The present application is described in detail below with reference to the figures and alternative embodiments.
Fig. 1 is a schematic diagram of an embodiment of a display device according to the present application, and as shown in fig. 1, the present application discloses a display device 10 including a backlight module 200 and a display panel 100, wherein the backlight module 200 is disposed on one side of a light incident surface of the display panel 100.
The general display panel 100 does not emit light, and the backlight module 200 is needed to provide a light source for the display panel 100, so that the display panel 100 displays normally, a liquid crystal layer 190 is placed between the upper and lower substrates of the display panel 100, and the driving voltage is applied to the two glass substrates to control the liquid crystal molecules to change the direction, so as to refract the light of the backlight module 200 to generate a picture; in the middle-stage box-forming process of the display panel 100, a layer of alignment film 160 is usually formed on the two substrates, the alignment film 160 is usually made of polyimide, and then frame glue is coated and liquid crystal is dropped; in order to effectively support the two layers of substrates after the two substrates are used for packaging, a spacer structure 150 is arranged between the two substrates, the two substrates are attached in a vacuum state, and finally the frame glue is cured through ultraviolet irradiation to finish packaging the box.
The display device 10 of the present application may be: any product or component having a display function, such as a liquid crystal television, a liquid crystal display, a digital photo frame, a mobile phone, a tablet computer, etc., is not particularly limited, and the liquid crystal display device 10 is merely exemplified in the present application.
The application of the display device 10 is that when receiving external force extrusion or carrying out pressure test, the spacer structure 150 receives the bending under the pressure effect and forms the displacement, carries out spacing to the spacer structure 150 more easily, and the effectual alignment film 160 that prevents the effective display area of spacer structure 150 fish tail has guaranteed display device 10's yields and life.
The present application specifically resides in an improvement of the display panel 100 in the display device 10:
fig. 2 is a schematic diagram of a first embodiment of a display panel of the present application, and as shown in fig. 2, the present application discloses a display panel 100, which includes a first substrate 110, a second substrate 120, and a spacer structure 150, wherein the first substrate 110 and the second substrate 120 are arranged in a pair, the spacer structure 150 is arranged between the first substrate 110 and the second substrate 120, one end of the spacer structure 150 is fixed on the first substrate 110, and the other end abuts against the second substrate 120; the accommodating groove structure 180 is disposed on a side of the second substrate 120 close to the first substrate 110, and a portion of an orthographic projection of the spacer structure 150 on the second substrate 120 overlaps with an orthographic projection of the accommodating groove structure 180 on the second substrate 120.
In the present application, the receiving groove structure 180 is disposed on the second substrate 120, such that the projection areas of the receiving groove structure 180 and the spacer structure 150 in the positive direction on the second substrate 120 are partially overlapped, and when the spacer structure 150 is under pressure, the center of gravity of the spacer structure 150 is more easily inclined toward the receiving groove structure 180, such that the spacer structure 150 is more easily dropped into the receiving groove structure 180 when sliding, and is limited by the receiving space formed by the receiving groove structure 180, such that the spacer structure 150 is not scratched to other positions of the display panel 100, thereby preventing the spacer structure 150 from sliding toward the effective display area of the display panel 100 to scratch the alignment film 160 of the effective display area, and meanwhile, the spacer structure 150 in the present application is not in direct contact with the receiving groove structure 180 after the first substrate 110 and the second substrate 120 are aligned to the box, thereby preventing the display panel 100 from being under pressure, the spacer structure 180 directly stands at the bottom of the accommodating groove structure 180, and the bottom of the accommodating groove structure 180 is uneven, so that the problem of uneven box thickness of the display panel 100 caused by uneven supporting height of the spacer structure 180 can be solved, and the stable and even box thickness can be maintained; the spacer structure 150 and the receiving groove structure 180 are partially overlapped, so that the influence on the aperture ratio can be reduced; the display effect and the yield of the display panel 100 are further improved.
As shown in fig. 2, the first substrate 110 is a color filter substrate 130, the second substrate 120 is an array substrate 140, the array substrate 140 is disposed on a side close to the light incident surface of the display panel 100, the color filter substrate 130 is disposed on a side of the light emergent surface of the display panel 100, and the accommodating groove structure 180 is disposed on a side of the array substrate 140 facing the color filter substrate 130.
