detailed description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

The terms "first", "second" and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in sequences other than those illustrated or described herein, and distinguish between "first", "second", etc. The objects are usually of one type, and the number of objects is not limited. For example, the first object may be one or more than one. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

The electronic device and the display screen state determination method provided by the embodiments of the present application will be 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 provided by an embodiment of the application. As shown in FIG. 1 , the electronic device includes: a display screen 10 and an infrared module, and the infrared module faces the display screen 10 set up;

Wherein, when the display screen 10 is in the bright screen state, the infrared module works in the first band; when the display screen 10 is in the off-screen state, the infrared module works in the second waveband band; the first band is greater than the second band.

Wherein, the working principle of the embodiment of the present application may refer to the following expressions:

In the process of practice, the applicant found the following problems: the infrared light emitted by the infrared module irradiates on the display screen 10 for a long time, which will affect the reliability and service life of the photosensitive elements on the display screen 10, so that the The organic material part and the photosensitive element permanently fail when powered on, which affects the service life of the display screen 10 . The above-mentioned photosensitive element may be: a thin film field effect transistor (Thin Film Transistor, TFT) photosensitive element.

The reason is: TFT photosensitive element (mainly made of silicon material, typical silicon photodiode spectral response has a long wavelength limit of about 1100nm, a short wavelength limit of about 400nm, and a peak wavelength of about 900nm), when the infrared module emits After infrared light (generally using infrared light with a wavelength of 940 nm) is irradiated on the TFT photosensitive element, the inductance light on the TFT will cause the threshold voltage (Vth) to shift and the leakage current to increase. Under the long-term irradiation of infrared light , will cause the irreversible characteristics of the display screen 10 to change permanently (that is, if the display screen 10 is not lit, the TFT characteristics change, the display screen 10 is abnormal after the display screen 10 is turned on; or when the display screen 10 is illuminated, the TFT produces leakage current, the capacitor charge that stores the luminance signal is drained).

In the embodiment of the present application, when the display screen 10 is in the bright screen state, the infrared module works in the first band; and when the display screen 10 is in the off-screen state, the infrared module works in the second band, and The first waveband is larger than the second waveband, so that the infrared module can be controlled to work in different wavebands according to the different states of the display screen 10 , and the above-mentioned different wavebands can all realize the detection function, thereby reducing the light perception on the display screen 10 The reliability of the components is damaged, thereby prolonging the service life of the photosensitive components on the display screen 10 .

The infrared module can either emit infrared light or receive infrared light. Of course, the infrared module can include components that emit infrared light and components that receive infrared light. For example, as an optional implementation, the The infrared module includes an infrared transmitter 20 and an infrared receiver 30 . In this way, the infrared transmitter 20 is used for emitting infrared light, and the infrared receiver 30 is used for receiving infrared light, so that the difference between the emission of infrared light and the reception of infrared light can be better, and the confusion of emission and reception of infrared light can be avoided. The occurrence of a phenomenon that causes a large error in the detection results.

For example, when the display screen 10 is in the bright screen state, the infrared transmitter 20 can transmit the first infrared light of the first band, and the infrared receiver 30 can receive the first reflected infrared light to realize distance detection; In the case of the screen off state, the infrared transmitter 20 can transmit the second infrared light of the second wavelength band, and the infrared receiver 30 can receive the second reflected infrared light to realize distance detection, and the first wavelength band is greater than the second wavelength band. According to the different states of the display screen 10 , infrared light of different wavelength bands is used to realize infrared detection, thereby reducing the damage to the reliability of the photosensitive element on the display screen 10 and prolonging the reliability of the photosensitive element on the display screen 10 . The service life, correspondingly, also prolongs the service life of the display screen 10 . At the same time, the infrared detection is realized by using the infrared light of the second band, which can enhance the detection sensitivity.

Wherein, as an optional implementation manner, the infrared transmitter 20 and the infrared receiver 30 can be packaged into an integral molding structure, so that the connection strength and fixing effect of the entire infrared module can be enhanced.

It should be noted that the first reflected infrared light can be the infrared light that is transmitted out of the display screen 10 by the first infrared light, meets the external detection object 40 and then is reflected back into the display screen 10 and is received by the infrared receiver 30; the same In principle, the second reflected infrared light may be the infrared light that the second infrared light transmits out of the display screen 10 , encounters the external detection object 40 , then is reflected back into the display screen 10 , and is received by the infrared receiver 30 .

