Description

[0001] Cross-reference to related applications

[0002] This application claims priority and benefit to Korean Patent Application No. 10-2020-0110628, filed on August 31, 2020, with the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0003] Examples of embodiments relate to compositions for optoelectronic devices, and optoelectronic devices, image sensors, and electronic devices including the same. Background Technology

[0004] Optoelectronic devices can convert light into electrical signals using the photoelectric effect. Optoelectronic devices can include photodiodes, phototransistors, etc., and can be applied to image sensors, etc.

[0005] Image sensors, including photodiodes, require high resolution and therefore small pixels. Currently, silicon photodiodes are widely used. In some cases, silicon photodiodes exhibit degraded sensitivity due to the relatively small absorption area resulting from the relatively small pixels. Therefore, organic materials that can replace silicon have been investigated. Summary of the Invention

[0006] Examples of embodiments provide compositions for optoelectronic devices that selectively absorb light in the green wavelength region and have improved thermal stability. Such compositions may be organic materials of the optoelectronic device or may be included in organic materials of the optoelectronic device, which may have a relatively high extinction coefficient and selectively absorb light in specific wavelength regions depending on their molecular structure, and thus can simultaneously replace photodiodes and color filters, resulting in improved sensitivity and contributing to relatively high integration.

[0007] Some implementation examples also provide optoelectronic devices that can selectively absorb light in the green wavelength region and maintain improved efficiency in processes under high-temperature conditions.

[0008] Some exemplary implementations also provide an image sensor that includes the aforementioned optoelectronic device.

[0009] Some exemplary implementations also provide electronic devices that include the image sensor.

[0010] According to some exemplary embodiments, the composition for use in optoelectronic devices includes p-type semiconductor compounds and n-type semiconductor compounds represented by chemical formula 1.

[0769] In addition, the composition for optoelectronic devices can exhibit improved residual charge characteristics while having high wavelength selectivity (narrow FWHM) and absorption coefficient, thereby reducing the afterimage of the device.

[0770] The composition for optoelectronic devices can be formed into a thin film by co-depositing a p-type semiconductor compound and an n-type semiconductor compound. The deposition method provides a uniform thin film and has a low possibility of impurities being included (trapped) into the film; however, when the compound has a melting point lower than the temperature used for deposition, products from the decomposition of the compound can be deposited, and thus the performance of the device can deteriorate. Therefore, the compound desiccates to have a melting point higher than the deposition temperature. The compound has a melting point, for example, at least about 10°C, for example, at least about 20°C, or at least about 30°C higher than the deposition temperature and is therefore desiccated.

[0771] More specifically, the donor-acceptor type material represented by chemical formula 1 can be described at the melting point (T) of the material. m Thermal decomposition occurs at the melting point (T) because... m ) and decomposition temperature (T) d The temperatures (sublimation temperature, deposition temperature, T) are similar. Therefore, if the temperature at which the film is formed by vacuum deposition (sublimation temperature, deposition temperature, T) is similar... s (Higher than T) m In this case, decomposition occurs more preferentially than sublimation (deposition), and therefore normal devices cannot be fabricated. Since it is impossible to fabricate stable image sensors using these materials, T... m It should be higher than T s And agreeably T m -T s ≥10℃.

[0772] Furthermore, during the fabrication of image sensors, a microlens array (MLA) needs to be formed after the fabrication of organic optoelectronic devices to concentrate light. This microlens array requires relatively high temperatures (greater than or equal to about 160°C, for example, greater than or equal to about 170°C, greater than or equal to about 180°C, or greater than or equal to about 190°C). It is required that the performance of the optoelectronic device (e.g., an organic optoelectronic device) does not deteriorate during these heat treatments. The performance degradation of the organic optoelectronic device during MLA heat treatment may not be due to the chemical decomposition of the organic material, but rather to morphological changes. When a material begins to thermally vibrate due to heat treatment, morphological changes are usually caused; however, materials with robust molecular structures may not exhibit thermal vibrations and are restricted and / or prevented from deteriorating through heat treatment. The compound can be suppressed from molecular thermal vibrations during MLA heat treatment due to the conjugated structure in the donor portion and thus can be stably maintained, ensuring process stability.

[0773] In the following description, with reference to the accompanying drawings, optoelectronic devices comprising the compound according to some exemplary embodiments are described.

[0774] Figure 1 A cross-sectional view of an optoelectronic device according to some exemplary embodiments is shown.

