## Abstract

A display system includes a display panel and an electrophoretic touch panel. The electrophoretic touch panel is optionally coupled to or separated from the display panel. When the electrophoretic touch panel is coupled to the display panel, the electrophoretic touch panel displays an input interface for inputting a signal to the display panel.

## Claims

### Claim 1

A display system, comprising:
a display panel; and
an electrophoretic touch panel, optionally coupled to or separated from the display panel;
wherein when the electrophoretic touch panel is coupled to the display panel, the electrophoretic touch panel displays an input interface for inputting a signal to the display panel.

### Claim 2 (depends on 1)

The display system of claim 1, wherein the display panel comprises a first connection member, and the electrophoretic touch panel comprises a second connection member, and connecting the first connection member to the second connection member connects the display panel to the electrophoretic touch panel.

### Claim 3 (depends on 1)

The display system of claim 1, wherein the display panel comprises a first signal interface, and the electrophoretic touch panel comprises a second connection member, the electrophoretic touch panel is electrically connected to the display panel through coupling the first signal interface to the second signal interface, to transmit the signal.

### Claim 4 (depends on 1)

The display system of claim 1, wherein the display panel comprises a first wireless communication unit, and the electrophoretic touch panel comprises a second wireless communication unit, the electrophoretic touch panel is electrically connected to the display panel through wirelessly coupling of the first wireless communication unit to the second wireless communication unit, to transmit the signal.

### Claim 5 (depends on 4)

The display system of claim 4, wherein the first wireless communication unit and the second wireless communication unit conform to a wireless fidelity (WiFi) specification.

### Claim 6 (depends on 1)

The display system of claim 1, wherein the input interface is a virtual keyboard, a virtual indicator input device or a virtual mouse.

### Claim 7 (depends on 1)

The display system of claim 1, wherein the display panel is an electrophoretic display panel, a liquid crystal display (LCD) or an active matrix organic light emitting diode (AMOLED) display.

### Claim 8 (depends on 1)

The display system of claim 1, wherein when the electrophoretic touch panel is electrically disconnected from the display panel, the electrophoretic touch panel displays an electronic reader interface or a hand-writing panel interface.

### Claim 9 (depends on 1)

The display system of claim 1, further comprising a touch pen for performing touch to the electrophoretic touch panel and the display panel.

### Claim 10 (depends on 9)

The display system of claim 9, further comprising a fixing mechanism for accommodating the touch pen.
