Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

In the related art, in order to improve the detection capability of the proximity sensor, the proximity sensor focuses and emits infrared rays to improve the energy of the infrared rays, so that the infrared rays are easily reflected back to the proximity sensor to be received by the proximity sensor after reaching an object outside the electronic device. However, since the energy of the focused infrared ray is high, the display pixels of the touch display screen are likely to generate electron migration, thereby generating a flicker phenomenon.

Referring to fig. 1 and fig. 2, an electronic device 100 is provided in an embodiment of the present disclosure. The electronic device 100 includes a housing 10, a touch display screen 20, and a proximity sensor 30.

The touch display screen 20 is provided in the housing 10. The touch display screen 20 includes a display layer 22 and a cover sheet 24 covering the display layer 22. A gap 11 is formed between the display layer 22 and the housing 10.

The proximity sensor 30 is arranged on the side of the gap 11 remote from the cover plate 24. The proximity sensor 30 includes a first emitter 32, a second emitter 34 and a receiver 36, the first emitter 32 is used for emitting first infrared rays to the outside of the electronic device 100 through the gap 11 and the cover plate 24, the second emitter 34 is used for emitting second infrared rays to the outside of the electronic device 100 through the display layer 22 and the cover plate 24, the receiver 36 is used for receiving the first infrared rays and the second infrared rays reflected by objects outside the electronic device 100, and the emission power of the first emitter 32 is greater than that of the second emitter 34, so that the second infrared rays do not cause the display layer 22 to flicker.

The electronic device 100 of the embodiment of the present application uses two emitters to emit infrared rays, and the first emitter 32 with higher power emits the first infrared rays from the gap 11 between the display layer 22 and the housing 10, and the second emitter 34 with lower power emits the second infrared rays through the display layer 22, and because the power of the second emitter 34 is lower, the energy of the second infrared rays emitted by the second emitter 34 is lower, and the display layer 22 will not flicker. In addition, the first emitter 32, the second emitter 34 and the receiver 36 cooperate to detect the distance between the object and the electronic device 100.

It should be noted that in the present embodiment, the proximity sensor 30 is disposed below the display layer 22, and implements an under-screen proximity scheme. In the present embodiment, the proximity sensor 30 is disposed below the display layer 22, which may mean that the proximity sensor 30 is disposed directly below the display layer 22, and in this case, the projection of the proximity sensor 30 on the plane where the display layer 22 is located is entirely located in the display layer 22; it may also mean that the proximity sensor 30 is disposed obliquely below the display layer 22, in which case the projection of the proximity sensor 30 onto the plane of the display layer 22 is located outside the display layer 22, or the projection of the proximity sensor 30 onto the plane of the display layer 22 is entirely located outside the display layer 22.

In one example, the first emitter 32 has a power of 5mW (milliwatts) and the second emitter 34 has a power of 3 mW. Because the emitting power of the second emitter 34 is smaller, the energy of the second infrared ray emitted by the second emitter 34 is smaller than the energy required by the electronic device of the display layer 22 to realize the electron migration, so that the phenomenon of the electron migration and the phenomenon of the flicker of the display layer 22 do not occur.

It should be noted, therefore, that the emission power of the second emitter 34 is less than the critical value of the power that causes the flicker phenomenon to occur in the display layer 22.

It can be understood that the first infrared ray emitted from the first emitter 32 has a longer range because the first emitter 32 has a larger emission power. In addition, since the first infrared ray is emitted from the gap 11 and the gap 11 is small, the first emitter 32 emits the first infrared ray at a predetermined emission angle, and thus the first infrared ray reflected by an external object farther from the cover plate 24 can be received by the receiver 36. That is, the first transmitter 32 in cooperation with the receiver 36 may detect a remote external object. For example, the first emitter 32 in cooperation with the receiver 36 may detect a foreign object that is greater than 1cm (centimeter) from the cover plate 24.

Since the second transmitter 34 has a smaller transmitting power, the second infrared ray emitted from the second transmitter 34 has a shorter range, and the second transmitter 34 and the receiver 36 cooperate to detect a distant external object. For example, the second transmitter 34 in cooperation with the receiver 36 may detect foreign objects less than or equal to 1cm (centimeter) from the cover plate 24.

