It should be understood that those skilled in the art would recognize that the present disclosure may be practiced without these specific details. In other embodiments, well-known structures and processes are not described in detail to avoid obscuring the description of the present disclosure with unnecessary detail. Thus, the present disclosure is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in the present disclosure.
Embodiments of the present disclosure provide display panels, which will be described in detail below.
Referring to FIG. 1, it is a schematic view of light-emitting chips of a display panel in related art. The display panel shown in FIG. 1 includes a plurality of light-emitting chips arranged in an array. It should be noted that the light-emitting chip in the present disclosure is generally a flip chip, which has disadvantage of asymmetry of left and right light patterns, which leads to color deviation of the display panel in side-views.
In order to solve the problem of color deviation of the display panel in side-views, the present disclosure provides a new design structure of the light-emitting chip. As shown in FIG. 2, it is a schematic view of light-emitting chips of a display panel according to an embodiment of the present disclosure. In the embodiment shown in FIG. 2, only the structures of some light-emitting chips in the display panel are shown, but not all the light-emitting chips in the complete display panel are included. It should be noted that, in the embodiment shown in FIG. 2, the display panel also includes multiple columns of light-emitting chips arranged in an array, and each light-emitting chip includes an N pole and a P pole, and the N pole and the P pole are structures of the light-emitting chip itself. In addition, multiple light-emitting chips in any column of the multiple columns of light-emitting chips are arranged to share a common N pole or a common P pole.
Referring to FIG. 2, in the embodiment shown in FIG. 2, the display panel includes adjacent first light-emitting area 100 and second light-emitting area 200. At least one column of light-emitting chips 10 are arranged in the first light-emitting area 100, and at least one column of light-emitting chips 10 are arranged in the second light-emitting area 200. The light-emitting chips 10 in a first column in the first light-emitting area 100 are arranged to share a common N pole or a common P pole, and the light-emitting chips in a second column in the second light-emitting area 200 are also arranged to share a common N pole or a common P pole. That is, the N poles of the multiple light-emitting chips are arranged at same ends, or the P poles of the multiple light-emitting chips are arranged at same ends. In the embodiment shown in FIG. 2, multiple light-emitting chips form an array structure of multiple rows and multiple columns. The N poles of multiple light-emitting chips in a same column are connected to a same scan line, or the P poles of multiple light-emitting chips in a same column are connected to a same scan line.
At the same time, in the embodiment shown in FIG. 2, the light-emitting chips 10 in the first column and the light-emitting chips 20 in the second column are mirror-symmetrically arranged. Such arrangement can make the N poles and P poles of the light-emitting chips 10 in the first column mirror symmetrical to the N poles and P poles of the light-emitting chips 20 in the second column. Specifically, the N poles of the light-emitting chips 10 in the first column and the N poles of the light-emitting chips 20 in the second column are mirror-symmetrical, and the P poles of the light-emitting chips 10 in the first column and the P poles of the light-emitting chips 20 in the second column are mirror-symmetrical. Referring to FIG. 1, although multiple light-emitting chips in the related art shown in FIG. 1 are also arranged in an array, the scan lines corresponding to each of the multiple light-emitting chips are arranged on the right or left side of the light-emitting chip. For the plurality of light-emitting chips provided by the present disclosure shown in FIG. 2, some light-emitting chips are provided with corresponding scan lines arranged on their left sides, and another light-emitting chips are provided with corresponding scan lines arranged on their right sides. In this way, the plurality of light-emitting chips presents as a mirror-symmetrical structure.
For the first column of light-emitting chips 10 and the second column of light-emitting chips 20 that are mirror-symmetrical, such arrangement makes the electrodes having same polarity (N pole or P pole) of the light-emitting chips in different columns be located on an outside or inside of the whole structure at the same time. Specifically referring to FIG. 2, the P poles of the light-emitting chips 10 in the first column are located on the outside, and the N poles of the light-emitting chips 10 in the first column are located on the inside. Since the second column of light-emitting chips 20 and the first column of light-emitting chips 10 are mirror-symmetrical, the P poles of the light-emitting chips in the second column are also located on the outside, and the N poles of the light-emitting chips in the second column are located on the inside. Only in this way can a mirror-symmetrical structure be achieved. At this time, the P poles of the light-emitting chips in the first column and the P poles of the light-emitting chips in the second column adjacent to the first column are located on the outer sides, and there will be no color deviation in side-views caused by different electrodes due to the N poles and P poles being located on the outermost sides at the same time.
