Glasses

Technical Field

The invention relates to the technical field of display, in particular to a pair of glasses.

Background

A Color Filter (CF), also called a Color film, is an important component of a liquid crystal display panel, and is an essential part for forming a Color display screen, in which three Color resists, i.e., red (R), green (G), and blue (B), provide a hue. BM (Black Matrix, light-shielding pattern), ITO (Indium Tin Oxide), PS (Photo Spacer), etc. are also required to be formed in the manufacturing process of the color film substrate, and in the manufacturing process of these parts, a certain area on the color film substrate and a peripheral normal film layer generate color difference due to slight differences in equipment and processes, such as uneven thickness of a coated photoresist, uneven platform temperature or pressure during exposure, contamination or scratch of an exposure mask plate, etc., which is known as Mura (Mura) in the industry. The Mura of the color film substrate mainly includes horizontal line-shaped Mura, vertical line-shaped Mura, dot-shaped Mura and the like, and the Mura directly affects the display effect of a final product, for example, the display on a liquid crystal display is poor in horizontal line, vertical line, black dot, white dot and the like, so that the display effect is affected.

In appearance, when light irradiates the surface of the color film substrate without Mura, diffraction and scattering occur, and the visual effect of a regular image is seen by human eyes. When Mura occurs on the surface of the color film substrate, the condition of the surface of the color film substrate is changed, and as a result, images seen by human eyes are greatly different, and the visual effect is influenced. The macro inspection is to inspect the Mura on the surface of the color film substrate by using the difference of the visual effect.

At present, there are two main types of macroscopic inspection: one is inspection using a CCD (Charge Coupled Device) detector, and the other is direct visual inspection by the human eye.

However, the CCD detector is expensive, which results in high detection cost.

Direct visual inspection by the human eye is also a common method for quality inspection, which is a complete macroscopic inspection by the naked eye. The detection rate and accuracy of Mura are greatly related to the detection capability of an inspector due to the fact that direct detection is mainly carried out through human eyes, and strong light used in the detection causes eye fatigue of the inspector, so that the eye fatigue also causes damage to the eyes of the inspector in a long term, and the eye fatigue also has a great influence on the detection result.

The embodiment of the invention provides glasses, which comprise a first scroll and a second scroll, wherein the first scroll and the second scroll are respectively connected with two ends of an optical filter, so that the optical filter can move under the traction of the first scroll and/or the second scroll. In addition, since the filter is composed of a plurality of segments of single-color sub-filters, and the colors of the plurality of segments of sub-filters include at least two of red, green, blue, yellow, and transparent, the colors of the single-color sub-filters in the frame may be changed during movement of the filter.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

An embodiment of the present invention provides glasses, as shown in fig. 1(a) and 1(b), including: a frame 10; the optical filter 20, the optical filter 20 is formed by a plurality of segments of monochromatic sub-optical filters 201, and the colors of the plurality of segments of sub-optical filters 201 comprise at least two of red, green, blue, yellow and transparent; the first reel 30 and the second reel 40 are arranged at two opposite sides of the lens frame 10, the relative positions of the first reel 30 and the second reel 40 are fixed, and the first reel 30 and the second reel 40 are respectively connected with two ends of the optical filter 20 and used for winding the optical filter 20; wherein the length of the monochromatic sub-filters 201 in the direction from the first reel 30 to the second reel 40 is equal or approximately equal to the distance from the first reel 30 to the second reel 40.

First, the structure of the frame 10 is not limited, and one frame 10 may be configured by one frame as shown in fig. 1(a), or the frame 10 may be configured by a plurality of frame sub-portions 101 as shown in fig. 1(b), and both the first reel 30 and the second reel 40 are connected to the frame sub-portions 101 and are rotatable with respect to the frame sub-portions 101. Here, when the lens frame 10 is the lens frame 10 shown in fig. 1(a), convex edges may be provided on the upper and lower sides of the lens frame 10, respectively, so as to guide the movement of the optical filter 20 and prevent the optical filter 20 from being misaligned.

