The embodiment of the application provides a mask, a display panel and a display device, and solves the problem that the area of the top of a spacer manufactured by exposure of the existing mask is too small easily, so that the liquid crystal display panel is pierced in the using process.

Example one

Referring to fig. 1, a mask according to an embodiment of the present invention includes a first mask pattern area 10, where the first mask pattern area 10 includes a plurality of bands 11 arranged along a first direction, and light transmittance of the bands 11 along the first direction decreases; the first direction is a direction in which the edge of the first mask pattern area 10 points to the center.

Through the mask that this application embodiment provided, set up the luminousness of a plurality of frenulum 11 that arrange along the first direction that first mask pattern area 10 includes and descend progressively decrease along the first direction, the first direction is the direction of the edge directional center of first mask pattern area 10, when exposing, because diffraction and the interference effect of light, the height of the spacer center that forms is slightly less than the height of edge, under the effect of tension, the spacer edge collapses downwards, the edge and the center height of the top surface of final spacer keep on a plane, the top area grow of the spacer of round platform form promptly, more be close to the bottom area, thereby can avoid spacer top area undersize and lead to the fact the impaling in the use of liquid crystal display panel.

It should be noted that the MASK in the embodiment of the present application is a photomask, which is also called MASK, and also called MASK in chinese, and also called photomask and chrome plate. Photomasks are structures that produce various functional patterns and are precisely positioned on a film, plastic or glass substrate for selective exposure of a photoresist coating. The mask is widely used, and the mask is required to be used in the field related to the photolithography process, such as IC (Integrated Circuit), FPD (Flat Panel display, Di spray), PCB (Printed Circuit Boards), MEMS (Micro Electro Mechanical Systems), and the like. The mask in the embodiment of the application is mainly used for manufacturing the shock insulator.

It can be understood that, when the spacer is manufactured by the mask, due to the limitation of the existing process technology, the shape of the manufactured spacer is often inconsistent with the shape of the designed spacer, for example, the spacer is designed to be circular, theoretically, the manufactured spacer should be cylindrical, but actually, during exposure, the top surface of the spacer first contacts with a light source to start curing, which results in blocking part of the light source, so that the developed finished product is a circular truncated cone with a thick top and a thin bottom, the developed spacer is not completely solid, and has a certain fluidity, at this time, baking is performed, due to the action of high temperature and gravity, the top of the spacer flows downward, and then is cured completely, and finally, a circular truncated cone with a thick top and a thin bottom is formed, and when the circular truncated cone-shaped spacer is too sharp, the display panel may be punctured during use.

The light transmittance of the mask pattern used for manufacturing the spacer through exposure is set to be decreased from the edge to the center, the light transmittance is related to the height of the spacer, the light transmittance is higher, the height of the spacer is higher, therefore, the height of the center of the semi-finished spacer, which is correspondingly formed when the first mask pattern area 10 of the mask is exposed, of the first mask pattern area 10 of the mask is lower than the height of the edge, the semi-finished spacer is developed and baked, and the material at the edge of the semi-finished spacer formed through exposure flows downwards, so that the top surface area of the formed finished spacer is increased compared with the top surface area of the finished spacer manufactured through holes with uniform light transmittance in the prior art, the spacer is located in the display panel and cannot puncture the display panel, and the use performance of the display panel is guaranteed.

It should be noted that, in the embodiment of the present application, the transmittance of the plurality of bands 11 decreases progressively along the first direction, specifically, the transmittance may decrease in a step manner or in a linear manner.

Referring to fig. 1, in a first embodiment of the present application, a first mask pattern region 10 includes a plurality of first light-transmitting slits 20 and a plurality of first light-shielding bars 30 alternately arranged along a first direction; along the first direction, the widths of the first light-transmitting slits 20 are decreased progressively, and the widths of the first light-shielding strips 30 are decreased progressively or are equal; wherein adjacent first light-transmitting slits 20 and first light-blocking strips 30 form the band 11.

It should be noted that the first mask pattern area 10 includes a plurality of first light-transmitting slits 20 and a plurality of first light-shielding strips 30 alternately arranged along the first direction, and the width of the first light-transmitting slits 20 decreases progressively, and the width of the first light-shielding strips 30 decreases progressively or is equal, so that the area of the first light-transmitting slits 20 in the plurality of bands 11 arranged along the first direction is made smaller and smaller, and the ratio of the area of the first light-transmitting slits 20 to the total area of the bands 11 is made smaller and smaller, and the light transmittance of the plurality of bands 11 arranged along the first direction is made smaller and smaller by the diffraction and interference action of light, thereby achieving the effect that the light transmittance of the first mask pattern area 10 decreases progressively along the first direction.