When the first substrate 110 is the color filter substrate 130 and the second substrate 120 is the array substrate 140, the array substrate 140 is closer to the backlight module 200, the color filter substrate 130 is disposed above the array substrate 140, the receiving groove structure 180 is disposed on the array substrate 140, one end of the spacer structure 150 is fixed on the color filter substrate 130, the other end of the spacer structure 150 abuts against the array substrate 140, and one end of the spacer structure 150 abutting against the array substrate 140 overlaps with a projection of the receiving groove structure 180 in a positive direction on the array substrate 140, that is, when the spacer structure 150 abuts against the array substrate 140, a part of the spacer structure 150 is directly above the receiving groove structure 180.
When the display panel 100 is pressed, the spacer structure 150 is pressed, and during the pressing, the spacer structure 150 slides on the array substrate 140 to release the stress,
because some of the spacer structures 150 are suspended over the receiving groove structure 180, when the spacer structures 150 slide, they are more easily inclined toward the receiving groove structure 180, and the ends of the spacer structures 150 abutting against the array substrate 140 are more easily dropped into the receiving groove structure 180, so that the spacer structures 150 can only move in the space formed by the receiving groove structure 180, and cannot slide continuously toward the display area, thereby preventing the spacer structures 150 from scratching the alignment film 160 in the display area, preventing the alignment film 160 from being scratched by the spacer structures 150, preventing the liquid crystal molecules at the scratched alignment film 160 from deflecting normally, resulting in light leakage or blue spots, and affecting the display effect. By the arrangement, the display effect of the display panel 100 is ensured, and the yield of the display panel 100 is improved.
Meanwhile, the spacer structure 150 in the present application is after the color film substrate 130 and the array substrate 140 are aligned, the spacer structure 150 is not directly abutted to the inside of the receiving groove structure 180, but stands on the flat layer of the array substrate 140, thus the surface against which the spacer structure 150 abuts is very flat, thereby avoiding the problem that the thickness of the display panel 100 is uneven due to the fact that the spacer structure 180 directly stands at the bottom of the receiving groove structure 180 when the display panel 100 is not under the action of pressure, and the bottom of the receiving groove structure 180 is uneven, so that the supporting height of the spacer structure 180 is uneven, and the resulting thickness of the display panel 100 is uneven, and maintaining the stable and even thickness of the box.
In the present application, the spacer structure 150 is abutted to one end of the array substrate 140 to expose the receiving groove structure 180, and the width of the receiving groove structure is between one third and three quarters of the total width.
When the width of the spacer structure 150, which is exposed out of the receiving groove structure 180 at one end of the array substrate 140 and abuts against the array substrate, is one third of the total width, most of the spacer structure 150 is located right above the receiving groove structure 180, and when the spacer structure 150 slides under the action of an external force, the center of gravity of the spacer structure 150 is more easily inclined toward the receiving groove structure 180, so that the spacer structure 150 is more easily slid into the receiving groove structure 180, the movement of the spacer structure 150 is limited in the receiving space formed by the receiving groove structure 180, the alignment film 160 in the display area is not scratched, and the display effect of the display panel 100 is further ensured;
when one end of the spacer structure 150 abutting against the array substrate 140 exposes three-fourths of the total width of the receiving groove structure 180, most of the spacer structure 150 directly abuts against the array substrate 140, the range of the spacer structure 150 supported on the array substrate 140 is larger, after the color film substrate 130 and the array substrate 140 are paired, the two substrates can be better supported, deformation of the two substrates is prevented, the structure of the display panel 100 is more stable, meanwhile, when the display panel 100 is subjected to an external force, the spacer structure 150 is pressed to cause bending of the spacer to generate displacement, the spacer structure 150 can be easily made to slide into the receiving groove structure 180, the spacer structure 150 is prevented from sliding towards the display area to cause scratching of the alignment film 160 of the display area, the display effect is further ensured, and the yield of the display panel 100 is further ensured.
Further, when the spacer structure 150 abuts against one end of the array substrate 140 and the width of the receiving groove structure 180 is exposed out of one half of the total width, at this time, one half of the spacer structure 150 is located right above the receiving groove structure 180, and the other half abuts against the array substrate 140, so that the center of gravity of the spacer structure 150 is relatively balanced, and under the condition of good supporting stability, the spacer structure 150 can slide under the action of an external force, and the center of gravity of the spacer structure 150 is more easily inclined towards the receiving groove structure 180, so that the spacer structure 150 is more easily sunk into the receiving groove structure 180, and the spacer structure 150 can only move in the receiving groove structure 180 and cannot slide to the display area, and further can not scratch the alignment film 160 of the display area, and under the condition of ensuring effective support of the upper and lower substrates, the spacer structure can more easily slide into the receiving groove structure 180, two purposes are achieved at one stroke.
