Description

Display panel and manufacturing method thereof and spliced display screen

Technical Field

本申请涉及显示领域，特别涉及一种显示面板及其制作方法与拼接式显示屏。The present application relates to the field of display, and in particular to a display panel and a manufacturing method thereof, and a spliced display screen.

Background Art

Mini-LED（次毫米级发光二极管）是新一代显示技术，比现有的OLED（有机发光二极管）显示技术亮度更高、发光效率更好，但功耗更低，Mini-LED技术将LED结构设计进行薄膜化、微小化、阵列化，每一点像素都能定址控制及单点驱动发光、寿命长、应用范畴广。Mini-LED (sub-millimeter light-emitting diode) is a new generation of display technology. It has higher brightness and better luminous efficiency than the existing OLED (organic light-emitting diode) display technology, but lower power consumption. Mini-LED technology designs the LED structure into thin films, miniaturization, and arrays. Each pixel can be addressed and controlled and driven to emit light at a single point. It has a long life and a wide range of applications.

Mini-LED可用作直接显示，例如户外高清大面积显示，由于LED显示面板的尺寸越大，Mini-LED转移的难度越大，因此可一次性制作多块LED显示面面板，再将多块LED显示面板拼接成一个大显示屏，从而解决大量Mini-LED转移的良率问题，然而，在对多块LED显示面板进行拼接时，会出现由于LED显示面板的边缘的非显示区域的面积较大，导致相邻的LED显示面板之间的拼接缝处的非显示区的面积较大，从而导致拼接显示屏的拼接缝处的显示效果较差，进而导致拼接显示屏的整体视觉效果较差。Mini-LED can be used for direct display, such as outdoor high-definition large-area display. Since the larger the size of the LED display panel, the more difficult it is to transfer Mini-LED, multiple LED display panels can be made at one time, and then the multiple LED display panels can be spliced into a large display screen, thereby solving the yield problem of transferring a large number of Mini-LEDs. However, when splicing multiple LED display panels, the non-display area at the edge of the LED display panel is large, resulting in a large non-display area at the splicing seams between adjacent LED display panels, resulting in poor display effects at the splicing seams of the spliced display screen, and then resulting in poor overall visual effects of the spliced display screen.

SUMMARY OF THE INVENTION

本申请实施例提供一种显示面板及其制作方法与拼接式显示屏，可以缩小第一基板边缘的非显示区域的面积，使得显示面板可以实现极窄边框显示或者无边框显示，当对多块显示面板进行拼接以形成拼接式显示屏时，相邻的LED显示面板之间的拼接缝处的非显示区的面积缩小，从而可以提升拼接显示屏的拼接缝处的显示效果，进而提升拼接显示屏的整体视觉效果。The embodiments of the present application provide a display panel and a manufacturing method thereof, and a spliced display screen, which can reduce the area of the non-display region at the edge of the first substrate, so that the display panel can achieve an extremely narrow frame display or a frameless display. When multiple display panels are spliced to form a spliced display screen, the area of the non-display region at the splicing seams between adjacent LED display panels is reduced, thereby improving the display effect at the splicing seams of the spliced display screen, thereby improving the overall visual effect of the spliced display screen.

请参阅图2，需要说明的是，图2并非严格意义上的侧视图或剖视图，图2中，在从第二基板120至第一基板110的方向上，从第一连接件21和第二连接件22至第一导电层40的部分展示的为显示面板100的侧面，这部分结构用于展现第一连接件21通过位于显示面板100侧面的第一走线151与第一连接层42连接以及第二连接件22通过位于显示面板100侧面的第二走线152与第二连接层43连接的关系；从第三绝缘层50至第三导电层80的部分展示的为显示面板100的剖面结构，这部分结构用于体现第三连接层63经由位于显示面板100内部的第二通孔52与第一连接层42相连、第二连接层43经由位于显示面板100内部的第三通孔53与第一源极61相连的关系。Please refer to Figure 2. It should be noted that Figure 2 is not a side view or a cross-sectional view in a strict sense. In Figure 2, in the direction from the second substrate 120 to the first substrate 110, the portion from the first connector 21 and the second connector 22 to the first conductive layer 40 shows the side of the display panel 100. This portion of the structure is used to show the relationship that the first connector 21 is connected to the first connection layer 42 through the first wiring 151 located on the side of the display panel 100, and the second connector 22 is connected to the second connection layer 43 through the second wiring 152 located on the side of the display panel 100; the portion from the third insulating layer 50 to the third conductive layer 80 shows the cross-sectional structure of the display panel 100.

