Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The display area 10 of the present display panel is shown in fig. 1, in which the display area 10 in fig. 1 is composed of a plurality of pixel units in fig. 3, and the pixel units in fig. 3 include R/G/B sub-pixel structures and driving circuit units (not shown here). In the practical application as shown in fig. 2, when the bottom of the display device faces upward and the top of the display device faces downward, the viewing angle (the angle between the eye line of sight and the horizontal angle) is large when the display device is placed in the vertical direction and rotated around the lower frame line (short side) as the axis, and the rainbow phenomenon occurs. The inventor researches that the attenuation speed of each sub-pixel structure is different, the attenuation speed is G > R > B, and when the rotation observation is carried out from 60 degrees to 80 degrees of a large visual angle, light beams firstly pass through the supporting structure and then exit through the glass cover plate, so that the attenuation degree of the sub-pixel structure G with the highest attenuation speed is increased, the rainbow line phenomenon is caused under the large visual angle, and the display defect problem is caused.
Based on this, the display panel, the design method and the display device provided by the embodiment of the invention ensure that the first light emitting direction of the first sub-pixel structure is not blocked by the support structure, so as to further slow down the brightness attenuation of the first sub-pixel structure under the observation of a large viewing angle, and improve the first sub-pixel structure of the large viewing angle rainbow line problem generated by the observation of the first light emitting direction.
The following is a detailed description of examples.
Fig. 4 is a schematic structural diagram of a display panel according to an embodiment of the present invention.
The display panel may be an active matrix organic light emitting diode display panel, referring to fig. 4, the display panel includes a plurality of sub-pixel structures for emitting light, wherein the sub-pixel structures include a first sub-pixel structure 20, and the first sub-pixel structure 20 has the fastest brightness decay speed among the plurality of sub-pixel structures;
The plurality of support structures 50 are located between any two adjacent sub-pixel structures, wherein the first sub-pixel structure 20 corresponds to a first light emitting direction (a direction indicated by an arrow), and the support structures 50 around the first sub-pixel structure 20 are located in a direction other than the first light emitting direction of the first sub-pixel structure 20.
Wherein the support structure may include an organic PR glue Support Post (SPC), and the support structure may be located in a direction other than the first light emitting direction of the first sub-pixel light emitting unit. The organic PR glue support column is also used for supporting an R/G/B evaporation Mask, a glass cover plate (ENCAP) and a glass substrate (LTPS).
It is understood that LTPS is one active layer forming mode different from Liquid crystal display (Liquid CRYSTAL DISPLAY, LCD), and the active layers of the remaining LCDs have different functions.
In a preferred embodiment of practical application, a supporting structure is arranged between any two adjacent sub-pixel structures, and the supporting structure is arranged in a direction except for the first light emitting direction of the first sub-pixel structure, so that the first light emitting direction of the first sub-pixel structure is enabled to be free of shielding by the supporting structure, the brightness attenuation speed of the first sub-pixel structure under a large visual angle is further slowed down, and the occurrence of large visual angle rainbow patterns during the observation of the first light emitting direction is further avoided.
It should be noted that the first light emitting direction shown in fig. 4 is only an example, and is not limited thereto, and is only used for describing the arrangement positional relationship of the corresponding first sub-pixel structure 20 and the support structure 50 when the first light emitting direction is shown in fig. 4. As an alternative example, the first light emitting direction extends along a long side direction of the display panel.
In some embodiments, the plurality of sub-pixel structures further includes a second sub-pixel structure 30, a third sub-pixel structure 40, and the first sub-pixel structure 20 may be a green sub-pixel structure (G sub-pixel structure) that may be used to emit green light. The second sub-pixel structure 30 may be a blue sub-pixel structure (B sub-pixel structure), and the third sub-pixel structure 40 may be a red sub-pixel structure (R sub-pixel structure).
Illustratively, the first sub-pixel structure in the display panel may include a plurality of sub-pixel structures. The plurality of sub-pixel structures are arranged in an array in the active matrix organic light emitting diode display panel, the first light emitting direction corresponds to the column arrangement direction of the green sub-pixel structures, and the support structures around the first sub-pixel structures correspond to the row arrangement direction of the green sub-pixel structures. In other words, the first light emitting direction is the same as the column arrangement direction of the green sub-pixel structure, i.e., the column arrangement direction of the green sub-pixel structure coincides with the long side direction of the display panel.
