Description

Technology Field

[0001] Various embodiments of the present disclosure relate to electronic devices including sensors. Background Technology

[0002] Electronic devices, for example, portable electronic devices, are released in various sizes depending on their functions and user preferences, and may include a large touch screen display to ensure wide visibility and ease of operation. The electronic device may include at least one image sensor (e.g., camera module), a proximity sensor, or a fingerprint sensor. For example, the electronic device may include at least one image sensor (e.g., camera module) positioned around the display or through at least a part of the display. The problem to be solved

[0003] Organic light-emitting diode (OLED) panels and multiple sensors are applied to electronic devices. Mobile devices include a display, and an image sensor (e.g., camera module), a proximity sensor, or a fingerprint sensor may be placed on the underside of the display panel. When a fingerprint sensor is placed on the underside of the display panel, the corresponding portion of some layers constituting the display (e.g., adhesive, PET) may be perforated. As an example, some layers on the back of the display panel (e.g., PET layer, and / or adhesive layer) may have a perforated portion where the fingerprint sensor is placed. Consequently, a phenomenon may occur where the area where the fingerprint sensor is placed appears darker than other areas.

[0004] A driving circuit for emitting light from pixels may include a plurality of LTPS (low-temperature polycrystalline silicon) TFTs (thin film transistors). When a proximity sensor emits light, a photoelectric effect occurs in the area where the proximity sensor is placed, and leakage current may flow in the LTPS TFTs of the driving circuit due to the threshold voltage being approximately 1.11 eV low. If leakage current flows in the LTPS TFTs, the OLED of the corresponding pixel may emit light unintentionally.

[0005] Alternatively, external light may be reflected by the fingerprint sensor and / or air gap, causing leakage current to flow in the LTPS TFTs of the surrounding driving circuit, which may cause the OLED of the corresponding pixel to emit light unintentionally.

[0006] According to various embodiments of the present disclosure, a driving circuit for emitting pixels of a display can be configured with an oxide TFT having a high energy band gap to prevent leakage current. By preventing the flow of leakage current to the TFTs of the driving circuit, unintended emission of the OLED and / or changes in the brightness of the OLED can be prevented. means of solving the problem

[0121] FIG. 9 is a drawing showing that a proximity sensor (e.g., IR sensor (1070)) is applied to an electronic device (1000) according to various embodiments of the present disclosure.

[0122] Referring to FIG. 9, the electronic device (1000) may include a proximity sensor (1070, e.g., IR sensor), a display panel (1020), a polarizing layer (1040, POL), an adhesive layer (1050, OCA), and a window glass (1060, Window Glass).

[0124] In one embodiment, at least a portion of the display panel (1020), polarizing layer (1040, POL), adhesive layer (1050, OCA), and / or window glass (1060, Window Glass) may be included in the display device (160) of FIG. 1, the display (10) of FIG. 2, or the display (400) of FIG. 5. In one embodiment, the window glass (1060, Window Glass) may be included in the front plate (202) of FIG. 3 or the front plate (320) of FIG. 5.

[0125] In one embodiment, a portion of the back surface of the display panel (1020) (e.g., PET (1012) layer, adhesive layer (1011, 1013, adhesive layer)) may have an opening in the portion where a proximity sensor (1070, e.g., IR sensor) is placed. For example, a portion of the back surface of the display panel (1020) corresponding to a light-emitting area (1015) where light emitted from the LED (1072) of the proximity sensor (1070) is irradiated may have an opening. For example, the PET (1012) layer may be a cushion layer and may absorb at least a portion of the external force applied to the display panel (1020). An opening may be formed in at least a portion of the PET (1012) to place the proximity sensor (1070). In another embodiment, the PET (1012) may be an elastic sponge or rubber material, for example. A first adhesive layer (1011) may be placed on the upper part of the PET (1012), and a second adhesive layer (1013) may be placed on the lower part of the PET (1012).