Second, the number of the monochromatic sub-filters 201 included in the filter 20 is not limited, and may be set as needed. For example, the filter 20 may include two segments of sub-filters 201, or may include more than two segments of any multi-segment sub-filters 201. Wherein, the colors of the multi-segment sub-filters 201 are not completely the same.

Third, the relative positions of the first roller 30 and the second roller 40 are fixed, i.e. the distance between the first roller 30 and the second roller 40 is kept constant.

How to fix the relative positions of the first reel 30 and the second reel 40 is not limited, and for example, when the frame 10 is a frame 10 as shown in fig. 1(a), the relative positions of the first reel 30 and the second reel 40 can be fixed by the frame 10; when the frame 10 is a frame 10 as shown in fig. 1(b), a bridge may be provided between the opposing frame sub-portions 101, and the relative positions of the first reel 30 and the second reel 40 may be fixed by the bridge, or the eyeglasses may further include lenses, and the relative positions of the first reel 30 and the second reel 40 may be fixed by the lenses.

Fourth, the connection mode between the first and

second reels

30 and 40 and the both ends of the filter 20 is not limited. For example, the end of the filter 20 may be wound around the first reel 30 to connect the filter 20 to the first reel 30, and/or the end of the filter 20 may be wound around the second reel 40 to connect the filter 20 to the second reel 40; a connection part may be provided on the first reel 30, and a connection part may also be provided at an end of the optical filter 20 connected to the first reel 30, and the two connection parts may be connected to each other, so that the first reel 30 is connected to the end of the optical filter 20; and/or, the second reel 40 is provided with a connecting part, the end of the filter 20 connected with the second reel 40 is also provided with a connecting part, and the two connecting parts can be connected with each other to connect the second reel 40 with the filter 20.

Fifthly, along the direction from the first reel 30 to the second reel 40, the length of the monochromatic sub-filter 201 may be equal to or approximately equal to the distance from the first reel 30 to the second reel 40, where the approximate range should satisfy that after the sub-polarizer 201 is moved into the frame 10, the normal viewing of the user is not affected after the user wears the glasses.

Sixthly, the glasses in the drawings in the embodiments of the present invention only illustrate one segment of the monochromatic sub-filters 201, and the other segments of the monochromatic sub-filters 201 are wound on the first reel 30 and/or the second reel 40.

The embodiment of the invention provides a pair of glasses, wherein the glasses comprise a first reel 30 and a second reel 40, the first reel 30 and the second reel 40 are respectively connected with two ends of an optical filter 20, and therefore the optical filter 20 can move under the traction of the first reel 30 and/or the second reel 40. In addition, since the filter 20 is composed of a plurality of segments of the monochromatic sub-filters 201, and the colors of the plurality of segments of the sub-filters 201 include at least two of red, green, blue, yellow, and transparent, the color of the monochromatic sub-filters 201 in the lens frame 10 may be changed during the movement of the filter 20. Based on the above, when the glasses are used for inspecting a color film substrate, the sub-filters 201 with required colors can be moved into the frame 10 as required, so that when macroscopic chromatic aberration of the color film substrate is inspected, veiling glare during inspection can be filtered, and only optical information beneficial to Mura inspection is received, so that human eyes can distinguish the veiling glare, interference is eliminated, and Mura inspection is facilitated. Compared with a CCD detector, the cost can be reduced, the detection accuracy can be improved compared with direct visual detection of human eyes, and the damage of strong light to human eyes can be reduced because the optical filter 20 can filter partial light.

A color filter substrate in the prior art includes a Black Matrix (BM), a blue color filter (B), a green color set (G), a red color set (R), a transparent planarization layer (OC), and a spacer (PS). When a film layer on a color film substrate is manufactured, according to the sequence of the process flow, each process needs to perform sampling inspection on the appearance. However, when examining Mura of the current process, it is susceptible to the completed process. Based on this, the preferred embodiment of the present invention provides that the filter 20 includes a red sub-filter, a green sub-filter, a blue sub-filter, a yellow sub-filter and a transparent sub-filter.

