[0005] According to an embodiment of the present invention, a display device includes a display panel and an electronic module disposed under the display panel. The display panel includes: a first display region having a first pixel density and having a plurality of first regions and pixel-less regions, each of the plurality of first regions including a corresponding one of a plurality of pixels, the pixel-less regions including a plurality of second regions and a plurality of third regions, each of the plurality of third regions surrounding a corresponding one of the plurality of second regions and disposed between the corresponding second region and at least one first region of the plurality of first regions that is directly adjacent to each of the plurality of third regions; a second display region having a second pixel density greater than the first pixel density; a plurality of first pattern layers respectively disposed in the plurality of third regions, each of the plurality of first pattern layers surrounding a corresponding one of the plurality of second regions in a plan view; and a plurality of second pattern layers respectively disposed on the plurality of first pattern layers.

[0006] The first display region has a transmittance greater than that of the second display region. The transmittance of each of the plurality of second regions is greater than the transmittance of each of the plurality of first regions. The display panel further includes a circuit layer disposed in the plurality of first regions, the plurality of second regions, and the plurality of third regions. The plurality of first pattern layers and the plurality of second pattern layers are disposed on the circuit layer.

[0007] Each of the plurality of second regions is provided with a transmission opening defined in each of the plurality of second regions by removing a part of the circuit layer.

[0008] Each of the plurality of pixels includes a first electrode, a light-emitting layer, and a second electrode. The first electrode is disposed on the circuit layer.

[0009] Each of the plurality of second pattern layers controls a traveling direction of light emitted from the light-emitting layer.

[0010] Each of the plurality of first pattern layers blocks incident light from outside of the display panel.

[0011] The electronic module is superimposed on the plurality of first regions, the plurality of second regions, and the plurality of third regions in a plan view.

[0012] The display device further includes a first controller electrically connected to the display panel. The first controller controls a first pixel adjacent to a corresponding third region among the plurality of third regions among the plurality of pixels according to an operation state of the electronic module.

[0013] The first controller includes: a luminance difference calculation circuit configured to compare a first luminance of a first display region with a second luminance of a second display region to calculate a luminance difference; a memory configured to receive information on a luminance reduction amount from the luminance difference calculation circuit and store the information on the luminance reduction amount; a correction amount determination circuit configured to determine a correction amount based on the luminance reduction amount from the memory; a correction circuit configured to receive information on the correction amount from the correction amount determination circuit to control the first luminance; and a state determination circuit configured to determine an operation state of the electronic module to provide a first signal to the correction circuit.

[0014] The correction circuit outputs a second signal that turns off the first pixel in response to the first signal indicating the operation of the electronic module.

[0015] The correction circuit outputs a third signal that turns on the first pixel in response to the first signal indicating the non-operation of the electronic module.

The electronic module captures light incident from the outside into a second region and forms an image. The first pattern layer improves the quality of the image. The second pattern layer controls the traveling direction of light provided from adjacent pixels, and thus, the light travels to the outside. The light provided from the third region compensates for insufficient brightness in a first display region. Accordingly, the visibility of the display device is improved, and thus, a display device with improved reliability is provided. Brief Description of the Drawings

[0049] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0050] Figure 1 is a perspective view showing a display device DD according to an embodiment of the present invention, and Figure 2 is an exploded perspective view showing a display device DD according to an embodiment of the present invention.

[0051] Referring to Figure 1 and Figure 2, the display device DD can be a device activated in response to an electrical signal. The display device DD can include various embodiments. For example, the display device DD can be applied to large-sized electronic products (such as televisions, monitors, or outdoor billboards) and small- and medium-sized electronic products (such as personal computers, laptop computers, personal digital assistants, navigation units, gaming units, portable electronic devices, and cameras). These are merely exemplary, and thus, the display device DD can be applied to other electronic devices as long as they do not deviate from the concept of the present invention. In this exemplary embodiment, a smart phone will be described as a representative example of the display device DD.

[0052] The display device DD displays an image IM through a display surface FS, and the display surface FS is substantially parallel to a plane defined by a first direction DR1 and a second direction DR2. A third direction DR3 can be substantially perpendicular to the display surface FS. The display surface FS through which the image IM is displayed corresponds to the front surface of the display device DD and the front surface of the window 100. Hereinafter, the display surface and the front surface of the display device DD and the front surface of the window 100 are assigned the same reference numerals. The image IM includes a still image and a moving image. Figure 1 A clock widget and application icons are shown as representative examples of the image IM.

[0053] In this exemplary embodiment, the front (or upper) surface and the rear (or lower) surface of each component of the display device DD are defined with respect to the direction along which the image IM is displayed. The front surface and the rear surface face each other in the third direction DR3, and the normal direction of each of the front surface and the rear surface is substantially parallel to the third direction DR3. The third direction DR3 intersects the first direction DR1 and the second direction DR2, and the first direction DR1, the second direction DR2, and the third direction DR3 are perpendicular to each other. In the following description, the surface defined by the first direction DR1 and the second direction DR2 is defined as a planar surface, and the expression "when viewed in a plan view" can refer to viewing along the third direction DR3.