[0775] refer to Figure 1 An optoelectronic device 100 according to some exemplary embodiments includes: a first electrode 10 and a second electrode 20, and an active layer 30 between the first electrode 10 and the second electrode 20. The active layer 30 may include a composition according to any exemplary embodiment.

[0776] One of the first electrode 10 and the second electrode 20 is an anode and the other is a cathode. At least one of the first electrode 10 and the second electrode 20 may be a light-transmitting electrode, and the light-transmitting electrode may be made of, for example, a transparent conductor such as indium tin oxide (ITO) or indium zinc oxide (IZO), or a thin single-layer or multi-layer metal layer. When one of the first electrode 10 and the second electrode 20 is a non-light-transmitting electrode, it may be made of, for example, an opaque conductor such as aluminum (Al).

[0777] The active layer 30 includes p-type and n-type semiconductors to form a pn junction, and absorbs external light to generate excitons, which are then separated into holes and electrons.

[0778] The active layer 30 includes the composition for optoelectronic devices.

[0779] The active layer 30 may have a maximum absorption wavelength (λ) in a wavelength region greater than or equal to about 500 nm, for example greater than or equal to about 510 nm, greater than or equal to about 520 nm, greater than or equal to about 525 nm, greater than or equal to about 530 nm, or greater than or equal to about 535 nm and less than or equal to about 590 nm, for example less than or equal to about 580 nm, less than or equal to about 570 nm, or less than or equal to about 560 nm. 最大 ).

[0780] The active layer 30 can exhibit a relatively narrow half-width (FWHM) light absorption profile of about 50 nm to about 110 nm, for example, about 50 nm to about 100 nm. Therefore, the active layer 30 has high selectivity for light in the green wavelength region.

[0781] The active layer 30 can be a single layer or multiple layers. The active layer 30 can be, for example, an intrinsic layer (I layer), a p-type layer / I layer, an I layer / n-type layer, a p-type layer / I layer / n-type layer, a p-type layer / n-type layer, etc.

[0782] The intrinsic layer (I layer) may comprise a compound of Formula 1 and an n-type semiconductor compound in a ratio (volume ratio or thickness ratio) of approximately 1:100 to approximately 100:1. It may also comprise a compound of Formula 1 and an n-type semiconductor compound in a ratio of approximately 1:50 to approximately 50:1, particularly approximately 1:10 to approximately 10:1, and more particularly approximately 1:1. When the compound of Formula 1 and the n-type semiconductor compound have a composition ratio within the stated range, excitons can be effectively generated, and a pn junction can be effectively formed.

[0783] The p-type layer may include a semiconductor compound of Formula 1, and the n-type layer may include an n-type semiconductor compound.

[0784] The active layer 30 may have a thickness of about 1 nm to about 500 nm, and particularly about 5 nm to about 300 nm. When the active layer 30 has a thickness within the said range, the active layer can effectively absorb light, effectively separate holes from electrons, and transport them, thereby effectively improving photoelectric conversion efficiency. The desired thickness of the active layer 30 may be determined, for example, by the absorption coefficient of the active layer 30, and may be, for example, a thickness capable of absorbing at least about 70% or more, for example about 80% or more, and again for example about 90% or more of light.

[0785] In the optoelectronic device 100, excitons can be generated internally when light enters from the first electrode 10 and / or the second electrode 20, and when the active layer 30 absorbs light in a desired and / or alternatively predetermined wavelength region. The excitons are separated into holes and electrons in the active layer 30, and the separated holes are transported to the anode, which is one of the first electrode 10 and the second electrode 20, while the separated electrons are transported to the cathode, which is the other of the first electrode 10 and the second electrode 20, to allow current to flow in the optoelectronic device.

[0786] In the following text, refer to Figure 2 Describes optoelectronic devices based on some example implementations.

[0787] Figure 2 A cross-sectional view of an optoelectronic device according to some exemplary embodiments is shown.

[0788] refer to Figure 2 Like including Figure 1 Like some of the exemplary embodiments shown, the optoelectronic device 200 according to some exemplary embodiments includes: a first electrode 10 and a second electrode 20 facing each other, and an active layer 30 between the first electrode 10 and the second electrode 20.

[0789] However, unlike including Figure 1 Some of the exemplary embodiments shown in the illustration further include charge-assisted layers 40 and 45 between the first electrode 10 and the active layer 30, and between the second electrode 20 and the active layer 30. The charge-assisted layers 40 and 45 facilitate the transfer of holes and electrons separated from the active layer 30 to improve efficiency.

