Description
Technical Field
The invention relates to the technical field of display, in particular to a pixel structure, a preparation method thereof and a display panel.
Background
In the liquid crystal display device, the light source provided for the liquid crystal display device to display has a certain directivity when being output after being refracted and reflected, and when the light source is viewed beyond the range, the color distortion phenomenon can be generated. The size of the viewing angle of the display device determines the size of the user's viewing range and the optimal viewing angle. At present, the standard of the viewing angle test in the display industry is that the total white brightness (L255 brightness)/total black brightness (L0 brightness) > 10, namely, the ratio of the L255 brightness to the L0 brightness is greater than 10. The ratio of the L255 brightness to the L0 brightness is abbreviated as CR (contrast ratio), and the angle range with CR > 10 is the visible angle range. When CR is decreased to 10, the corresponding angle is the maximum viewing angle of the liquid crystal display device. Generally, a user has a visual angle of 120 ° as a criterion for selecting a display device.
With the continuous progress of display technology and the continuous improvement of display quality requirements of clients, the requirements of the visual angle of a display product are also continuously improved, and the requirements of the contrast ratio in the visual angle are also continuously improved, especially for vehicle-mounted display, public display products and the like. Fig. 1 is a diagram of the latest vehicle-mounted german standard. As can be seen from FIG. 1, the latest on-board German standards have specified that CR >650 is required at specific viewing angles (zone A).
From the specification shown in fig. 1, it is apparent that the viewing angle requirements of the onboard german5.0spec are significantly different in the up-down direction. German5.0Spec requires a product with a much higher up viewing angle than down viewing angle, requiring a contrast ratio of 650 for a 10 deg. down viewing angle and 650 for a 20 deg. up viewing angle. This is because the vehicle customer, when viewing the screen, mostly views the screen from an upper viewing angle due to his/her own position. However, the existing products In the common Plane Switching (IPS), Advanced Super Dimension Switching (ADS) and HADS modes are difficult to meet the standard, resulting In poor user experience. In order to meet the german5.0 standard, a new display panel is required to increase the contrast of the display device at a specific viewing angle, so as to meet the higher specification requirements of customers.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Fig. 2 is a schematic top view of a liquid crystal display panel, and fig. 3 is a schematic sectional view taken along line a-a in fig. 2. The display panel includes red (R), green (G), and blue (B) pixels. Taking green pixels as an example, fig. 2 shows a pixel structure corresponding to G pixels. It is easily understood that the structure of R, G, B three pixels is the same.
As shown in fig. 3, the display panel includes a first substrate 10, a second substrate 20, and a liquid crystal layer 30 between the first substrate 10 and the second substrate 20, which are oppositely disposed. The second substrate 20 may be an array substrate, a color film 11 corresponding to a pixel is disposed on the first substrate 10 away from the first substrate 10, and a black matrix 12 is disposed between adjacent color films 11. The surface of the first substrate 10 facing away from the second substrate 10 is a light emitting surface 13 of the display panel. The color film 11 is provided with a first structural layer 41, and a second structural layer 42 is provided on a side of the second substrate 20 facing the liquid crystal layer 30. The first structural layer 41 and the second structural layer 42 are both flat structures, and the surface of the liquid crystal layer 30 facing the first substrate 10 is parallel to the first substrate 10 (i.e. parallel to the light emitting surface 13), and d1 is d2, as shown in fig. 3.
Fig. 4 is a schematic top-bottom view of the region a of the display panel shown in fig. 3. As shown in fig. 4, the upper viewing angle α of the region a is 20 °, and the lower viewing angle β is 10 °. The contrast ratio of the upper viewing angle and the lower viewing angle of the a region of the display panel shown in fig. 4 was tested to obtain the structure shown in table 1.
