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, which is a schematic view of a display panel, as an embodiment of the present application, a display panel 100 is disclosed, where the display panel 100 includes an array substrate 300 and a color filter substrate 200 that are arranged in a box-to-box manner. As shown in fig. 2, the color filter substrate 200 is a schematic diagram of the color filter substrate 200, where the color filter substrate 200 includes a substrate 210, a black matrix layer 220, two first grooves 230, and two second grooves 240, the substrate 210 includes a display area 211 and a non-display area 212, the non-display area 212 is disposed around the display area 211, and the black matrix layer 220 is disposed in the non-display area 212 of the substrate 210; the first grooves 230 are disposed in the black matrix layer 220 and located on the viewing side of the color film substrate 200 respectively; the second grooves 240 are disposed in the black matrix layer 220 and located on the non-observation side of the color film substrate 200 respectively; the two first grooves 230 and the two second grooves 240 are connected end to form a ring shape, and the width of the second grooves 240 is greater than that of the first grooves 230.
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. In the conventional design, the size of the glass of the color filter substrate 210 is increased, so that the black matrix layer 220 is flush with the edge of the color filter substrate 210. This design utilizes the black matrix layer 220 to achieve the light blocking effect of the edge to achieve a better user experience. However, the design may cause the black matrix layer 220 to be excessively exposed (close to the edge of the glass), so that the black matrix on the color film substrate 200 corresponds to the peripheral metal signal lines on the array substrate 300, and when the display panel 100 operates, the black matrix layer 220 may generate induced voltage to generate Static electricity, which affects liquid crystal deflection, thereby greatly increasing the risk of ESD (Electro-Static discharge) and reducing the performance of the product. At present, static electricity is prevented from being transferred into the display region 211 by mostly disconnecting the black matrix layer in the non-display region 212; however, this may cause a risk of light leakage, which may affect the display effect of the product.
In the application, a circle of annular grooves are arranged in the black matrix of the non-display area 212, and the widths of the peripheries of the annular grooves are different; when a user watches the display screen, due to the observation angle, the attention of human eyes to the observation side is more concentrated, and the user can be easily observed when light leakage occurs on the observation side; therefore, the width of the second groove 240 on the non-observation side is greater than that of the first groove 230 on the observation side, the width of the first groove 230 on the observation side is smaller and is not easy to observe, and light leakage caused by light sensitivity of human eyes on the observation side is avoided; the width of the second groove 240 on the non-observation side is larger but not easy to attract the attention of the user, and the distance between the black matrixes on the two sides of the second groove 240 is increased; therefore, the light leakage is prevented, and the antistatic effect is further increased.
It should be noted that the viewing side is one side or multiple sides with a large variation range and a non-fixed viewing angle (e.g. 0 to 180 °) when the display panel is used, and the viewing angle of the viewing side is relatively large (e.g. 90 ° or has a small variation range), while the viewing angle of the non-viewing side is relatively fixed. The common observation sides of the current common televisions and computers are the left side and the right side; in some use environments, however, the upper and lower sides of the display screen serve as viewing sides.
Specifically, the width of the first groove 230 is 1-10um, and the width of the second groove 240 is 15-40 um. When the width of the groove is less than 1um, the process deviation is large, and the groove digging cannot be accurately realized; metal wires (including peripheral metal signal wires) in the array substrate corresponding to the grooves are generally wider and can be used for blocking light, and light leakage can be caused if the width of the grooves is continuously widened along with the increase of the visual angle at the observation side; because the width of present liquid crystal box is 3-6um, the width of the metal of walking in the array substrate that corresponds is generally 40um, still will consider the light refraction that the difference of materials such as insulating layer, liquid crystal box on the metal walks in addition leads to, based on many-sided consideration, the width of this application with observation side cut groove department sets for being less than 10um, if the width of observation side cut groove department is greater than when 10um, has the light leak risk in big visual angle direction. On the non-observation side, because of the observation angle, the light leakage of the region is not easy to be perceived by human eyes, so the width of the digging groove can be increased; however, when the width of the metal trace exceeds the width of the metal trace in the array substrate at the corresponding position, and the width of the groove is increased, the risk of light leakage is increased, so that the width of the BM groove at the non-observation side is limited to 15-40 um.
The first groove 230 is a through groove, and the second groove 240 is a blind groove; when the first groove 230 penetrates through the black matrix layer 220 in the first direction, the first groove 230 is a through groove, and when the second groove 240 does not penetrate through the black matrix layer 220 in the first direction, the second groove 240 is a blind groove, and the first direction is the thickness direction of the black matrix layer 220. Because the width of the first groove 230 is small and the light transmission amount is small, the first groove 230 is a through groove to block the charge transmission, so that the static electricity can be effectively prevented; because the width of the second groove 240 is large, although the anti-static effect can be enhanced, the width is large, and the light leakage risk is easily caused, so that the second groove 240 is set as a blind groove, and the light leakage problem caused by the blind groove can be prevented. The thickness of the black matrix below the second groove 240 is 0.7-0.9um, as shown in fig. 3, which is a schematic diagram of the variation of the resistance and the OD value with the thickness of the black matrix layer 220, and it can be seen from the diagram that when the thickness of the black matrix layer 220 increases, the resistance gradually decreases, and the OD value gradually increases.
