Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present invention, and fig. 2 is a schematic structural diagram of a cross section of the display panel shown in fig. 1 taken along AA', referring to fig. 1 and fig. 2, the display panel 10 includes a display area and a non-display area (fig. 1 only shows the display area), and the display area includes a display area boundary; the display area is provided with a plurality of pixel units which are arranged in an array along a first direction and a second direction, and the pixel units comprise first pixel units 11 close to the boundary of the display area; the first pixel unit 11 includes at least three sub-pixels sequentially arranged along a first direction, wherein the first direction and the second direction are perpendicular to each other and are parallel to a plane where the display panel is located; the display panel further comprises an array substrate 100 and a color film substrate 200 arranged opposite to the array substrate 100, wherein the color film substrate 200 comprises a substrate 201; the first pixel unit 11 includes a color resistance layer 203, a first light adjusting layer 204 and a planarization layer 205 which are stacked on one side of a substrate 201; the first pixel unit 11 further includes a light shielding layer 202 disposed on the same layer as the color resist layer 203, the light shielding layer 202 includes a plurality of light shielding subsections 2021, the color resist layer 203 includes a plurality of color resists of different colors, and the light shielding subsections 2021 are located between two adjacent color resists; the refractive index of the first light adjustment layer 204 is greater than the refractive index of the planarization layer 205; the first light adjustment layer 204 has a plurality of protruding structures on a side thereof facing away from the substrate 201, and a vertical projection of the protruding structures on the substrate 201 covers a vertical projection of the shading portion 2021 on the substrate 201.

First, it should be noted that the embodiment of the present invention does not limit the type of the display panel. For example, the display panel may be a liquid crystal display panel or an organic light emitting display panel. Exemplarily, fig. 2 illustrates a schematic cross-sectional structure of a display panel along AA' by taking the liquid crystal display panel as an example, referring to fig. 2, when the display panel is a liquid crystal display panel, the display panel includes a liquid crystal layer 300 disposed between an array substrate 100 and a color filter substrate, and hereinafter, the technical solution of the embodiment of the present invention is first described by taking the liquid crystal display panel as an example.

For example, fig. 1 illustrates the display area as a circle. In fig. 1, each of the rectangular dashed boxes corresponds to a pixel unit, and as shown in fig. 1, the display area is provided with a plurality of pixel units arranged in an array along a first direction and a second direction, and for convenience of description, the pixel unit near the boundary of the display area is referred to as a first pixel unit 11, and the pixel unit on the side of the first pixel unit 11 far from the boundary of the display area is referred to as a second pixel unit 12. As can be seen from fig. 1, since the first pixel unit 11 does not match with the display area boundary of the display panel, a situation of edge jaggy may occur during display.

It should be noted that the display panel may be a display panel with any shape as long as the shape of the display area boundary does not match the shape of the pixel unit, and exemplarily, the display area boundary is a non-rectangular boundary, which is not limited by the embodiment of the present invention. For example, the conventional display screens such as the "bang screen" and the "water drop screen" have non-rectangular boundaries, and when the display screens are displayed, the display screens have edge saw-tooth feeling, and meanwhile, the first direction and the second direction are perpendicular to each other and are parallel to the plane of the display panel.

For example, fig. 1 shows a case where the first pixel unit 11 (or any one of the pixel units) includes 3 sub-pixels, for example, the 3 sub-pixels may be a red sub-pixel, a green sub-pixel, and a blue sub-pixel arranged in sequence along the first direction. The embodiment of the utility model provides a do not restrict the quantity of sub-pixel in the pixel unit, the pixel unit include at least three sub-pixel can, the skilled in the art personnel can be according to the demand by oneself and restrict. The first pixel unit 11 includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel.

