Detailed Description
The following description of the various embodiments refers to the accompanying drawings that illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [ upper ], [ lower ], [ front ], [ rear ], [ left ], [ right ], [ inner ], [ outer ], [ side ], are only referring to the directions of the attached drawings. Accordingly, the directional terms used are used for explanation and understanding of the present invention, and are not used for limiting the present invention. In the drawings, elements having similar structures are denoted by the same reference numerals.
The invention provides a display device, which is used for solving the technical problem that the distance between the display device and a human body cannot be detected in the conventional display panel.
Fig. 1 is a schematic diagram illustrating a first structure of a display panel in the prior art, where the display panel is a conventional mobile phone screen. The display panel comprises a display area 10 and a non-display area 20, wherein the non-display area 20 is arranged around the display area 10 and is divided into an upper frame area, a lower frame area, a left frame area, a right frame area, a binding area and a driving IC (integrated circuit) to form the display device. The camera 21 and the distance sensor 22 are arranged in the upper frame area, the camera 21 is used for shooting, and the distance sensor 22 is used for sensing the distance between the mobile phone and a human body. When the distance between the mobile phone and the human body reaches a certain limit value, for example, when a call is answered, the mobile phone mainboard can control the display screen of the mobile phone to enter a screen-off state, and at the moment, the touch function of the display screen is also temporarily closed. Therefore, by providing the distance sensor, power consumption can be reduced and an erroneous operation caused by an erroneous touch can be prevented.
However, with the development of science and technology, people are pursuing higher display effect of the display panel, and the ratio of high resolution to high screen is becoming the trend of high-end mobile phones. In order to improve the screen occupation ratio, various large mobile phone manufacturers have proposed screens of different shapes, such as a "beauty tip", "bang screen", or a "water drop screen", which have the advantage of a smaller display area to be deducted compared with the conventional design in fig. 1.
However, the bang screen, the beauty tip screen and the water drop screen occupy a certain display area, and a new idea, namely, digging a hole in the surface is proposed in the industry at present. The in-plane hole digging is to dig a small hole in the middle of the display screen for placing a camera.
As shown in fig. 2, which is a schematic diagram of a second structure of a display panel in the prior art, the display panel includes a display area 10, an electronic component setting area 12 corresponding to a setting position of an electronic component, and a lower frame area 11, and holes are dug in the display area 10 of the display panel, and the electronic component is placed in the holes, so that an area of an upper frame is reduced, and a screen occupation ratio is improved. Because the existing in-plane hole digging design requires a small hole digging area, only a front-facing camera can be placed in the electronic component setting area 12, and no space is used for placing a distance sensor. However, when the distance sensor is not provided, if the face of the user of the mobile phone touches the mobile phone during a call, the user may cause misoperation, and when the mobile phone is in a pocket of clothes, the user is easy to cause various misoperation due to the wrong touch.
Therefore, the conventional display panel has a technical problem that the distance between the display panel and the human body cannot be detected, and needs to be improved.
As shown in fig. 3, the present invention provides a display device, which includes a display panel, a sensing circuit and a detection unit, wherein the display panel includes a display area 10 and an electronic component setting area 12 corresponding to a setting position of an electronic component; the sensing circuit is used for sensing the brightness of light entering the electronic element arrangement area 12 and converting the brightness into an electric signal; the detection unit is used for detecting the change of the electric signal so as to determine the distance between the display panel and a user.
The display panel is hollowed out in the display area 10 to form an electronic component placement area 12, and electronic components are placed in the electronic component placement area 12.
When the user uses the display device, the distance between the human body and the display panel is decreased, the light-entering brightness of the electronic component installation area 12 is decreased, the distance between the human body and the display panel is increased, and the light-entering brightness of the electronic component installation area 12 is increased.
The sensing circuit converts the brightness into an electrical signal, when the light entering brightness is weakened, the corresponding electrical signal is reduced, and when the light entering brightness is enhanced, the corresponding electrical signal is increased.
