And the driving circuit layer 201 is formed on the region of the substrate 1032 corresponding to the recess 10a. By forming the concave portion 10a on the surface of the base 1032 far away from the driving substrate 101 and disposing the second display module 20 in the concave portion 10a, the step difference between the first display module 10 and the second display module 20 is further reduced, so that the flatness of the light emitting surface of the spliced display panel 1000 is further ensured, the shadow at the joint line PA is improved, the joint line of the spliced display panel 1000 is reduced or even eliminated, and the display taste is improved.
Referring to fig. 4 and fig. 6, fig. 6 is a schematic structural diagram of the second display module in fig. 4. The second display module 20 includes a driving circuit layer 201, a connection pad 202, and an LED chip 203 disposed on the driving circuit layer 201.

The LED chip 203 is electrically connected to the driving circuit layer 201 through the connection pad 202, and the driving circuit layer 201 is used to drive the LED chip 203 to emit light.
In some embodiments, the LED chip 203 may be a micro LED chip or a Mini LED chip. The second display module 20 adopts Micro-LEDs and Mini-LEDs to emit light for display, and Micro LED light emitting structures and Mini LED light emitting structures with smaller space can be manufactured by improving the process and the panel design. When the distance between the light emitting diodes of the Micro LED light emitting structure and the Mini LED light emitting structure is reduced, on one hand, higher resolution display can be realized in a narrow joint, and the display effect is enhanced; on the other hand, a borderless effect can be achieved visually, and fusion with the first display module 10 is better, so that the display screen is more continuous and complete.

Referring to fig. 7, fig. 7 is a schematic diagram of a second structure of a tiled display panel according to an embodiment of the application. The difference between the tiled display panel 1000 provided by the embodiment of the present application and the tiled display panel 1000 provided by fig. 4 is that the tiled display panel 1000 further includes a filling layer 108, and the filling layer 108 is filled in the recess 10a. Since the LED chip 203 is easily corroded by water and oxygen to cause the second display module 20 to fail, which affects the display effect of the tiled display panel 1000, the LED chip 203 and the connection pad 202 are encapsulated in the filler layer 108, preventing water and oxygen corrosion.
Referring to fig. 8, fig. 8 is a schematic diagram of a third structure of a tiled display panel according to an embodiment of the application. The difference between the tiled display panel 1000 provided by the embodiment of the present application and the tiled display panel 1000 provided by fig. 7 is that the slit S is filled with the optical adhesive (Optically Clear Adhesive, OCA) 107. When OCA optical cement is adopted for surface connection, the strength is higher. In addition, the OCA optical adhesive has high light transmittance and can effectively eliminate the gap S. The slit S is a small-pitch slit generated in the middle when the display panel 100 is spliced. The display effect is not generally affected because the distance of the gap is small. If the optical cement 107 is filled in the slit S, a more complete and continuous screen can be displayed. Therefore, the OCA optical adhesive not only can ensure the connection stability of two adjacent display panels 100, but also can make the surface of the product smoother, avoid the problem of uneven thickness, and further improve the display effect of the tiled display panel 1000.
In some embodiments, the material of the optical adhesive 107 is selected from one of silicone, acrylic, epoxy sealant, and polyurethane adhesive, or any combination thereof. In the application, the polymer material has high viscosity, high density and high light transmittance, so the embodiment of the application selects the optical materials with high water-oxygen barrier capability, such as organic silica gel, acrylic acid glue, epoxy sealant, polyurethane glue and the like, and has excellent optical performance while having high water-oxygen barrier capability. The optical adhesive 107 provided by the embodiment of the application can be directly attached to two adjacent frame areas AA without introducing an adhesive layer.
In some embodiments, the material of the filler layer 108 is the same as the material of the optical cement 107. The optical cement 107 has high light transmittance and does not affect the display of the second display module 20; furthermore, the optical adhesive 107 provided in the embodiment of the present application has strong capability of blocking water and oxygen, forms a barrier for blocking water and oxygen, completely wraps the entire second display module 20, and can effectively block the invasion of water and oxygen to the second display module 20, thereby improving the reliability of the tiled display panel 1000.
In some embodiments, the optical cement 107 has a light transmittance of greater than or equal to 90%. For example, in some embodiments, the light transmittance of the optical adhesive 107 may be any of 90%, 92%, 94%, 95%, 97%, 99%, or 100%. Since the transmittance of light of the optical cement 107 is greater than or equal to 90%, the light emitted from the LED chip 203 does not affect the display effect of the tiled display panel 1000.
In some embodiments, the Haze (Haze) of the optical adhesive 107 is less than 1%. The Yellowness Index (YI) is less than 1.
The Haze (Haze) is a percentage of the total transmitted light intensity that is 2.5 ° or more from the incident light, and a larger Haze means that the gloss and transparency of the package 30, particularly the imaging degree, are reduced. Haze is an important parameter of the optical transparency of transparent or translucent materials. The Yellowness Index (YI), also known as the yellow index, is used to characterize the degree to which a colorless transparent, translucent or nearly white polymeric material is yellowing. In the embodiment of the application, the high polymer material is used as the material of the optical cement 107, so that not only the light transmittance of the optical cement 107 can be ensured, but also the haze and the yellowness index of the optical cement 107 can be ensured, thereby improving the display effect of the spliced display panel 1000.