In the embodiment of the present invention, since the optical filter 20 includes the red sub-optical filter, the green sub-optical filter, the blue sub-optical filter, the yellow sub-optical filter, and the transparent sub-optical filter, the surface of the color film substrate can be inspected by using the red optical filter after the red photoresist on the color film substrate is completed, and the red optical filter can filter the interference of light of other colors except red to the human eye, so that the inspection of the poor appearance of the color film caused by the red photoresist is facilitated. Similarly, the blue filter and the green filter can be used to respectively inspect the color film appearance defects caused by the blue light resistance and the green light resistance.

Here, since the transparent planarization layer is made of a material, when inspecting the transparent planarization layer, the transparent planarization layer is generally inspected by yellow light having a specific wavelength. The transparent flat layer can be inspected with a yellow sub-filter in order to allow yellow light of a specific wavelength to pass through the filter and light of other colors to not pass through the filter. When inspection with colored filters is not required, the transparent sub-filters can be moved into the frame 10 to facilitate additional inspection.

In addition, since human eyes are most sensitive to green light, the color film substrate can be inspected by using a green sub-filter in each process.

Preferably, as shown in fig. 2, the spectacles further comprise a transparent lens 50 embedded in the frame 10, the transparent lens 50 being used to provide support for the optical filter 20 during its movement.

The thickness and material of the transparent lens 50 are not limited.

Preferably, the transparent lens 50 is made of light wear-resistant resin material, on one hand, the weight of the glasses can be reduced, so that the glasses are light and convenient to wear; on the other hand, the filter 20 can be prevented from rubbing the transparent lens 50 during movement.

Preferably, as shown in fig. 3, the glasses further include a first driving device 60 and a second driving device 70 disposed on the frame 10, wherein the first driving device 60 is used for driving the first reel 30 to rotate, and the second driving device 70 is used for driving the second reel 40 to rotate.

The specific structure of the first driving device 60 and the second driving device 70 is not limited, and the first driving device 60 and the second driving device 70 may be, for example, a motor or a motor.

Here, the first driving device 60 and the second driving device 70 may simultaneously drive the first reel 30 and the second reel 40 to rotate, or when the first driving device 60 drives the first reel 30 to rotate, the second driving device 70 does not work, and since two ends of the optical filter 20 are respectively connected to the first reel 30 and the second reel 40, in the process that the first driving device 60 drives the first reel 30 to rotate, the second reel 40 also rotates correspondingly under the driving of the optical filter 20; of course, the first driving device 60 may not be operated, and the second driving device 70 may drive the second reel 40 to rotate, and similarly, the first reel 30 may be driven by the optical filter 20 to rotate.

The number of turns of the first rotating shaft 30 is related to the time of driving by the first driving device 60, and the longer the time of driving by the first driving device 60 is, the more turns of the first rotating shaft 30 are; similarly, the number of rotations of the second shaft 40 is related to the driving time of the second driving device 70.

The direction in which the first driving device 60 drives the first rotating shaft 30 to rotate and the direction in which the second driving device 70 drives the second rotating shaft 40 to rotate may be the same or different, and this is not limited.

In the embodiment of the present invention, the first driving device 60 and the second driving device 70 respectively drive the first reel 30 and the second reel 40 to rotate, so that the optical filter 20 can be moved to switch the sub-optical filters 201 in the frame 10. The first and

second driving devices

60 and 70 may rapidly rotate the first and

second spools

30 and 40 as compared to manually rotating the first and/or

second spools

30 and 40 using a human.

Further preferably, as shown in fig. 4, the glasses further comprise a controller 80, and the controller 80 is connected to the first driving device 60 and the second driving device 70 for controlling the first driving device 60 and the second driving device 70 to start and stop, respectively.

Here, when the first driving device 60 and/or the second driving device 70 is turned on, the first reel 30 and the second reel 40 are rotated; the first and second driving means 60 and 70 are turned off, and the first and

second reels

30 and 40 stop rotating.

