Specific embodiment
For making those skilled in the art more fully understand technical scheme, below in conjunction with the accompanying drawings and specific embodiment party
Formula is described in further detail to the present invention.
Embodiment 1
As Figure 4-Figure 6, the present embodiment provides a kind of open assembly 3 and liquid crystal display screen 17 bright spot with this open assembly 3
Prosthetic device.
A kind of open assembly 3 that the present embodiment provides, as shown in figure 4, open assembly 3 includes：Peripheral block piece（In Fig. 4
6 and 7）Block the opening 8 that assembly surrounds with periphery；Wherein, peripheral block piece include two pairs of opposed setting outer baffle, a pair
The plane interior energy being provided in open assembly 3 place makees the horizontal outer baffle 6 that longitudinally moves towards, another to being provided in opening
Longitudinal outer baffle 7 that the plane interior energy work that assembly 3 is located laterally moves towards.Two pairs of above-mentioned outer baffles are by drive mechanism, example
As Motor drive, move toward one another, thus forming opening 8, the shapes and sizes of opening 8 can pass through two pairs of outer baffles shape and
The direction of motion is adjusted.
Open assembly 3 also includes internal block piece, and described inside block piece is used for running through opening so that opening is divided into two
Part, forms two sub- openings 13, as shown in Figure 4.
By opening is gone up in the first direction or second direction that first direction is vertical on block, form two.Wherein, institute
The first direction stated can arbitrarily set that is to say, that being set according to the situation of concrete application.
Preferably, described opening 8 is rectangle, also just says that two is rectangle to outer baffle, thus forming rectangular opening
Mouth 8；Described inside block piece runs through opening 8 along the direction vertical with the long side a of described rectangular opening 8, forms two
Individual sub- opening 13, it is of course also possible to according to specific application scenario, the direction along the long side of parallel rectangular opening 8 is run through
Opening 8.Thus can be by opening 8 therefrom two sub- openings 13 of part one-tenth；The shape of preferred two sub- openings 13 is along opening 8
Centrage symmetrical.
Preferably, described inside block piece includes a pair of Internal baffle, and a pair of described Internal baffle is to have same shape
Right angled triangle Internal baffle 12.It should be appreciated that depending on the form of internal block piece can be according to the needs of application, as long as
Opening 8 can be all protection scope of the present invention from being divided into two sub- openings 13, for example, internal block piece can also be to fold to hide
Block piece, or there is the flexible block piece of Telescopic.
Preferably, the relative setting of the hypotenuse e of two right angled triangle Internal baffles 12, and angle identical oblique angle is towards phase
Instead, as shown in figure 4, the extended line of the hypotenuse e of two right angled triangle Internal baffles 12 overlaps, one of right angled triangle Internal baffle 12
Angle of bevel is A, a right-angle side b of right angled triangle Internal baffle 12 right angle vertical, described with the long side a of oblong openings
Triangle Internal baffle 12 can make move toward one another along the extended line of hypotenuse e place straight line.
By adjust right angled triangle Internal baffle 12 move towards relative distance, the shape of two sub- openings 13 of formation
Centrage along opening 8（In Fig. 4 shown in dotted line）Symmetrically, thus, the irradiation area 9 of laser beam also can be along the center of sub-pixel 5
Line（In Fig. 6 shown in dotted line）Symmetrically, convenient black matrix pending area 10 operation simultaneously to sub-pixel 5 both sides simultaneously.In addition,
It should be noted that Internal baffle 12 is driven by drive mechanism, in figure is shown without.It is understood that can also be by figure
90 ° of two right angled triangle Internal baffle 12 integral-rotations, run through rectangular opening 8 from another one direction.
As shown in figure 5, the present embodiment provides liquid crystal display screen 17 bright spot prosthetic device, including laser instrument 14, wherein, laser instrument 14
There is above-mentioned open assembly 3, laser instrument 14 is movably disposed at as on the crossbeam 15 of support member, laser instrument 14 is by driving
The first direction motion that motivation structure drives edge crossbeam 15 is located（The X-direction of in figure）, this first direction can be flat with sub-pixel 5
Capable or vertical direction, wherein, drive mechanism can be Motor drive（It is shown without in Fig. 5）.
Crossbeam 15 is by linear electric motors 16 drives edge and above-mentioned first direction（X-direction in Fig. 5）Vertical second direction
（Y-direction in Fig. 5）, crossbeam 15 motion drive laser instrument 14 moves in a second direction, realizes laser instrument 14 and liquid crystal display screen 17
Relative displacement, thus control laser instrument 14 to move to the position that the sub-pixel 5 being keeped in repair is located.
As shown in fig. 6, the rectangle outer baffle of the open assembly 3 being arranged on by adjustment on laser instrument 14（6 and 7）And right angle
The relative position of triangle Internal baffle 12 so that the laser beam that laser instrument 14 sends is divided into two bundles by sub- opening 13, and two
The irradiation of bundle laser beam is symmetric on sub-pixel 5, is radiated at the black matrix pending area of sub-pixel 5 both sides respectively
10, and suitable with black matrix pending area 10 width.
It is understood that the shapes and sizes of sub- opening 13 can adjust as needed.For example according to different shaped
The size of work song pixel 5 is adjusted, you can realize the compatibility of different model sub-pixel 5 size, can correspond to the sub- picture of sizes
The maintenance of element 5.
Specifically, first adjust rectangle outer baffle（6 and 7）Relative position so that the width of the width of opening 8 and sub-pixel 5
Degree is quite.Then the relative position of adjustment right angled triangle Internal baffle 12 make region that right angled triangle Internal baffle 12 blocks and
The width of the viewing area 11 of sub-pixel 5 quite, treat with by the black matrix of maintenance sub-pixel 5 both sides by the width of two sub- openings 13
Processing region 10 width quite, then pass through two sub- opening 13 laser beams on sub-pixel 5 width of projected area 14 with tieed up
Black matrix pending area 10 width repairing sub-pixel 5 both sides is suitable.Form two to be suitable for by maintenance sub-pixel 5 both sides
Black matrix pending area 10 operation simultaneously laser beam.
Two laser beams are driven to move reciprocatingly in black matrix pending area 10 during the mass motion of laser instrument 14, can be same
When operation is carried out simultaneously to the black matrix pending area 10 of both sides.The energy of laser is iteratively operating on black matrix pending area
Make black matrix become black particle on 10, fall into the effect in viewing area 11, bright spot being keeped in repair into dim spot.
The liquid crystal display screen bright spot prosthetic device of the present invention is due to being that two laser beams simultaneously act on sub-pixel 5 viewing area 11
The black matrix pending area 10 of both sides, is halved making black matrix granulate the time in this time-consuming operation the longest, from
And the time that liquid crystal display screen bright spot prosthetic device keeps in repair bright spot decreases 40% about, liquid crystal display screen bright spot prosthetic device keeps in repair bright spot
Production capacity improves 67% about.
It is understood that the embodiment of above principle being intended to be merely illustrative of the present and the exemplary enforcement adopting
Mode, but the invention is not limited in this.For those skilled in the art, in the essence without departing from the present invention
In the case of god and essence, various modifications and improvement can be made, these modifications and improvement are also considered as protection scope of the present invention.
