Abstract
The utility model discloses a display screen with a distance sensing device. The display screen relates to the technical field of the display screen and comprises a bottom shell, a face frame, the display screen, a backlight and a backlight circuit; an outer shell consists of the bottom shell and the face frame; the display screen is arranged on the face frame; and the backlight is arranged in the outer shell and is electrically connected with the backlight circuit. The display screen with the distance sensing device further comprises the distance sensing device which is arranged on the face frame and is connected with the signal of the backlight circuit. The display screen with the distance sensing device has the beneficial effects that a distance sensor is arranged on the face frame of the display screen; when a mobile phone is in a call state, the display screen is close to the face of human body, the distance sensor transmits the signal to the backlight circuit when inducing that the display screen is close to the face of the human body, the backlight circuit cuts off a circuit switch to turn off the backlight, therefore, the backlight of the display screen of the mobile phone is in a close state on the phone, and a mass of electric energy is saved.
Description
Technical field
The utility model relates to display screen, relates in particular to the display screen of band distance sensing device.
Background technology
At present, the opening and closing of mobile phone screen backlight are controlled by function button, like this, when conversing, mobile phone screen is nearer from people's face, but mobile phone when being in talking state its backlight generally open, be very power consumption when the air time is long, secondly, in the time of conversation backlight to be in opening also bigger to the radiation of human face; In addition,, when mobile phone being packed into pocket or handbag, cause mistake easily, so also will cause a large amount of electric energy that consume mobile phone by the control button by the backlight of function button control display screen.
The utility model content
It is not to close in real time and open by mistake a kind of display screen that causes waste of energy to provide is provided that the purpose of this utility model is to overcome in the prior art by cause backlight by key control mobile phone display screen backlight.
The utility model is achieved through the following technical solutions: a kind of display screen with distance sensing device, comprise drain pan, face frame, display screen, backlight and backlight circuit, described drain pan and described frame are formed shell, described display screen is arranged at described frame, described backlight is arranged in the described shell and with the backlight circuit and is electrically connected, the utility model also comprises distance-sensor, and described distance-sensor is arranged at the face frame, and distance-sensor is connected with described backlight circuit signal.
The beneficial effects of the utility model are: the display screen of the utility model structure is provided with a distance-sensor on the face frame of display screen, distance-sensor is connected with the backlight circuit signal, when mobile phone is in talking state, display screen is pressed close to human body face, distance-sensor is sensed with the distance of human body face very near the time signal is passed to the backlight circuit, the backlight circuit is closed circuit disconnect switch with backlight, the backlight of mobile phone display screen promptly is in closed condition in conversation like this, has saved a large amount of electric energy; In addition, compared with prior art, be by backlight in the prior art by the key control mobile phone, cause mistake by the control button when mobile phone being packed into pocket or handbag easily, backlight by opening, so also will be caused a large amount of electric energy that consume mobile phone by mistake, but the utility model is controlled by distance perspective reply backlight, pocket and handbag all with the human body close together, can not cause the mobile phone backlight to open by mistake and open this situation, guaranteed that the mobile phone electric energy is not wasted.
Description of drawings
Fig. 1 is a block flowsheet schematic diagram of the present utility model.
Among the figure: 1, backlight; 2, backlight circuit; 3, distance-sensor.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
With reference to shown in Figure 1, display screen of the present utility model comprises drain pan, face frame, display screen, backlight 1 and backlight circuit 2, drain pan and described frame are formed shell, display screen is arranged on the face frame, backlight 1 is arranged in the shell and with backlight circuit 2 and is electrically connected, the utility model also comprises distance-sensor 3, and distance-sensor 3 is arranged at the face frame, and distance-sensor 3 is connected with backlight circuit 2 signals.The display screen of the utility model structure is provided with a distance-sensor 3 on the face frame of display screen, distance-sensor 3 is connected with backlight circuit 2 signals, when mobile phone is in talking state, display screen is pressed close to human body face, distance-sensor 3 is sensed with the distance of human body face very near the time signal is passed to backlight circuit 2, backlight circuit 2 is closed circuit disconnect switch with backlight 1, the backlight 1 of mobile phone display screen promptly is in closed condition in conversation like this, has saved a large amount of electric energy; In addition, compared with prior art, be by backlight 1 in the prior art by the key control mobile phone, cause mistake by the control button when mobile phone being packed into pocket or handbag easily, backlight 1 by opening, so also will be caused a large amount of electric energy that consume mobile phone by mistake, but the utility model is controlled by distance perspective reply backlight 1, pocket and handbag all with the human body close together, can not cause mobile phone backlight 1 to open by mistake and open this situation, guaranteed that the mobile phone electric energy is not wasted.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not constitute any restriction to the utility model just for convenience of description.