In some embodiments, the supporting structure around the first sub-pixel structure 20 may be located in the first light emitting direction of the second sub-pixel structure 30, and the first light emitting direction of the second sub-pixel structure 30 extends along the long side direction of the display panel.
In some embodiments, the support structures around the first sub-pixel structure 20 are located in the first light emitting direction of the third sub-pixel structure 40, and the first light emitting direction of the third sub-pixel structure 40 extends along the long side direction of the display panel.
In some embodiments, the second sub-pixel structure 30 and the third sub-pixel structure 40 are adjacently arranged in the row direction, and a line formed by a center of the second sub-pixel structure 30 and a center of the third sub-pixel structure 40 adjacently arranged in the row direction is parallel to a short side direction of the display panel.
Illustratively, the second sub-pixel structure 30 includes a third sub-pixel structure 40 adjacent to the third sub-pixel structure 40 in the row direction and a third sub-pixel structure 40 adjacent to the third sub-pixel structure in the column direction, wherein the center of the third sub-pixel structure 40 arranged in the same row and adjacent to the third sub-pixel structure is parallel to the short side direction of the display panel, and the line connecting the center of the second sub-pixel structure 30.
As shown in fig. 4, it can be seen that the second sub-pixel structure 30 and the third sub-pixel structure 40 are disposed around the first sub-pixel structure 20, and the central lines of the two second sub-pixel structures 30 and the two third sub-pixel structures 40 form a trapezoid, and the bottom of the trapezoid is parallel to the short side direction of the display panel.
It should be noted that the center of the sub-pixel structure may be an opening or a window of the pixel semiconductor device.
In some embodiments, the first light emitting direction includes a large viewing angle direction, which is an observation angle direction formed by intersecting light rays emitted from two ends of the display panel in an eyeball of a user, and the large viewing angle direction may be 60 ° -80 °. When the supporting structure corresponds to the row arrangement of the green sub-pixel structure, a user observes the display panel which is placed in a vertical state and rotates by taking the lower frame line as an axis according to the large viewing angle direction, and at the moment, the supporting structure does not shade the first light emitting direction of the first sub-pixel structure, so that the attenuation degree of the brightness of the green sub-pixel can be reduced, and the rainbow line defect caused by the brightness attenuation of the green sub-pixel under the condition of the large viewing angle is further improved. The first light emitting direction may be understood as a direction in which the current user observes.
The inventor researches find that, because the attenuation degrees of the three sub-pixels of RGB are different, if the supporting structure shields the green sub-pixel structure with the highest attenuation degree, the difference between the attenuation of the green sub-pixel and the attenuation of the other two sub-pixels is aggravated, so that rainbow lines appear to cause poor display, and if the supporting structure shields the blue sub-pixel structure and/or the red sub-pixel structure with relatively smaller attenuation degree, the negative influence on the display effect is smaller.
In some embodiments, the user may observe from any direction of the display panel, but the user group has several directions of observation that are relatively commonly used, so that the display effect of the directions of observation that are commonly used by the user can be preferentially ensured. The first sub-pixel structure is provided with a plurality of light emitting directions, and the light emitting directions are provided with different observation levels; the support structure around the first sub-pixel structure is located in a second light-emitting direction which is lower than the observation level of the first light-emitting direction in the plurality of light-emitting directions. If the supporting structure is likely to be shielded compared with some sub-pixel structures, the supporting structure can be arranged in a less-common light emitting direction, and the sub-pixel structures in the less-common light emitting direction are shielded, so that the attenuation degree of the green sub-pixel structures in the first light emitting direction which are commonly used by users and have higher observation level is slowed down, and the rainbow phenomenon in the common direction is avoided.