Table 1 results of the area a contrast ratio of the display panel shown in fig. 4
| Zone A | UL (left upper view angle) | UR (Right upper view angle) | DL (left lower view angle) | DR (Right lower view angle) |
| Contrast ratio | 632 | 600 | 821 | 875 |
As can be seen from fig. 1 and table 1, the angles of the side viewing angles UL and UR are significantly greater than those of the side viewing angles DL and DR, so the contrast test results of UL and UR are significantly less than those of DL and DR, the upper and lower viewing angles of the display panel are asymmetric, the difference between the contrast of the upper viewing angle and the contrast of the lower viewing angle is large, the symmetry is poor, the contrast of the upper viewing angle in the area a does not reach 650, and cannot meet the product requirements of specific specifications (for example, German5.0 specification CR >650), and the contrast of the lower viewing angle in the area a is greater than 650, and can meet the product requirements of specific specifications, and the range is large, the performance is excessive, and the failure risk of the upper viewing angle (i.e., the NG risk of the upper viewing angle is high).
The technical contents of the present invention will be described in detail by specific embodiments.
The first embodiment:
fig. 5 is a schematic view of a pixel structure according to a first embodiment of the invention. As shown in fig. 5, the pixel structure includes a first substrate 10, a second substrate 20, and a liquid crystal layer 30 between the first substrate 10 and the second substrate 20, which are oppositely disposed. The surface of the first substrate 10 facing away from the second substrate is a light exit surface 13, and the surface of the liquid crystal layer 30 facing the first substrate 10 is an inclined surface relative to the light exit surface 13. It is easily understood that the first substrate 10 is a flat substrate, and thus, in the embodiment, "a surface inclined with respect to the light exit surface" has the same meaning as "a surface inclined with respect to the first substrate".
In the pixel structure provided by the embodiment of the invention, the surface of the liquid crystal layer 30 facing the first substrate 10 is an inclined surface relative to the light emitting surface 13, that is, the light emitting surface of the liquid crystal layer 30 is not parallel to the light emitting surface 13 of the pixel structure, but is inclined relative to the light emitting surface 13 of the pixel structure. Therefore, as shown in fig. 5, the liquid crystal layer 30 is placed obliquely in the lateral direction, and the right side of the liquid crystal layer 30 is higher than the left side, which is equivalent to placing the display screen obliquely in a state that the right side is higher than the left side, so that the center line 31 of the display screen is shifted from the vertical direction to the left side, and the contrast of the viewing angle corresponding to the shift direction of the center line 31 can be improved. When the surface of the liquid crystal layer 30 facing the first substrate is inclined with respect to the light emitting surface 13, the center line of the display screen is shifted toward a specific viewing angle, so that the contrast of the display panel at the specific viewing angle can be increased, and the higher specification requirements of the customers can be satisfied.
In the present embodiment, the second substrate 20 may be an array substrate. A corresponding color film 11 may be disposed on the first substrate 10, and a black matrix 12 is disposed around the color film 11.
As shown in fig. 5, the pixel structure further includes a first structure layer 41. The first structural layer 41 is disposed on the first substrate 10 on the side facing the liquid crystal layer 30, and in this embodiment, the first structural layer 41 is disposed on the color film 11. The surface of the first structure layer 41 facing the liquid crystal layer 30 is an inclined surface with respect to the light exit surface 13, and the liquid crystal layer 30 is disposed between the first structure layer 41 and the second substrate 20. Thus, the surface of the liquid crystal layer 30 facing the first substrate 10 is inclined with respect to the light emitting surface 13.
In the present embodiment, by setting the surface of the first structure layer 41 on the side facing the liquid crystal layer 30 to be an inclined surface with respect to the light exit surface 13, it is realized that the surface of the liquid crystal layer 30 on the side facing the first substrate 10 is an inclined surface with respect to the light exit surface 13. It is understood that, in other embodiments, other relevant layers (e.g., overcoating layers) disposed on the first substrate 10 may also be disposed to be inclined with respect to the light emitting surface 13, so as to realize that the surface of the liquid crystal layer 30 facing the first substrate 10 is inclined with respect to the light emitting surface 13. In one embodiment, the first structural layer 41 may be an overcoat layer (Over Coat) disposed on the first substrate 10.
Fig. 6 is an enlarged schematic view of a portion B in fig. 5. As shown in fig. 6, in one embodiment, the surface of the first structure layer 41 facing the liquid crystal layer 30 may be inclined at an angle θ with respect to the first substrate 10, and θ may be 2 ° to 8 °. It is easy to understand that the thickness of the first structural layer 41 is limited due to the requirement of the thickness of the display panel. If the angle theta is less than 2 degrees, although the contrast of the display panel at a specific viewing angle can be increased, the higher specification requirements of customers cannot be met; the angle θ is larger than 8 °, the thickness of the structural layer needs to be increased, resulting in an increase in the thickness of the display panel.
