Electronic card
An electronic card including a substrate and a display panel is provided. The substrate has a first surface, a second surface opposite to the first surface, a first side, a second side opposite to the first side, a third side and a fourth side opposite to the third side, wherein the first surface and the second surface are surrounded by the first side, the second side, the third side and the fourth side. The display panel is disposed on the first surface and is roughly near the first side, the third side and the fourth side. Therefore, a disposition area of the display panel is wider.
1. An electronic card, comprising:
a substrate having a first surface, a second surface opposite to the first surface, a first side, a second side opposite to the first side, a third side and a fourth side opposite to the third side, wherein the first surface and the second surface are surrounded by the first side, the second side, the third side and the fourth side;
a display panel physically and directly disposed on the first surface and roughly near the first side, the third side and the fourth side;
a control unit physically and directly disposed on the second surface;
a button physically and directly disposed on the first surface and roughly near the second side;
a chip physically and directly disposed on the first surface and roughly disposed near the button for storage; and
a battery physically and directly disposed on the first surface and between the display panel and the chip,
wherein the display panel and an orthographic projection of the control unit on the substrate only partially overlap,
wherein the electronic card is a credit card or an access card,
wherein the display panel, the battery and the chip are disposed in sequence from the first side to the second side.
2. The electronic card as claimed in claim 1 , wherein the battery, the chip, the button and the orthographic projection of the control unit on the substrate do not overlap.
3. An electronic card comprising:
a substrate having a first surface, a second surface opposite to the first surface, a first side, a second side opposite to the first side, a third side and a fourth side opposite to the third side, wherein the first surface and the second surface are surrounded by the first side, the second side, the third side and the fourth side;
a display panel physically and directly disposed on the first surface and roughly near the first to the fourth sides; and
a control unit, a battery, a button and a chip, all physically and directly disposed on the second surface,
wherein the electronic card is a credit card or an access card,
wherein the button, the control unit, the battery and the chip are disposed in sequence from the first side to the second side, and orthographic projections of the button, the control unit, the battery and the chip all on the substrate completely overlap with the display panel.
4. The electronic card as claimed in claim 3 , further comprising:
a battery slot physically and directly formed on the second surface, and configured to dispose the battery.