[0790] The charge-assisted layers 40 and 45 may be selected from at least one of the following: a hole injection layer (HIL) for promoting hole injection, a hole transport layer (HTL) for promoting hole transport, an electron blocking layer (EBL) for preventing electron transport, an electron injection layer (EIL) for promoting electron injection, an electron transport layer (ETL) for promoting electron transport, and a hole blocking layer (HBL) for preventing hole transport.

[0791] The charge-assisted layers 40 and 45 may comprise, for example, organic materials, inorganic materials, or organic / inorganic materials. The organic material may be an organic compound having hole or electron properties, and the inorganic material may be, for example, a metal oxide such as molybdenum oxide, tungsten oxide, nickel oxide, etc.

[0792] The hole transport layer (HTL) may include, for example, a selection from: poly(3,4-ethylenedioxythiophene):poly(sulfonated styrene) (PEDOT:PSS), polyarylamine (polyarylamine), poly(N-vinylcarbazole), polyaniline, polypyrrole, N,N,N',N'-tetra(4-methoxyphenyl)-benzidine (TPD), 4,4'-bis[N-(1-naphthyl)-N-phenyl-amino]biphenyl (α-NPD), m-MTDATA, 4,4',4”-tris(N-carbazolyl)-triphenylamine (TCTA), and combinations thereof, but is not limited thereto.

[0793] The electron blocking layer (EBL) may include, for example, a selection from: poly(3,4-ethylenedioxythiophene):poly(sulfonated styrene) (PEDOT:PSS), polyarylamine (polyarylamine), poly(N-vinylcarbazole), polyaniline, polypyrrole, N,N,N',N'-tetra(4-methoxyphenyl)-benzidine (TPD), 4,4'-bis[N-(1-naphthyl)-N-phenyl-amino]biphenyl (α-NPD), m-MTDATA, 4,4',4”-tris(N-carbazolyl)-triphenylamine (TCTA), and combinations thereof, but is not limited thereto.

[0794] The electron transport layer (ETL) may include, for example, one of the following: 1,4,5,8-naphthalene-tetracarboxylic acid dianhydride (NTCDA), copper bath (BCP), LiF, Alq3, Gaq3, Inq3, Znq2, Zn(BTZ)2, BeBq2, and combinations thereof, but is not limited thereto.

[0795] The hole blocking layer (HBL) may include, for example, one of the following: 1,4,5,8-naphthalene-tetracarboxylic acid dianhydride (NTCDA), copper bath (BCP), LiF, Alq3, Gaq3, Inq3, Znq2, Zn(BTZ)2, BeBq2, and combinations thereof, but is not limited thereto.

[0796] Either of the charge-assisted layers 40 and 45 may be omitted.

[0797] The aforementioned optoelectronic devices can be applied to a variety of fields, such as solar cells, image sensors, photodetectors, photoelectric sensors, and organic light-emitting diodes (OLEDs), but are not limited thereto.

[0798] Hereinafter, examples of image sensors including the organic optoelectronic device are described with reference to the accompanying drawings. An organic CMOS image sensor is described as an example of an image sensor.

[0799] Figure 3 To illustrate a schematic top view of an organic CMOS image sensor according to some exemplary embodiments, and Figure 4 To display Figure 3 A cross-sectional view of an organic CMOS image sensor.

[0800] refer to Figure 3 and 4 An organic CMOS image sensor 300 according to some exemplary embodiments includes a semiconductor substrate 310 integrating photosensing devices 50B and 50R, a transfer transistor (not shown), a charge memory 55, a lower insulating layer 60, a color filter layer 70, an upper insulating layer 80 (also referred to herein as an insulating layer), and an optoelectronic device 100. The optoelectronic device 100 may be an optoelectronic device according to any exemplary embodiment and is on the semiconductor substrate 310 (e.g., directly or indirectly thereon).

[0801] The semiconductor substrate 310 may be a silicon substrate and integrates a photosensor 50, a transfer transistor (not shown), and a charge storage device 55. The photosensor 50 may include photosensors 50R and 50B. Photosensors 50R and 50B may be photodiodes.

[0802] Light sensing devices 50B and 50R, a transfer transistor, and / or a charge memory 55 may be integrated in each pixel, and as shown in the figure, light sensing devices 50B and 50R may be included in the blue pixel and the red pixel, respectively, and the charge memory 55 may be included in the green pixel.