[0054] The display device DD includes a window 100, a display module 200, a driving circuit unit 300, a housing 400, and an electronic module 500. In this exemplary embodiment, the window 100 and the housing 400 are combined with each other to provide the appearance of the display device DD.

[0055] The window 100 includes an optically transparent insulating material. For example, the window 100 includes a glass or plastic material. The window 100 has a single-layer structure or a multi-layer structure. As an example, the window 100 includes a plurality of plastic films attached to each other by an adhesive or a glass substrate and a plastic film attached to the glass substrate by an adhesive.

[0056] The window 100 is divided into a transmissive area TA and a border area BZA in a plan view. The transmissive area TA is an optically transparent area. Compared with the transmissive area TA, the border area BZA is an area with a relatively low transmittance. The border area BZA defines the shape of the transmissive area TA. The border area BZA is provided adjacent to the transmissive area TA and surrounds the transmissive area TA.

[0057] The border area BZA has a predetermined color. The border area BZA covers the peripheral area NAA of the display module 200 to prevent the peripheral area NAA from being seen from the outside. However, this is merely exemplary, and according to an embodiment of the present invention, the border area BZA may be omitted from the window 100.

[0058] In an embodiment of the present invention, the window 100 includes a sensing area SSA located in the transmissive area TA. The sensing area SSA may be stacked with the electronic module 500. The display device DD may receive an external signal for the electronic module 500 through the sensing area SSA or may provide an output signal output from the electronic module 500 to the outside through the sensing area SSA. According to the present invention, the sensing area SSA may be provided to be stacked with the transmissive area TA. Therefore, a separate area provided for the sensing area SSA may be omitted in an area other than the transmissive area TA. Therefore, the size of the border area BZA may be reduced. In an exemplary embodiment, the external signal may include light or sound, and the output signal may include light or sound.

[0059] Figure 1 and [[ID=?]] Figure 2 One sensing area SSA is shown. However, the present invention is not limited thereto. In an exemplary embodiment, two or more sensing areas SSA may be defined in the transmissive area TA. Additionally, the sensing area SSA is defined at the upper left end of the transmissive area TA in Figure 1 and Figure 2 However, the present invention is not limited thereto. In an exemplary embodiment, the sensing area SSA may be defined at various positions in the transmissive area TA (such as the upper right end of the transmissive area TA, the lower left end of the transmissive area TA, or the lower right end of the transmissive area TA).

[0060] The display module 200 is disposed under the window 100. The display module 200 displays an image IM. The display module 200 includes a front surface IS in which an active area AA and a peripheral area NAA are defined. The active area AA is an area activated in response to an electrical signal. In an exemplary embodiment, pixels may be located in the active area AA, and the peripheral area NAA may be a pixel-free area.

[0061] It should be noted that there seems to be an issue with the tag [[ID=?]] in the original text which might be a misprint. I've translated it as is while keeping the original tag for reference.In the present exemplary embodiment, the active area AA is the area through which the image IM is displayed. The transmissive area TA overlaps with the active area AA. For example, the transmissive area TA overlaps with the entire surface or at least a part of the active area AA. Thus, the user perceives the image IM through the transmissive area TA.

[0062] The peripheral area NAA is covered by the border area BZA. The peripheral area NAA is provided adjacent to the active area AA. The peripheral area NAA surrounds the active area AA. A driving circuit or driving lines are provided in the peripheral area NAA to drive the active area AA.

[0063] In the present exemplary embodiment, the display module 200 is assembled in a flat state such that the active area AA and the peripheral area NAA of the display module 200 face the window 100. However, this is merely exemplary, and a part of the peripheral area NAA may be curved. In this case, the part of the peripheral area NAA is curved toward the rear surface of the display device DD, and thus, the size of the border area BZA is reduced on the front side of the display device DD. In the exemplary embodiment, the display module 200 may be assembled such that a part of the active area AA is curved. In the exemplary embodiment, the peripheral area NAA may be omitted from the display module 200.

[0064] The driving circuit unit 300 is electrically connected to the display module 200. The driving circuit unit 300 includes a main circuit board MB and a flexible film CF.

[0065] The flexible film CF is electrically connected to the display module 200. The flexible film CF is connected to pads (also referred to as "bonding pads" or "lands") disposed in the peripheral area NAA of the display module 200. The flexible film CF provides an electrical signal to the display module 200 to drive the display module 200. The electrical signal is generated by the flexible film CF or by the main circuit board MB. The main circuit board MB includes various driving circuits for driving the display module 200 or connectors for supplying power.

[0066] In the exemplary embodiment, the area of the display module 200 that overlaps with the sensing area SSA has a relatively high transmittance compared to the active area AA that does not overlap with the sensing area SSA. For example, at least some components of the display module 200 may be removed from the area of the display module 200 that overlaps with the sensing area SSA. Thus, the electronic module 500 can easily transmit and / or receive signals through the sensing area SSA. In the exemplary embodiment, the signals may include sound or light.

