Abstract
The visual angle detecting device of display screen, the universal wheel of the swing arm being rotatably connected including protractor, with protractor straight flange midpoint, the pallet of swing arm end set and tray bottom setting, the swing arm are rotatably connected with protractor by shaft.The utility model provides a kind of visual angle detecting device of display screen, is relatively fixed test position, instrument and tested display screen, and mobile radius remains unchanged.Intuitive and convenient, it is easy to operate.
Description
Technical field
The utility model belongs to display screen detection device field, and in particular to a kind of visual angle detecting device of display screen.
Background technology
At present to the measurement of display screen angle of visibility, the distance between luminance meter and display screen are measured first with ruler,
Then angle is calculated.It is affected by human factors, instrument is in moving process, it is impossible to keep radius constant, instrument and display screen
Relative angle also change correspondingly, and the position of 1/2 point of central point test brightness is difficult to control.
Invention content
In view of the above-mentioned problems, the utility model provides a kind of visual angle detecting device of display screen.
To solve the above problems, the technical solution adopted in the utility model is：The visual angle detecting device of display screen, including amount
Angle device, the swing arm being rotatably connected with protractor straight flange midpoint, the pallet of swing arm end set and tray bottom are set universal
Wheel is provided with graduation mark on the round edge of protractor, can place measuring instrument on pallet, and pallet is radius along protractor using swing arm
Round edge moves, universal wheel can way moving to measure left and right visual angle.
The swing arm is rotatably connected with protractor by shaft, and swing arm rotation is smooth, is not in Caton phenomenon.
The utility model provides a kind of visual angle detecting device of display screen, makes test position, instrument and tested display screen
It is relatively fixed, mobile radius remains unchanged.Intuitive and convenient, it is easy to operate.

Fig. 2 is side view.
Wherein, 1, protractor, 2, straight flange, 3, shaft, 4, swing arm, 5, pallet, 6, universal wheel, 7, round edge.
Specific embodiment
As described in Figure, the visual angle detecting device of display screen is rotatably connected including protractor 1, with 1 straight flange midpoint of protractor
The universal wheel 6 of swing arm 4, the pallet 5 of 4 end set of swing arm and the setting of 5 bottom of pallet, is provided on the round edge 7 of protractor 1
Graduation mark can place measuring instrument, such as luminance meter on pallet 5, and pallet 5 is moved with swing arm 4 for radius along the round edge 7 of protractor 1,
Universal wheel 6 can way moving to measure left and right visual angle.
The swing arm 4 is rotatably connected with protractor 1 by shaft 3, and swing arm 4 rotates smooth, is not in Caton phenomenon.
Luminance meter is placed on the pallet 5 of detection device, when luminance meter is vertical with display screen, measures maximum brightness
Value, mobile pallet 5, luminance meter also moves, and when luminance meter show value is decreased to the 1/2 of maximum value, stops movement, according to
Graduation mark reading angular, direct reading, intuitive and convenient can move left and right addition after pallet 5 measures respectively and obtain angle of visibility, if
It meets the requirements of the standard, can determine that without angle calculation.