The display device realizes the display of the picture by controlling the light emitting color and the light emitting brightness of each sub-pixel. Specifically, the light emission color of the sub-pixels is mainly realized by the filtering action of the color resistance layer 203 in the color film substrate 200, and the color resistance layer 203 includes a plurality of color resistances with different colors, the number of the color resistances corresponds to the number of the sub-pixels in the pixel unit, and the sub-pixels can emit light with a target color after being filtered by the color resistances. For example, as shown in fig. 1 and fig. 2, along the AA' direction, the color resist layer 203 in the color filter substrate 200 sequentially includes a red color resist 2031, a green color resist 2032, and a blue color resist 2033, and the 3 color resists of different colors are used to filter the white light incident into the color filter substrate 200, so that different colors of light can be emitted from each sub-pixel, and the display of the picture can be realized. The light-shielding layer 202 in the color filter substrate 200 mainly plays a role of light shielding and is used for defining the positions of the sub-pixels. The light-emitting brightness of the sub-pixels is mainly controlled by the driving circuit in the array substrate 100, and the embodiment of the present invention does not limit the structure of the array substrate 100, and the skilled person can set the brightness by himself.

For a liquid crystal display panel, a planarization layer 205 is usually further disposed on a side of the color filter substrate 200 close to the liquid crystal layer 300 to facilitate the disposition of the liquid crystal alignment layer. In order to improve marginal sawtooth sense when showing, the embodiment of the utility model provides an add first light adjustment layer 204 between color resistance layer 203 and planarization layer 205, the refracting index that makes first light adjustment layer 204 is greater than planarization layer 205, so, can make the light of inciding in various membrane base plate 200 take place to refract in the interface department of first light adjustment layer 204 and planarization layer 205, make partly originally sheltered from the emergent light of color resistance by adjacent shading subsection 2021, with the luminous luminance that reduces first pixel unit 11, marginal sawtooth sense when improving the demonstration. Exemplarily, referring to fig. 2, fig. 2 shows a schematic diagram of an optical path of light emitted from the red color resistor 2031 of the first pixel unit 11, wherein a dotted line with an arrow indicates an original emitting direction of the light, and a solid line with an arrow indicates an optical path after refraction occurs at an interface of the first light adjusting layer 204 and the planarization layer 205, and as can be seen from fig. 2, due to refraction, a part of light emitted from the red color resistor 2031 is blocked by the light blocking sub-portion 2021, so that the light emitting brightness of the red color resistor 2031 is reduced. Similarly, the luminance of the green color resistor 2032 and the luminance of the blue color resistor 2033 in the first sub-pixel are also reduced, so that the luminance of the first pixel unit 11 is reduced, and the edge jaggy feeling during display is improved.

In order to ensure that only the luminance of the first pixel unit 11 is reduced, the luminance of the pixel unit (the second pixel unit 12) far away from the boundary of the display area is not affected, the embodiment of the present invention provides the following design for the structure of the first light adjustment layer 204. Referring to fig. 2, the display panel may be divided into two parts along a dotted line in fig. 2, the left side of the dotted line corresponding to the structure of the second pixel unit 12, and the right side of the dotted line corresponding to the structure of the first pixel unit 11. As shown in fig. 2, although the first light adjustment layer 204 is disposed between the color resist layer 203 and the planarization layer 205 in each of the first pixel unit 11 and the second pixel unit 12, the structure of the first light adjustment layer 204 in the first pixel unit 11 is different from that of the first light adjustment layer 204 in the second pixel unit 12. Specifically, the first light adjustment layer 204 in the first pixel unit 11 has a protrusion structure facing the planarization layer 205, and a vertical projection of the protrusion structure on the substrate 201 covers a vertical projection of the light shielding subsection 2021 of the first pixel unit 11 on the substrate 201, and a plane of the first light adjustment layer 204 in the second pixel unit 12 is parallel to a plane of the planarization layer 205, that is, the protrusion structure is only disposed corresponding to the light shielding subsection 2021 in the first pixel unit 11.

It should be noted that there are light-shielding sections (such as the light-shielding sections located at the positions of the dotted lines in fig. 2) between the first pixel unit and the adjacent second pixel unit, and the protrusion structures corresponding to the light-shielding sections may be arranged in two ways. First, as shown in fig. 2, the vertical projection of the protrusion structure on the substrate may cover the whole light-shielding subsection, and second, the protrusion structure may also cover only the part of the light-shielding subsection located in the first pixel unit located on the right side of the dotted line, which is not limited by the embodiment of the present invention.