[0067] The electronic module 500 is disposed below the display module 200. The electronic module 500 is superimposed on the sensing area SSA in the plan view. The electronic module 500 receives an external input provided through the sensing area SSA or provides an output through the sensing area SSA. The electronic module 500 includes a camera, an infrared sensor, or a proximity sensor.

[0068] The housing 400 is coupled to the window 100. The housing 400 is coupled to the window 100 to provide an internal space in the housing 400. The display module 200 and the electronic module 500 are accommodated in the internal space.

[0069] The housing 400 has a material with relatively high rigidity. For example, the housing 400 includes a plurality of frames and / or plates made of glass, plastic, or metal materials or a combination thereof. The housing 400 stably protects the components of the display device DD accommodated in the internal space from external impacts.

[0070] Figure 3 is a cross-sectional view showing a display module 200 according to an embodiment of the present invention.

[0071] Referring to Figure 3 , the display module 200 includes a display panel 210 and an input sensing unit 220. The display panel 210 includes a first substrate layer BL, a circuit layer ML, a display element layer EML, and a thin film encapsulation layer TFE. The input sensing unit 220 includes a second substrate layer TFE and a sensing circuit layer ML-T. The thin film encapsulation layer TFE and the second substrate layer TFE may be the same layer. The reference numeral "TFE" may be used interchangeably to denote the second substrate layer and the thin film encapsulation layer.

[0072] According to an embodiment of the present invention, the display panel 210 and the input sensing unit 220 are formed by a continuous process. For example, the sensing circuit layer ML-T is directly formed on the thin film encapsulation layer (or the second substrate layer) TFE.

[0073] The first substrate layer BL is a silicon substrate, a plastic substrate, a glass substrate, an insulating film, or a stacked structure including a plurality of insulating layers.

[0074] The circuit layer ML is disposed on the first substrate layer BL. The circuit layer ML includes a semiconductor layer, a plurality of insulating layers, and a plurality of conductive layers. The conductive layers of the circuit layer ML form signal lines or pixel control circuits.

[0075] The display element layer EML is disposed on the circuit layer ML. The display element layer EML includes a light-emitting layer that emits light. For example, the light-emitting layer of an organic light-emitting display panel includes an organic light-emitting material. In an exemplary embodiment, the light-emitting layer of a quantum dot light-emitting display panel includes at least one of quantum dots and quantum rods.

[0076] The sensing circuit layer ML-T is disposed on the second substrate layer TFE. The sensing circuit layer ML-T includes a plurality of insulating layers and a plurality of conductive layers. The conductive layers form sensing electrodes for sensing external inputs such as user touches, sensing lines connected to the sensing electrodes, and sensing pads connected to the sensing lines.

[0077] Figure 4 is a cross-sectional view showing a display module 200-1 according to an embodiment of the present invention. In Figure 4 , the same reference numerals denote the same elements as those in Figure 3 , and thus, detailed descriptions of the same elements will be omitted.

[0078] Referring to Figure 4 , the display module 200-1 includes a display panel 210-1 and an input sensing unit 220-1. The display panel 210-1 includes a first substrate layer BL, a circuit layer ML, and a display element layer EML. The input sensing unit 220-1 includes a cover substrate CBL and a sensing circuit layer ML-T.

[0079] The cover substrate CBL is disposed on the display element layer EML. The cover substrate CBL is a silicon substrate, a plastic substrate, a glass substrate, an insulating film, or a stacked structure including a plurality of insulating layers. A predetermined space is defined between the cover substrate CBL and the display element layer EML. The space is filled with air or an inert gas. The present invention is not limited thereto. In an exemplary embodiment, the space may be filled with a filler such as a silicone-based polymer, an epoxy-based resin, or an acrylic-based resin.

[0080] A bonding member SLM is disposed between the first substrate layer BL and the cover substrate CBL. The bonding member SLM combines the first substrate layer BL and the cover substrate CBL. The bonding member SLM includes an organic material such as a photocurable resin or a photoplastic resin, or an inorganic material such as a frit seal. However, the present invention is not limited thereto.

[0081] Figure 5 is a plan view showing a display panel 210 according to an embodiment of the present invention.

[0082] Referring to Figure 5 , the active area AA of the display panel 210 corresponds to the active area AA (refer to Figure 2 ) of the display module 200 (refer to Figure 2 ).

[0083] A plurality of pixels PX are arranged in the active area AA. The plurality of pixels PX are arranged along a first direction DR1 and a second direction DR2. Each of the plurality of pixels PX displays one of the primary colors or a mixed color of the primary colors. The primary colors include red, green, and blue. The mixed colors include various colors such as white, yellow, cyan, or magenta. However, the colors displayed by the plurality of pixels PX should not be limited to this or restricted thereby.

[0084] A first display area DA1 and a second display area DA2 are defined in the active area AA.

[0085] An electronic module 500 (refer to Figure 2 ) is disposed below the first display area DA1. The first display area DA1 has a transmittance higher than that of the second display area DA2. Therefore, compared with the second display area DA2, signals are more easily transmitted through the first display area DA1 to the electronic module 500 (refer to Figure 2 ) and / or signals are more easily received from the electronic module 500 through the first display area DA1. Some components are omitted from the first display area DA1 to increase the transmittance. For example, some of the pixels PX arranged in the first display area DA1 are removed. In an exemplary embodiment, the first display area DA1 may have a first pixel density, and the second display area DA2 may have a second pixel density greater than the first pixel density.