As shown in fig. 2, the array substrate 140 includes a thin film transistor 188 and a pixel electrode 187, the thin film transistor 188 includes a drain electrode 189 and a passivation layer 141, the receiving groove structure 180 includes a via hole 181, and the via hole 181 is disposed on the passivation layer 141 to connect the drain electrode 189 and the pixel electrode 187, and is located between the spacer structure 150 and the pixel electrode 187; the width of the opening of the via 181 on the passivation layer 141 is greater than the width of one end of the spacer structure 150 abutting the array substrate 140.
The receiving groove structure 180 can be a via hole 181 formed on the passivation layer 141 of the tft 188 of the array substrate 140, an inherent structure formed during the manufacturing process of the array substrate 140 is used as the receiving groove structure 180, and the location of the via hole 181 is located between the spacer structure 150 and the pixel area 186, when the display panel 100 is pressed against the spacer structure 150, because the via hole 181 is formed between the pixel area 186 and the spacer structure 150, the spacer structure 150 will fall into the via hole 181 and be limited in the receiving space formed by the via hole 181 when sliding towards the pixel area 186, thereby preventing the spacer structure 150 from further sliding towards the pixel area 186 to scratch the alignment film 160 of the pixel area 186, ensuring the display effect, and meanwhile, the via hole 181 of the array substrate 140 itself is used as the receiving groove structure 180, and the limitation of the spacer structure 150 can be realized without adding a structure on the array substrate 140 additionally, the manufacturing process is reduced, and the cost is saved. In addition, in the limited space on the array substrate 140, the spacer structure 150 is limited by the via hole 181 formed during the fabrication of the thin film transistor 188, and no other limiting structure is provided on the array substrate 140, so that the condition that the transparent area on the array substrate 140 is blocked or the transparent area needs to be reduced to design other limiting structures can be effectively prevented. It is advantageous to increase the aperture ratio of the display panel 100.
Further, the spacer structure 150, the via hole 181 and the pixel region 186 may be on the same straight line, and the spacer structure 150 is far away from the pixel region 186.
The spacer structure 150 is placed at a position where the via hole 181 and the pixel area 186 are in a straight line and far away from the pixel area 186, and the via hole 181 is located on a path where the spacer structure 150 slides to the pixel area 186, when the spacer structure 150 is under pressure, even if the spacer structure 150 slides, the spacer structure will slide to the pixel area 186 and fall into the via hole 181, and the via hole 181 can limit the spacer structure 150 in an area formed by the via hole 181, fix the spacer structure and prevent the spacer structure from sliding to the pixel area 186. Therefore, when the spacer structure 150 slides towards the pixel area 186 under the action of pressure, the spacer structure 150 can more accurately fall into the via hole 181 and is limited by the via hole 181, so that the spacer structure 150 is prevented from further sliding towards the pixel area 186, the alignment film 160 of the pixel area 186 is prevented from being scratched by the spacer structure 150 more efficiently, and the display effect of the display panel 100 and the yield of the display panel 100 are ensured.
In addition, the via hole 181 may be further disposed on a side of the spacer structure 150 away from the pixel area 186, such that the sliding probability of the spacer structure 150 toward the pixel area 186 may be reduced, so that when the spacer structure 150 slides toward the direction away from the pixel area 186, the sliding is converted into the case of scratching the via hole 181, the possibility of scratching the pixel area 186 by the spacer structure 150 is reduced, the number of times of scratching the pixel area 186 by the spacer structure 150 is greatly reduced, and the case of scratching the alignment film 160 due to frequent sliding of the spacer structure 150 is reduced.
The via hole 181 in this application may also be a via hole 181 of other devices such as an optical sensor, and the like, and the normal function of the display panel is not affected, and the present invention is not particularly limited.
The width of the opening of the via hole 181 on the passivation layer 141 is greater than the width of one end of the spacer structure 150 abutting against the array substrate 140, so that the spacer structure 150 can be better sunk into the via hole 181 for limiting when sliding occurs. The opening of the via hole 181 may be made large when the via hole 181 is formed, or the width of the spacer structure 150 abutting against one end of the array substrate 140 may be made narrow, which can achieve the above-mentioned effects, and is not described in detail herein.

