It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The electronic device and the display screen state determining method provided by the embodiment of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present application, and as shown in fig. 1, the electronic device includes: the display screen comprises a display screen 10 and an infrared module, wherein the infrared module is arranged towards the display screen 10;

under the condition that the display screen 10 is in a bright screen state, the infrared module works in a first waveband; under the condition that the display screen 10 is in a screen-off state, the infrared module works in a second wave band; the first band is larger than the second band.

The working principle of the embodiment of the application can be referred to as the following expression:

in the course of the applicant's practice, the following problems were found: the long-time irradiation of the infrared light that infrared module sent can influence the reliability and the life of light sensing element on display screen 10 on the display screen 10 to make organic material part and the light sensing element that display screen 10 includes produce permanent inefficacy when the electricity, influenced the life of display screen 10. The photosensitive element may be: a Thin Film Transistor (TFT) photosensitive element.

The reason for this is that: a TFT photosensitive element (mainly made of silicon material, a spectral response wavelength limit of a typical silicon photodiode is about 1100nm, a short wavelength limit is about 400nm, and a peak wavelength is about 900 nm), when infrared light (generally infrared light with a wavelength of 940nm) emitted by an infrared module is irradiated onto the TFT photosensitive element, the TFT is electrically sensitized, which causes a shift of a threshold voltage (Vth) and an increase of a leakage current, and under a long-time irradiation of the infrared light, an unrecoverable characteristic of the display screen 10 is permanently changed (i.e., the display screen 10 is not lighted, a characteristic of the TFT is changed, the display screen 10 is abnormal after the display screen 10 is lighted, or when the display screen 10 is lighted, the TFT generates a leakage current, and a capacitance charge storing a luminance signal is flowed out).

In the embodiment of the present application, under the condition that the display screen 10 is in the bright screen state, the infrared module operates in the first band; and under the condition that display screen 10 is in the state of disappearing the screen, infrared module work in the second wave band, and first wave band is greater than the second wave band, like this, can be different according to the state of display screen 10, control infrared module work in different wave bands, and above-mentioned different wave bands all can realize detecting function to reduce the harm that causes the reliability of the light sense component on the display screen 10, and then prolonged the life of the light sense component on the display screen 10.

Wherein, infrared module both can launch infrared light, also can receive infrared light, of course, can include the part of launching infrared light and the part of receiving infrared light in the infrared module, for example: as an alternative embodiment, the infrared module comprises an infrared emitter 20 and an infrared receiver 30. In this way, the infrared emitter 20 is used for emitting infrared light, and the infrared receiver 30 is used for receiving infrared light, so that the effect of distinguishing the emission of infrared light from the reception of infrared light is better, and the phenomenon that the emission and the reception of infrared light are mixed to cause a larger error of a detection result is avoided.

For example: in the case that the display screen 10 is in the bright screen state, the first infrared light of the first wavelength band may be emitted by the infrared emitter 20, and the infrared receiver 30 receives the first reflected infrared light to implement the distance detection; and under the condition that display screen 10 is in the state of disappearing the screen, can pass through the second infrared light of infrared transmitter 20 transmission second wave band, infrared receiver 30 receives the second reflection infrared light and realizes the distance detection, and first wave band is greater than the second wave band, like this, can be different according to the state of display screen 10, adopt the infrared light of different wave bands to realize infrared detection, thereby the harm that causes the reliability of the light sense component on the display screen 10 has been reduced, and then the life of the light sense component on the display screen 10 has been prolonged, correspondingly, the life of display screen 10 has also been prolonged. Meanwhile, infrared detection is realized by adopting infrared light of a second waveband, so that the detection sensitivity can be enhanced.

As an alternative embodiment, the infrared emitter 20 and the infrared receiver 30 may be packaged as an integrated structure, so that the connection strength and the fixing effect of the whole infrared module can be enhanced.

It should be noted that the first reflected infrared light may be infrared light that is transmitted out of the display screen 10, meets the external detection object 40, is reflected back into the display screen 10, and is received by the infrared receiver 30; similarly, the second reflected infrared light may be infrared light that is transmitted out of the display screen 10, meets the external test object 40, is reflected back into the display screen 10, and is received by the infrared receiver 30.