[0086] The first display area DA1 overlaps with the sensing area SSA (refer to Figure 2 ) in a plan view. The first display area DA1 has a size larger than that of the sensing area SSA (refer to Figure 2 ).

[0087] The first display area DA1 and the second display area DA2 are arranged adjacent to each other in the second direction DR2. The boundary between the first display area DA1 and the second display area DA2 extends in the first direction DR1. The first display area DA1 is defined on the display panel 210 in a plan view.

[0088] Figure 6 is a plan view showing a display panel 210 according to an embodiment of the present invention. In Figure 6 , the same reference numerals denote the same elements as those in Figure 5 , and thus, detailed descriptions of the same elements will be omitted.

[0089] Refer to Figure 6 , a first display area DA1a and a second display area DA2a are defined in the active area AAa. In an embodiment of the present invention, the first display area DA1a overlaps with the sensing area SSA (refer to Figure 2) Overlay. The first display area DA1a is surrounded by the second display area DA2a.

[0090] Figure 7 is an enlarged plan view showing a part of the first display area DA1 according to an embodiment of the present invention.

[0091] Referring to Figure 7 , the first display area DA1 includes a plurality of first areas AR1, a plurality of second areas AR2, and a plurality of third areas AR3.

[0092] The plurality of first areas AR1 are areas in which a plurality of pixels PX (refer to Figure 5 ) are respectively arranged. Each of the plurality of first areas AR1 is spaced apart from other first areas AR1 among the plurality of first areas AR1 in a first direction DR1 and a second direction DR2, and one of the plurality of second areas AR2 is disposed therebetween. For example, the plurality of first areas AR1 and the plurality of second areas AR2 are alternately arranged along the first direction DR1 and along the second direction DR2. Thus, one first area AR1 is adjacent to at least one second area AR2.

[0093] The plurality of second areas AR2 are areas in which the plurality of pixels PX (refer to Figure 5 ) are not provided. Each of the plurality of second areas AR2 has a transmittance higher than that of each of the first areas AR1. Some components of the display panel 210 (refer to Figure 5 ) are omitted from each of the plurality of second areas AR2.

[0094] The number of the plurality of first areas AR1 may be the same as the number of the plurality of second areas AR2.

[0095] In Figure 7 , the sum of the sizes of the second area AR2 and the third area AR3 is substantially the same as the size of the first area AR1. However, the first area AR1, the second area AR2, and the third area AR3 according to an embodiment of the present invention should not be limited to this or restricted thereby. The required transmittance of the first display area DA1 according to the type of the display panel 210 (refer to Figure 5 ) is different. Therefore, the ratio per unit area of the first area AR1, the second area AR2, and the third area AR3 is determined according to the transmittance of the first display area DA1.

[0096] Each of the plurality of third areas AR3 is defined between each of the plurality of first areas AR1 and each of the plurality of second areas AR2. Each of the plurality of third areas AR3 surrounds the corresponding second area AR2 among the plurality of second areas AR2.

[0097] Figure 8is a cross-sectional view taken along line I-I' shown in Figure 7 as shown in the figure.

[0098] Figure 8 The cross-section shows a first region AR1, a second region AR2, and a third region AR3 disposed between the first region AR1 and the second region AR2.

[0099] The display panel 210 includes a first substrate layer BL, a circuit layer ML, a display element layer EML, and a thin film encapsulation layer TFE. The circuit layer ML provides signals for driving the light-emitting elements OD included in the display element layer EML. The pixel PX includes a transistor T1 and a light-emitting element OD.

[0100] The circuit layer ML includes a transistor T1, a first insulating layer 10, a second insulating layer 20, a third insulating layer 30, and a fourth insulating layer 40. The first insulating layer 10 is disposed on the first substrate layer BL to cover the entire surface of the first substrate layer BL. The first insulating layer 10 includes an inorganic material. The first insulating layer 10 includes a barrier layer and / or a buffer layer. Thus, the first insulating layer 10 prevents oxygen or moisture introduced through the first substrate layer BL from entering the pixel PX.

[0101] The transistor T1 is disposed on the first insulating layer 10. The transistor T1 includes a semiconductor pattern SL, a control electrode CE, a first electrode OE, and a second electrode IE. The semiconductor pattern SL includes a semiconductor material. The control electrode CE is spaced apart from the semiconductor pattern SL, and the second insulating layer 20 is disposed between the control electrode CE and the semiconductor pattern SL.

[0102] The first electrode OE and the second electrode IE extend through the second insulating layer 20 and the third insulating layer 30 to be connected to one side and the other side of the semiconductor pattern SL, respectively. However, the present invention is not limited thereto. In an exemplary embodiment, the first electrode OE and the second electrode IE may be disposed on the same layer as the semiconductor pattern SL and have a shape integrated with the semiconductor pattern SL. For example, the first electrode OE extends from one end of the semiconductor pattern SL, and the second electrode IE extends from the other end of the semiconductor pattern SL. The channel region may be the region between the second electrode IE and the first electrode OE. The transistor T1 according to an embodiment of the present invention may have various stacked structures. However, the transistor T1 should not be limited thereto or thereby restricted.

