When any of the touch keys 121-128 on the touch panel 12 accepts touch, a first touch information is correspondingly transmitted to the processor 11, and the processor 11 The illumination module 13 is illuminated according to the first touch information to control the illumination module 13 to illuminate the touch panel 12 to make the touch panel 12 bright and visible, thereby allowing the user to conveniently operate the touch panel 12.

When the light-emitting module 13 illuminates the touch panel 12, the processor 11 starts a waiting time, and receives a second touch information at the waiting time, and the processor 11 transmits the corresponding information through the connection port 14 The control signal to the control circuit of the display causes the display to perform an action corresponding to the second touch information. When the processor 11 does not receive the second touch information after the waiting time is counted (ie, the waiting time), a shutdown signal is sent to control the lighting module 13 to be turned off to reduce power consumption. In the preferred embodiment, the waiting time is 2 to 5 seconds, preferably 3 seconds. The processor 11 controls the timing of the waiting time after the lighting module 13 is turned off.

When the display (not shown) does not receive the control signal for more than one idle time or does not have any signal source input, it enters a power saving mode.

After the display enters the power saving mode, the user slides a plurality of touch keys arranged adjacent to the touch panel 12 by hand, such as sliding touch keys 121-123, or touch keys 121-124, or touch. The touch panel 12 transmits the second touch information to the processor 11 , and the second touch information includes the touch generated by the plurality of touch keys, such as 121~125 or touch keys 127~124. The control unit 11 controls the illumination module 13 to illuminate the touch panel 12 according to the second touch information. The number of the most preferred touch keys is four or more.

When the processor 11 continues to receive the second touch information from the touch panel 12 for a first continuous time, the second touch information is a touch signal generated by the function disable button 128. The processor 11 sends a control signal to a control circuit (not shown) of the display (not shown) to set the display to be inoperable, so as to avoid when the display is to be cleaned (not shown) The display is accidentally touched; wherein the first continuous time is 2 to 5 seconds, preferably 3 seconds. In the preferred embodiment, the processor 11 will resume the timing of the first continuous time.

When the processor 11 continues to receive the second touch information from the touch panel 12 for a second continuous time, the second touch information is the menu button 124 and the mother screen display mode button. 126 generates a touch signal, and the processor 11 sets the touch panel 12 to prohibit operation. In the preferred embodiment, the processor 11 will resume the timing of the second continuous time.

According to the above configuration, the first touch information transmitted by the touch panel 12 is received by the processor 11, and the light-emitting module 13 is controlled to illuminate the touch panel 12 for the user to clearly recognize the touch. The touch keys on the board 12 are convenient for operating the display, thereby improving the convenience of use.

According to the foregoing, the method for prompting the display control device having the light source prompting function is further summarized. The processor 11 performs the following steps: the processor 11 determines whether the first touch information is received by the touch panel 12 (S11). If the processor 11 sends the control signal to control the illumination module 13 to illuminate the touch panel 12 (S12); the processor 11 determines whether the touch panel 12 is received during the waiting time. The second touch information (S13); if yes, the processor 11 sends a corresponding control signal to the control circuit of the display, so that the display performs an action corresponding to the second touch information (S14); if not, the The processor 11 sends a turn-off signal to control the light-emitting module 13 to be turned off (S15).

When the above step is performed to the step of "the processor 11 determines whether the touch panel 12 receives the first touch information (S11)", if not, the processor 11 re-determines whether the touch is received. The first touch information is transmitted from the board 12; thereby repeatedly detecting whether the first touch information is received.

Through the above steps, the processor 11 determines that the touch panel 12 transmits the first touch information, and controls the light-emitting module 13 to illuminate the touch panel 12 so that the user can clearly see the keys. The touch key on the touch panel 12 further operates the display by touching a corresponding touch key, thereby The user can easily operate the display in a dim environment to improve the convenience of use.