[0803] Light sensing devices 50B and 50R sense light, and the information sensed by the light sensing devices can be transmitted through the transmission transistor. Charge memory 55 is electrically connected to optoelectronic device 100, and the information in charge memory 55 can be transmitted through the transmission transistor.

[0804] In the figure, the light sensing devices 50B and 50R are arranged in parallel without limitation, for example, and the blue light sensing device 50B and the red light sensing device 50R can be stacked in the vertical direction.

[0805] Metal lines (not shown) and pads (not shown) are formed on the semiconductor substrate 310. To reduce signal delay, the metal lines and pads may be made of metals with low resistivity, such as aluminum (Al), copper (Cu), silver (Ag), and alloys thereof, but are not limited thereto. Furthermore, the structure is not limited to the described one, and the metal lines and pads may be positioned below the photosensitive devices 50B and 50R.

[0806] A lower insulating layer 60 is formed on the metal lines and pads. The lower insulating layer 60 may be made of inorganic insulating materials such as silicon oxide and / or silicon nitride, or low dielectric constant (low K) materials such as SiC, SiCOH, SiCO, and SiOF. The lower insulating layer 60 has trenches that expose the charge storage device 55. These trenches may be filled with filler.

[0807] A color filter layer 70 is formed on the lower insulating layer 60 and may be located between the optoelectronic device 100 and the semiconductor substrate 310. The color filter layer 70 includes a blue filter 70B formed in the blue pixels and configured to selectively transmit blue light, and a red filter 70R formed in the red pixels and configured to selectively transmit red light. In some embodiments, cyan and yellow filters may be provided instead of the blue filter 70B and the red filter 70R. In some embodiments, a green filter is not included, but may be further included.

[0808] The color filter layer 70 can be omitted. For example, when the blue light sensor 50B and the red light sensor 50R are stacked in the vertical direction, the blue light sensor 50B and the red light sensor 50R can selectively absorb light in each wavelength region depending on their stacking depth, and the color filter layer 70 may not be provided.

[0809] An upper insulating layer 80 is formed on the color filter layer 70. The upper insulating layer 80 eliminates the steps caused by the color filter layer 70 and smooths the surface. The upper insulating layer 80 and the lower insulating layer 60 may include contact holes (not shown) that expose pads and vias 85 that expose the charge memory 55 of the green pixels.

[0810] The aforementioned optoelectronic device 100 is formed on the upper insulating layer 80 (e.g., directly or indirectly thereon). The optoelectronic device 100 includes a first electrode 10, an active layer 30, and a second electrode 20, as described above.

[0811] The first electrode 10 and the second electrode 20 may be transparent electrodes, and the active layer 30 is the same as described above. The active layer 30 selectively absorbs and / or senses light in the green wavelength region and acts as a color filter for the green pixel. Therefore, the optoelectronic device 100 can be configured to selectively sense light in the green wavelength region.

[0812] When light enters from the second electrode 20, the light in the green wavelength region can be mainly absorbed in the active layer 30 and photoelectric converted, while the light in the other wavelength regions passes through the first electrode 10 and can be sensed in the photosensitive devices 50B and 50R.

[0813] As described above, optoelectronic devices that selectively absorb light in the green wavelength region are stacked, thereby reducing the size of the image sensor and enabling miniaturized image sensors.

[0814] As described above, the compound represented by Formula 1 can be used as a p-type semiconductor compound. In the thin film state, aggregation between compounds is suppressed, and thus the wavelength-dependent light absorption characteristics can be maintained. Consequently, green wavelength selectivity can be maintained, crosstalk caused by unwanted absorption of light outside the green wavelength region can be reduced, and sensitivity can be increased.

[0815] In some example implementations, in Figure 4 Further, additional color filters may be provided on the optoelectronic device 100. The additional color filters may include a blue filter 70B and a red filter 70R, or a cyan filter and a yellow filter.

[0816] An organic CMOS image sensor with a color filter disposed on the optoelectronic device is shown. Figure 5 middle.

[0817] Figure 5 A schematic cross-sectional view is shown to illustrate an organic CMOS image sensor according to some exemplary embodiments. References Figure 5 The organic CMOS image sensor 400 has the same characteristics as... Figure 4 The same structure exists, except that a color filter layer 72, including a blue filter 72B and a red filter 72R, is disposed on the optoelectronic device 100, such that the optoelectronic device 100 is located between the color filter layer 72 and the semiconductor substrate 310. Instead of the blue filter 72B and the red filter 72R, a cyan filter and a yellow filter may be disposed respectively.