[0103] The fourth insulating layer 40 is disposed on the third insulating layer 30 to cover the first electrode OE and the second electrode IE. The fourth insulating layer 40 includes an organic material and / or an inorganic material and has a single-layer structure or a multi-layer structure.

[0104] The display element layer EML includes a light-emitting element OD and a fifth insulating layer 50. The light-emitting element OD includes a first electrode E1, a light-emitting pattern EL, and a second electrode E2. The first electrode E1 is disposed on the fourth insulating layer 40. The first electrode E1 extends through the fourth insulating layer 40 to be electrically connected to the transistor T1. In Figure 8 , the first electrode E1 is directly connected to the transistor T1. However, the present invention is not limited thereto. In an exemplary embodiment, the first electrode E1 may be electrically connected to the transistor T1 via at least one other transistor.

[0105] The fifth insulating layer 50 is disposed on the fourth insulating layer 40. The fifth insulating layer 50 is provided with a display opening D-OP defined therethrough. At least a part of the first electrode E1 is exposed through the display opening D-OP. The fifth insulating layer 50 may be referred to as a "pixel defining layer".

[0106] The light-emitting pattern EL is disposed on the first electrode E1 exposed through the display opening D-OP. The light-emitting pattern EL includes a light-emitting material. For example, the light-emitting pattern EL includes at least one of materials that emit red light, green light, and blue light. The light-emitting pattern EL includes a fluorescent material or a phosphorescent material. The light-emitting pattern EL includes an organic light-emitting material or an inorganic light-emitting material. The light-emitting pattern EL emits light in response to a potential difference between the first electrode E1 and the second electrode E2.

[0107] The second electrode E2 is disposed on the light-emitting pattern EL. The second electrode E2 includes a transparent conductive material or a semi-transparent conductive material. Therefore, the light generated by the light-emitting pattern EL easily travels through the second electrode E2 in the third direction DR3. The second electrode E2 may be commonly disposed in the pixel PX.

[0108] However, this is merely exemplary. The light-emitting element OD according to an embodiment of the present invention operates in a back surface light-emitting mode or a double-sided light-emitting mode. In the back surface light-emitting mode, the first electrode E1 includes a transparent or semi-transparent conductive material. In the double-sided light-emitting mode, light is emitted to both the front surface and the back surface. The present invention is not limited thereto.

[0109] In Figure 8 , the second electrode E2 is disposed in the first region AR1 and not in the second region AR2 and the third region AR3. However, the second electrode E2 should not be limited thereto or restricted thereby. For example, the second electrode E2 may be stacked with the first region AR1, the second region AR2, and the third region AR3.

[0110] The thin film encapsulation layer TFE is disposed on the light-emitting element OD to encapsulate the light-emitting element OD. Although not shown in the figure, a cover layer may also be disposed between the second electrode E2 and the thin film encapsulation layer TFE to cover the second electrode E2.

[0111] The thin film encapsulation layer TFE includes a first inorganic layer LIL, an organic layer OEL, and a second inorganic layer UIL that are sequentially stacked in a third direction DR3. However, the thin film encapsulation layer TFE according to an embodiment of the present invention should not be limited to this or restricted thereby. The thin film encapsulation layer TFE may further include a plurality of inorganic layers and organic layers.

[0112] The first inorganic layer LIL covers the second electrode E2. The first inorganic layer LIL prevents external moisture or oxygen from entering the light-emitting element OD. For example, the first inorganic layer LIL includes silicon nitride, silicon oxide, or a mixture thereof.

[0113] The organic layer OEL is disposed on the first inorganic layer LIL to contact the first inorganic layer LIL. The organic layer OEL provides a flat surface on the first inorganic layer LIL. An uneven shape formed on the upper surface of the first inorganic layer LIL or particles present on the first inorganic layer LIL are covered by the organic layer OEL. Thus, the influence exerted by the surface state of the upper surface of the first inorganic layer LIL on components formed on the organic layer OEL is prevented. In an exemplary embodiment, the organic layer OEL reduces stress between layers in contact with each other. The organic layer OEL includes an organic material.

[0114] The second inorganic layer UIL is disposed on the organic layer OEL to cover the organic layer OEL. The second inorganic layer UIL is stably formed on a relatively flat surface rather than being disposed on the first inorganic layer LIL. The second inorganic layer UIL prevents the wet air leaking from the organic layer OEL from flowing to the outside. The second inorganic layer UIL includes silicon nitride, silicon oxide, or a mixture thereof.

[0115] The transmissive opening T-OP is defined in the second region AR2 by removing a portion of the insulating layer included in the circuit layer ML and the display element layer EML. In an exemplary embodiment, the transmissive opening T-OP in the second region AR2 extends through the insulating layer included in the circuit layer ML and the display element layer EML. For example, the insulating layer includes a fourth insulating layer 40 and a fifth insulating layer 50.

