.
As previously mentioned, more difficultly when breaking down with display device to be in public places found, therefore the display apparatus detection device of the present embodiment preferably detects with to these display devices.But obviously, detecting if should be appreciated that with the display device etc. of display apparatus detection device to family expenses of the present embodiment, is also feasible.
Above-mentioned control module shows predetermined content measurement for making display device, and it specifically can be ARM chip (as LPC1754 cake core), and ARM chip is simple, cost is low, and function can be satisfied the demand again, therefore is preferred.Of course it is to be understood that the object lesson of control module is not limited thereto, it also can be other forms such as programmable logic controller (PLC), microprocessor.
Simultaneously, above-mentioned ARM chip (control module) is except showing except content measurement for controlling display device, also reporting unit can be controlled simultaneously, and above-mentioned comparing function (namely also can be used as comparing unit) can be carried out, that is, multiple unit in the present embodiment can be separate on hardware, but also accessible site is integrated.
Preferably, control module is used for controlling display device when display device starting-up and shows predetermined content measurement; And content measurement is preferably the sprite of each primary colors of this display device.
Wherein, generally include in display device " sub-pixel " of multiple different colours, the combination of different colours sub-pixel can make display device demonstrate color required arbitrarily, and the kind of display device sub-pixel color, be namely called " primary colors " of this display device.Such as, to the display device of RGB pattern (RGB pattern), its primary colors is exactly red, green, blue, thus when it is started shooting at every turn, namely control module controls the Driver Card of this display device, makes display device show redness, green, blue trichromatic sprite (such as every width picture shows 1 second) successively.Certainly, for the display device of other patterns such as RGBY pattern (red, green, blue and yellow pattern), RGBW pattern (red, green, blue and white pattern), then can the yellow picture of corresponding increase, white picture etc. in its content measurement.
Why preferably show content measurement when starting shooting, be because test can be completed like this in the short time after powering and the Timeliness coverage fault that may exist, and in most time, all show normal content, therefore it is very little on the impact normally watched.
Certainly, if content measurement otherwise carry out showing also can, such as can be every the schedule time just display once, or for show when receiving particular command.
And why adopt the primary colors picture of display device as content measurement, be because if display device normally can show the picture of its each primary colors, then the probability gone wrong when it shows other pictures is very little, substantially can assert that it is working properly.
Of course it is to be understood that if adopt other pictures preset as content measurement, be also fine.
Above-mentioned collecting unit is for gathering the actual content shown by display device, and what picture what namely determine that display device really demonstrates is on earth.
Preferably, now collecting unit is color sensor; Preferred, color sensor is for gathering the Show Color at the bight place of the display surface of display device.