The working principle of the embodiment of the present invention will be described in further detail with reference to fig. 2. Referring to fig. 2, the interface between the protruding structure of the first light adjusting layer 204 and the planarization layer 205 includes a "parallel interface" parallel to the plane of the substrate 201 and an "intersecting interface" intersecting the plane of the substrate 201, with reference to the plane of the substrate 201. For the light incident on the "parallel interface", since the directions of the light are bilaterally symmetric with respect to the normal line, the refraction of the "parallel interface" for the incident light is the same, which causes a part of the light originally shielded by the light shielding layer 202 to be emitted from the color resistor, and also causes a part of the light originally emitted from the color resistor to be shielded by the light shielding layer 202, since the emission and shielding effects of the two parts of light cancel each other out, the "parallel interface" cannot play a role in reducing the light emitted from the color resistor, in other words, the "parallel interface" does not affect the light emitting brightness of the pixel unit. As such, even if the first light adjustment layer 204 is also provided in the second pixel unit 12, the light emission luminance of the second pixel unit 12 is not affected. For the light rays incident to the "intersecting interface", part of the light rays originally emitted from the color resistor are refracted and then shielded by the light shielding sub-portion 2021, so that the effect of reducing the light emitting brightness of the first pixel unit 11 is achieved, and the edge jaggy feeling during display is improved. Generally speaking, the embodiment of the present invention provides a light beam emitted from the color resistor originally is shielded by the shading sub-portion 2021 by the refraction of the "intersecting interface" of the first light adjusting layer 204 and the planarization layer 205 on the light, so as to reduce the brightness of the first pixel unit 11 and improve the edge saw tooth feeling during displaying.

Specifically, the extension length of the protrusion structure of the first light adjusting layer 204 in the first direction may be properly greater than the extension length of the light shielding section 2021 in the first direction, so that more light originally emitted from the color resistor can be refracted at the "intersecting interface" of the first light adjusting layer and the planarization layer 205, and then be shielded by the light shielding section 2021. Since the first light adjusting layer 204 mainly functions to change the light path, the thickness thereof can be thinner, thereby avoiding increasing the thickness of the display panel. The refractive index of the first light adjusting layer 204 is larger than the planarization layer 205, and the embodiment of the present invention does not limit the size and the refractive index thereof, and those skilled in the art can adaptively adjust the above parameters according to the actual situation to achieve the purpose of reducing the luminance of the first pixel unit 11. For example, the thickness of the first light adjustment layer 204 at the corresponding position of the protrusion structure may be 0.2 μm, the refractive index of the first light adjustment layer 204 may be 1.91, and the refractive index of the planarization layer 205 may be 1.4.

On the basis of the above embodiments, referring to fig. 3, fig. 3 is another schematic cross-sectional structure of the display panel shown in fig. 1 taken along AA', and fig. 3 still takes the liquid crystal display panel as an example to further optimize the structure of the display panel. As shown in fig. 3, optionally, the protruding structure includes a first surface close to one side of the substrate 201 and a second surface far from one side of the substrate 201, a perpendicular projection of the first surface on the substrate 201 covers a perpendicular projection of the second surface on the substrate 201, and an extension length of the first surface is greater than an extension length of the second surface along the first direction.

With such an arrangement, the area of the "intersecting interface" can be increased, and more light emitted from the color resistor is refracted at the interface, and is further shielded by the light shielding sub-portion 2021, thereby improving the edge jaggy feeling. In addition, as shown in fig. 3, compared to the protrusion structure shown in fig. 2, the normal of the "intersecting interface" can be inclined toward the light-shielding section 2021, and under the condition that the refractive indexes of the first light adjustment layer 204 and the planarization layer 205 are not changed, the refracted light will be more deviated to the plane of the substrate 201 in this scheme, so as to avoid the refracted light from exiting from the adjacent color resists beyond the coverage of the light-shielding section 2021. It should be noted that, the inclination angle of the "intersecting interface" in the embodiment of the present invention is not limited, and those skilled in the art can set the inclination angle according to actual situations.