The display panel provided by the present disclosure includes a plurality of light-emitting chips arranged in an array, and each light-emitting chip includes the N pole and the P pole. Multiple light-emitting chips are arranged to share a common N pole or a common P pole. The plurality of light-emitting chips arranged in an array include adjacent first column of light-emitting chips and second column of light-emitting chips, and light-emitting chips in the first column and the light-emitting chips in the second column are mirror-symmetrically arranged. In the display panel provided by the present disclosure, two adjacent columns of light-emitting chips are mirror-symmetrically arranged, so as to avoid the problem of asymmetric light-emitting brightness curves of the light-emitting chips at the left and right sides, thereby eliminating the problem of color deviation when the display panel is viewed from sides.
In the above embodiment, since the first column of light-emitting chips 10 and the second column of light-emitting chips 20 are mirror-symmetrical, a minimum distance D1 between the N pole of the light-emitting chip 10 in the first column and the N pole of the light-emitting chip 20 in the second column is less than a minimum distance D2 between the N pole of the light-emitting chip 10 in the first column and the P pole of the light-emitting chip 20 in the second column.
Referring to FIG. 1 and FIG. 2, the adjacent first column of light-emitting chips 10 and the second column of light-emitting chips 20 are taken as an example.
For the first column of light-emitting chips 10 in FIG. 1, the N poles are located on the outside, and the P poles are located on the inside; and for the second column of light-emitting chips 20 in FIG. 1, the N poles are located on the inside, and the P poles are located on the outside. In FIG. 1, the P poles of the light-emitting chips 10 in the first column are inserted between the N poles of the light-emitting chips 10 in the first column and the N poles of the light-emitting chips 20 in the second column. At this time, the N poles of the light-emitting chips 10 in the first column and the P poles of the light-emitting chips 20 in the second column are respectively located on the outsides, resulting in the problem of color deviation in side-views.
For the first column of light-emitting chips 10 and the second column of light-emitting chips 20 in FIG. 2, both the N poles of the light-emitting chips 10 in the first column and the N poles of the light-emitting chips 20 in the second column are located on the inside, and both the P poles of the light-emitting chips 10 in the first column and the P poles of the light-emitting chips 20 in the second column are located on the outside. The P poles of the light-emitting chips 10 in the first column or the P poles of the light-emitting chips 20 in the second column are not inserted between the N poles of the light-emitting chips 10 in the first column and the N poles of the light-emitting chips 20 in the second column. This also means that the minimum distance D1 between the N pole of the light-emitting chip in the first column and the N pole of the light-emitting chip in the second column is less than the minimum distance D2 between the N pole of the light-emitting chip in the first column and the P pole of the light-emitting chip in the second column. On the contrary, in the display panel shown in FIG. 1, a minimum distance between the N pole of the light-emitting chip in the first column and the N pole of the light-emitting chip in the second column is greater than a minimum distance between the N pole of the light-emitting chip in the first column and the P pole of the light-emitting chip in the second column.
The above embodiment describes a case where the N poles are located on the insides. In other embodiments, the P poles of the light-emitting chips 10 in the first column and the P poles of the light-emitting chips 20 in the second column may also be located on the insides. At this time, a minimum distance between the P pole of the light-emitting chip 10 in the first column and the P pole of the light-emitting chip 20 in the second column is also less than a minimum distance between the P pole of the light-emitting chip 10 in the first column and the N pole of the light-emitting chip 20 in the second column. Whether the P poles of the light-emitting chips 10 in the first column and the P poles of the light-emitting chips 20 in the second column are located on the inside or outside at the same time, the light-emitting chips 10 in the first column and the light-emitting chips 20 in the second column are arranged as a mirror-symmetrical structure, and the N-poles and P-poles of the light-emitting chips 10 in the first column and the N-poles and P-poles of the light-emitting chips 20 in the second column also arranged as a mirror-symmetrical structure. This arrangement makes the electrodes located on the outside have a same type, such as all N poles or all P poles, and also makes the electrodes on the outside of the entire display panel have the same type, such as all N poles or all P poles, thereby avoiding the problem of color deviation caused by different electrodes.
