The present application will be described in detail below with reference to the drawings and the optional embodiments, and it should be noted that, without conflict, new embodiments may be formed by any combination of the embodiments or technical features described below.
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, and the display panel 100 includes an array substrate 300 and a color film substrate 200 arranged in a pair of boxes. As shown in fig. 2, the color film substrate 200 is a schematic diagram of the above color film substrate 200, where the color film 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 are 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 are respectively located on the non-viewing side of the color film substrate 200; 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 larger than the width of the first grooves 230.
Along with the improvement of the appearance requirement of display screen products, the main stream of the market mainly adopts EBL (Entry Borderless) technology to produce products, namely the borderless design of the products, but at the same time, the problem of light leakage at the edge is also brought. The existing design is to increase the size of the glass of the color film substrate 210 so that the black matrix layer 220 is flush with the edge of the color film substrate 210. The design utilizes the black matrix layer 220 to achieve an edge light blocking effect for better user experience. However, the design may make the black matrix layer 220 excessively exposed (close to the glass edge), so that the black matrix on the color film substrate 200 corresponds to the peripheral metal signal lines on the array substrate 300, when the display panel 100 works, the black matrix layer 220 generates induced voltage, generates Static electricity, and affects the deflection of the liquid crystal, so that the risk of ESD (Electro-Static discharge) is greatly increased, and the product performance is reduced. Currently, static electricity is mostly prevented from being transferred into the display area 211 by breaking the black matrix layer in the non-display area 212; however, this may cause a risk of light leakage, affecting 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 views the display screen, the eyes concentrate on the observation side due to the observation angle, and the eyes are easy to observe when light leakage occurs on the observation side; therefore, the width of the second groove 240 on the non-observation side is larger than that of the first groove 230 on the observation side, the first groove 230 on the observation side is smaller in width and is not easy to observe, and light leakage caused by sensitivity of human eyes on the observation side to light is avoided; the second grooves 240 on the non-viewing side have a larger width but are not easily noticeable to the user, and the pitch of the black matrix on both sides of the second grooves 240 is increased; therefore, the anti-static effect is further increased while the light leakage is prevented.
The viewing side is one or more sides of the display panel where the viewing angle is not fixed and the variation range is large, the variation range of the viewing angle of the viewing side is relatively large (e.g., 0 to 180 °), and the viewing angle of the non-viewing side is relatively fixed (90 ° or a small variation range). The common observation sides of the televisions and computers which are commonly used at present are left and right sides; but in some use environments the upper and lower sides of the display screen are the viewing sides.
Specifically, the width of the first groove 230 is 1-10um, and the width of the second groove 240 is 15-40um. When the width of the groove is smaller than 1um, the process deviation is larger, and the grooving cannot be accurately realized; the 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 if the width of the grooves is widened continuously, the light leakage can be caused as the viewing angle of the observation side is increased; because the width of the liquid crystal box is 3-6um at present, the width of the metal wiring in the corresponding array substrate is 40um, and light refraction caused by different materials such as an insulating layer on the metal wiring, the liquid crystal box and the like is also considered, based on various considerations, the width of the observation side grooved position is set to be smaller than 10um, and if the width of the observation side grooved position is larger than 10um, the light leakage risk exists in the large visual angle direction. On the non-observation side, due to the observation angle, light leakage of the region is not easy to be perceived by human eyes, so that the width of the digging groove can be increased; however, when the width of the metal wiring in the array substrate exceeds the corresponding position, and the width of the dug groove is increased, the risk of light leakage is increased, so that the width of the dug groove of the non-observation side BM is limited to 15-40um.
Wherein the first groove 230 is a through groove, and the second groove 240 is a blind groove; when the first groove 230 penetrates 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 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. Since the width of the first groove 230 is smaller and the light transmission amount is smaller, the first groove 230 is set as a through groove to block charge transfer, so that static electricity can be effectively prevented; since the second groove 240 has a large width, although the antistatic effect can be enhanced, the second groove 240 is formed as a blind groove because the large width is prone to light leakage, and thus the problem of light leakage caused by the blind groove can be prevented. The thickness of the black matrix under the second grooves 240 is 0.7-0.9um, as shown in fig. 3, which is a schematic diagram showing the variation of the resistance and OD value with the thickness of the black matrix layer 220, and it can be seen from the figure that the resistance is gradually reduced and the OD value is gradually increased when the thickness of the black matrix layer 220 is increased.