In one embodiment, the width of the gap 11 is 1-2 mm. Thus, the width of the gap 11 can ensure that the first infrared rays emitted from the first emitter 32 can be emitted out of the electronic device 100 normally. In addition, the width of the gap 11 can also make the size of the black edge of the electronic device 100 smaller, so that the screen occupation ratio of the electronic device 100 can be improved. The black border size of the electronic device 100 is a size of the cover 24 side of the electronic device 100, and contents such as pictures cannot be displayed.

It should be noted that, when the gap 11 needs to be filled with an adhesive to adhere the touch display 20 and the housing 10, the adhesive filled in the gap 11 is a transparent adhesive, so as to ensure that the first infrared rays emitted by the first emitter 32 can be emitted out of the electronic device 100 through the adhesive.

By way of example, the electronic device 100 may be any of various types of computer system equipment (only one modality shown in FIG. 2 by way of example) that is mobile or portable and that performs wireless communications. Specifically, the electronic apparatus 100 may be a mobile phone or a smart phone (e.g., an iPhone (TM) based phone), a Portable game device (e.g., Nintendo DS (TM), PlayStation Portable (TM), game Advance (TM), iPhone (TM)), a laptop computer, a PDA, a Portable internet appliance, a music player and a data storage device, other handheld devices and a headset such as a watch, an in-ear headphone, a pendant, a headset, etc., and the electronic apparatus 100 may also be other wearable devices (e.g., a Headset (HMD) such as electronic glasses, electronic clothing, an electronic bracelet, an electronic necklace, an electronic tattoo, an electronic device, or a smart watch).

The electronic apparatus 100 may also be any of a number of electronic devices including, but not limited to, cellular phones, smart phones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, cameras, other media recorders, radios, medical devices, vehicle transportation equipment, calculators, programmable remote controllers, pagers, laptop computers, desktop computers, printers, netbook computers, Personal Digital Assistants (PDAs), Portable Multimedia Players (PMPs), moving Picture experts group (MPEG-1 or MPEG-2) Audio layer 3(MP3) players, portable medical devices, and digital cameras, and combinations thereof.

In some cases, electronic device 100 may perform multiple functions (e.g., playing music, displaying videos, storing pictures, and receiving and sending telephone calls). If desired, the electronic apparatus 100 may be a portable device such as a cellular telephone, media player, other handheld device, wrist watch device, pendant device, earpiece device, or other compact portable device.

Specifically, the housing 10 is an external component of the electronic device 100, and functions to protect internal components of the electronic device 100 such as the touch display screen 20. More specifically, the housing 10 may be a middle frame of the electronic device 100, which is used for mounting the touch display screen 20, a main board, and other components of the electronic device 100. The housing 10 may be formed by CNC machining of an aluminum alloy, or may be injection molded using Polycarbonate (PC) or PC + ABS material.

The display layer 22 is, for example, an OLED display screen. An Organic Light-Emitting Diode (OLED) display panel has good Light transmittance and can pass visible Light and infrared Light. Therefore, the OLED display screen does not affect the emission and reception of infrared rays by the proximity sensor 30 in the case of exhibiting the effect of contents. The display layer 22 may also be a Micro LED display screen, which also has good transmittance for visible light and infrared light. Of course, these display screens are merely exemplary and embodiments of the present application are not limited thereto.

The material of the cover plate 24 may be made of a light-transmitting material such as glass, ceramic, or sapphire. Since the cover plate 24 covers the display layer 22, the cover plate 24 may be made of a material having a relatively high hardness, such as the above sapphire material, in order to protect the display layer 22. Or a hardened layer may be formed on the surface of the cover plate 24 to improve the scratch resistance of the cover plate 24.

In addition, as shown in fig. 1, the electronic device 100 may include a processor 40, and the processor 40 is configured to control a display state of the touch display screen 20 according to an output signal of the proximity sensor 30.

Please note that, the embodiment of the present application takes the electronic device 100 as a mobile phone as an example for description. The mobile phone can prevent the misoperation of a user and is beneficial to saving the electric quantity of the mobile phone by arranging the proximity sensor 30 to determine the distance between the mobile phone and an external object and making corresponding adjustment. When the user is receiving or making a call and brings the mobile phone close to the head, the processor 40 generates detection information by calculating the time when the first emitter 32 and the second emitter 34 emit infrared rays and the receiver 36 receives the reflected infrared rays, and the processor 40 turns off the touch display screen 20 according to the detection information. When the mobile phone is far away from the head, the processor 40 turns on the touch display screen 20 again according to the detection information fed back by the proximity sensor 30.