On the basis of the foregoing embodiments, the support structure may be further configured according to attenuation levels of three sub-pixels, where, illustratively, the plurality of sub-pixel structures correspond to a plurality of categories, the sub-pixel structures of the same category are used to emit light of the same color, the pixel structures of different categories correspond to different observation levels, and the support structure around the first sub-pixel structure is located in the first light emitting direction of the second sub-pixel structure lower than the observation level of the first sub-pixel structure. That is, a sub-pixel with a higher level of attenuation may have a higher observed level than a sub-pixel with a lower level of attenuation, and the support structure may be placed around the sub-pixel structure with a lower level of attenuation. Even if the sub-pixel structure with lower attenuation degree is shielded, an abnormal display result does not appear.
In some embodiments, the display panel provided by the embodiment of the invention further includes a driving circuit and a packaging area.
In the practical application process, the display panel can comprise a glass cover plate, a display layer and a glass substrate, wherein the glass substrate is arranged on the bottom layer, the display layer is arranged on the glass substrate, and the glass cover plate is arranged on the display layer. The display layer is provided with a display area for realizing a display function, a driving circuit for driving the display area to work in a luminous mode is arranged at the periphery of the display area, a packaging area is arranged at the periphery of the driving circuit, and the packaging area packages the components through packaging materials.
In some embodiments, the present invention further provides a display device such as a display panel. The display device can comprise terminal equipment such as a mobile phone, a tablet and the like, can observe in a large visual angle in the bottom direction, avoids the problem of rainbow lines, and realizes clear display of images.
In some embodiments, as shown in fig. 5, an embodiment of the present invention further provides a method for designing a display panel, including the following steps:
Step S102, an initial design of an active matrix OLED display panel, a first sub-pixel structure and a first light emitting direction are obtained, wherein the initial design comprises a plurality of sub-pixel structures and a plurality of supporting structures positioned between any two adjacent sub-pixel structures, and the sub-pixel structures are used for emitting light.
In the embodiment of the present invention, fig. 3 shows an example of the initial design, where the sub-pixel structures are arranged in the display area according to the source line direction, the supporting structure is between any two adjacent sub-pixel structures, and the supporting structure 50 corresponds to the column arrangement direction of the first sub-pixel structure 20. At this time, the connection line between the opening of the third sub-pixel structure 40 and the opening of the second sub-pixel structure 30 is a trapezoid (as shown by a dotted line), wherein the upper and lower bases of the trapezoid may be parallel to the long-side direction (left and right frame lines) of the display panel.
In step S104, it is determined whether the support structures around the first sub-pixel structure are located in the first light emitting direction of the first sub-pixel structure based on the initial design.
And S106, if so, performing position optimization on the initial design as a whole to obtain an optimal design, wherein the support structures around the first sub-pixel structure in the optimal design are not positioned in the first light emitting direction of the first sub-pixel structure.
In practical embodiments, the initial design as shown in fig. 3 may exhibit rainbow patterns when viewed from the bottom of the display device during large viewing angles. The problem of rainbow lines is solved by optimizing the position of the support structure in the design stage so that the first sub-pixel structure is not shielded.
Wherein the position optimization may include rotation and/or mirroring. In some embodiments, the initial design is rotated 90 degrees clockwise and mirror-symmetrical about the Y-axis; or the initial design is rotated 90 degrees anticlockwise and is mirror symmetrical about the X axis; or the initial design is mirror symmetrical about the Y-axis and rotated 90 degrees counterclockwise; or the original design is mirror-symmetrical about the X-axis and rotated 90 degrees further clockwise.
Illustratively, the display panel structure shown in fig. 4 is obtained by the above-described position optimization method, in which the connection line between the opening of the third sub-pixel structure and the opening of the second sub-pixel structure is a trapezoid (shown by a dotted line), wherein the upper and lower bottom sides of the trapezoid may be parallel to the short-side direction (upper and lower frame lines) of the display panel. The supporting structure corresponds to the row arrangement direction of the first sub-pixel structure, and the effect of improving the rainbow patterns with a large visual angle is achieved.
It should be noted that the opening of the first sub-pixel structure and the first light emitting direction do not change with the optimization of the position of the initial design. The structure of the display panel is only a part of the structure shown in fig. 3 and 4, and the rest is the same, not all of which are shown here, as will be clear to a person skilled in the art.