[0126] A first adhesive layer (1011), PET (1012), and a second adhesive layer (1013) may be attached below the display panel (1020). By means of the first adhesive layer (1011), PET (1012), and the second adhesive layer (1013), light generated from the LED (1072) can be prevented from directly entering the photodiode (1074, PD).

[0127] A proximity sensor (1070) may be placed at a certain distance from the bottom of the display panel (1020). The proximity sensor (1070) may include an LED (1072) that emits light toward the display panel (1020) and a photodiode (1704, PD) that receives light.

[0128] In one embodiment, some layers on the back surface of the display panel (1020) (e.g., PET (1012) layer, first adhesive layer (1011), and second adhesive layer (1013)) may have a portion corresponding to the LED (1072) of the proximity sensor (1070) open.

[0129] As one embodiment, the PET (1012) layer, the first adhesive layer (1011), and the second adhesive layer (1013) in the portion corresponding to the light-emitting region (1015) of the LED (1702) may be perforated.

[0130] In one embodiment, some layers on the back of the display panel (e.g., PET (1012) layer, first adhesive layer (1011), and second adhesive layer (1013)) may have a portion corresponding to the photodiode (1074) of the proximity sensor (1070) open.

[0131] As one embodiment, in order to prevent leakage current from occurring in the TFTs located in the pixel circuit when external light is incident and the LED (1072) of the proximity sensor (1070) emits light, oxide TFTs with a relatively high energy band gap may be placed in the second pixel circuit (e.g., the second pixel circuit (722) of FIG. 8b) located in the sensor area (1030) (e.g., the proximity sensor area (602) or fingerprint sensor area (603) of FIG. 6) according to the arrangement of the proximity sensor (1070). Here, the range of the sensor area (1030) can be set by taking into account the light-emitting area (1015) of the proximity sensor (1070).

[0132] As one embodiment, the range of the sensor area (1030) can be formed based on the light-emitting area (1015) of the proximity sensor (1070). The light-emitting area (1015) of the proximity sensor (1070) may be an area where light substantially reaches as the LED (1072) emits light. As an example, the light-emitting area (1015) may be an area where light is transmitted as a light-emitting body emits light on the display panel (1020).

[0133] For example, the sensor area (1030) may be formed to be narrower or wider than the light-emitting area (1015). As one embodiment, the range of the sensor area (1030) may be formed to be wider than the light-emitting area (1015) of the proximity sensor (810).

[0134] As one embodiment, the second pixel circuits (e.g., the second pixel circuit (722) of FIG. 8b) of the sensor area (1030) of the display panel (1020) may include oxide TFTs with a high energy band gap of 2.5 to 5.0 [eV].

[0135] As another embodiment, the first pixel circuits (e.g., the first pixel circuit (712) of FIG. 8a) of the display area (e.g., the display area (610) of FIG. 6) excluding the sensor area (1030) may include LTPS TFTs having an energy band gap of 1.10 to 1.20 [eV].

[0136] As one embodiment, since sunlight generates a photoelectric effect of approximately 1.10 to 2.50 [eV], if an oxide TFT with an energy band gap of 2.5 to 5.0 [eV] is placed in the second pixel circuit of the sensor area (1030) of the display panel (1020), leakage current caused by external light can be prevented.

[0137] As one embodiment, the second pixel circuits of the sensor area (1030) of the display panel (1020) may include oxide TFTs (e.g., IGZO TFTs) (e.g., oxide TFTs (920) of FIG. 10a) comprising an IGZO active layer (e.g., active layer (921) of FIG. 10a) composed of indium (In), gallium (Ga), zinc (Zo), and oxygen (O) having an energy band gap of 3.10 to 3.50 [eV].

[0138] The active layer (e.g., the active layer (921) of FIG. 10a) of an oxide TFT (e.g., the oxide TFT (920) of FIG. 10a) may be a layer formed to allow current to flow on a substrate (e.g., glass or polyimide) (e.g., the substrate (902) of FIG. 10a), and the active layer may have an electrode, such as a gate (e.g., the gate (922) of FIG. 10a), a source, and a drain (e.g., the source / drain (923) of FIG. 10a) formed thereon.