In an actual display panel, at least two adjacent columns of light-emitting chips are generally arranged as a mirror-symmetrical structure, instead of two separate light-emitting chips being arranged as a mirror-symmetrical structure. It should be noted that the embodiment shown in FIG. 2 only shows some light-emitting chips arranged mirror-symmetrically, and the structures of other light-emitting chips other than the light-emitting chip shown in FIG. 2 are not limited. Arranging some of the light-emitting chips in the display panel according to the structure shown in FIG. 2 can alleviate the problem of color deviation to a certain extent.
The above embodiment describes that there are only the first column of light-emitting chips 10 in the first light-emitting area 100, only the second column of light-emitting chips 20 in the second light-emitting area 200, and the two adjacent columns of light-emitting chips are arranged to be mirror-symmetrical. In some other embodiments, more columns of light-emitting chips may be further arranged in the first light-emitting area 100, and similarly, more columns of light-emitting chips may be further arranged in the second light-emitting area 200.
As shown in FIG. 3, it is a schematic view of light-emitting chips of a display panel according to another embodiment of the present disclosure. In the embodiment shown in FIG. 3, there are four or more even-numbered columns of light-emitting chips adjacent to each other in sequence. Light-emitting chips in the first light-emitting area 100 may include the first column of light-emitting chips 10 and a third column of light-emitting chips 30 adjacent to the first column. Light-emitting chips in the second light-emitting area 200 may include the second column of light-emitting chips 20 and a fourth column of light-emitting chips 40 adjacent to the second column. The even-numbered columns of light-emitting chips include the first column of light-emitting chips 10 and the second column of light-emitting chips 20 that are mirror-symmetrical, and the first column of light-emitting chips and the second column of light-emitting chips are located at a middle position of the even-numbered columns of light-emitting chips. The third column of light-emitting chips 30 is located on the left side of the first column of light-emitting chips 10, and the fourth column of light-emitting chips 40 is located on the right side of the second column of light-emitting chips 20.
In the embodiment shown in FIG. 3, not only the first column of light-emitting chips 10 and the second column of light-emitting chips 20 are mirror-symmetrical, but the third column of light-emitting chips and the first column of light-emitting chips 30 are also mirror-symmetrical, and the second column of light-emitting chips 20 and the fourth column of light-emitting chips 40 are also arranged mirror-symmetrically. The polarity of the two columns of light-emitting chips in the first light-emitting area on the left is PNNP from left to right, and the polarity of the two columns of light-emitting chips in the second light-emitting area on the right is PNNP from left to right. An overall structure composed of the first column of light-emitting chips 10 and the third column of light-emitting chips 30 in the first light-emitting area 100 and an overall structure composed of the second column of light-emitting chips 20 and the fourth column of light-emitting chips 40 in the second light-emitting area 200 are mirror symmetrical. For the embodiment shown in FIG. 3, the light-emitting chips in different light-emitting areas are arranged in a same manner, so that under a premise that the light-emitting chips in a single light-emitting area maintain a mirror-symmetrical structure, an overall structure formed by multiple light-emitting areas is also mirror-symmetrical.
At this time, a minimum distance between the N pole of the light-emitting chip in the third column and the N pole of the light-emitting chip in the first column is less than a minimum distance between the N pole of the light-emitting chip in the third column and the P pole of the light-emitting chip in the first column, and a minimum distance between the N pole of the light-emitting chip in the second column and the N pole of the light-emitting chip in the fourth column is less than a minimum distance between the N pole of the light-emitting chip in the second column and the P pole of the light-emitting chip in the fourth column. In other words, the electrodes of the third column of light-emitting chips 30, the first column of light-emitting chips 10, the second column of light-emitting chips 20, and the fourth column of light-emitting chips 40 are arranged in an order of PNNP-PNNP, and the whole structure is also a mirror symmetrical structure. The electrodes located on the outermost sides of the whole structure are the same type of electrodes, all of which are P poles, so this arrangement can also avoid the problem of color deviation caused by different electrodes.