[0116] The transmissive opening T-OP includes a first transmissive opening TO1 and a second transmissive opening TO2. The first transmissive opening TO1 and the second transmissive opening TO2 are formed to be aligned in the third direction DR3. In an exemplary embodiment, the first transmissive opening TO1 and the second transmissive opening TO2 overlap each other and are connected to each other.

[0117] The first transmission opening TO1 is defined to pass through the fourth insulating layer 40, and the second transmission opening TO2 is defined to pass through the fifth insulating layer 50. The transmission opening T-OP is covered by the first inorganic layer LIL of the thin film encapsulation layer TFE. For example, the first inorganic layer LIL covers the inner sidewalls of the transmission opening T-OP (e.g., the inner sidewalls of the first transmission opening TO1 and the second transmission opening TO2). The first inorganic layer LIL also covers the upper surface of the third insulating layer 30 exposed by the transmission opening T-OP.

[0118] Since no pixel PX is provided in the second region AR2, the second region AR2 has a relatively high light transmittance compared to the first region AR1.

[0119] The third region AR3 is defined between the first region AR1 and the second region AR2. The first pattern layer PT1 and the second pattern layer PT2 are provided in the third region AR3. In an exemplary embodiment, the width of the first pattern layer PT1 measured in the first direction DR1 is greater than the width of the second pattern layer PT2 measured in the first direction DR1.

[0120] The first pattern layer PT1 is provided on the fifth insulating layer 50. The first pattern layer PT1 surrounds the second region AR2 in a plan view. The first pattern layer PT1 blocks the incident light toward the display panel 210. For example, the first pattern layer PT1 includes a light blocking layer that prevents incident light from entering Figure 2 the electronic module 500.

[0121] The second pattern layer PT2 is provided on the first pattern layer PT1. The second pattern layer PT2 surrounds the second region AR2 in a plan view. The second pattern layer PT2 controls the path of the outgoing light from the first region AR1 to increase the brightness of the outgoing light from the first region AR1. For example, the second pattern layer PT2 can be used as a light guiding layer to increase the brightness of, for example, the first region AR1. For example, in Figure 7 the second pattern layer PT2 provided in the third region AR3 can increase the brightness of each of the four first regions AR1 directly adjacent to the third region AR3.

[0122] The first inorganic layer LIL covers the first pattern layer PT1 and the second pattern layer PT2.

[0123] Figure 9 is an enlarged plan view showing a part of the first display area DA1-1 according to an embodiment of the present invention. In Figure 9 the same reference numerals denote the same elements as those in Figure 7 therefore, detailed descriptions of the same elements will be omitted.

[0124] Referring to Figure 9, the first display area DA1-1 includes a plurality of first areas AR1-1, a plurality of second areas AR2-1, and a plurality of third areas AR3-1.

[0125] The plurality of first areas AR1-1 are arranged adjacent to each other. The plurality of second areas AR2-1 are arranged adjacent to each other. For example, two of the plurality of first areas AR1-1 are arranged adjacent to each other in the second direction DR2. Two of the plurality of second areas AR2-1 are arranged adjacent to each other in the second direction DR2. Two first areas AR1-1 arranged adjacent to each other in the second direction DR2 and two second areas AR2-1 arranged adjacent to each other in the second direction DR2 are alternately arranged along the first direction DR1.

[0126] Figure 10 is an enlarged plan view showing a part of the first display area DA1-2 according to an embodiment of the present invention. In Figure 10 the same reference numerals denote the same elements as those in Figure 7 Therefore, the detailed description of the same elements will be omitted.

[0127] Referring to Figure 10 , the first display area DA1-2 includes a plurality of first areas AR1-2, a plurality of second areas AR2-2, and a plurality of third areas AR3-2.

[0128] The plurality of first areas AR1-2 are arranged adjacent to each other. The plurality of second areas AR2-2 are arranged adjacent to each other. For example, two of the plurality of first areas AR1-2 are arranged adjacent to each other in the first direction DR1. Two of the plurality of second areas AR2-2 are arranged adjacent to each other in the first direction DR1. Two first areas AR1-2 arranged adjacent to each other in the first direction DR1 and two second areas AR2-2 arranged adjacent to each other in the first direction DR1 are alternately arranged along the second direction DR2.

[0129] In an exemplary embodiment, each of the plurality of first areas and each of the plurality of second areas are alternately arranged along one direction (e.g., along the first direction DR1 in Figure 7 , along the first direction DR1 in Figure 9 , along the second direction DR2 in Figure 10 ). At least N first areas among the plurality of first areas and at least N second areas among the plurality of second areas are alternately arranged along another direction different from the one direction (e.g., along the second direction DR2 in Figure 7 , along the second direction DR2 in Figure 9 , along the second direction DR2 in Figure 10alternately arranged along the first direction DR1). N is an integer equal to or greater than one. For example, in Figure 7 N is one, and in Figure 9 and Figure 10 N is two. In Figure 7 , Figure 9 and Figure 10 the number of the plurality of first regions is equal to the number of the plurality of second regions.