[0139] As one embodiment, the pixel circuits of the sensor area (1030) of the display panel (1020) may include ITZO TFTs comprising an active layer of ITZO (Indium Tin Zinc Oxide) having an energy band gap of 3.10 to 3.50 [eV]. The ITZO TFT may include indium, tin, zinc, and oxygen.

[0140] Not limited to this, TFTs including an active layer having an energy band gap of 2.5 to 5.0 [eV] can be applied to the pixel circuit of the sensor area (1030) of the display panel (1020).

[0142] Referring to FIG. 9 and FIG. 10a, the TFTs (T1 to T8) of the second pixel circuit (e.g., the second pixel circuit (722) of FIG. 8b) located in the sensor area (1030) of the display panel (1020) may be oxide TFTs (920) (e.g., IGZO TFT or ITZO TFT). The oxide TFTs (920) (e.g., IGZO TFT or ITZO TFT) may be formed in a top gate manner.

[0143] As one embodiment, a buffer layer (904) may be disposed on a substrate (902, e.g., glass).

The active layer (921) and the source / drain (923) can be electrically connected through a contact penetrating the gate insulating layer (906) and the interlayer insulating film (908). Through this, an oxide TFT (920) can be formed. A planarization layer (910) can be placed to cover the source / drain (923) of the oxide TFT (920). An anode electrode (912) of the OLED can be placed on the planarization layer (910). The anode electrode (912) can be formed of a transparent conductive material (e.g., indium tin oxide (ITO)).

[0145] Referring to FIG. 9 and FIG. 10b, the TFTs (T1 to T8) of the second pixel circuit (e.g., the second pixel circuit (722) of FIG. 8b) located in the sensor area (1030) of the display panel (1020) may be oxide TFTs (920-1) (e.g., IGZO TFT or ITZO TFT). The oxide TFTs (920-1) (e.g., IGZO TFT or ITZO TFT) may be formed in a bottom gate manner.

[0146] As one embodiment, a buffer layer (904-1) may be disposed on a substrate (902-1, e.g., glass). A gate insulating layer (906-1, GI) may be disposed on the buffer layer (940-1). A gate (922-1) may be disposed on the gate insulating layer (906-1). An interlayer insulating film (908-1) may be disposed to cover the gate (922-1). An active layer (921-1) comprising an oxide (e.g., IGZO or ITZO) may be disposed on the interlayer insulating film (908-1). A source / drain (923-1, SD) electrically connected to the active layer (921-1) may be disposed. A source may be disposed on one side of the interlayer insulating film (908-1), and a drain may be disposed on the other side. Through this, an oxide TFT (920-1) can be formed.

[0147] FIG. 11 is a drawing showing a fingerprint sensor (1170) applied to an electronic device (1100) according to various embodiments of the present disclosure.

[0148] Referring to FIG. 11, an electronic device (1100) according to various embodiments of the present disclosure may include a fingerprint sensor (1170), a display panel (1120), a polarizing layer (1140, POL), an adhesive layer (1150, OCA), and a window glass (1160, Window Glass).

[0149] According to various embodiments of the present disclosure, a fingerprint sensor (1170) may be disposed on the lower part of a display panel (1120). A resin layer (1180) may be disposed between the display panel (1120) and the fingerprint sensor (1170). A polarizing layer (1140, POL) may be disposed on the display panel (1120). An adhesive layer (1150, OCA) may be disposed on the polarizing layer (1140, POL). A window glass (1160, Window Glass) may be disposed on the adhesive layer (1150, OCA).

[0150] In one embodiment, some layers on the back surface of the display panel (1120) (e.g., PET (1112) layer, first adhesive layer (1111), and second adhesive layer (1113)) may have a portion where the fingerprint sensor (1170) is placed. For example, the PET (1112) layer may be a cushion layer and may absorb at least a portion of the external force applied to the display panel (1120). In another embodiment, the PET (1112) may be an elastic sponge or rubber material, for example. The first adhesive layer (1111) may be placed on the upper side of the PET (1112), and the second adhesive layer (1113) may be placed on the lower side of the PET (1112).