It should be noted that the first wavelength band is larger than the second wavelength band, and the first wavelength band may be referred to as a long wavelength band (for example, may be 1300nm), and the second wavelength band may be referred to as a middle wavelength band (for example, may be 940 nm). And based on the analysis and actual verification of the spectral response curve, the following results are obtained: when the display screen 10 is in a bright screen state (i.e., in a powered-on state), and the infrared emitter 20 emits infrared light of a middle waveband (e.g., 940nm), the infrared light has a large influence on the reliability of the display screen 10, that is, when the display screen 10 is in the bright screen state, the middle waveband (940nm) infrared light irradiates the display screen 10 for a long time, so that the organic material and the TFT photosensitive element of the screen 10 may permanently fail; when the display screen 10 is in the off-screen (i.e., powered-down) state, the reliability of the display screen 10 is negligibly affected by the mid-band infrared light. In addition, when the display screen 10 is in a bright screen (i.e., in a powered-up state) and the infrared emitter 20 emits infrared light of a long wavelength band (e.g., 1300nm), the infrared light has a small influence on the reliability of the display screen 10. Referring to fig. 2 and 3, the abscissa of fig. 2 and 3 represents the wavelength, and the ordinate represents the energy value.

In addition, the infrared receiver 30 may receive reflected infrared light, and may detect the intensity of the reflected infrared light. Of course, the infrared receiver 30 may only receive the emitted infrared light and send the detection result to the processor of the electronic device, and the processor finally obtains the distance value between the external object to be detected and the electronic device according to the detection result.

It should be noted that, because the electronic device can implement distance detection through the first reflected infrared light corresponding to the first infrared light of the first wavelength band and the second reflected infrared light corresponding to the second infrared light of the second wavelength band, as an optional implementation manner, the electronic device can implement approach detection through the first reflected infrared light corresponding to the first infrared light of the first wavelength band, and the electronic device can implement distance detection through the second reflected infrared light corresponding to the second infrared light of the second wavelength band.

For example: when the display screen 10 is in a bright screen state and the intensity of the first reflected infrared light is detected to be greater than a first preset threshold value, it can be shown that the external object to be detected 40 is closer to the electronic device at this time, and in order to prevent the object to be detected from being touched by mistake, the state of the display screen 10 can be adjusted to a screen-off state at this time; similarly, when the display screen 10 is in the off-screen state and the intensity of the second reflected infrared light is detected to be less than or equal to the second preset threshold, it can be shown that the external object to be detected 40 is far away from the electronic device, and the state of the display screen 10 can be adjusted to the on-screen state.

As an alternative embodiment, the infrared emitter 20 includes a first infrared emitter for emitting infrared light corresponding to the first wavelength band and a second infrared emitter for emitting infrared light corresponding to the second wavelength band.

Like this, owing to be provided with the first infrared emitter that is used for the infrared light that the transmission first wave band corresponds to and be used for the second infrared emitter that the infrared light that the transmission second wave band corresponds, thereby make the emission effect to the infrared light that the first wave band corresponds and the infrared light that the second wave band corresponds better, reduce the appearance of the infrared light that the first wave band corresponds and the infrared light that the second wave band corresponds mutual interference's phenomenon.

In addition, in the present embodiment, the infrared receiver 30 may receive the reflected infrared light corresponding to the first wavelength band and the reflected infrared light corresponding to the second wavelength band. Of course, the infrared receiver 30 may also include a first receiving component for receiving reflected infrared light corresponding to a first wavelength band, and a second receiving component for receiving reflected infrared light corresponding to a second wavelength band. The specific manner is not limited herein.

Namely: the electronic equipment can simultaneously comprise a first infrared transmitter, a second infrared transmitter, a first infrared receiver and a second infrared receiver; alternatively, the electronic device may only include the first infrared emitter and the second infrared emitter; or, the electronic device only comprises: a first infrared receiver and a second infrared receiver.