The detection unit detects a change in the current signal. When the electric signal is detected to be decreased, the distance between the human body and the display panel is decreased, the user may be in operation such as conversation, when the electric signal is detected to be increased, the distance between the human body and the display panel is increased, the user may already finish conversation, and the normal use state is entered.
According to the invention, by arranging the sensing circuit and the detection unit, the light incoming brightness change in the electronic element arrangement area can be judged according to the change of the electric signal, so that the distance between a human body and the display panel can be known, and the wrong touch screen and the wrong operation can be prevented.
As shown in fig. 3, the sensing circuit includes a photo-resistor 30, and the photo-resistor 30 is located in the electronic component mounting area 12. The photoresistor 30 has a characteristic that the resistance value changes with the change of the intensity (brightness) of the external light, when the incident light intensity is high, the resistance of the photoresistor 30 is reduced, and when the incident light intensity is low, the brightness is low, the resistance of the photoresistor 30 is increased.

The display device further comprises a flexible circuit board 50 and a main board connected with the flexible circuit board 50, the flexible circuit board 50 is bound with the binding area 11 of the display panel, the first end of the photosensitive resistor 30 is connected with the grounding end GND of the flexible circuit board 50 through a first connecting terminal, the second end of the photosensitive resistor 30 is connected with the main board through a second connecting terminal, and the photosensitive resistor 30, the main board and the grounding end GND form an induction circuit.
The flexible circuit board 50 is connected with one end of the chip on film 40, the other end of the chip on film 40 is provided with a binding terminal, when the flexible circuit board 50 is bound with the display panel, the binding terminal and the connecting terminal are aligned, and the binding terminal and the connecting terminal are connected by adopting anisotropic conductive adhesive, so that the flexible circuit board 50 is electrically connected with the display panel.
The other end of the flexible circuit board 50 is connected To a main board (not shown) via a BTB (board To board) connector 60, the BTB connector 60 being a board-To-board connector conventionally used for electrically connecting a pair of circuit boards parallel To each other.
Through the butt joint of the binding terminals and the connecting terminals, the electric connection between the main board and the flexible circuit board and the display panel is realized, and the signal transmission can be realized.
One end of the photo resistor 30 is connected to the first connection terminal, and then connected to the ground GND of the flexible circuit board 50 through the flip-chip film 40, and the other end is connected to the second connection terminal, and then connected to the motherboard through the flip-chip film 40, the flexible circuit board 50 and the BTB connector 60 in sequence.
As shown in fig. 4, an equivalent circuit diagram of the photo resistor is shown. The mainboard sends a fixed voltage signal to photo resistor 30, and when the human body was close display panel, the light inlet volume of digging the hole department became less, and photo resistor 30's resistance increases, and the electric current on the return circuit diminishes, keeps away from display panel when the human body, and the light inlet volume of digging the hole department increases, and photo resistor's resistance reduces, and the electric current grow on the return circuit. Therefore, the distance between the mobile phone and the human body can be detected by detecting the current of the loop, so that the function of the distance sensor designed by the traditional mobile phone is realized.

The active layer can be an amorphous silicon material, a polycrystalline silicon material or a metal oxide material, and the like, wherein when the active layer is made of a polycrystalline silicon material, the active layer can be formed by adopting a low-temperature amorphous silicon technology, that is, the amorphous silicon material is melted by the laser to form the polycrystalline silicon material.

A passivation layer 129 is disposed on the source electrode 127 and the drain electrode 128, and the passivation layer 129 may be silicon oxide (SiOx), silicon nitride (SiNx), or a sandwich structure of the two.
The film structure is not limited to this, and other structures, such as a bottom gate structure, may also be used.
There are many kinds of materials for the photo resistor 30, and the material of the photo resistor 30 may include cadmium sulfide, aluminum sulfide, lead sulfide, bismuth sulfide, or selenium, and may be a semiconductor material or a metal oxide. It may be disposed at different positions in the first substrate 100 according to the material.
In one embodiment, the photo-resistor 30 is disposed between the substrate 101 and the driver circuit layer 102. The photoresistor 30 and the active layer 121 may be disposed on the same layer, and at this time, the photoresistor 30 is made of a semiconductor material, and the photoresistor 30 and the active layer 121 may be manufactured in the same process.