It should be noted that the first waveband is greater than the second waveband, and the first waveband may be referred to as a long waveband (eg, 1300 nm), and the second waveband may be referred to as a medium waveband (eg, 940nm). Based on the analysis of the spectral response curve and the actual verification, it can be known that when the display screen 10 is on the screen (that is, in the power-on state), and the infrared transmitter 20 emits infrared light in the middle band (for example, 940 nm), the infrared light affects the display screen. The reliability of the display screen 10 has a great influence, that is, when the display screen 10 is in the bright screen state, when the mid-band (940nm) infrared light is irradiated on the display screen 10 for a long time, the organic materials and TFT photosensitive elements of the screen itself of the display screen 10 will be damaged. A permanent failure will occur; and when the display screen 10 is in the off-screen (ie, power-off) state, the influence of the mid-band infrared light on the reliability of the display screen 10 is negligible. In addition, when the display screen 10 is bright (ie, powered on), and the infrared emitter 20 emits long-wavelength (eg, 1300 nm) infrared light, the infrared light has little effect on the reliability of the display screen 10 . Referring to FIG. 2 and FIG. 3 , the abscissas of FIG. 2 and FIG. 3 both represent wavelengths, and the ordinates represent energy values.

In addition, the infrared receiver 30 can receive the reflected infrared light, and can detect the intensity of the reflected infrared light. Of course, the infrared receiver 30 can also only receive and emit 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, since the electronic device can realize distance detection through the first reflected infrared light corresponding to the first infrared light in the first wavelength band and the second reflected infrared light corresponding to the second infrared light in the second wavelength band, then As an optional implementation manner, the electronic device can implement proximity detection through the first reflected infrared light corresponding to the first infrared light in the first band, and the electronic device can detect the proximity through the second reflected infrared light corresponding to the second infrared light in the second band Light enables remote detection.

For example: when the display screen 10 is in the bright screen state, and the intensity of the first reflected infrared light is detected to be greater than the first preset threshold, it can indicate that the external object to be detected 40 is close to the electronic device at this time. At this time, the state of the display screen 10 can be adjusted to the off-screen state; 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 explained that At this time, the external object to be detected 40 is far away from the electronic device, and at this time, the state of the display screen 10 can be adjusted to a bright screen state.

As an optional implementation manner, the infrared transmitter 20 includes a first infrared transmitter for emitting infrared light corresponding to the first wavelength band and a second infrared transmitter for emitting infrared light corresponding to the second wavelength band Infrared transmitter.

In this way, since the first infrared transmitter for emitting infrared light corresponding to the first wavelength band and the second infrared transmitter for emitting infrared light corresponding to the second wavelength band are provided, the infrared light corresponding to the first wavelength band and the infrared light corresponding to the first wavelength band are provided with The infrared light corresponding to the second wavelength band has a better emission effect, and the phenomenon of mutual interference between the infrared light corresponding to the first wavelength band and the infrared light corresponding to the second wavelength band is reduced.

In addition, on the basis of this embodiment, the infrared receiver 30 can receive reflected infrared light corresponding to the first wavelength band and 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 the first wavelength band, and a second receiving component for reflecting infrared light corresponding to the second wavelength band. The specific method is not limited here.

As another optional implementation manner, the infrared receiver 30 includes a first infrared receiver for receiving reflected infrared light corresponding to the first wavelength band and a first infrared receiver for receiving reflected infrared light corresponding to the second wavelength band the second infrared receiver.

In this way, since the first infrared receiver for receiving the infrared light corresponding to the first wavelength band and the second receiving transmitter for receiving the infrared light corresponding to the second wavelength band are provided, the infrared light corresponding to the first wavelength band can be better distinguished. The light and the infrared light corresponding to the second wavelength band reduce the mutual interference of the above two kinds of infrared light, resulting in the occurrence of the phenomenon that the detection result has a large error.

It should be noted that, the above two embodiments may be implemented simultaneously, or only one of them may be implemented. That is, the electronic device may include the first infrared transmitter, the second infrared transmitter, the first infrared receiver and the second infrared receiver at the same time; alternatively, the electronic device may only include the first infrared transmitter and the second infrared transmitter The transmitter; or, the electronic device only includes: the first infrared receiver and the second infrared receiver.
