Embodiment
Technical scheme provided by the invention is: by directly the source input state indicator light being set the position of perception at TV set panel or other users, the detecting signal unit of television set detects the source input state of its each road information source input port, and testing result is transferred to television set microcontroller MCU, MCU is according to the shutoff or the closure of the testing result control source input state indicator light circuit of detecting signal unit transmission, thereby the source input state indicator light carries out bright according to the situation of information source input or goes out, and the user is according to the bright of these source input state indicator lights or go out and judge whether its corresponding information source input port has signal input.
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In the embodiment of the invention, the information source indicator light is that example describes with the LED lamp, for the purpose of directly perceived, these LED lamps are arranged on the panel of television set, as position near the TV set power indicator light, (concrete being provided with can be according to the shape of television set to become the arrangement of horizontally-arranged or vertical setting of types, and consider apparent decorative effect), as shown in Figure 1, LED lamp next door is provided with the sign of its corresponding information source input port, as AV1, AV2 and USB etc., the user can understand the information source input port of each LED lamp representative by this sign.During the practical application technical solution of the present invention, the physical location of information source indicator light with the user can visual perception it is bright or go out and be as the criterion.
The TV Principles block diagram that the embodiment of the invention provided as shown in Figure 2, wherein, the input that information source input port is responsible for signal provides interface, and send television signal to handle and display module processs and displays at following signal of choosing of the control of MCU; Detecting signal unit is used for the information source input condition of each road information source input port is detected, detect each road information source input port whether the signal input is arranged, and send testing result to MCU and handle accordingly and control, concrete testing circuit and detection method are the technology that those of ordinary skills know, and this does not give unnecessary details; The remote control receiving element receives the signal from remote controller, and relevant order is transmitted a MCU operate accordingly and control; The OSD unit generates the OSD menu under the control of MCU, and coherent signal is sent to signal processing and display unit carries out overlap-add procedure and demonstration; MCU controls whole system, receives various information, and sends various operational orders; In the embodiment of the invention, the source input state indicating member comprises LED current supply circuit part and display control section, MCU is used for sending instruction according to the testing result of detecting signal unit transmission to display control section, display control section is according to the closed of the commands for controlling LED current supply circuit of MCU or disconnect, thus control LED lamp bright or go out.
The concrete structure of source input state indicating member and with the annexation of MCU as shown in Figure 3, wherein, the number of LED current supply circuit is corresponding with the number of television set information source input port, LED current supply circuit part correspondence also is provided with same number of LED lamp, is used for that each information source input interface is carried out signal and has or not indication.
Simultaneously, be provided with a K switch on each LED current supply circuit, this K switch is assigned to control by display control unit.That is, when display control section gave closed signal, K switch was closed immediately, and corresponding LED lamp current supply circuit is connected, and the LED lamp is lighted; When signal that display control section opens, K switch disconnects immediately, and corresponding LED lamp current supply circuit also is disconnected, and the LED lamp extinguishes immediately.
Be provided with K switch 1 in the LED loop as video inputs mouth AV1 correspondence, be provided with K switch 2 in the LED loop of video inputs mouth AV2 correspondence, be provided with K switch 3 in the LED loop of USB input port correspondence ....
For example, when television set AV1 port had signal input, other information source input port not to have the signal input, detecting signal unit detected each port at this moment had the information of no signal input to send MCU to.After MCU receives testing result, send instruction to the source input state indicating member, the display control section Closing Switch K1 in the indicatingjhe source input state indicating member, disconnect other K switch 2, K3 ....So display control section control switch K1 is closed, rest switch K2, K3 ... disconnect.So, LED1 is lighted, and other LED lamps extinguish.
When the user see that the LED1 lamp is bright, when other LED lamps extinguish, the LED lamp corresponding identification from the TV set panel as can be known, this moment, television set had only AV1 that the signal input is arranged, other ports do not have the signal input.
Thus, show the situation of television set information source input by utilizing the bright of LED lamp or going out, thereby for the user provides a kind of simple and clear method of indicatingjhe source input condition, thereby better operating experience brought for the user.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