[0818] exist Figure 4 and 5 Including Figure 1 The optoelectronic device 100 is not limited to this, and therefore can be applied in the same manner. Figure 2 200 optoelectronic devices.

[0819] Figure 6 A cross-sectional view of the organic CMOS image sensor 500 to which the optoelectronic device 200 is applied.

[0820] Figure 7 This is a schematic diagram illustrating an organic CMOS image sensor according to some exemplary embodiments.

[0821] refer to Figure 7 Like including Figure 5 As with some of the example embodiments shown, the organic CMOS image sensor 600 includes: a semiconductor substrate 310 integrating photosensitive devices 50B and 50R, a transport transistor (not shown), a charge memory 55, an insulating layer 80, and an optoelectronic device 100.

[0822] However, unlike including Figure 5 Some exemplary embodiments of the illustrated implementations show that the organic CMOS image sensor 600 includes a blue light sensor 50B and a red light sensor 50R and does not include a color filter layer 70. The blue light sensor 50B and the red light sensor 50R are stacked vertically in a semiconductor substrate 310 (e.g., perpendicular to the direction extending from the upper surface of the semiconductor substrate 310, such as...). Figure 7 (As shown in the diagram). For example, each of the multiple red light sensing devices 50R integrated in the semiconductor substrate 310 may be stacked vertically in the semiconductor substrate 310 with each of the multiple individual blue light sensing devices 50B. The blue light sensing devices 50B and the red light sensing devices 50R are electrically connected to a charge memory 55, and information from the charge memory 55 may be transmitted via the transfer transistor (not shown). The blue light sensing devices 50B and the red light sensing devices 50R may selectively absorb light in different wavelength regions depending on the stacking depth.

[0823] As described above, photoelectric devices that selectively absorb light in the green wavelength region are stacked, and the red light sensing device and the blue light sensing device are stacked, thereby reducing the size of the image sensor and enabling a miniaturized image sensor. As described above, the photoelectric device 100 has improved green wavelength selectivity, and crosstalk caused by unnecessary absorption of light in wavelength regions other than green is reduced, while increasing sensitivity.

[0824] exist Figure 7 Including Figure 1 The optoelectronic device 100 is not limited to this, and therefore can be applied in the same manner. Figure 2 200 optoelectronic devices.

[0825] Figure 8 This is a schematic diagram illustrating an organic CMOS image sensor according to some exemplary embodiments.

[0826] refer to Figure 8 An organic CMOS image sensor according to some exemplary embodiments includes a stacked green photoelectric device G that selectively absorbs light in a green wavelength region, a blue photoelectric device B that selectively absorbs light in a blue wavelength region, and a red photoelectric device R that selectively absorbs light in a red wavelength region. To reiterate, the organic CMOS image sensor may include a green photoelectric device configured to selectively sense light in a green wavelength region, a blue photoelectric device configured to selectively sense light in a blue wavelength region, and a red photoelectric device configured to selectively sense light in a red wavelength region, wherein the green, blue, and red photoelectric devices are stacked, such as at least... Figure 8 As shown in the image.

[0827] In the figure, the green optoelectronic device, the blue optoelectronic device, and the red optoelectronic device are stacked sequentially, but the stacking order can be changed without restriction.

[0828] The green optoelectronic device G may be the aforementioned optoelectronic device 100 or optoelectronic device 200, the blue optoelectronic device B may include electrodes facing each other and an active layer of organic material therebetween that selectively absorbs light in the blue wavelength region, and the red optoelectronic device R may include electrodes facing each other and an active layer of organic material therebetween that selectively absorbs light in the red wavelength region.

[0829] As described above, a green optoelectronic device G that selectively absorbs light in the green wavelength region, a blue optoelectronic device B that selectively absorbs light in the blue wavelength region, and a red optoelectronic device R that selectively absorbs light in the red wavelength region are stacked, thereby reducing the size of the image sensor and enabling a miniaturized image sensor.

[0830] The image sensor absorbs light in the appropriate wavelength range and can display the full improvement in sensitivity (YSNR10) and color reproducibility (ΔE*ab), regardless of the stacked structure.

[0831] Here, YSNR10 represents the sensitivity of an image sensor as measured by the method described in Juha Alakarhu's "Image Sensors and Image Quality in Mobile Phones" published in the 2007 International Image Sensor Workshop (Ogunquit Maine, USA), but expressed in lux as the minimum illumination at a signal-to-noise ratio of 10. Therefore, the smaller the YSNR10, the higher the sensitivity.