[0130] Figure 11 is an enlarged plan view showing a part of the first display region DA1-3 according to an embodiment of the present invention. In Figure 11 the same reference numerals denote the same elements as those in Figure 7 , and thus, the detailed description of the same elements will be omitted.

[0131] Referring to Figure 11 , the first display region DA1-3 includes a plurality of first regions AR1-3, a plurality of second regions AR2-3, and a plurality of third regions AR3-3.

[0132] The number of the plurality of first regions AR1-3 is less than the number of the plurality of second regions AR2-3. For example, each of the first regions AR1-3 is configured with three second regions AR2-3. Since the number of the plurality of second regions AR2-3 having a transmittance higher than that of the plurality of first regions AR1-3 is greater than the number of the plurality of first regions AR1-3, the first display region DA1-3 has a transmittance higher than that of the second display region DA2 (refer to Figure 5 ).

[0133] Each of the plurality of first regions AR1-3 is spaced apart from another first region AR1-3 and one second region AR2-3 is disposed therebetween. In an exemplary embodiment, the plurality of first regions AR1-3 are spaced apart from each other and each of the plurality of second regions AR2-3 is disposed between a pair of adjacent first regions AR1-3 among the plurality of first regions AR1-3. In this case, the number of the plurality of first regions AR1-3 is less than the number of the plurality of second regions AR2-3.

[0134] Figure 12 is an enlarged plan view showing a part of the second display region DA2 according to an embodiment of the present invention.

[0135] Referring to Figure 7 and Figure 12 , the second display region DA2 includes a plurality of first regions AR1. For example, the second display region DA2 may be a region defined only by the plurality of first regions AR1. The plurality of first regions AR1 are regions in which a plurality of pixels PX are provided (refer to Figure 5) region. In an exemplary embodiment, the second display region DA2 has a pixel density (e.g., 16 pixels per predetermined region, such as a 4×4 pixel array) greater than the pixel density of the first display region DA1 (e.g., 8 or 4 pixels per predetermined region).

[0136] A plurality of first regions AR1, a plurality of second regions AR2, and a plurality of third regions AR3 are arranged in the first display region DA1, and a plurality of first regions AR1 are arranged in the second display region DA2. In the same area, the number of the plurality of first regions AR1 in the first display region DA1 is different from the number of the plurality of first regions AR1 in the second display region DA2. For example, the number of the plurality of first regions AR1 in the first display region DA1 is less than the number of the plurality of first regions AR1 in the second display region DA2. Therefore, the transmittance of the first display region DA1 is higher than the transmittance of the second display region DA2.

[0137] Figure 13A is a block diagram showing a first controller CT1, a second controller CT2, and a display panel 210 according to an embodiment of the present invention, and Figure 13B is a flowchart showing the operation of a display device DD according to an embodiment of the present invention.

[0138] Referring to Figure 13A and Figure 13B the display device DD (referring to Figure 1 ) includes a first controller CT1 and a second controller CT2, and the first controller CT1 and the second controller CT2 are electrically connected to the display panel 210.

[0139] The first controller CT1 is electrically connected to the first display region DA1. The first controller CT1 includes a luminance difference calculation circuit S100, a memory S200, a correction amount determination circuit S300, a correction circuit S400, and a state determination circuit S500. The first controller CT1 receives luminance data DATA1 from the outside. The luminance data DATA1 includes the cumulative luminance data of the first display region DA1. The luminance data DATA1 is provided to the luminance difference calculation circuit S100 and the state determination circuit S500.

[0140] The luminance difference calculation circuit S100 receives the luminance data DATA1, and compares the first luminance of the first display region DA1 with the second luminance of the second display region DA2 to calculate the difference between the first luminance and the second luminance. The luminance difference calculation circuit S100 uses the difference to calculate information about the luminance reduction amount.

[0141] The memory S200 receives and stores the information about the luminance reduction amount from the luminance difference calculation circuit S100.

[0142] The correction amount determination circuit S300 determines a correction amount for correcting insufficient brightness in the first display area DA1 based on information about the amount of brightness reduction stored in the memory S200.

[0143] The state determination circuit S500 is connected to the electronic module 500. The state determination circuit S500 receives the brightness data DATA1. The state determination circuit S500 determines the operating state of the electronic module 500 and provides a signal to the correction circuit S400. The signal includes information SG1 indicating that the electronic module 500 is operating or includes information SG2 indicating that the electronic module 500 is not operating.

[0144] The correction circuit S400 is connected to the correction amount determination circuit S300 and the state determination circuit S500. The correction circuit S400 receives correction amount information from the correction amount determination circuit S300. The correction circuit S400 receives the signal from the state determination circuit S500. The correction circuit S400 controls the first brightness. For example, the correction circuit S400 controls a plurality of pixels PX arranged in the first display area DA1 (refer to Figure 5 ) based on the correction amount information such that the first brightness has a value approximately the same as that of the second brightness.

