To improve the fun of use.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention.

Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIGS. 1 and 2, a first preferred embodiment of the display system 100 of the present invention includes a remote control device 2, a display device 3, and a prompting unit 4.

The remote control device 2 includes a plurality of buttons 21, a control unit 22 and a first transmission unit 23. The plurality of buttons 21 are classified into a function button group 211, a digital button group 212, and a direction button group 213 according to their uses, and each button 21 generates a function signal S1 after being pressed. The control unit 22 is electrically connected to the button 21 to receive the function signal S1 and thereby obtain a control signal S2. The first transmission unit 21 is electrically connected to the control unit 22 to receive the control signal S2 and transmit it out.

The display device 3 of the present embodiment is a multi-functional, multi-option television such as a smart TV or a network protocol television having a networking function, and is used together with the remote control device 2, and includes a first The second transmission unit 31, a central processing unit 32, and a screen 33 electrically connecting the central processing unit 32 and the prompting unit 4, respectively. The central unit 32 receives the control signal S2 through the second transmission unit 31, and causes the display device 3 to be in one of a plurality of functional modes, and generates a command signal S3 according to its functional mode. The multiple functional modes described in this embodiment include a play cable, an HDMI (HIGH DEFINITION MULTIMEDIA INTERFACES, HDMI) signal source, and an AV (audio/visual) signal source function mode.

The prompting unit 4 is disposed in the display device 3, and is electrically connected to the display device 3 to receive the command signal S3, and accordingly obtains a prompt signal S4 indicating the button 21 operable in the functional mode. Further, the prompt signal S4 is a direct screen display (OSD) signal including a remote control icon 20, and is displayed after being received by the display device 3, wherein the operable button map in the remote control icon 20 The indication 201 is in a conspicuous format, and the remaining button icons 201' are comparatively non-obtrusive formats.

For practical examples, when the display device 3 is powered on and preset to the cable television function mode, the screen 33 displays the remote control icon 20 in an OSD manner for a predetermined period of time, for example, 5 seconds. Moreover, the remote control icon 20 displays a button icon that can be activated in this function mode through a bold format - mainly an up and down selection key to assist the user in distinguishing the valid or invalid button 21 . When the display device 3 is in the function mode of playing the cable TV, and the user accidentally touches the button 21 representing the HDMI, the display device 3 enters the function mode of playing the HDMI signal source (as shown in the upper right corner of FIG. 2), and its screen 33 displays the remote control icon 20 in the OSD mode for a predetermined time. At this time, the remote control icon 20 displays the button icons 201, 201' and the up and down selection keys that can be activated in this function mode in a bold format to assist the user in distinguishing the valid or invalid buttons 21, thereby reducing the user's groping keys. The time provided by the function of 21 makes it easier to operate the remote control device 2 to return the display device 3 to the functional mode of playing the cable television. It is further explained that when the screen 33 of the display device 3 displays the remote control icon 20 in the OSD manner, the button icon 201 ′ representing the invalid button 21 in the remote control icon 20 can also be cancelled, thereby guiding the use. The operator operates correctly to improve the convenience of use.

Referring to FIG. 3 and FIG. 4, the difference between the second preferred embodiment of the present invention and the first preferred embodiment is that the prompting unit 4 of the present embodiment is disposed in the remote control device 2 and electrically connected to the control unit 22, respectively. And a button 21, and includes a plurality of backlight modules (not shown) disposed under the button 21. Referring to FIG. 3 and FIG. 5, the prompt signal S4 controls the backlight module under the operable button 21' to emit light, and each backlight module has a first light source and a second light source of different colors, and the prompt signal S4 can be controlled. The first light source of the backlight module under the operated button 21' emits light, and the second light source that controls the backlight module under the remaining buttons 21" emits light. In this embodiment, the first light source emits green light, and the second light source emits red light. It means that the operation and the inoperability are respectively illustrated.

In this embodiment, when the user accidentally touches the button 21 representing the HDMI, the backlight module under the remote control device 2 activates the first light source to emit green light to illuminate the operable button 21', and the second light source emits red light. The remaining buttons 21" are effective to prompt the user to display the green light button 21, thereby assisting the user in quickly learning and reducing the invalid operation of the remote control device 2.

Another variation of this embodiment is that when the user accidentally touches the button 21 representing the HDMI, the backlight module under the remote control device 2 activates a light source to illuminate the operable button 21', and the remaining buttons 21" are not illuminated. The button 21, which is illuminated to prompt the user to display the light source, is also effective, and can also assist the user in reducing the invalid operation of the remote control device 2.

In summary, the prompting unit 4 provides the user with a quick identification of the valid or invalid button 21, so that the user can quickly enter the function mode to be played by the prompting of the prompting unit 4, creating a new remote control device 2 The operational experience, indeed, can achieve the object of the present invention.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