As shown in FIG. 4, it is a schematic view of light-emitting chips of a display panel according to another embodiment of the present disclosure. In FIG. 4, the display panel also includes four or more even-numbered columns of light-emitting chips that are adjacent to each other in sequence. Light-emitting chips in the first light-emitting area 100 may include the first column of light-emitting chips 10 and a third column of light-emitting chips 30 adjacent to the first column. Light-emitting chips in the second light-emitting area 200 may include the second column of light-emitting chips 20 and a fourth column of light-emitting chips 40 adjacent to the second column.
But different from the embodiment shown in FIG. 3, in the embodiment shown in FIG. 4, a minimum distance between the N pole of the light-emitting chip in the third column and the N pole of the light-emitting chip in the first column is greater than a minimum distance between the N pole of the light-emitting chip in the third column and the P pole of the light-emitting chip in the first column, and a minimum distance between the N pole of the light-emitting chip in the second column and the N pole of the light-emitting chip in the fourth column is greater than a minimum distance between the N pole of the light-emitting chip in the second column and the P pole of the light-emitting chip in the fourth column. In other words, the electrodes of the third column of light-emitting chips 30, the first column of light-emitting chips 10, the second column of light-emitting chips 20, and the fourth column of light-emitting chips 40 are arranged in an order of NPPN-NPPN, and the whole structure is also a mirror symmetrical structure. The electrodes located on the outermost sides of the whole structure are the same type of electrodes, all of which are N poles, so this arrangement can also avoid the problem of color deviation caused by different electrodes.
As shown in FIG. 5, it is a schematic view of light-emitting chips of a display panel according to another embodiment of the present disclosure. In the embodiment shown in FIG. 5, the display panel also includes four or more even-numbered columns of light-emitting chips that are adjacent to each other in sequence. Light-emitting chips in the first light-emitting area 100 may include the first column of light-emitting chips 10 and a fifth column of light-emitting chips 50 adjacent to the first column. Light-emitting chips in the second light-emitting area 200 may include the second column of light-emitting chips 20 and a sixth column of light-emitting chips 60 adjacent to the second column. Herein, an arrangement of the P poles and the N poles of the fifth column of light-emitting chips 50 is the same as an arrangement of the P poles and the N poles of the first column of light-emitting chips 10, and an arrangement of the P poles and the N poles of the second column of light-emitting chips 20 is the same as an arrangement of the P poles and the N poles of the sixth column of light-emitting chips 60. The light-emitting chips 50 in the fifth column and the light-emitting chips 60 in the sixth column are mirror-symmetrical, and the light-emitting chips 10 in the first column and the light-emitting chips 20 in the second column are mirror-symmetrical.
Different from the embodiments shown in FIG. 3 and FIG. 4, in which, adjacent two columns of light-emitting chips in the first light-emitting area or the second light-emitting area are also mirror-symmetrically arranged, in the display panel shown in FIG. 5, the fifth column of light-emitting chips 50 and the first column of light-emitting chips 10 adjacent to each other in the first light-emitting area 100 are not mirror-symmetrically arranged, and similarly, the light-emitting chips 20 in the second column and the light-emitting chips 60 in the sixth column adjacent to each other in the second light-emitting area 200 are not mirror-symmetrically arranged. An overall structure composed of multiple columns of light-emitting chips in the first light-emitting area and an overall structure composed of multiple columns of light-emitting chips in the second light-emitting area 200 are still mirror-symmetrically arranged, so as to ensure that electrodes at the outermost of the overall structure are still same, such as both are N poles or both are P poles, so as to avoid the problem of color deviation.