It can be understood that the first light transmitting slits 20 and the first light-shielding bars 30 of the first mask pattern region 10 are specifically disposed in the following manner: the glass substrate of the mask plate is coated with a layer of shading layer, a part of the coating layer is scraped to form a first light-transmitting slit 20, the first light-transmitting slit 20 can transmit light, the shading layer between two adjacent first light-transmitting slits 20 is a first shading strip 30, the first shading strip 30 is used for shading light, and when the first light-transmitting slits 20 and the first shading strip 30 are alternately arranged, the light transmittance of the first mask pattern area 10 is lower than 100% due to diffraction and interference of light. The light transmittance of the first mask pattern region 10 can be determined according to the number and width of the first light-transmitting slits 20 and the number and width of the first light-shielding bars 30.

Referring to fig. 1, in the first embodiment of the present application, a plurality of first light transmission slits 20 and a plurality of first light-shielding bars 30 surround a center point of a first mask pattern region 10. The first light-transmitting slits 20 and the first light-shielding strips 30 are all in the shape of a square ring.

It should be noted that, in the first embodiment of the present application, the plurality of first light-transmitting slits 20 and the plurality of first light-shielding strips 30 may be all configured to be square-ring shaped, at this time, the first mask pattern area 10 is square, the plurality of first light-transmitting slits 20 and the plurality of first light-shielding strips 30 all surround the central point of the first mask pattern area 10, so that the first mask pattern area 10 may be integrally represented as a square-shape, the belt area 11 included in the first mask pattern area 10 is also represented as a square-ring shaped, the light transmittance of the first mask pattern area 10 decreases progressively from the peripheral edge to the center of the first mask pattern area 10, and the light transmittance at each position on the first mask pattern area 10 may decrease progressively more uniformly, so that the shape of the manufactured spacer meets the design requirements more, and no deformity occurs.

Example two

Referring to fig. 2, in the first embodiment, when the plurality of first light-transmitting slits 20 and the plurality of first light-shielding strips 30 surround the center point of the first mask pattern region 10, the plurality of first light-transmitting slits 20 and the plurality of first light-shielding strips 30 are all circular.

It should be noted that, in the second embodiment of the present application, the plurality of first light-transmitting slits 20 and the plurality of first light-shielding strips 30 may be all configured to be circular, at this time, the first mask pattern area 10 is circular, the plurality of first light-transmitting slits 20 and the plurality of first light-shielding strips 30 all surround the central point of the first mask pattern area 10, so that the first mask pattern area 10 may be integrally concentric circular, the belt area 11 included in the first mask pattern area 10 is also circular, the light transmittance of the first mask pattern area 10 decreases progressively from the peripheral edge of the first mask pattern area 10 to the center, the light transmittance at each position on the first mask pattern area 10 decreases progressively more uniformly, and the concentric circular first mask area 10 is also beneficial to manufacturing a spacer with a circular bottom surface, so that the shape of the manufactured spacer meets the design requirement more, no deformity occurs.

In the first to second embodiments, the shape of the first mask pattern region 10 is the same as the shape of the first light transmission slits 20 and the first light-shielding bars 30, so the shape of the first mask pattern region 10 may be square or circular, but besides, the shape of the first mask pattern region 10 may also be regular pentagon or polygon shape with more than five sides. Specifically, when first mask pattern region 10 is designed to be regular pentagon, a plurality of first printing opacity slits 20 and a plurality of first light shading strip 30 are just for regular pentagon's ring, when first mask pattern region 10 is designed to be regular hexagon, a plurality of first printing opacity slits 20 and a plurality of first light shading strip 30 are just for regular hexagon's ring, specifically can go to select according to actual need, the shape of first mask pattern region 10 of this application embodiment is multiple, can satisfy the demand under more different manufacturing scenes, and the range of application is wider.

EXAMPLE III

Referring to fig. 3, in the third embodiment of the present application, the plurality of first light-transmitting slits 20 and the plurality of first light-shielding bars 30 are all strip-shaped and are parallel to each other.

It should be noted that, in the third embodiment of the present application, the plurality of first light-transmitting slits 20 and the plurality of first light-shielding bars 30 may be all configured as a bar, and are parallel to each other, the plurality of first light-transmitting slits 20 and the plurality of first light-shielding bars 30 are vertically arranged in the first mask pattern region 10 in sequence along the first direction, and the first mask pattern region 10 includes the band 11 also in the form of a bar, in which case the shape of the first mask pattern region 10 may be set to a square, circular, regular pentagon and above polygon shape, when the first mask pattern region 10 has a square shape, the plurality of first light transmitting slits 20 and the plurality of first light-shielding bars 30 may be arranged in a horizontal direction in the first mask pattern region 10, or arranged along a vertical direction, or arranged along a direction inclined at an angle of 45 degrees, or arranged along any other inclined angle direction, which is not limited in the third embodiment of the present application.

It can be understood that, when the plurality of first light-transmitting slits 20 and the plurality of first light-shielding strips 30 are all in a strip shape and are arranged in parallel with each other, the light transmittances of the plurality of bands 11 decrease progressively along the first direction, that is, the light transmittance is lowest at the central point of the first mask pattern region 10 and then increases progressively toward both sides, which also increases the top area of the produced spacer.