[0151] As one embodiment, leakage current may occur in the TFTs of the sensor area (1130) upon incidence of external light (e.g., sunlight). To prevent leakage current from occurring in the TFTs of the sensor area (1130), oxide TFTs with a relatively higher energy band gap than LTPS TFTs may be placed in the sensor area (1130) according to the placement of the fingerprint sensor (1170) in the display panel (1120). Here, the sensor area (1130) may be formed around the main surface of the display area (1110) and the fingerprint sensor (1170).

[0152] As one embodiment, leakage current may occur in the TFTs of the sensor area (1130) when at least a portion of the display area (1110) around the fingerprint sensor (1170) emits light. To prevent leakage current from occurring in the TFTs of the sensor area (1130), oxide TFTs with a relatively higher energy band gap than LTPS TFTs may be placed in the sensor area (1130) according to the placement of the fingerprint sensor (1170) in the display panel (1120). Here, the sensor area (1130) may be formed on the main surface of the display area (1110) and around the fingerprint sensor (1170).

[0153] In one embodiment, when the fingerprint sensor (1170) includes an IR emitter, leakage current may occur in the TFTs of the sensor area (1130) when at least a portion of the display area (1110) around the fingerprint sensor (1170) emits light due to the emission of the IR emitter. To prevent leakage current from occurring in the TFTs of the sensor area (1130), oxide TFTs having a relatively higher energy band gap than LTPS TFTs may be placed in the sensor area (1130) according to the placement of the fingerprint sensor (1170) in the display panel (1120). Here, the sensor area (1130) may be formed around the main surface of the display area (1110) and the fingerprint sensor (1170).

[0154] As an example, the range of the sensor area (1130) can be set by considering the area of ​​the fingerprint sensor (1170).

[0155] As one embodiment, since a resin layer (1180) is disposed on top of the fingerprint sensor (1170), an LTPS TFT can be disposed in the portion of the display panel (1120) where the fingerprint sensor (1170) and the resin layer (1180) overlap.

[0156] As one embodiment, a sensor area (1130) may be located in the area corresponding to the border portion of the fingerprint sensor (1170) in the display panel (1120) and the area between the resin layer (1180) and the PET (1112). Here, a sensor area (1130) may also be located in the area of ​​the display panel (1120) that overlaps with the PET (1112).

[0157] If the fingerprint sensor (1170) includes an IR emitter, the range of the sensor area (1130) can be formed wider outward from the fingerprint sensor (1170) by considering the position where the fingerprint sensor (1170) is placed. As one embodiment, the pixel circuits (e.g., the second pixel circuit (722) in FIG. 8b) of the sensor area (1130) in the display panel (1120) may include oxide TFTs with a high energy band gap of 2.5 to 5.0 [eV]. On the other hand, the pixel circuits (e.g., the first pixel circuit (712) in FIG. 8a) of the display area (1110) excluding the sensor area (1130) may include LTPS TFTs with an energy band gap of 1.10 to 1.20 [eV].

[0158] As one embodiment, if an oxide TFT with an energy band gap of 2.5 to 5.0 [eV] is placed in the pixel circuit (e.g., the second pixel circuit (722) of FIG. 8b) of the sensor area (1130), the occurrence of leakage current of the TFT due to external light can be prevented.

[0159] As one embodiment, the pixel circuits (e.g., the second pixel circuit (722) of FIG. 8b) of the sensor area (1130) of the display panel (1120) may include IGZO TFTs comprising an IGZO active layer composed of indium (In), gallium (Ga), zinc (Zo), and oxygen (O) having an energy band gap of 3.10 to 3.50 [eV].

[0160] As one embodiment, the pixel circuits (e.g., the second pixel circuit (722) of FIG. 8b) of the sensor area (1130) of the display panel (1120) may include ITZO TFTs comprising an active layer of ITZO (Indium Tin Zinc Oxide) having an energy band gap of 3.10 to 3.50 [eV].