Fig. 7 is a schematic view of a display panel composed of the pixel structure according to the embodiment of the invention, which is vertically arranged for display. Fig. 7 shows only one of the pixel structures of the display panel. In one embodiment, the display panel is vertically disposed, and a surface of the first substrate 10 facing away from the second substrate 10 is a light emitting surface. In order to satisfy the specification of the region a shown in fig. 1, such that the top-bottom viewing angle of the display panel is symmetrical, the surface of the first structure layer 41 facing the liquid crystal layer 30 is inclined with respect to the light emitting surface 13, such that the distance between the surface of the first structure layer 41 facing the liquid crystal layer 30 and the first substrate 10 gradually decreases from top to bottom, i.e., m1> m2, i.e., the distance between the surface of the first structure layer 41 facing the liquid crystal layer 30 and the light emitting surface 13 gradually decreases from top to bottom, as shown in fig. 7.
As shown in fig. 7, the liquid crystal layer 30 is vertically and obliquely arranged, and m1> m2 is equivalent to vertically and obliquely arranging the display screen such that the center line 31 of the display screen is shifted toward the upper right, thereby improving the contrast of the viewing angle corresponding to the shifting direction of the center line 31. In fig. 7, the central line 31 of the display screen is shifted toward the upper right, so that the difference between the upper and lower viewing angles of the display panel is reduced compared to fig. 4, so that the upper and lower viewing angles tend to be symmetrical with respect to the central line 31, the contrast of the upper viewing angle is improved, and the NG risk is reduced. When the display panel shown in fig. 7 is applied to products such as vehicle-mounted display, public display and the like, the contrast of the display device at a specific visual angle can be increased, and the higher specification requirements of customers are met.
In one embodiment, the angle θ may be 5 °. When the angle θ is 5 °, in fig. 7, the center line 31 of the display screen is shifted 5 ° toward the upper right, and thus α '═ β' ═ 15 °, not only satisfies the requirements of the a-zone upper view angle of 20 ° and the lower view angle of 10 °, but also the a-zone upper view angle and the lower view angle are symmetrical with respect to the center line 31.
The contrast ratio of the upper viewing angle and the lower viewing angle of the area a of the display panel shown in fig. 7 was measured to obtain the results shown in table 2.
Table 2 results of the area a contrast ratio of the display panel shown in fig. 7
| Zone A | UL (left upper view angle) | UR (Right upper view angle) | DL (left lower view angle) | DR (Right lower view angle) |
| Contrast ratio | 702 | 685 | 692 | 699 |
As can be seen from the results in table 2, compared with the panel shown in fig. 4, the upper and lower viewing angles of the area a of the display panel shown in fig. 7 are 31-symmetric with respect to the middle, which improves the contrast of the upper viewing angle, effectively reduces the contrast difference between the upper viewing angle and the lower viewing angle, and improves the symmetry of the contrast of the upper viewing angle and the lower viewing angle, so that the upper viewing angle of the area a meets the requirements of products of specific specifications (for example, the German5.0 specification contrast >650), thereby avoiding the problems of too large range of the lower viewing angle of the area a, excessive performance, and reducing the risk of NG.
As shown in fig. 5, the pixel structure may further include a second structure layer 42. The second structure layer 42 is disposed on a side of the second substrate 20 facing the liquid crystal layer 30. The liquid crystal layer 30 is disposed between the first structural layer 41 and the second structural layer 42. In one embodiment, the second structural layer 42 may be an overcoat layer disposed on the second substrate 20.
In order to further improve the display quality of the display panel, as shown in fig. 7, the surface of the second structure layer 42 facing the liquid crystal layer 30 and the surface of the first structure layer 41 facing the liquid crystal layer 30 are parallel to each other. Therefore, the thickness of the liquid crystal layer 30 is uniform, i.e., the thickness d1 of the upper edge of the liquid crystal layer 30 is equal to the thickness d2 of the lower edge, and d1 is equal to d2, so that the display uniformity of the display panel is ensured.
In this embodiment, the material of the first structural layer and the second structural layer includes a resin material, such as a photoresist material.