Example four

Referring to fig. 4, in the fourth embodiment of the present application, the transmittance of the first mask pattern region 10 is gradually decreased along the first direction; the area of arbitrary width taken along the first direction in the first mask pattern area 10 forms a band 11.

It should be noted that, in the fourth embodiment of the present application, the transmittance of the first mask pattern region 10 is gradually decreased along the first direction, which means that the transmittance of the first mask pattern region 10 is linearly decreased along the first direction. Specifically, a light-transmitting film may be used as the first mask pattern area 10, and the light transmittance of the light-transmitting film gradually decreases along the first direction, where the band 11 is an area of any width cut along the first direction in the first mask pattern area 10, for example, a ring-shaped area may be taken as the band 11, or a strip-shaped area may be taken as the band 11, for example, in fig. 4, the light transmittance at a position close to the center of the first mask pattern area 10 is 20%, and the light transmittance at a position relatively far from the center of the first mask pattern area 10 is 23%. The design mode of taking the light-transmitting film as the first mask pattern area 10 is simple, the effect that the light transmittance of the first mask pattern area 10 is gradually reduced along the first direction can be realized by directly arranging one light-transmitting film, the light-transmitting film is taken off, the light transmittance of the first mask pattern area 10 is changed into 100 percent, and the light-transmitting film can be continuously used as a common mask plate to manufacture the spacer.

Referring to fig. 1 to 4, in the reticles according to the first to fourth embodiments of the present application, the reticles further include a second mask pattern region 40, and the transmittance of the second mask pattern region 40 is greater than that of the first mask pattern region 10.

It should be noted that the mask of the embodiment of the present application further includes a second mask pattern region 40, and since the spacer includes a main spacer and an auxiliary spacer, the first mask pattern region 10 and the second mask pattern region 40 are simultaneously disposed on the mask, so that the main spacer and the auxiliary spacer can be simultaneously manufactured by the mask at one time, thereby improving the manufacturing efficiency of the spacer and saving the manufacturing cost.

The light transmittance of the second mask pattern area 40 is set to be greater than that of the first mask pattern area 10, so that the height of the spacer manufactured correspondingly to the second mask pattern area 40 is higher than that of the spacer manufactured correspondingly to the first mask pattern area 10, which is equivalent to that when the mask of the present application is adopted to manufacture the spacer, the second mask pattern area 40 is aligned to the position where the main spacer is to be manufactured, and the first mask pattern area 10 is aligned to the position where the auxiliary spacer is to be manufactured, so that the main spacer and the auxiliary spacer with height difference can be manufactured at one time, compared with the existing mask, only the main spacer and the auxiliary spacer with the same height can be manufactured, and then the height of the main spacer is increased to the metal block under the main spacer, the mask of the present application can directly manufacture the main spacer and the auxiliary spacer with height difference, and does not need additional metal blocks, not only saves the cost, but also reduces the manufacturing difficulty of the spacer.

Optionally, in the mask according to the first to fourth embodiments of the present application, the second mask pattern region 40 is a full light-transmitting hole.

It is understood that the transmittance of the first mask pattern region 10 is decreased in the first direction in this application, so that the transmittance of the first mask pattern region 10 is less than 100%, and at this time, the second mask pattern region 40 is set to be the full transmittance hole, that is, the transmittance of the second mask pattern region 40 is set to be 100%, and at this time, the transmittance of the second mask pattern region 40 is satisfied as being greater than the transmittance of the first mask pattern region 10.

It should be noted that, when the mask of the present application is used to manufacture spacers, the shape of the main spacer manufactured corresponding to the first mask pattern area 10 is circular truncated cone-shaped, and the shape of the auxiliary spacer manufactured corresponding to the second mask pattern area 40 is circular truncated cone-shaped, which is approximately cylindrical, and since the number ratio of the main spacer to the auxiliary spacer existing in the liquid crystal display panel is approximately 2 to 70, the area of the top of the auxiliary spacer manufactured by the mask of the present application is increased, thereby eliminating the problem that the display panel is pierced when the top of the spacer is too sharp, and even if the area of the top of the circular truncated cone-shaped main spacer manufactured corresponding to the first mask pattern area 10 is too small, the display panel is not pierced easily because the number of the main spacers is small.

Optionally, since the height of the spacer is related to the light transmittance of the exposure, and the light transmittance area of the exposure affects the thickness of the spacer, the shape of the second mask pattern region 40 included in the mask of the present application may be rectangular, circular, regular pentagonal, or polygonal shape larger than five sides. The embodiment of the application is not limited, as long as the second mask pattern area 40 is a full light-transmitting hole, the light transmittance of the second mask pattern area 40 can be ensured to be 100%, and the light transmittance of the second mask pattern area 40 can be ensured to be greater than that of the first mask pattern area 10, so that the main spacer and the auxiliary spacer obtained by exposure manufacture have certain height difference.