Referring to fig. 2, in some embodiments, the housing 10 includes a substrate 12 and a sidewall 14 extending from an edge of the substrate 12, the sidewall 14 surrounds the touch screen 20, and the gap 11 is formed between the sidewall 14 and a side of the touch screen 20.

As such, the first emitter 32 emits the first infrared ray through the gap 11 between the sidewall 14 and the side of the touch display screen 20 to detect the distance between the external object and the electronic device 100.

In one embodiment, the substrate 12 and the sidewall 14 may be a unitary structure, for example, the substrate 12 and the sidewall 14 may be formed by in-mold injection. Of course, the base plate 12 and the side wall 14 may be formed as separate bodies, for example, after the base plate 12 and the side wall 14 are formed as separate bodies, the base plate 12 and the side wall 14 are connected together by welding, bonding, or screwing.

The proximity sensor 30 may be fixed on the substrate 12, and the proximity sensor 30 may be connected to a main board of the electronic device 100 through a flexible circuit board, so that the battery of the electronic device 100 may supply power to the proximity sensor 30 through the main board.

Referring to fig. 2, in some embodiments, the sidewall 14 is formed with a first recess 142 that communicates with the gap 11, and the first emitter 32 is partially disposed in the first recess 142.

In this manner, the sidewall 14 is hollowed out to form the first groove 142, and the first radiator 32 is partially located in the first groove 142, so that the first radiator 32 is more compactly fitted to the housing 10, thereby enabling the electronic device 100 to be more miniaturized.

Specifically, the shape of the first recess 142 and the shape of the first emitter 32 may be similar, for example, the first recess 142 and the first emitter 32 may both be oriented, so that the first emitter 32 and the first recess 142 may be more compactly fitted. It is understood that the size of the first recess 142 is slightly larger than the size of the first radiator 32 so that the first radiator 32 can be placed in the first recess 142.

In one example, as shown in fig. 3, the first emitter 32 emits a first infrared ray from the gap 11 of the top 1313 of the electronic device 100; as shown in fig. 4, the first emitter 32 emits the first infrared ray from the gap 11 of the side 1315 of the electronic device 100.

Of course, in other embodiments, the first emitter 32 emits the first infrared ray from the gap 11 at any position of the electronic device 100.

Since the receiver of the electronic device 100 is generally located on the top 1313 of the electronic device 100, the first emitter 32 preferably emits the first infrared ray from the gap 11 of the top 1313 of the electronic device 100. As such, proximity of the first transmitter 32 in cooperation with the receiver 36 may detect whether the electronic device 100 is near the user's head when the user answers a call, thereby further controlling the display state of the display layer 22.

Referring again to fig. 2, in some embodiments, a second recess 144 is formed at an end of the sidewall 14 away from the substrate 12, and an edge of the cover plate 24 is located in the second recess 144.

Thus, the end of the sidewall 14 away from the substrate 12 is the top end of the sidewall 14. The top end of the sidewall 14 is formed with a second groove 144 so that the top end of the sidewall 14 forms a stepped structure. The edge of the cover plate 24 can be supported in a step structure, which not only makes the side wall 14 and the cover plate 24 fit more compactly, but also makes the touch display screen 20 and the housing 10 connected more firmly, so as to improve the stability of the electronic device 100.

In some embodiments, the first emitter 32, the second emitter 34, and the receiver 36 are disposed apart from one another, as shown in FIG. 2.

In this manner, the first emitter 32, the second emitter 34 and the receiver 36 can be separately packaged and formed, which can reduce the overall volume of the proximity sensor 30, and also can facilitate the installation of the first emitter 32, the second emitter 34 and the receiver 36 to different locations, so that the assembly efficiency of the electronic device 100 can be improved. In addition, this is also advantageous in preventing the infrared rays emitted from the first emitter 32 and the second emitter from interfering with each other.