Based on this, the controller 80 of the embodiment of the present invention controls the time when the first driving device 60 and/or the second driving device 70 are turned on, so that the number of turns of the first reel 30 and the second reel 40 can be precisely controlled, thereby ensuring that the required sub-filter 201 can be moved into the lens frame 10.

Further, as shown in fig. 5, the glasses further include a selection button 90, and the selection button 90 is connected to the controller 80 and is used for determining the sub-filters 201 to be moved into the frame 10; the controller 80 is configured to determine an operation time of the first driving device 60 and/or the second driving device 70 according to a pre-stored time from when the optical filter 20 is moved from the initial sub-optical filter 201 to when each of the other sub-optical filters 201 is moved into the lens frame 10, a current position of the optical filter 201, and a sub-optical filter 201 of the optical filter 20 that needs to be moved into the lens frame 10, so as to control the first driving device 60 or the second driving device 70 to start and stop according to the operation time.

The number of the selection keys 90 is not limited, and may be set as needed. Each of the selection buttons 90 corresponds to the sub-filter 201 moved into the frame 10. For example, the selection keys 90 include a number 1 key, the number 1 key corresponds to the red sub-filter, and when the number 1 key is pressed, the red sub-filter moves into the lens frame 10. Of course, the selection key 90 may also include a key 2, where the key 2 corresponds to the blue sub-filter, and so on, and will not be described herein again.

Here, a detailed description is provided below of a specific embodiment of how the controller 80 controls the desired sub-filters 201 to move into the frame 10.

Illustratively, the filters 20 include a red sub-filter, a green sub-filter, a blue sub-filter, a yellow sub-filter, and a transparent sub-filter, which are respectively numbered as: 00. 01, 02, 03, 04. If the initial sub-filter 201 in the frame 10 is a red filter, the time for moving each of the other sub-filters 201 into the frame 10 is shown in table 1.

In the first mode, the first driving device 60 and the second driving device 70 drive the first reel 30 and the second reel 40 to rotate in the same direction. If the first driving device 60 and the second driving device 70 drive the first reel 30 and/or the second reel 40 to rotate clockwise, the sequence of moving the sub-filters 201 into the lens frame 10 is as follows: 00-01-02-03-04; if the first driving device 60 and the second driving device 70 drive the first reel 30 and/or the second reel 40 to rotate counterclockwise, the sequence of moving the sub-filters 201 into the lens frame 10 is as follows: 04-03-02-01-01.

If the current sub-filter 201 in the frame 10 is the initial sub-filter 00, and if it is necessary to move the sub-filter 03 into the frame 10, the controller 80 controls the first driving device 60 and/or the second driving device 70 to operate for time T3, since the time T3 is the time when the sub-filter 03 is moved from the initial sub-filter 00 into the sub-filter 03, so that the sub-filter 03 can be moved into the frame 10.

If the current sub-filter in the frame 10 is 03, if it is required to move the sub-filter 01 into the frame 10, the controller 80 controls the first driving device 60 to drive the first reel 30 to rotate counterclockwise and/or the second driving device 70 to drive the second reel 40 to rotate counterclockwise, and controls the first driving device 60 and/or the second driving device 70 to have a running time T3-T2, so as to move the sub-filter 01 into the frame 10.

The second method comprises the following steps: the first driving device 60 drives the first reel 30 to rotate in a different direction than the second driving device 70 drives the second reel 40 to rotate. If the first driving device 60 drives the first reel 30 to rotate clockwise, the sequence of moving the sub-filter 201 into the lens frame 10 is as follows: 00-01-02-03-04, the second driving device 70 drives the second reel 40 to rotate counterclockwise, and the sequence of moving the sub-filters 201 into the lens frame 10 is as follows: 04-03-02-01-01.