With continued reference to fig. 3, optionally, the second face has the same extension as the extension of the shading portion 2021 in the first direction.

The extension of the relief structure in the first direction does not exceed the extension of the shading portion 2021 in the first direction too much, otherwise, there may be a case that the light is still emitted from the color resist even though it is refracted. To avoid this, and to reduce the difficulty of designing the size and refractive index of the first light adjustment layer 204, the light refracted at the "intersecting interface" is irradiated to the light shielding section 2021, and preferably, the extension length of the second surface in the first direction is the same as the extension length of the light shielding section 2021.

Fig. 4 is a schematic cross-sectional view of the display panel shown in fig. 1 taken along line AA', and referring to fig. 4, optionally, the first pixel unit 11 further includes a second light adjusting layer 206 disposed between the first light adjusting layer 204 and the color-resisting layer 203; the vertical projection of the second light adjusting layer 206 on the substrate 201 covers the vertical projection of the light shielding section 2021 on the substrate 201, and the refractive index of the second light adjusting layer 206 is greater than the refractive index of the first light adjusting layer 204.

The viewing angle of light incident on the color filter substrate 200 can be controlled, and the viewing angle is usually smaller, for example, the viewing angle can be 60 ° or even smaller, so that crosstalk between different sub-pixels of a light source can be avoided, and actual light brightness of the sub-pixels is difficult to control. Fig. 2 and 3 are schematic diagrams illustrating the light path of the incident light with a small viewing angle. However, when the viewing angle of light incident on the color filter substrate 200 is large, there may be a case where light (shown by a dotted line 1 in fig. 4) originally capable of being blocked by the light blocking sub-portion 2021 is emitted from the color resists of the adjacent second pixel units 12 (shown by a dotted line 2 in fig. 4) due to the refraction effect of the first light adjustment layer 204, and the light emission luminance of the second pixel units 12 is increased. In order to avoid this situation, the embodiment of the present invention adds the second light adjustment layer 206 with a larger refractive index between the first light adjustment layer 204 and the color resistance layer 203 in the first pixel unit 11, so that the vertical projection of the second light adjustment layer 206 on the substrate 201 covers the vertical projection of the light shielding sub-portion 2021 on the substrate 201, and thus, part of the light emitted from the first light adjustment layer will be refracted again at the interface between the second light adjustment layer and the first light adjustment layer, so that the light originally shielded by the light shielding sub-portion 2021 can still be shielded (as shown by the solid line in fig. 4), and the light is prevented from being emitted from the color resistance of the adjacent second pixel unit 12 due to the existence of the first light adjustment layer 204. Preferably, the refractive index of the second light adjusting layer 206 is much greater than the refractive index of the first light adjusting layer 204.

It can be understood that, because the vertical projection of the second light adjustment layer 206 on the substrate 201 covers the vertical projection of the light shielding section 2021 on the substrate 201, the light originally shielded by the light shielding section 2021 due to the refraction of the first light adjustment layer 204 can still be shielded by the light shielding section 2021, the second light adjustment layer 206 does not affect the effect that the first light adjustment layer 204 can achieve, and can also achieve the same effect when the angle of view of the incident light is large, and at the same time, can avoid affecting the luminance of the second pixel unit 12.

With continued reference to fig. 4, further optionally, the second light adjusting layer 206 includes a third surface near one side of the substrate 201 and a fourth surface far from one side of the substrate 201; the perpendicular projection of the third surface on the substrate 201 covers the perpendicular projection of the fourth surface on the substrate 201, and the extension length of the third surface is greater than that of the fourth surface along the first direction. Further alternatively, the fourth face may have the same extension as the extension of the light shielding section 2021 in the first direction. The design concept is the same as that of the protrusion structure of the first light adjustment layer 204, and is not described herein again.

Optionally, the first light adjustment layer 204 and the second light adjustment layer 206 are made of resin materials.

The variety of resin material is various, and different resin material's refracting index is different, and the skilled person in the art can select by oneself, and the utility model discloses the embodiment does not limit to this.

