The present application will now be described in detail with reference to the drawings and alternative embodiments, it being understood that any combination of the various embodiments or technical features described below may form new embodiments without conflict.
As shown in fig. 1, a schematic diagram of a display device 100 is shown. As an embodiment of the present application, a display device 100 is disclosed, the display device 100 including a display panel 200 and a driving circuit 300 driving the display panel 200. As shown in fig. 2, the schematic diagram of a display panel 200 is shown, where the display panel 200 includes an array substrate 220 and a color filter substrate 210 that are arranged in a box-to-box manner, the color filter substrate 210 includes a film substrate, a black matrix layer 212 and a groove 214, the color filter substrate 211 includes a display area and a non-display area, and the non-display area is arranged around the display area; the black matrix layer 212 is disposed on one side of the color filter substrate 211 close to the array substrate 220, and at least includes a first black matrix layer 213 formed in the non-display area; the groove 214 is disposed on the first black matrix layer 213, penetrates through the first black matrix layer 213, and cuts off the first black matrix layer 213; the array substrate 220 includes a first light-shielding layer 222, and an orthographic projection of the first light-shielding layer 222 covers the groove 214.
With the improvement of the appearance requirement of display screen products, ebl (entry border) technology is mostly adopted to produce products in the market, that is, the products are designed without a frame, but the light leakage problem at the edge is brought at the same time. The existing design is to increase the size of the color film substrate glass, so that the black matrix layer is flush with the edge of the color film substrate. The design utilizes the black matrix layer to realize the light blocking effect of the edge, so as to achieve better user experience. However, the design can expose the black matrix layer too much (close to the edge of the glass), so that the black matrix layer on the color film substrate corresponds to the peripheral metal signal lines on the array substrate, and when the display panel works, the black matrix can generate induced voltage to generate Static electricity to influence liquid crystal deflection, so that the risk of Electro-Static discharge (ESD) is greatly increased, and the product performance is reduced. At present, static electricity is prevented from being transferred into a display area by mostly disconnecting a black matrix in a non-display area; however, this may cause a risk of light leakage, which may affect the display effect of the product.
The groove 214 is formed in the first black matrix layer 213 in the non-display area, and the groove 214 cuts off the first black matrix layer 213, so that static electricity is prevented from being transmitted into the display area along the black matrix, and deflection of liquid crystals is prevented from being influenced. A first light shielding layer 222 corresponding to the groove 214 is further disposed on the array substrate 220, that is, the first light shielding layer 222 is disposed on the light incident side; this application prevents through first light shield layer 222 that the light leak that the backlight produced from permeating through glass substrate, can effectively prevent because backlight light incident angle is great, has the light leak that the light caused in getting into recess 214.
Further, the color filter substrate 210 further includes a second light-shielding layer 215, the second light-shielding layer 215 is disposed on a side of the color filter substrate 211 away from the array substrate 220, and an orthogonal projection of the second light-shielding layer 215 covers the groove 214 and is partially overlapped with the first black matrix layer 213.
In the present application, a second light-shielding layer 215 and a first light-shielding layer 222 are disposed on two sides of the groove 214, the second light-shielding layer 215 is located on one side of the color film substrate 211 away from the array substrate 220, the first light-shielding layer 222 is disposed on the array substrate 220, that is, the second light-shielding layer 215 is disposed on the light-emitting side, and the first light-shielding layer 222 is disposed on the light-entering side; compared with the scheme of arranging the light shielding layer on only one side of the groove 214, the light leakage generated by the backlight source is prevented from transmitting through the glass substrate by the first light shielding layer 222, and the light entering the grooving position is prevented from transmitting through the glass substrate by the second light shielding layer 215; can effectively prevent because backlight light incident angle is great, perhaps be close to in the liquid crystal layer that there is the light leak that leads to the fact in recess 214 groove 214 that light gets into in the position department, consequently this application can provide good light shading effect. In addition, the second light-shielding layer 215 covers the groove 214 and the black matrix around the groove 214, so as to prevent light leakage in the groove 214 from being observed through the color film substrate 211 by the human eye due to the problem of viewing angle, thereby further enhancing the light leakage prevention effect of the display panel 200.
Fig. 3 is a schematic diagram of a color filter substrate 210. The second light shielding layer 215 covers the groove 214 and the black matrix around the groove 214, specifically, the second light shielding layer 215 overlaps the first black matrix layer 213 on both sides of the groove 214 to form a first overlapping region 218 and a second overlapping region 219, and the width of the first overlapping region 218 and the second overlapping region 219 is D × tan α; wherein D is the thickness of the color film substrate 211, and α is the difference between the product visual angle and 90 °. When a user views the screen, if the user is in a side view but the side view angle is smaller than the viewing angle, the light leakage phenomenon is not observed from the gap between the first black matrix layer 213 and the second light shielding layer 215 in the non-display region.