In one embodiment, the photoresistor 30 is disposed in the driver circuit layer 102. The photo resistors 30 may be disposed in the same layer as the first metal layer 123, i.e., both formed on the first gate insulating layer 122, in the same layer as the second metal layer 125, i.e., both formed on the second gate insulating layer 124, and in the same layer as the source and drain layers, i.e., both formed on the interlayer dielectric layer 126. At this time, the photo-resistor 30 may be made of metal oxide, and the photo-resistor 30 and the film layer in the driving circuit layer 102 may be manufactured in the same process, and since the photo-resistor 30 is integrated in the manufacturing process of the first substrate 101, additional manufacturing of other components is not required, so that the process steps and the cost are reduced, and the manufacturing cost of the display panel is reduced.
In one embodiment, the photo-resistor 30 is disposed on a side of the driving circuit layer 102 away from the substrate 101. In this case, the material of the photoresistor 30 may be cadmium sulfide, aluminum sulfide, lead sulfide, bismuth sulfide, selenium, or the like, or may be a semiconductor material or a metal oxide.
Since the volume of the photo resistor 30 is small and cannot be seen by naked eyes, the screen occupation ratio of the display panel is not affected.
In addition, the sensing circuit of the present invention may also use other devices to sense the brightness of incoming light in the electronic component setting area and convert the brightness into a current signal. At the moment, the sensing circuit converts the light signals received by the solar cell into voltage signals, the detection unit can judge the light entering brightness change in the electronic element setting area by measuring the voltage changes at the two ends of the solar cell, and then the distance between a human body and the display panel is known, so that wrong touch screen and misoperation can be prevented.
In one embodiment, the display device further includes a touch panel, and the detection unit is configured to trigger the touch panel to stop touch when detecting that the electrical signal is smaller than or equal to a threshold value, and trigger the touch panel to resume touch when detecting that the electrical signal is greater than the threshold value.
The display panel of the invention can be an OLED display panel and can also be a liquid crystal display panel. When the display panel is an OLED display panel, the touch panel is disposed on the light emitting surface of the display panel. When the display panel is a liquid crystal display panel, In order to integrate the touch panel with the display panel, the touch function of the display device is usually realized by methods of "On-Cell" (On the Cell) and "In-Cell" (In the Cell), where the On-Cell means that the touch panel is embedded On the light emitting surface of the display panel, and the In-Cell means that the touch panel is embedded inside the display panel. The invention does not limit the type of the display panel and the relative position of the touch panel and the display panel.

By arranging the sensing circuit and the detection unit, when the electric signal is detected to be smaller than or equal to the threshold value, the fact that the distance between the human body and the display panel is smaller than or equal to the threshold value is shown, at the moment, the detection unit triggers the touch panel to stop touch, and misoperation cannot occur. When the electric signal is detected to be larger than the threshold value, the distance between the human body and the display panel is also larger than the threshold value, at the moment, the touch panel is triggered to recover touch, and the touch panel is in a normal working state.
In one embodiment, the detection unit is further configured to trigger the display panel to stop displaying the picture when the detection result indicates that the electrical signal is smaller than or equal to the threshold value, and trigger the display panel to display the picture when the detection result indicates that the electrical signal is greater than the threshold value.
The conventional display panel always keeps a display state during working, but when a call is made, the display panel does not need to display a picture, so that the waste of electric quantity is caused.
By arranging the sensing circuit and the detection unit, when the electric signal is detected to be smaller than or equal to the threshold value, the distance between the human body and the display panel is also smaller than or equal to the threshold value, and a user does not need to watch the display picture at the moment, so that the detection unit triggers the display panel to stop displaying the picture, namely, the display panel enters a screen-resting state, the power consumption of the display panel is reduced, and the endurance time of the display panel can be prolonged when the call time is longer. When the electric signal is detected to be larger than the threshold value, the distance between the human body and the display panel is also larger than the threshold value, and at the moment, the user is in a non-call stage and needs to watch the display picture, so that the display panel is triggered to display the picture for the user to watch.