Referring to fig. 1, optionally, the display panel 10 further includes a plurality of supporting pillars 301 disposed between the array substrate 100 and the color filter substrate 200, and a vertical projection of the supporting pillars 301 on the substrate overlaps with a vertical projection of at least a portion of the light shielding sub-portion 2021 on the substrate 201.

Specifically, the plurality of support pillars 301 are arranged between the array substrate 100 and the color film substrate 200, so that the color film substrate 200 can be supported, and the performance of the display panel is improved. In addition, the vertical projection of the supporting column 301 on the substrate is overlapped with the vertical projection of at least part of the shading sub-portion 2021 on the substrate 201, that is, the supporting column 301 and the shading sub-portion 2021 are correspondingly disposed, so that on one hand, the supporting column 301 can be prevented from affecting the propagation of light, and on the other hand, the metal structure (such as an electrode and a wire) in the array substrate 100 can be shielded, thereby preventing the metal structure from reflecting light and affecting the display effect.

It will be appreciated that the second pixel cell 12 also includes a light blocking section between adjacent color resists, and the support posts 301 may be positioned to correspond to the light blocking section in the second pixel cell. Furthermore, the embodiment of the present invention does not limit the number of the supporting pillars 301, as long as sufficient supporting force can be provided.

In summary, the above embodiments take the liquid crystal display panel as an example to introduce the technical solution of the present invention. Next, taking the organic light emitting display panel as an example, the scheme of the present invention is simply introduced, and the same structure is not repeated herein. Fig. 5 is a schematic cross-sectional view of the display panel shown in fig. 1, taken along AA', and referring to fig. 5, the display panel is optionally an organic light emitting display panel; the array substrate 100 comprises a driving circuit 101 and an anode 102 located on one side of the driving circuit 101 close to the color film substrate 200; the display panel includes an organic light emitting material layer 401 and a cathode 402 disposed between the array substrate 100 and the color filter substrate 200.

The organic light emitting display panel can self-emit light without a backlight source. For the organic light emitting display panel, the organic light emitting diodes correspond to the sub-pixels one by one, and the driving circuit 101 on the array substrate 100 controls the light emitting brightness of the organic light emitting diodes to realize the display of the picture. More specifically, when the light emitted from the light emitting diode is white light, the color filter substrate 200 may be configured to perform a filtering function, so that different sub-pixels emit light of different colors.

Referring to fig. 5, the driving circuit 101 includes Thin Film Transistors (TFTs), and the driving circuit 101 may be an active driving circuit of "1T" (one TFT) type or an active driving circuit of "2T 1C" (two TFTs and one capacitor) type, for example. In addition, the driving circuit 101 may also be a passive driving circuit, which is not limited by the embodiment of the present invention. The light emitting diode is mainly composed of an anode 102, a cathode 402, and an organic light emitting material layer 401 between the anode 102 and the cathode 402, wherein the anode 102 is electrically connected to the drain of the thin film transistor, and the cathode 402 is grounded. Under the control of the driving circuit, light emitted from each light emitting diode is irradiated onto the color filter substrate 200, and under the action of the first light adjustment layer 204 (and the second light adjustment layer 206), part of light originally emitted from the color resistor of the first pixel unit 11 is blocked by the light blocking sub-portion 2021, so that the light emitting brightness of the first pixel unit 11 is reduced, and the jaggy feeling during display is improved.

Based on the same utility model discloses think, the embodiment of the utility model provides a still provides a display device, and fig. 6 is the utility model provides a display device's schematic structure diagram, this display device include the display panel that any above-mentioned embodiment provided, therefore possess the same beneficial effect with above-mentioned display panel, the same part can refer to the description of above-mentioned display panel embodiment, no longer gives details here. As shown in fig. 6, the display area of the display device has a non-rectangular boundary in a circular dashed-line frame region, and since the light emission luminance of the first pixel cell 11 of the display area near the non-rectangular boundary (i.e., the display area boundary) is reduced, the edge jaggy feeling of the display device when displaying a screen is weak.