Specifically, the groove 214 may be an end-to-end annular structure disposed around the display region, which can sufficiently separate the first black matrix layer 213 in the non-display region, so as to prevent static electricity from being introduced into the black matrix in the periphery; of course, the groove 214 may also be another structure capable of blocking the first black matrix layer 213, and is not limited herein. The width of the groove 214 can be set to be 2-3 times of the minimum gap of metal wiring in the display panel 200, and because the width requirements of the non-Gate Drive (GDL) areas of the panels with different sizes are different, designers have considered whether the line width of each wiring line can meet the overvoltage capability and the distance can meet the creepage distance requirement, so that the width of the groove 214 is set to be 2-3 times of the minimum gap of wiring in the panel, the width of the groove 214 is smaller, and the light leakage risk is reduced. Of course, the width of the groove 214 may also be set to be 1-2 times of the width of the data line, so that the width of the groove 214, the width of the second light shielding layer 215 and the width of the first light shielding layer 222 can be matched with the processing precision of the equipment while the size is small, and the processing difficulty is reduced.
The second light-shielding layer 215 is made of a blue resist material, and the first light-shielding layer 222 is made of a red resist material; after the two light shielding layers formed by the color resistors with different colors are stacked, the light shielding condition can be met, human eyes are insensitive to blue, and after the second light shielding layer 215 is set to be blue, even if light leakage occurs, the second light shielding layer 215 cannot be distinguished by human eyes. Of course, the second light-shielding layer 215 and the first light-shielding layer 222 may be made of light-shielding materials such as photo-resist, or any other two color-resisting materials with different colors.
As shown in fig. 4, which is a schematic view of another display panel 200, as another embodiment of the present disclosure, the color filter substrate 210 further includes a planarization layer 216 and a polarizer 217 besides the color filter substrate 211, the second light-shielding layer 215 and the black matrix layer 212, the planarization layer 216 is disposed on the second light-shielding layer 215, and the planarization layer 216 is flush with an edge of the color filter substrate 211; the polarizer 217 is arranged on one side of the flat layer 216 far away from the color film substrate 211; the flat layer 216 is disposed to prevent the second light-shielding layer 215 and the polarizer 217 from being worn out, which may cause film layer abnormality. The thickness of the flat layer 216 exceeds the thickness of the second light-shielding layer 215 by 0.1-0.2um, so that the surface height of the whole flat layer 216 is relatively flat, and the whole flat layer is not affected even if the position overlapped with the second light-shielding layer 215 is slightly protruded. Specifically, the thickness of the second light-shielding layer 215 is 0.5um, the thickness of the flat layer 216 is 0.6, and the flat layer 216 may be made of an indium tin oxide material; the ito material itself has a certain anti-wear effect, and since the final product has a polarizer 217 attached to the outermost layer to just protect the second light-shielding layer 215 and the flat layer 216, no other design specific to material wear is required.
As shown in fig. 5 and fig. 6, which are schematic plan views of an array substrate 220 and a color filter substrate 210, as another embodiment of the present application, the present application further designs an alignment mark 224 on the basis of a light-shielding layer, so as to achieve the technical effect of achieving multiple purposes. Specifically, the display panel 200 includes an array substrate 220 and a color film substrate 210 which are arranged in a box-to-box manner, the color film substrate 210 includes a color film substrate 211, a black matrix layer 212, a groove 214 and a second light shielding layer 215, the color film substrate 211 includes a display area and a non-display area, and the non-display area is arranged around the display area; the black matrix layer 212 is disposed on one side of the color filter substrate 211 close to the array substrate 220, and at least includes a first black matrix layer 213 formed in the non-display area; the groove 214 is disposed on the first black matrix layer 213, penetrates through the first black matrix layer 213, and cuts off the first black matrix layer 213; the second light shielding layer 215 is disposed on a side of the color filter substrate 211 away from the array substrate 220, and an orthogonal projection of the second light shielding layer 215 covers the groove 214 and is partially overlapped with the first black matrix layer 213; the array substrate 220 includes a first light-shielding layer 222, and an orthographic projection of the first light-shielding layer 222 covers the groove 214.
The second light shielding layer 215 is made of a blue color resist material, the first light shielding layer 222 is made of a red color resist material, the first light shielding layer 222 includes a mark portion 224 and a light shielding portion 223, the light shielding portion 223 overlaps with the groove 214, and the mark portion 224 overlaps with the first black matrix layer 213; the first black matrix layer 213 includes a hollow pattern 225, and the hollow pattern 225 and the mark portion 224 have the same orthographic projection shape, i.e., the same pattern, and are disposed correspondingly.
In this way, in the alignment detection, whether the color filter substrate 210 or the array substrate 220 is viewed from the side, the alignment of the array substrate 220 and the color filter substrate 210 can be known by observing whether the mark portion 224 of the first light-shielding layer 222 and the hollow pattern 225 of the first black matrix layer 213 are overlapped. It should be noted that, during the alignment observation, the process of the first light-shielding layer 222 is not performed, and the corresponding process of the first light-shielding layer 222 can be performed only after the alignment is completed, and at this time, the first light-shielding layer 222 can also shield the light leakage of the hollow pattern 225.