The receiving groove structure 180 can also be a groove 182 formed on each film layer of the thin film transistor 188, the groove 182 formed in the manufacturing process of the array substrate 140 is used as the receiving groove structure 180, and the position of the groove 182 is located between the spacer structure 150 and the pixel area 186, when the display panel 100 is pressed to press the spacer structure 150, because the groove 182 is formed between the pixel area 186 and the spacer structure 150, the spacer structure 150 will fall into the groove 182 first and be limited in the receiving space formed by the groove 182 even if sliding towards the pixel area 186, thereby preventing the spacer structure 150 from further sliding towards the pixel area 186 to scratch the alignment film 160 of the pixel area 186, ensuring the display effect, meanwhile, the groove 182 of the array substrate 140 itself is used as the receiving groove structure 180, and the limitation of the spacer structure 150 can be realized without additionally adding a structure on the array substrate 140, the manufacturing process is reduced, and the cost is saved.
In addition, in the limited space on the array substrate 140, the spacer structure 150 is limited by the channel 182 formed when the thin film transistor 188 is manufactured, and no other limiting structure is provided on the array substrate 140, so that the situation that the light-transmitting area on the array substrate 140 is blocked or the other limiting structure can be designed only by reducing the light-transmitting area can be effectively prevented. It is advantageous to increase the aperture ratio of the display panel 100.
The spacer structure 150 has a width less than the width of the channel 182 at an end abutting the array substrate 140. The spacer structure 150 can be better sunk into the channel 182 for limiting when sliding occurs. The width of the channel 182 may be made wide when the channel 182 formed by each film layer is manufactured, or the width of the spacer structure 150 abutting against one end of the array substrate 140 may be made narrow, which may all achieve the above-mentioned effects, and is not described in detail herein.
Fig. 4 is a schematic diagram of a third embodiment of the display panel of the present application, as shown in fig. 4, the embodiment shown in fig. 4 is based on the improvement of fig. 2, the accommodating groove structure 180 includes a groove 183, the array substrate 140 includes a passivation layer 141, the groove 183 is disposed on the passivation layer 141, and the groove 183 is formed by recessing the passivation layer 141 from a side close to the color filter substrate 130 to a side away from the color filter substrate 130; and the width of the groove 183 is smaller than the width of the spacer structure abutting against one end of the array substrate 140.
In this embodiment, the groove 183 is additionally dug on the passivation layer 141 of the array substrate 140, so that when the display panel 100 is under pressure, the spacer structure 150 is bent, the spacer structure 150 slides in the process of releasing stress, and the center of gravity inclines towards the direction of the groove 183, so that the spacer structure 150 slides into the groove 183 more easily, and is limited in the accommodating space formed by the groove 183, thereby further preventing the spacer structure 150 from sliding towards the pixel area 186, and preventing the spacer structure 150 from scratching the alignment film 160 of the pixel area 186, which causes abnormal display.
In addition, in the spacer structure 150 in this application, after the color film substrate 130 and the array substrate 140 are aligned, the spacer structure 150 is not directly abutted to the groove 183 but stands on the passivation layer 141 of the array substrate 140, so that the abutting surface of the spacer structure 150 is very flat, and the problem that when the display panel 100 is not stressed, the spacer structure 180 directly stands at the bottom of the groove 183, and the bottom of the groove 183 is uneven, so that the supporting height of the spacer structure 180 is uneven, and the thickness of the display panel 100 is uneven is avoided, and the stable and even thickness of the box can be maintained.
The width of the groove 183 is smaller than the width of the top end of the spacer structure 150, so that when the spacer structure 150 slides, a part of the spacer structure 150 is clamped into the groove 183, when the stress on the display panel 100 is relieved, the spacer structure 150 returns to the original state from the bending state to generate elasticity, and when the spacer rebounds, a part of the spacer structure is clamped into the groove 183, so that a part of the spacer structure is still outside the groove 183, and the spacer structure 150 rebounds to return to the position of the passivation layer 141 to effectively support the color film substrate 130 and the array substrate 140 again.
The groove 183 of the present application may be a circular groove 183, a square groove 183, or a groove 183 of other shapes, and is not limited specifically, and only has a space enough to accommodate the spacer structure 150.