If the current sub-filter 201 in the frame 10 is the initial sub-filter 00, and the sub-filter 03 needs to be moved into the frame 10, the controller 80 can control the first driving device 60 to operate for time T3, since the time from the initial sub-filter 00 to the sub-filter 03 is T3, so that the sub-filter 03 can be moved into the frame 10.

If the current sub-filter in the frame 10 is 03, and it is necessary to move the sub-filter 01 into the frame 10, the controller 80 may control the second driving device 70 to operate for a time period T3-T2, so as to move the sub-filter 03 into the frame 10.

In the embodiment of the present invention, since the glasses include the selection button 90, when the selection button 90 is pressed, the sub-filter 201 corresponding to the selection button 90 can be quickly moved into the frame 10, so that the glasses are more intelligent.

Further, as shown in fig. 5, the glasses further include a reset button 100, and the reset button 100 is connected to the controller 80 for resetting the optical filter 20 to the initial position.

Here, since the reset button 100 is connected to the controller 80, the controller 80 can control the driving time of the first driving device 60 and/or the second driving device 70 according to the time when the filter 20 moves from the initial sub-filter 201 to the sub-filter 201 currently in the frame 10, thereby moving the initial sub-filter 201 into the frame 10 even if the filter 20 is reset to the initial position. How the controller 80 controls the required initial sub-filters 201 to move into the lens frame 10 is the same as the above method, and is not described herein again.

In the embodiment of the present invention, since the glasses include the reset button 100, the optical filter 20 can be reset to the initial position by pressing the reset button 100, which is convenient for readjusting the position of each sub-optical filter 201. When one of the first driving device 60 and the second driving device 70 is damaged, the other driving device and the reset button 100 may be used to move the desired sub-filter 201 into the lens frame 10.

Preferably, as shown in fig. 6, the eyeglasses further comprise a frame 110, the frame 10 comprises a first engaging portion 102, the frame 110 comprises a second engaging portion 103, and the first engaging portion 102 and the second engaging portion 103 can be engaged with each other.

The structure of the first engaging portion 102 and the second engaging portion 103 is not limited, and the first engaging portion 102 and the second engaging portion 103 may be engaged with each other. For example, the first engaging portion 102 is a groove, and the second engaging portion 103 is a protrusion; alternatively, the first engaging portion 102 is a protrusion, and the second engaging portion 103 is a groove.

In the embodiment of the present invention, since the first engaging portion 102 and the second engaging portion 103 can be engaged with each other, the frame 10 and the frame 110 can be detached as needed.

Preferably, the first engaging portion 102 and the second engaging portion 103 are magnetically attracted to each other.

The materials of the first engaging portion 102 and the second engaging portion 103 are not limited, and the first engaging portion 102 and the second engaging portion 103 may be magnetically attracted to each other. For example, the first engaging portion 102 includes a magnet, and the second engaging portion 103 includes a ferromagnetic substance such as iron, cobalt, nickel, or ferrite; alternatively, the first engaging portion 102 includes a ferromagnetic substance such as iron, cobalt, nickel, or ferrite, and the second engaging portion 103 includes a magnet.

It should be noted that, the process of the color film substrate is generally performed in a dust-free environment, so that when the color film substrate is inspected, an inspector needs to wear protective clothing such as dust-free clothes and headgear, and it is very inconvenient to insert the spectacle frame 110 into the headgear when wearing the spectacles. However, since the frame 10 of the glasses according to the embodiment of the present invention includes the first engaging portion 102 and the frame 110 includes the second engaging portion 103, the frame 10 and the frame 110 can be detached from each other, so that an inspector can wear the frame 110 of the glasses before wearing a clean wear headgear and then wear the clean wear headgear, and wear the frame 10 when the inspection of the optical filter 20 is required, and since the first engaging portion 102 and the second engaging portion 103 can attract each other magnetically, the frame 10 worn outside the headgear can attract each other magnetically with the frame 110 worn inside the headgear, thereby preventing the frame 10 from falling off. On this basis, for the examiner with self myopia, the examiner wears the approximate glasses, and when the examiner wears the eyeglasses according to the embodiment of the present invention, since the frame 110 of the eyeglasses according to the embodiment of the present invention includes the second engaging portion 103, the frame of the myopia eyeglasses can be further engaged with the second engaging portion 103, and at this time, the second engaging portion 103 is a groove, the frame 10 worn by the myopia examiner needs to be provided with a clip as compared with the prior art, and thus the frame 10 according to the embodiment of the present invention can be applied to both the myopia examiner and the non-myopia examiner.

