IPS screens rest area can be put into well, IPS screens can be tested by opening backlight, can meet the test of different size IPS screens,
It reduces different size model number back lighting devices and exchanges wasted working hour back and forth.
Description of the drawings
Fig. 1 is the structural schematic diagram of test backlight case after a kind of IPS screens patch proposed by the present invention.
Specific implementation mode
As shown in FIG. 1, FIG. 1 is the structural schematic diagrams of test backlight case after a kind of IPS screens patch proposed by the present invention.
Referring to Fig.1, test backlight case after a kind of IPS screens patch proposed by the present invention, including babinet 1, backlight, be in the light
Plate 3；Backlight is mounted on inside babinet 1, and the setting of 1 upper angled of babinet, angle with horizontal plane is 30 °, and 1 top of babinet offers
Light hole, light hole is rectangular, and the luminescent layer 2 of backlight is located in light hole, and 1 upper edge luminescent layer of babinet is equipped with limit in 2 one weeks
Position frame 4, limitting casing 4 is also rectangular, and limitting casing 4 protrudes the luminescent layer 2 of backlight, and limitting casing 4 is embedded with transparent glass, light transmission glass
Glass covers above the luminescent layer 2 of backlight, and light barrier 3 is rectangle, and light barrier 3 is slidably mounted on limitting casing 4 by sliding rail
On the frame of left and right, 3 slip plane of light barrier is parallel to luminescent layer 2 and glide direction is along the length side of the left and right frame of limitting casing 4
To light barrier 3 surrounds IPS screens rest area with limitting casing 4, and IPS screens rest area area can increase or subtract under 3 sliding mode of light barrier
It is small, there are two effects for light barrier 3, first, blocking the optical fiber beside IPS screens so that IPS screen surrounding brightness is relatively low, convenient for observation
Defect onto IPS screens, second is that light barrier 3 can resist IPS screens so that IPS screens were stablized is placed on transparent glass.
During use, according to the size of IPS screens to be tested, mobile light barrier 3 adjusts light barrier 3 and limitting casing
The size of the 4 IPS screens rest areas surrounded so that IPS screens to be tested can put IPS screens rest area into just, open backlight and be
IPS screens can be tested, the test of different size IPS screens can be met.
In the present embodiment, 1 upper plane angle with horizontal plane of babinet is 30 degree, then transparent glass angle with horizontal plane is
30 °, operator is sitting in the more convenient observation in backlight case side, in some other design methods, transparent glass and horizontal plane
Angle can be 10 °, 20 °, 40 °, 50 °.
In the present embodiment, a frame interior thickness of limitting casing 4 mutates, and affiliated lower frame thickness is smaller, institute
It states that framework upper thickness is larger, forms sliding distance of the limited step 41 for limiting light barrier 3, barrier slides installation at mutation
In affiliated lower frame, the movement of light barrier 3 as limited step 41 against when, be in the light to ensure light barrier 3 by upward sliding again
4 frame of limitting casing will not be skidded off.
It in the course of work, needs to lock after 3 location determination of light barrier, in the present embodiment, screw thread is offered on light barrier 3
Hole 31, bolt are resisted against across threaded hole 31 on limitting casing 4, and after 3 location determination of light barrier, screwing bolts make bolt firmly
It is resisted against on limitting casing 4, to which light barrier 3 be locked.
1 side of babinet is equipped with for controlling the button that backlight is turned on and off and the rotation for controlling back light source brightness
Button.
The limitting casing 4 of the present embodiment is not integrally formed with babinet 1, and 4 upper end of limitting casing is hinged on limit by hinge
On frame 4,4 lower end of limitting casing is connect by latching with babinet 1, and opening limitting casing 4 can will be in the replacement babinet 1 inside babinet 1
The weathered backlight in portion, operation are simple.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
