[0013] The invention will be more fully understood from the following detailed description and drawings, which are used for illustrative purposes only and do not limit the scope of protection of the invention.

[0014] The present invention will become more apparent from the following detailed description, which is made with reference to the drawings in which like reference numerals correspond to like elements.

[0015] 1, the electronic device 1 includes a substrate 10 and a plurality of element units 30. The substrate 10 defines a plurality of edges 10E and functional areas 20, and the plurality of element units 30 are disposed within the functional areas 20.

[0016] As shown in FIGS. 2 and 3, each element unit 30 includes one or more functional elements 31 and a driving circuit 32. The one or more functional elements 31 define the geometric center G31 of the element in FIG. 3, and multiple functional elements 31 (not shown) can jointly define the geometric center of the element. The driving circuit 32 defines the geometric center G32 of the circuit and further includes multiple transistors 321, as shown in the circuit diagram of FIG. 4. These transistors 321 are composed of semiconductor material patterns 322, which form the geometric center G32 of the circuit. Taking a display device as an example, the layout of the element unit 30, functional elements 31, and driving circuit 32 is shown in FIGS. 5A and 5B. In FIGS. 5A and 5B, one pixel of the display device is considered to be the element unit 30, and a light-emitting diode (LED) is considered to be the functional element 31 of the present invention. The driving circuit 32 includes transistors T1 and T2 and is composed of semiconductor material patterns 322. The pixel includes an electric capacitance Cst (for example, a storage capacitance) and wiring such as a data line, a scanning line, AVDD, and AVSS.

[0017] As shown in FIG. 3, in one element unit 30 near the edge 10E of the substrate, the geometric center G32 of the circuit is located on one side of the geometric center G31 of the element, and is away from the corresponding edge 10E of the substrate.

[0018] In one embodiment, each element unit 30 is a pixel unit, the functional element 31 is an inorganic light emitting diode (LED) or an organic light emitting diode (OLED), and the electronic device is a display device.

[0019] In one embodiment, in a column or row of element units 30 in direction D1 of functional region 20 (or direction D2 in another embodiment), a distance g31 between the geometric center G31 of the element and the corresponding edge 10E, and a distance g32 between the geometric center G32 of the circuit and the corresponding edge 10E are defined. As shown in Figures 2 and 3, the distance g32 is greater than half the distance gp1 between the geometric centers G31 of any two adjacent elements in direction D1. Note that the distance gp1 between the geometric centers G31 of any two adjacent elements can be fixed, but is not limited to this.

[0020] In one embodiment, in a row or column of element units 30 in the direction D1 or D2 of the functional area 20, the distance gp2 between the geometric centers G32 of the two adjacent circuits between the two element units 30 furthest apart in the direction D1 of the functional area is greater than the distance gp1 between the geometric centers G31 of the two adjacent elements, as shown in Figure 1. In another embodiment, the geometric centers G32 of the two circuits are located between the geometric centers G31 of the two elements.

[0021] The distance gf32 between the geometric centers G32 of the circuits of the two most distant element units 30 is smaller than the distance gf31 between the geometric centers G31 of the elements of the two element units 30. In this embodiment, in the direction D1 of the functional region 20, as shown in Figure 3, the distance g32 is greater than half the distance gp1 between the geometric centers G31 of the two adjacent elements.

[0022] As shown in FIG. 6, the electronic device 100 is formed by joining multiple electronic devices 1. The electronic devices 1 are joined together by the edge 10E of the substrate 10. For example, the electronic devices 1 and 1' are connected to each other by the edges 10E and 10E'. In the functional areas of two adjacent electronic devices 1 and 1', the distance gt32 between the geometric centers G32 of the two circuits of the nearest adjacent element units 30 is greater than the distance gt31 between the geometric centers G31 of the two elements. In one embodiment, the electronic device 100 is formed by joining multiple display devices (electronic devices 1), and the functional elements 31 of the electronic devices 1 are light-emitting elements. The distance gt31 may be the same as the pixel distance of the display devices (electronic devices 1). In another embodiment, the distance gt31 is smaller than the distance gp1 of the electronic devices 1. Furthermore, the distance gt31 and the distance gp1 are smaller than the distance gt32.

Those skilled in the art will recognize various modifications to the disclosed embodiments and alternative embodiments that may be implemented. Accordingly, the appended claims encompass all modifications that fall within the scope of the disclosed invention. [Industrial Applicability]