In the embodiment of the present invention, since the first engaging portion 102 and the second engaging portion 103 can be attracted to each other by magnetism, on one hand, the first engaging portion 102 and the second engaging portion 103 can be firmly connected; on the other hand, the glasses can be applied to the case that when an inspector wears a dust-free clothes head cover, the glasses frame 110 can be worn in the head cover, the glasses frame 10 is worn outside the head cover, the glasses frame 10 and the glasses frame 110 cannot be separated, and the inspector can conveniently wear and remove the glasses even when wearing the dust-free head cover.

Preferably, as shown in fig. 7, the frame 10 includes oppositely disposed reel boxes 120, and the first reel 30 and the second reel 40 are respectively disposed in the reel boxes 120; the reel case 120 has a slit through which the filter 20 is movable.

The shape of the reel case 120 is not limited, and may be a cylindrical shape, a rectangular parallelepiped shape, or other shapes.

Here, the reel cassette 120 may be openable or not openable, and is not limited thereto.

In the embodiment of the present invention, since the frame 10 of the glasses includes the reel box 120, the first reel 30 and the second reel 40 are disposed in the reel box 120, on one hand, the contamination of the optical filter 20 can be reduced; on the other hand, the first and

second reels

30 and 40 can be prevented from being affected by the external environment when they rotate.

Further preferably, as shown in fig. 8, the reel case 120 includes a case body 1201 having an opening and a case cover 1202 covering the opening of the case body 1201.

Since the reel case 120 includes the case body 1201 having the opening and the case cover 1202 covering the opening of the case body 1201, the reel case 120 can be opened or closed, and thus when the optical filter 20 is worn out for a while, the case cover 1202 can be opened to facilitate replacement of the optical filter 20 in the reel case 120.

Preferably, as shown in fig. 9, the glasses further include a connecting band 130 connected to the two frames 110, and the connecting band 130 has elasticity.

Here, the material of the connection band 130 is not limited as long as the connection band 130 has elasticity.

Since the glasses include the connection band 130, the connection band 130 can be fitted over the head when the glasses are worn, so that the glasses can be prevented from slipping off.

Preferably, the first reel 30 and/or the second reel 40 are provided with a third engaging structure, the end of the optical filter 20 is provided with a fourth engaging structure, and the third engaging structure and the fourth engaging structure can be engaged.

The types of the third engaging structure and the fourth engaging structure are not limited as long as the third engaging structure and the fourth engaging structure can be engaged and connected. For example, the third engaging structure may be a hook and the fourth engaging structure may be a hole.

Here, the third engaging structure may be provided only on the first reel 30, the fourth engaging structure may be provided at one end of the optical filter 20 connected to the first reel 30, the third engaging structure may be provided only on the second reel 40, the fourth engaging structure may be provided at one end of the optical filter 20 connected to the second reel 40, the third engaging structure may be provided on both the first reel 30 and the second reel 40, and the fourth engaging structure may be provided at both ends of the optical filter 20.

In the embodiment of the present invention, if the first reel 30 is provided with the third engaging structure, since the third engaging structure can be engaged with the fourth engaging structure on the optical filter 20, the optical filter 20 is connected to the first reel 30 by winding, so that the optical filter 20 can be prevented from falling off from the first reel 30 due to excessive rotation of the first reel 30; similarly, if the second reel 40 is provided with a third engaging structure, the third engaging structure is connected to the fourth engaging structure, so that the second reel 40 can be prevented from rotating too much, and the optical filter 20 can be prevented from falling off from the second reel 40.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