As can be seen from the OD curve in the figure, when the OD value is greater than 4, the black matrix layer 220 has a good light-shielding effect, and the thickness of the black matrix layer 220 is 0.7um, so that the thickness of the black matrix layer 220 is not less than 0.7um to ensure that the color filter substrate 200 does not leak light; it can be known from the resistance curve in the figure that when the thickness of the black matrix layer 220 exceeds 0.9um, the resistance thereof reaches a degree close to saturation, and when the thickness of the black matrix layer 220 is less than 0.9um, the resistance thereof changes faster, and the reduction of the thickness of the black matrix layer 220 can effectively increase the resistance of the black matrix layer 220, so that the thickness of the black matrix layer 220 in the present application does not exceed 0.9um, so that the resistance thereof is larger, and the charge transfer can be effectively blocked, thereby reducing the electrostatic risk. In summary, when the thickness of the black matrix layer 220 in the present application is between 0.7um and 0.9um, the shading effect of the black matrix layer 220 can be ensured, and a better anti-static effect can be achieved.
In addition, the first and second grooves 230 and 240 are filled with blue color resists. The resistance of the blue color resistor is large, so that the antistatic effect can be achieved; and the blue color resistor can also play a role in shading light, so that the blue color resistor is matched with the blind groove-shaped groove to further enhance the shading effect at the groove. When the first groove 230 and the second groove 240 correspond to the sealant, the thickness of the blue color resist is greater than the depths of the first groove 230 and the second groove 240, so that a part of the blue color resist can sink into the sealant, and the absorption force between the color film substrate 200 and the sealant is increased.
Fig. 4 is a schematic plan view of a color filter substrate 200 provided with a third groove 250. As another embodiment of the present application, a schematic view of another color filter substrate 200 is further disclosed, where the color filter substrate 200 includes a third groove 250, and the third groove 250 is disposed in the black matrix layer 220 and located on an observation side of the color filter substrate 200; the width of the third groove 250 is 1-10 um. Because the width of the third groove 250 is small and light leakage is not easy, the third groove 250 can be continuously added on the observation side of the color film substrate 200, so that the effects of further blocking charge transfer and increasing static electricity prevention are achieved; the third grooves 250 may be provided on only one of the viewing sides, or the third grooves 250 may be provided on all the other viewing sides.
In addition, the third groove 250 is located between the first groove 230 and the edge of the black matrix layer 220, and the length of the third groove 250 is greater than the length of the first groove 230; the first groove 230 and the third groove 250 are through grooves, and blue color resists are filled in the first groove 230 and the third groove 250; the through groove is a first groove 230 and a third groove 250 penetrating through the black matrix layer 220 in the thickness direction of the black matrix layer 220. The third groove 250 is located between the first groove 230 and the edge of the black matrix layer 220, so that the length of the third groove 250 is not limited in the black matrix, and thus increasing the length of the third groove 250 can increase the resistance of the whole black matrix and increase the blocking area for charges.
Fig. 5 is a schematic plan view of a color filter substrate 200 provided with a fourth groove 260. As another embodiment of the present application, a schematic view of another color filter substrate 200 is further disclosed, where the color filter substrate 200 includes a fourth groove 260, and the fourth groove 260 is disposed in the black matrix layer 220 and located on a non-observation side of the color filter substrate 200; the width of the fourth groove 260 is 15-40 um. Since the observation side is not easy to attract the attention of the user, the fourth groove 260 with a larger width is additionally arranged on the non-observation side, so that the black matrix layer 220 close to the display area 211 is further prevented from being electrified; the fourth groove 260 may be disposed on only one of the non-viewing sides, or the fourth groove 260 may be disposed on all other non-viewing sides, wherein the fourth groove 260 is filled with blue color resists, thereby further preventing light leakage.
In addition, the fourth groove 260 is located between the second groove 240 and the edge of the black matrix layer 220, and the length of the fourth groove 260 is greater than the length of the second groove 240; the second groove 240 and the fourth groove 260 are blind grooves, and blue color resists are filled in the second groove 240 and the fourth groove 260; the blind groove is formed by the second groove 240 and the fourth groove 260 not penetrating through the black matrix layer 220 in the thickness direction of the black matrix layer 220. Also, the fourth groove 260 is located between the second groove 240 and the edge of the black matrix layer 220, so that the length of the fourth groove 260 is not limited in the black matrix layer 220, and thus increasing the length of the fourth groove 260 may increase the resistance of the entire black matrix layer 220, and increase the blocking area for charges.