In the embodiment shown in FIG. 5, a minimum distance between the N pole of the light-emitting chip in the fifth column and the P pole of the light-emitting chip in the first column is less than a minimum distance between the N pole of the light-emitting chip in the fifth column and the N pole of the light-emitting chip in the first column, and a minimum distance between the N pole of the light-emitting chip in the second column and the P pole of the light-emitting chip in the sixth column is greater than a minimum distance between the N pole of the light-emitting chip in the second column and the N pole of the light-emitting chip in the sixth column. At this time, the electrodes of the fifth column of light-emitting chips 50, the first column of light-emitting chips 10, the second column of light-emitting chips 20, and the sixth column of light-emitting chips 60 are arranged in an order of PNPN-NPNP. Although multiple columns of light-emitting chips in a single display area are not mirror-symmetrically arranged, the entire structure is also mirror-symmetrically arranged. The electrodes located on the outermost sides of the whole structure are the same type of electrodes, all of which are P poles, so this arrangement can also avoid the problem of color deviation caused by different electrodes.
As shown in FIG. 6, it is a schematic view of light-emitting chips of a display panel according to another embodiment of the present disclosure. In the embodiment shown in FIG. 6, the display panel also includes four or more even-numbered columns of light-emitting chips that are adjacent to each other in sequence. Light-emitting chips in the first light-emitting area 100 may include the first column of light-emitting chips 10 and the fifth column of light-emitting chips 50 adjacent to the first column. Light-emitting chips in the second light-emitting area 200 may include the second column of light-emitting chips 20 and the sixth column of light-emitting chips 60 adjacent to the second column. Herein, an arrangement of the P poles and the N poles of the fifth column of light-emitting chips 50 is the same as an arrangement of the P poles and the N poles of the first column of light-emitting chips 10, and an arrangement of the P poles and the N poles of the second column of light-emitting chips 20 is the same as an arrangement of the P poles and the N poles of the sixth column of light-emitting chips 60. The light-emitting chips 50 in the fifth column and the light-emitting chips 60 in the sixth column are mirror-symmetrical, and the light-emitting chips 10 in the first column and the light-emitting chips 20 in the second column are mirror-symmetrical.
Different from the embodiment shown in FIG. 5, in the display panel shown in FIG. 6, a minimum distance between the N pole of the light-emitting chip in the fifth column and the P pole of the light-emitting chip in the first column is greater than a minimum distance between the N pole of the light-emitting chip in the fifth column and the N pole of the light-emitting chip in the first column, and a minimum distance between the N pole of the light-emitting chip in the second column and the P pole of the light-emitting chip in the sixth column is less than a minimum distance between the N pole of the light-emitting chip in the second column and the N pole of the light-emitting chip in the sixth column. At this time, the electrodes of the fifth column of light-emitting chips 50, the first column of light-emitting chips 10, the second column of light-emitting chips 20, and the sixth column of light-emitting chips 60 are arranged in an order of NPNP-PNPN. Although multiple columns of light-emitting chips in a single display area are not mirror-symmetrically arranged, the entire structure is also mirror-symmetrically arranged. The electrodes located on the outermost sides of the whole structure are the same type of electrodes, all of which are N poles, so this arrangement can also avoid the problem of color deviation caused by different electrodes.
It should be noted that, in the embodiments of the present disclosure, there is no restriction on the direction of the N pole and the P pole, and it is only necessary to ensure that the light-emitting chips on a same column share a common N pole or a common P pole, and it is sufficient to ensure that the multiple columns of light-emitting chips can be mirror-symmetrical (mainly mirror-symmetrical to the electrodes). A number of columns in the light-emitting chips in the first light-emitting area 100 and a number of columns in the light-emitting chips in the second light-emitting area 200 are generally same, so as to ensure that the overall structure is mirror-symmetrical. When multiple columns of light-emitting chips are arranged in both the first light-emitting area 100 and the second light-emitting area 200, it doesn't matter whether the multiple columns of light-emitting chips in the first light-emitting area 100 are mirror-symmetrical or not, and similarly, it doesn't matter whether the multiple columns of light-emitting chips in the second light-emitting area 200 are mirror-symmetrical or not.