可以理解的是，本申请实施例提供的显示面板100，包括第一基板110和第二基板120。其中，第一基板110用于发光以实现画面显示，第二基板120用于承载为第一基板110输送电信号的导电线路。现有技术中，用于为第一基板110输送电信号的导电线路通常全部位于第一基板110上，从而会导致第一基板110边缘出现较大面积的非显示区域，当对多块显示面板100进行拼接以形成拼接式显示屏时，相邻的LED显示面板100之间的拼接缝处的非显示区的面积较大，从而导致拼接显示屏的拼接缝处的显示效果较差，进而导致拼接显示屏的整体视觉效果较差；而本申请通过将用于为第一基板110输送电信号的导电线路设置于与第一基板110层叠设置的第二基板120上，可以缩小第一基板110边缘的非显示区域的面积，使得显示面板100可以实现极窄边框显示或者无边框显示。当对多块显示面板100进行拼接以形成拼接式显示屏时，相邻的LED显示面板100之间的拼接缝处的非显示区的面积缩小，从而可以提升拼接显示屏的拼接缝处的显示效果，进而提升拼接显示屏的整体视觉效果。It can be understood that the display panel 100 provided in the embodiment of the present application includes a first substrate 110 and a second substrate 120. Among them, the first substrate 110 is used to emit light to realize picture display, and the second substrate 120 is used to carry a conductive circuit for transmitting electrical signals to the first substrate 110. In the prior art, the conductive circuits for transmitting electrical signals to the first substrate 110 are usually all located on the first substrate 110, which will cause a large area of non-display area to appear at the edge of the first substrate 110. When multiple display panels 100 are spliced to form a spliced display screen, the area of the non-display area at the splicing seam between adjacent LED display panels 100 is large, resulting in poor display effect at the splicing seam of the spliced display screen, and then resulting in poor overall visual effect of the spliced display screen; and the present application can reduce the area of the non-display area at the edge of the first substrate 110 by setting the conductive circuit for transmitting electrical signals to the first substrate 110 on the second substrate 120 stacked with the first substrate 110, so that the display panel 100 can achieve extremely narrow frame display or frameless display. When multiple display panels 100 are spliced to form a spliced display screen, the area of the non-display region at the splicing seams between adjacent LED display panels 100 is reduced, thereby improving the display effect at the splicing seams of the spliced display screen and further improving the overall visual effect of the spliced display screen.

The electrical signal output from the first drain 62 of the driving TFT can control the light emitting device 15 to light up or turn off, and the TFT device in the conductive circuit can be a switching TFT.

Exemplarily, the material of the second active layer 91 may include polysilicon.

请结合图4，在一些实施例中，导电线路可以包括在从第一基板110至第二基板120的方向上依次设置的第四导电层31和第五导电层32，也即是说，第二基板120背面的导电线路可以为多层分布。Please refer to Figure 4. In some embodiments, the conductive circuit may include a fourth conductive layer 31 and a fifth conductive layer 32 arranged in sequence in the direction from the first substrate 110 to the second substrate 120. That is, the conductive circuit on the back of the second substrate 120 can be distributed in multiple layers.

请结合图4，第二基板120可以包括在从第一基板110至第二基板120的方向上依次层叠设置的第二衬底16、第八绝缘层33、第四导电层31、第九绝缘层34和第五导电层32。4 , the second substrate 120 may include a second substrate 16 , an eighth insulating layer 33 , a fourth conductive layer 31 , a ninth insulating layer 34 and a fifth conductive layer 32 which are sequentially stacked in a direction from the first substrate 110 to the second substrate 120 .

Exemplarily, a via hole may be provided on the ninth insulating layer 34, so that the fifth conductive layer 32 is connected to the fourth conductive layer 31 via the via hole.

可以理解的是，当第四导电层31和第五导电层32相连时，相当于第四导电层31和第五导电层32共同构成了一个厚度较大的复合导电层，从而可以降低复合导电层的阻抗，进而有利于实现电信号的传输，可以避免电信号在传输过程中产生较大损失。可以理解的是，此时，第四导电层31和第五导电层32用于为第一基板110中同一个部件（第一导电层40、第二导电层60或第三导电层80）提供电信号。It is understandable that when the fourth conductive layer 31 and the fifth conductive layer 32 are connected, it is equivalent to that the fourth conductive layer 31 and the fifth conductive layer 32 together constitute a composite conductive layer with a large thickness, thereby reducing the impedance of the composite conductive layer, which is conducive to the transmission of electrical signals and can avoid large losses of electrical signals during the transmission process. It is understandable that at this time, the fourth conductive layer 31 and the fifth conductive layer 32 are used to provide electrical signals for the same component (the first conductive layer 40, the second conductive layer 60 or the third conductive layer 80) in the first substrate 110.

在另外一些实施例中，第四导电层31和第五导电层32也可以不相连（未图示），此时，第四导电层31和第五导电层32可以各自通过一条连接走线150与第一导电层40、第二导电层60和第三导电层80中的至少一个相连，也即是说，第四导电层31和第五导电层32分别用于为第一基板110中不同的部件（第一导电层40、第二导电层60或第三导电层80）提供电信号。In some other embodiments, the fourth conductive layer 31 and the fifth conductive layer 32 may also be unconnected (not shown). In this case, the fourth conductive layer 31 and the fifth conductive layer 32 may each be connected to at least one of the first conductive layer 40, the second conductive layer 60 and the third conductive layer 80 via a connecting line 150. In other words, the fourth conductive layer 31 and the fifth conductive layer 32 are respectively used to provide electrical signals for different components in the first substrate 110 (the first conductive layer 40, the second conductive layer 60 or the third conductive layer 80).

请结合图4，第一导电层40还可以包括第四连接层44，第四连接层44可以与第一栅极41连接，并且，第四连接层44可以通过连接走线150与第四导电层31和/或第五导电层32连接，从而将第四导电层31和/或第五导电层32的电信号传输至第一栅极41中。Please refer to Figure 4, the first conductive layer 40 may also include a fourth connecting layer 44, the fourth connecting layer 44 may be connected to the first gate 41, and the fourth connecting layer 44 may be connected to the fourth conductive layer 31 and/or the fifth conductive layer 32 through the connecting line 150, so as to transmit the electrical signal of the fourth conductive layer 31 and/or the fifth conductive layer 32 to the first gate 41.

The metal may include at least one of aluminum (Al), silver (Ag), tungsten (W), copper (Cu), nickel (Ni), chromium (Cr), molybdenum (Mo), titanium (Ti), platinum (Pt), tantalum (Ta), and neodymium (Nd).