[0161] Not limited to this, TFTs including an active layer having an energy band gap of 2.5 to 5.0 [eV] can be applied to pixel circuits (e.g., the second pixel circuit (722) of FIG. 8b) of a sensor area (1130) in a display panel (1120).

[0162] FIG. 12 is a drawing showing a fingerprint sensor (1270) applied to an electronic device (1200) according to various embodiments of the present disclosure.

[0163] Referring to FIG. 12, the electronic device (1200) may include a fingerprint sensor (1270), a display panel (1220), a polarizing layer (1240, POL), an adhesive layer (1250, OCA), and a window glass (1260, Window Glass).

[0164] A fingerprint sensor (1270) may be placed on the lower part of the display panel (1220). An air gap (1280) may be formed between the display panel (1220) and the fingerprint sensor (1270). A polarizing layer (1240, POL) may be placed on the display panel (1220). An adhesive layer (1250, OCA) may be placed on the polarizing layer (1240, POL). A window glass (1260, Window Glass) may be placed on the adhesive layer (1250, OCA).

[0165] In one embodiment, some layers on the back surface of the display panel (1220) (e.g., PET (1212) layer, first adhesive layer (1211), and second adhesive layer (1213) may have a portion where the fingerprint sensor (1270) is placed. For example, the PET (1212) layer may be a cushion layer and may absorb at least a portion of the external force applied to the display panel (1220). In another embodiment, the PET (1212) may be an elastic sponge or rubber material, for example. The first adhesive layer (1211), PET (1212), and second adhesive layer (1213) may be attached to the underside of the display panel (1220). The first adhesive layer (1211) may be placed on the upper side of the PET (1212), and the second adhesive layer (1213) may be placed on the lower side of the PET (1212).

[0166] External light is reflected by the fingerprint sensor (1270) and / or the air gap (1280), causing leakage current to flow in the LTPS TFTs of the pixel circuit (e.g., the first pixel circuit (712) of FIG. 8a) around the fingerprint sensor (1270), which may cause the OLED of the corresponding pixel to emit light unintentionally. In one embodiment, the reflection of external light by the fingerprint sensor (1270) and / or the air gap (1280) can be prevented or reduced by the first adhesive layer (1211), PET (1212), and the second adhesive layer (1213). In one embodiment, PET (1212) is placed around the fingerprint sensor (1270) to prevent external light from being reflected by the fingerprint sensor (1270) and / or the air gap (1280). By preventing external light from being reflected by the air gap (1280), leakage current can be prevented in the TFTs.

[0167] In one embodiment, if the fingerprint sensor (1270) includes an IR emitter, the range of the sensor area (1230) can be formed according to the arrangement of the fingerprint sensor (1270). In one embodiment, the range of the sensor area (1270) can be formed wider outside the fingerprint sensor (1270). For example, the range of the sensor area (1270) can be formed wider than the area of ​​the fingerprint sensor (1270).

[0168] As an example, a sensor area (1230) may be located between the display area (1210) and the area corresponding to the fingerprint sensor (1270). In this case, the sensor area (1230) may be located so as to partially overlap with the area corresponding to the fingerprint sensor (1270).

[0169] Pixel circuits (e.g., the second pixel circuit (722) of FIG. 8b) of the sensor area (1230) of the display panel (1220) may include oxide TFTs with a high energy band gap of 2.5 to 5.0 [eV]. According to another embodiment, pixel circuits (e.g., the first pixel circuit (712) of FIG. 8a) of the display area (1210) excluding the sensor area (1230) may include LTPS TFTs with an energy band gap of 1.10 to 1.20 [eV].

[0170] If an oxide TFT with an energy band gap of 2.5 to 5.0 [eV] is placed in the pixel circuit of the sensor area (1230), leakage current caused by external light can be prevented.

[0171] FIG. 13 is a drawing showing a fingerprint sensor applied to an electronic device according to various embodiments of the present disclosure.