As shown in the OD curve in the figure, when the OD value is greater than 4, the black matrix layer 220 has a good shading 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 film substrate 200 does not leak light; as can be seen from the resistance curve in the figure, when the thickness of the black matrix layer 220 exceeds 0.9um, the resistance reaches the near saturation degree, and when the thickness of the black matrix layer 220 is less than 0.9um, the trend of the resistance change is faster, and reducing 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 does not exceed 0.9um in the application, the resistance is larger, the charge transfer can be effectively blocked, and the static risk is reduced. In summary, when the thickness of the black matrix layer 220 is between 0.7um and 0.9um, the black matrix layer 220 can not only ensure the shading effect, but also achieve better antistatic effect.
In addition, the first groove 230 and the second groove 240 are filled with blue color resist. The blue resistor has larger resistance, so that an antistatic effect can be achieved; and the blue color resistor can also play a role in shading, so that the blue color resistor is matched with the blind groove-shaped groove to further strengthen the shading effect at the groove. When the first groove 230 and the second groove 240 correspond to the frame glue, the thickness of the blue color resistor is greater than the depth of the first groove 230 and the second groove 240, so that a part of the blue color resistor can sink into the frame glue to increase the adsorption force between the color film substrate 200 and the frame glue.
Fig. 4 is a schematic plan view of a color film substrate 200 with a third groove 250. As another embodiment of the present application, a schematic diagram of another color film substrate 200 is also disclosed, where the color film substrate 200 includes a third groove 250, and the third groove 250 is disposed in the black matrix layer 220 and is located on the viewing side of the color film substrate 200; the third recess 250 has a width of 1-10um. Because the third groove 250 has smaller width and is not easy to leak light, the third groove 250 can be further added on the observation side of the color film substrate 200, thereby further blocking charge transfer and increasing antistatic effect; the third grooves 250 may be provided on only one of the viewing sides, or the third grooves 250 may be provided on 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 third groove 250 has a length greater than that of the first groove 230; the first groove 230 and the third groove 250 are through grooves, and blue resistors are filled in the first groove 230 and the third groove 250; the through grooves are the first grooves 230 and the third grooves 250 penetrating 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 increases the resistance of the entire black matrix and increases the blocking area for charges.
Fig. 5 is a schematic plan view of a color film substrate 200 with a fourth groove 260. As another embodiment of the present application, a schematic diagram of another color film substrate 200 is also disclosed, where the color film substrate 200 includes a fourth groove 260, and the fourth groove 260 is disposed in the black matrix layer 220 and is located on a non-viewing side of the color film substrate 200; the width of the fourth groove 260 is 15-40um. Since the viewing side is not easy to draw the attention of the user, the fourth groove 260 with larger width is added on the non-viewing side to further prevent the black matrix layer 220 near the display area 211 from being charged; the fourth grooves 260 may be disposed on only one of the non-viewing sides, or may be disposed on all other non-viewing sides, wherein the fourth grooves 260 are filled with blue color resists, so as to further prevent 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 resistors are filled in the second groove 240 and the fourth groove 260; the blind grooves are the second grooves 240 and the fourth grooves 260 that do not penetrate 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 such 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 against charges.
Fig. 6 is a schematic plan view of a color film substrate 200 with a third groove 250 and a fourth groove 260. As another embodiment of the present application, a schematic diagram of another color film substrate 200 is also disclosed, where the color film substrate 200 includes two third grooves 250 and two fourth grooves 260, the two third grooves 250 are located on the observation side of the color film substrate 200, the two fourth grooves 260 are located on the non-observation side of the color film substrate 200, and the two third grooves 250 and the two fourth grooves 260 are connected end to form a ring shape; wherein two third grooves 250 are respectively located between two first grooves 230 and edges of the black matrix layer 220, and a length of the third grooves 250 is greater than a length of the first grooves 230; the two fourth grooves 260 are respectively located between the two second grooves 240 and the edges of the black matrix layer 220, and the length of the fourth grooves 260 is greater than that of the second grooves 240, so that the annular grooves formed by the third grooves 250 and the fourth grooves 260 are arranged at the periphery of the annular grooves formed by the first grooves 230 and the second grooves 240, the grooved areas of the annular grooves formed by the newly added third grooves 250 and the third grooves 250 are larger, and the black matrix layer 220 is further divided by the two annular grooves, so that the antistatic effect is further improved.
In addition, the first groove 230 and the third groove 250 penetrate the first black matrix layer 220 in the first direction, the second groove 240 and the fourth groove 260 do not penetrate the first black matrix layer 220 in the first direction, and blue resists are filled in the first groove 230, the second groove 240, the third groove 250 and the fourth groove 260; the first direction is a thickness direction of the black matrix layer 220, the width of the third groove 250 is 1-10um, and the width of the fourth groove 260 is 15-40um.
It should be noted that, in the present application, the positions of the first groove 230, the second groove 240, the third groove 250 and the fourth groove 260 correspond to the metal traces in the array substrate 300, so as to further increase the light shielding effect.