It should be noted that the distance between any two of the first emitter 32, the second emitter 34 and the receiver 36 can be specifically set according to practical situations, and is not limited in this application.

In some embodiments, the first emitter 32, the second emitter 34, and the receiver 36 are arranged in parallel. In this way, the receiver 36 can simultaneously receive the infrared rays emitted by the first emitter 32 and the second emitter 34 and reflected back by the external object, so as to ensure the normal operation of the proximity sensor 30. As shown in fig. 1, the first emitter 32, the second emitter 34, and the receiver 36 are juxtaposed along a common line.

The first emitter 32, the second emitter 34, and the receiver 36 may be juxtaposed along a lateral direction of the electronic device 100, or may be juxtaposed along a longitudinal direction of the electronic device 100. As shown in fig. 3, when the proximity sensor 30 is disposed on the top 1313 of the electronic device 100, the first emitter 32, the second emitter 34, and the receiver 36 are disposed along the longitudinal direction of the electronic device 100. As shown in fig. 4, when the proximity sensor 30 is disposed at the side 1315 of the electronic device 100, the first emitter 32, the second emitter 34, and the receiver 36 are disposed along a lateral direction of the electronic device 100.

Preferably, receiver 36 is located between first transmitter 32 and second transmitter 34.

Referring to FIG. 5, in some embodiments, a light blocking member 50 is disposed between the first emitter 32 and the receiver 36, and/or between the second emitter 34 and the receiver 36, and the light blocking member 50 abuts the touch display screen 20.

In other words, a light blocking element 50 is disposed between the first emitter 32 and the receiver 36, the light blocking element 50 abutting the touch display screen 20; alternatively, the first and second electrodes may be,

a light barrier element 50 is disposed between the second emitter 34 and the receiver 36, the light barrier element 50 abutting the touch display screen 20; alternatively, the first and second electrodes may be,

between the first emitter 32 and the receiver 36, and between the second emitter 34 and the receiver 36, there is disposed a light blocking element 50, the light blocking element 50 abutting the touch display screen 20.

In this way, the light blocking element 50 may block infrared rays emitted by the first emitter 32 and/or the second emitter 34 from being directly received by the receiver 36 before being emitted out of the electronic device 100, so that the proximity sensor 30 cannot accurately determine the distance between an object outside the electronic device 100 and the electronic device 100, and the normal operation of the proximity sensor 30 is affected.

Specifically, the light blocking member 50 may be made of non-light-transmitting material such as foam, plastic, etc., so that infrared rays can be blocked from passing through the light blocking member 50. Preferably, the light blocking member 50 is made of an elastic material, such as foam, rubber, or the like. In this way, the light blocking member 50 is prevented from being in rigid contact with the touch display screen 20 to damage the touch display screen 20.

In some embodiments, the receiver 36 is located on a side of the display layer 22 facing away from the cover 24, and the receiver 36 is configured to receive the first infrared ray and the second infrared ray reflected by the object outside the electronic device 100 through the cover 24 and the display layer 22.

Alternatively, the projection of receiver 36 onto the plane of display layer 22 is located on display layer 22. Alternatively, receiver 36 is located below display layer 22. In this way, the receiver 36 has a wider range for receiving the infrared rays, which is beneficial for receiving the first infrared rays and the second infrared rays reflected by the object outside the electronic device 100 to generate the detection information, so that the processor 40 can accurately control the display state of the display layer 22.

Referring to FIG. 6, in some embodiments, the touch display panel 20 includes a light shielding layer 26 attached to the display layer 22 opposite the cover 24. The light shielding layer 26 is formed with a first light passing hole 262 corresponding to the second emitter 34 and a second light passing hole 264 corresponding to the receiver 36. The second emitter 34 is configured to emit a second infrared ray out of the electronic device 100 through the first light passing hole 262, the display layer 22 and the cover plate 24. The receiver 36 is configured to receive the first infrared ray and the second infrared ray reflected by the object outside the electronic device 100 through the cover plate 24, the display layer 22 and the second light passing hole 264.

Since visible light can transmit through the display layer 22, if the light shielding layer 26 is omitted, a user can see the internal components of the electronic device 100 from outside the electronic device 100 through the touch display screen 20, which is not good for the appearance of the electronic device 100. In this embodiment, the light shielding layer 26 may shield visible light, so that internal components of the electronic device 100 are not visible to the outside, which may improve user experience.