In the present application, the side of the recess 183 adjacent to the spacer structure 150 is an arcuate chamfer 185 or a straight chamfer 184. The method comprises the following specific steps:
fig. 5 is a schematic diagram of a fourth embodiment of the display panel of the present application, as shown in fig. 5, when one side of the groove 183 close to the spacer structure 150 is a straight chamfer 184, when the display panel 100 is under pressure, the spacer structure 150 is squeezed, so that the spacer structure 150 is bent, and when the spacer structure 150 releases the stress, the spacer structure slides along the contact surface with the passivation layer 141 of the array substrate 140, and during the process of sliding into the groove 183, one end of the spacer structure 150 abutting against the array substrate 140 slides along the straight chamfer 184, and the straight chamfer 184 makes the spacer structure 150 slide into the bottom of the groove 183 more easily during sliding, so that the spacer structure 150 sinks into the groove 183 more easily. Therefore, the groove 183 can better limit the spacer structure 150, prevent the spacer structure 150 from sliding to the pixel area 186 and scratch the alignment film 160 in the pixel area 186, and ensure the display effect of the display panel 100.
In addition, when the pressure of the display panel 100 is released, the spacer structure 150 may be restored to the original state from the bent state, and the elastic force may be released in the process, and the arc-shaped chamfer 185 may enable the spacer structure 150 to be more easily restored to the original position by being rebounded obliquely upward through the straight line of the straight chamfer 184 when the elastic force is released, and be fixed on the passivation layer 141 again, thereby ensuring the structural stability of the display panel 100.

In addition, when the pressure of the display panel 100 is relieved, the spacer structure 150 can be restored to the original state from the bent state, the elastic force can be released in the process, the arc-shaped chamfer 185 can enable the spacer structure 150 to be more easily restored to the original position by rebounding through the arc of the arc-shaped chamfer 185 when the elastic force is released, the spacer structure is fixed on the passivation layer 141 again, the structural stability of the display panel 100 is guaranteed, and the use experience of the display panel 100 is improved.

For example, when the chamfer of the side of the groove 183 close to the spacer structure 150 is a straight chamfer 184, the corresponding chamfer structure 151 of the side of the spacer structure away from the groove 183 is also a straight chamfer 184, and the two chamfers are matched with each other, when the display panel 100 is subjected to external pressure or pressure test, the spacer structure 150 is squeezed, the spacer structure 150 bends to slide along the passivation layer 141 of the array substrate 140, firstly, the contact surface between the spacer structure 150 and the passivation layer 141 slides, when the display panel slides into the groove 183 gradually, the chamfer of the spacer structure 150 originally away from the groove 183 gradually approaches the groove 183, until the spacer structure 150 is about to fall into the groove 183 completely, the chamfer structure 151 on the spacer structure 150 is matched with the straight chamfer 184 of the groove 183, so that the spacer structure 150 falls into the groove 183 more smoothly and more stably, and display abnormality of the display panel 100 is not caused, meanwhile, the spacer structure 150 slides into the groove 183 more smoothly, and the stability of the overall structure of the display panel 100 is ensured.
Moreover, after the pressure of the display panel 100 is released, the spacer structure 150 releases the stress from the bent state to recover to the original state, and has elasticity in the recovery process, when the chamfer structure 151 on the spacer structure 150 is matched with the chamfer shape of the groove 183, the spacer structure 150 is more easily popped out from the groove 183, so that the spacer structure 150 returns to the original state again, the structural stability of the display panel 100 is ensured, the yield of the display panel 100 is improved, and the use experience of the display panel 100 is further improved.

After the limiting member 170 is disposed, when the spacer structure 150 is forced to slide, if the spacer structure slides in a direction away from the receiving groove structure 180, the spacer structure 150 is abutted by the limiting member 170, so as to prevent the spacer structure 150 from further sliding in a direction away from the groove 183, so that the spacer structure 150 can only slide in a position where the receiving groove structure 180 is located, and the spacer structure 150 can more easily slide into the receiving groove structure 180 to play an auxiliary role.

When the display panel 100 is pressed, the spacer structure 150 is pressed to slide, the upward end of the spacer structure 150 slides on the array substrate 140, and slides into the groove 183, and is limited by the accommodating space formed by the groove 183, the spacer structure 150 can only move in the groove 183 and cannot be scratched to the pixel area 186, and thus the alignment film 160 of the pixel area 186 cannot be scratched, and the situation that the display is abnormal because the alignment film 160 of the pixel area 186 is scratched, and the liquid crystal molecules of the scratched alignment film 160 cannot be deflected normally is avoided.