[0832] On the other hand, color reproducibility (ΔE*ab) shows the difference from the standard color in the X-Rite diagram, and ΔE*ab is defined as the distance between two points in the L*a*b* color space established by the CIE (Commission International de L'Eclairage) in 1976. For example, the color difference can be calculated according to Equation 1.

[0833] [Equation 1]

[0834]

[0835] In Equation 1,

[0836] ΔL* represents the change in chromaticity coordinate L* compared to the chromaticity coordinate L* at room temperature (approximately 20°C to approximately 25°C).

[0837] Δa* represents the change in chromaticity coordinate a* compared to its value at room temperature (approximately 20°C to 25°C).

[0838] Δb* represents the change in chromatic coordinate b* compared to the chromatic coordinate b* at room temperature (approximately 20°C to approximately 25°C).

[0839] To manufacture an image sensor with high sensitivity and high color reproducibility, YSNR10≤100 lux is required at ΔE*ab≤3. In this document, the compound is described as achieving a sensitivity of YSNR10≤100 lux and color reproducibility at ΔE*ab≤3.

[0840] The image sensor can be applied to a variety of electronic devices, such as mobile phones and digital cameras, but is not limited to these.

[0841] Figure 9 This is a block diagram of a digital camera including an image sensor, according to some example implementations.

[0842] refer to Figure 9 The digital camera 1000 includes a lens 1010, an image sensor 1020, a motor 1030, and an engine 1040. The image sensor 1020 can be used according to this application. Figure 3-8 One of the image sensors shown in the embodiment.

[0843] Lens 1010 focuses incident light onto image sensor 1020. Image sensor 1020 generates RGB data for the light received through lens 1010.

[0844] In some implementations, the image sensor 1020 may be coupled (interface) with the engine 1040.

[0845] The motor 1030 can adjust the focal length of the lens 1010 or execute the shutter in response to control signals received from the engine 1040. The engine 1040 can control the image sensor 1020 and the motor 1030.

[0846] Engine 1040 can be connected to host / application 1050.

(Reference) Figure 10Electronic device 1100 may include processor 1120, memory 1130, and image sensor 1140 electrically connected (coupled) together via bus 1110. Image sensor 1140 may be an image sensor according to one of the exemplary embodiments. Memory 1130 may be a non-transitory computer-readable medium and may store instruction programs. Memory 1130 may be non-volatile memory such as flash memory, phase-change random access memory (PRAM), magnetoresistive RAM (MRAM), resistive RAM (ReRAM), or ferroelectric RAM (FRAM), or volatile memory such as static RAM (SRAM), dynamic RAM (DRAM), or synchronous DRAM (SDRAM). Processor 1120 may execute the stored instruction programs to perform one or more functions. For example, processor 1120 may be configured to process electrical signals generated by image sensor 1140. Processor 1120 may include processing circuitry systems such as hardware including logic circuitry; hardware / software combinations such as a processor executing software; or combinations thereof. For example, the processing circuitry system may more specifically include, but is not limited to, a central processing unit (CPU), an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field-programmable gate array (FPGA), a system-on-a-chip (SoC), a programmable logic unit, a microprocessor, an application-specific integrated circuit (ASIC), etc. Processor 1120 may be configured to generate output (e.g., an image to be displayed on a display interface) based on such processing.

[0848] One or more of the processor 1120, memory 1130, motor 1030, engine 1040, or host / application 1050 may be included in, include, and / or implemented as: a processing circuit system, such as hardware including logic circuitry, a hardware / software combination, such as a processor executing software, or a combination thereof. In some exemplary embodiments, one or more of the processing circuit systems may include, but are not limited to, a central processing unit (CPU), application processor (AP), arithmetic logic unit (ALU), digital signal processor, microcomputer, field-programmable gate array (FPGA), system-on-a-chip (SoC), programmable logic unit, microprocessor, or application-specific integrated circuit (ASIC), etc. In some example implementations, any of the memory, memory cell, etc., as described herein may include a non-transitory computer-readable storage device such as a solid-state drive (SSD) that stores a program of instructions, and one or more of the processing circuitry systems may be configured to execute the instruction program to perform any or all of the functions of the processor 1120, memory 1130, motor 1030, engine 1040, or host / application 1050, etc., according to any example implementation described herein.

Here, the amount of charge in the next frame is referred to as the amount of residual charge.