Specifically, the light-shielding layer 26 may be adhesively attached to the display layer 22. Preferably, the light-shielding layer 26 is made of a soft material. For example, the light shielding layer 26 may be made of foam or foam plastic or rubber or other soft material, so as to reduce the impact of the display layer 22 from the outside and prevent the touch display screen 20 from being damaged, thereby improving the life of the touch display screen 20.

Referring to FIG. 7, in some embodiments, the touch screen display 20 includes a touch layer 28 overlying the display layer 22, the touch layer 28 being disposed between the cover 24 and the display layer 22.

Specifically, the touch layer 28 is mainly used for receiving a user input signal and transmitting the signal to the circuit board for data processing, so as to obtain a specific position where the user touches the touch layer 28. It is noted that the touch layer 28 being disposed on the display layer 22 may mean that the touch layer 28 is in contact with the display layer 22. For example, In-Cell or On-Cell technology may be used to place the touch layer 28 with the display layer 22, which may effectively reduce the weight of the display layer 22 and the overall thickness of the display layer 22.

Referring to fig. 8, in some embodiments, the electronic device 100 includes a filter element 60 disposed between the display layer 22 and the proximity sensor 30, the filter element 60 configured to transmit infrared light and intercept visible light. Alternatively, filter elements 60 are disposed between each of the first emitter 32, the second emitter 34, and the receiver 36 and the display layer 22.

Specifically, the filter element 60 may be a film or a sheet, and the form of the filter element 60 is not limited herein.

Referring to FIG. 9, in some embodiments, filter element 60 includes a transparent sheet 62 and a filter coating 64 disposed on transparent sheet 62. The filter coating 64 comprises an IR ink having a transmittance of infrared light of more than 85% and a transmittance of visible light of less than 6%, the IR ink being transmissive to infrared light at a wavelength of, for example, 850nm to 940 nm.

It can be understood that since the IR ink has a characteristic of low transmittance of visible light, the proximity sensor 30 disposed under the filter element 60 is not observed based on the visual perception of human eyes when the electronic device 100 is viewed from the outside. Meanwhile, the IR ink has a characteristic of high transmittance to infrared rays, and can enable the proximity sensor 30 to stably emit and receive infrared rays, thereby ensuring normal operation of the proximity sensor 30.

In some embodiments, the filter element 60 is attached to the proximity sensor 30. Specifically, when the filter element 60 is a film layer, the filter element 60 may be attached to the proximity sensor 30 by coating in an actual manufacturing process. When the filter element 60 is a sheet material, the filter element 60 may be attached to the proximity sensor 30 using an optical adhesive in an actual manufacturing process.

Of course, the filter element 60 may be disposed at any position between the proximity sensor 30 and the display layer 22, other than being attached to the proximity sensor 30, and the specific position of the filter element 60 is not limited herein.

Referring to fig. 10, the present application further discloses a control method of the electronic device 100, specifically, the control method includes:

s10, keeping the second emitter 34 of the proximity sensor 30 off when the first emitter 32 and the receiver 36 of the proximity sensor 30 are on, the emitting power of the first emitter 32 being greater than the emitting power of the second emitter 34;

s20, determining whether the distance between the touch display screen 20 and the object outside the electronic device 100 is less than or equal to a first predetermined distance according to the cooperation of the first transmitter 32 and the receiver 36;

s30, turning off first emitter 32 and turning on second emitter 34 when the distance is less than or equal to the first predetermined distance.

In some embodiments, the processor 40 is configured to keep the second transmitter 34 of the proximity sensor 30 off when the first transmitter 32 and the receiver 36 of the proximity sensor 30 are on, and to determine whether a distance between the touch display screen 20 and an object external to the electronic device 100 is less than or equal to a first predetermined distance based on cooperation of the first transmitter 32 and the receiver 36, and to turn off the first transmitter 32 and turn on the second transmitter 34 when the distance is less than or equal to the first predetermined distance.

In this way, by controlling the first emitter 32 and the second emitter 34 to switch on and off, not only the function of detecting the distance between the object and the electronic device 100 can be effectively realized, but also the power consumption of the proximity sensor 30 can be reduced.

