Abstract
The invention relates to a display which is suitable for being connected with a connector and comprises a backlight unit, a storage unit, a port, a transmission controller and a control unit. The port is capable of connecting to the connector and receiving a power source from the connector. The transmission controller can obtain a current value of the power source received by the port. The control unit transmits a current value request to the transmission controller. When the transmission controller receives the current value request, the transmission controller transmits the current value to the control unit. When the control unit judges that the current value is not lower than a current threshold value, the control unit controls the backlight unit to emit light according to a common brightness set value. When the control unit judges that the current value is lower than the current threshold value, the control unit controls the backlight unit to emit light according to a low-brightness set value.

Detailed description of the invention
Now in conjunction with attached drawing, the present invention is further elaborated:
Fig. 1 is a hardware annexation schematic diagram of an embodiment of inventive display；
Fig. 2 is a flow chart of the embodiment, illustrates the control method of the display.
Wherein, 100- display, 1- back light unit, 2- storage element, the port 3-, 4- transmission control unit (TCU), 5- panel unit,
6- warning light, 7- control unit, 200- connector.
Specific embodiment
As shown in Fig. 1 or Fig. 2, an embodiment of inventive display 100 is adapted to attach to a connector 200, and wrap
Containing a back light unit 1, a storage element 2, Single port 3, a transmission control unit (TCU) 4, a panel unit 5, a warning light 6 and a control
Unit 7.
In the present embodiment, which is a USB Type-C connector.
The storage element 2 stores the general brightness setting set by user for being relevant to 1 brightness of back light unit
Value, the low-light level setting value that Ji Yifei is set by user.
The port 3 can be connected to the connector 200, and receive a power supply and a vision signal or one from the connector 200
Video-audio signal.In the present embodiment, 3 one port USB Type-C of port.
The transmission control unit (TCU) 4 is connected to the port 3, and can obtain the port 3 the received power supply a current value.?
In the present embodiment, which is a USB Type-C controller.
The panel unit 5 is irradiated by the back light unit 1, and can show the vision signal or the video-audio signal.The warning light 6
It is in the present embodiment a LED warning light 6.
The control unit 7 be connected to the back light unit 1, the storage element 2, the transmission control unit (TCU) 4, the panel unit 5 and
The warning light 6.
Refering to fig. 1 or Fig. 2, illustrate the process of the control method of the display 100 below.
Firstly, as in step s 01, which transmits a current value and requests to give the transmission control unit (TCU) 4.In this reality
It applies in example, transmits the current value when the control unit 7 detects the connector 200 connection above port 3 and request to give the transmission
Controller 4.
Then, such as step S02, when the transmission control unit (TCU) 4 receives current value request, the transmission control unit (TCU) 4 is by the electricity
Flow valuve sends the control unit 7 to.
Then, such as step S03, when the control unit 7 receives the current value, which judges that the current value is
It is no to be lower than an electric current threshold value, if it is not, S04 is thened follow the steps, if so, thening follow the steps S05.
Step S04 is when the control unit 7 judges the current value not less than an electric current threshold value, the control unit 7
It shines according to the general brightness set value calculation back light unit 1.
Step S05 is when the control unit 7 judges the current value lower than the electric current threshold value, 7 basis of control unit
The low-light level set value calculation back light unit 1 shines, and is relevant to the current value lower than this via the panel unit 5 display one
The OSD prompting message of electric current threshold value, and the current value is relevant to lower than the electric current threshold value via the warning light 6 output one
Prompt signal.Whereby, when the current value is enough lower than the electric current threshold value but also to make the back light unit 1 with the low-light level setting value
When shining, which makes the back light unit 1 with lower Intensity LEDs automatically, makes the display 100 can also be with low-power consumption
Mode normal operation.Furthermore when the current value lower than the electric current threshold value and is not enough to light the back light unit 1, but also foot
When so that the warning light 6 shining, which makes the warning light 6 export the prompt signal automatically, to prompt user's electric current
It is worth too low.
In the present embodiment, the power port 3 which can also receive mains-supplied comprising one, OSD prompt news
The content of breath is, for example, to prompt user that the display 100 is connected alternating current.
In conclusion inventive display 100 judges the current value lower than the electric current threshold by when the control unit 7
Value, the control unit 7 shine according to the low-light level set value calculation back light unit 1, make the display 100 in the current value
Also have an opportunity when relatively low with the mode normal operation of low-power consumption, therefore the purpose of the present invention can be reached really.
The above description is only an embodiment of the present invention, and this does not limit the scope of protection of the present invention, it is all according to
Simple equivalent replacement or equivalence changes and modification made by scope of the present invention patent and patent specification content still belong to this
In the protection scope that patent of invention covers.