[0145] The display device DD (refer to Figure 1 ) checks the brightness data DATA1, determines the state of the electronic module 500, and checks the correction amount information, and is controlled in a first state ST1 as a light blocking state or a second state ST2 as a light guiding state according to the state of the electronic module 500.

[0146] The first state ST1 corresponds to the state in which the electronic module 500 is operating. The state determination circuit S500 provides information SG1 indicating that the electronic module 500 is operating to the correction circuit S400, and the correction circuit S400 controls the display device DD (refer to Figure 1 ) in the first state ST1.

[0147] The second state ST2 corresponds to the state in which the electronic module 500 is not operating. The state determination circuit S500 provides information SG2 indicating that the electronic module 500 is not operating to the correction circuit S400, and the correction circuit S400 controls the display device DD (refer to Figure 1 ) in the second state ST2.

[0148] The second controller CT2 is electrically connected to the second display area DA2. The second controller CT2 provides a signal for driving the display panel 210.

[0149] Meanwhile, although not shown in the figure, the first controller CT1 and the second controller CT2 are connected to the main circuit board MB (refer to Figure 2) However, this is merely exemplary. The first controller CT1 and the second controller CT2 according to embodiments of the present invention may be connected to different main circuit boards from each other, and one of the first controller CT1 and the second controller CT2 may not be connected to the main circuit board. However, the first controller CT1 and the second controller CT2 should not be particularly limited.

[0150] Figure 14 is a cross-sectional view showing a part of the first display area DA1 according to an embodiment of the present invention. In Figure 14 the same reference numerals denote the same elements as those in Figure 8 Therefore, detailed descriptions of the same elements will be omitted.

[0151] Referring to Figure 13A 、 Figure 13B and Figure 14 , the electronic module 500 is disposed below the first display area DA1. The electronic module 500 overlaps with the first area AR1, the second area AR2, and the third area AR3 in a plan view. In an embodiment of the present invention, the electronic module 500 may include a camera.

[0152] When the electronic module 500 is not operating, the state determination circuit S500 transmits a signal including the information SG2 indicating that the electronic module 500 is not operating to the correction circuit S400. The correction circuit S400 controls the display device DD (refer to Figure 1 ) in the second state ST2. The correction circuit S400 outputs a signal that turns on the adjacent pixels PX-1 (refer to Figure 5 ) among the plurality of pixels PX that are adjacent to the third area AR3.

[0153] The light-emitting pattern EL of the adjacent pixels PX-1 emits light OL. A part of the light OL emitted from the adjacent pixels PX-1 is provided to the second pattern layer PT2. The second pattern layer PT2 controls the traveling direction of the light OL and provides the first light OL-1. For example, the second pattern layer PT2 provides the first light OL-1 in the third direction DR3. The first area AR1 and the third area AR3 provide light to the outside. The light-emitting pattern EL has increased brightness compared to if the first display area DA1 does not include the second pattern layer PT2.

[0154] According to the present invention, the second pattern layer PT2 controls the traveling direction of the light OL provided from the adjacent pixels PX-1 and provides the first light OL-1 to the outside. The third area AR3 provides the first light OL-1 to the outside. The first light OL-1 provided from the third area AR3 compensates for the insufficient brightness in the first display area DA1. The first brightness of the first display area DA1 has a value approximately the same as the value of the second brightness of the second display area DA2 (refer to Figure 5 ) and the display device DD (refer toFigure 2 ) The visibility is increased. Accordingly, a display device DD with increased reliability is provided (refer to Figure 2 ).

[0155] Figure 15 is a cross-sectional view showing a part of a first display area DA1 according to an embodiment of the present invention. In Figure 15 , the same reference numerals denote the same elements as those in Figure 8 and Figure 14 , and thus, detailed descriptions of the same elements will be omitted.

[0156] Referring to Figure 13A , Figure , ​ and ​ , the electronic module 500 captures the light LT incident thereon from the outside to form an image. The light LT includes a first light LT-1 and a second light LT-2. The first light LT-1 is transmitted through the display panel 210 toward the electronic module 500 in the second area AR2. The second light LT-2 is provided between the first area AR1 and the second area AR2. For example, the second light LT-2 is provided to the third area AR3.

[0157] When the electronic module 500 operates, the state determination circuit S500 transmits a signal including information SG1 indicating the operation of the electronic module 500 to the correction circuit S400. The correction circuit S400 controls the display device DD (refer to ​ ) in the first state ST1. The correction circuit S400 outputs a signal that turns off the adjacent pixels PX-1 adjacent to the third area AR3 among the pixels PX. The turned-off adjacent pixels PX-1 prevent the image captured by the electronic module 500 from being affected by the light OL.

[0158] The second light LT-2 may be diffracted, refracted, or reflected by the step difference between the first area AR1 and the second area AR2, and thus, the image may be distorted. However, according to the present invention, the first pattern layer PT1 blocks the second light LT-2. Since the first pattern layer PT1 blocks the second light LT-2, image distortion is prevented. The electronic module 500 captures the first light LT-1 and forms an image. The first pattern layer PT1 improves the quality of the image. Accordingly, a display device DD with increased reliability is provided (refer to ​ ).