Specifically, when the electronic device 100 needs to detect the distance between the object and the touch display screen 20 through the proximity sensor 30, the first transmitter 32 may be turned on and the second transmitter 34 may be turned off, and at this time, whether the external object approaches the electronic device 100 from a position far away from the electronic device 100 may be detected by using the first transmitter 32.

As shown in FIG. 11, during the approach of an object to the touch screen display 20, the first transmitter 32 and the receiver 36 are turned on, and the second transmitter 34 is turned off, at which time the first transmitter 32 and the receiver 36 can detect that the distance between the object and the touch screen display 20 is gradually reduced. As shown in FIG. 12, when the distance between an object external to the electronic device 100 and the touch screen display 20 is less than or equal to a first predetermined distance, the first transmitter 32 is turned off and both the second transmitter 34 and the receiver 36 are turned on.

It is understood that the display layer 22 may be controlled to be turned off when the distance between the touch display screen 20 and the object outside the electronic device 100 is greater than the first predetermined distance. At this time, the display screen 22 is powered off and in an off state.

In step S10, the first transmitter 32 and the receiver 36 may be turned on and the second transmitter 34 may be kept off when the electronic device 100 is powered on. In other words, the electronic device 100 turns off the first transmitter 32, the second transmitter 34, and the receiver 36 before an incoming call.

In step S20, the first predetermined distance may be specifically set based on the ability of the second transmitter 34 to cooperate with the receiver 36 to detect the distance between the object and the touch screen display 20. For example, the second transmitter 34 in cooperation with the receiver 36 detects a maximum distance of 2cm between the object and the touch screen display 20. The first predetermined distance may then be set to less than or equal to 2cm to ensure that the second transmitter 34 in cooperation with the receiver 36 can still detect the distance between the object and the touch screen display 20 after the first transmitter 32 is turned off.

It will be appreciated that the first emitter 32 and receiver 36 cooperate to detect a range of distances between an object and the touch screen display 20, and the second emitter 34 and receiver 36 cooperate to detect a range of distances between an object and the touch screen display 20 that has an overlap, such that the first emitter 32, second emitter 34 and receiver 36 cooperate to continuously detect whether an object is near the touch screen display 20 or far from the touch screen display 20.

It should be noted that the distance between the object outside the electronic device 100 and the touch display screen 20 may refer to the distance between the surface of the cover 24 and the surface of the cover 24 of the touch display screen 20 facing the object.

Referring to fig. 13, in some embodiments, the control method includes:

s40, determining whether the distance between the touch display screen 20 and the object outside the electronic device 100 is greater than or equal to a second predetermined distance according to the cooperation of the second transmitter 34 and the receiver 36, wherein the second predetermined distance is greater than the first predetermined distance;

s50, turning off second emitter 34 and turning on first emitter 32 when the distance is greater than or equal to a second predetermined distance.

In some embodiments, the processor 40 is configured to determine whether the distance between the touch screen display 20 and an object external to the electronic device 100 is greater than or equal to a second predetermined distance based on the cooperation of the second transmitter 34 and the receiver 36, and to turn off the second transmitter 34 and turn on the first transmitter 32 when the distance is greater than or equal to the second predetermined distance.

In this way, when an object outside the electronic device 100 is far away from the electronic device 100, the first transmitter 32 with larger transmission power can be turned on to enable the first transmitter 32 and the receiver 36 to cooperate to detect the object far away from the electronic device 100, and at this time, the second transmitter 34 is turned off, so that the power consumption of the proximity sensor 30 can be reduced.

As shown in FIG. 14, during a period when an object is moving away from the touch screen display 20, the second transmitter 34 and the receiver 36 remain on while the first transmitter 32 is off, at which time the second transmitter 34 and the receiver 36 may detect that the object is at an increasing distance from the touch screen display 20. As shown in FIG. 15, when the distance between an object external to the electronic device 100 and the touch screen display 20 is greater than or equal to a second predetermined distance, the second transmitter 34 is turned off, and both the first transmitter 32 and the receiver 36 are turned on.

It will be appreciated that the second predetermined distance is greater than the first predetermined distance such that when the first transmitter 32 is turned on, the first transmitter 32 cooperates with the receiver 36 to detect the distance between the object and the touch sensitive display screen 20.
