Description

Electronic device for afterimage compensation, display device and method of operation thereof

[0001] The present disclosure relates to an electronic device for afterimage compensation, a display device, and a method of operating the same.

[0002] Due to advancements in display technology, various types of display devices are being widely used in many fields. As an example, electronic paper display devices, which operate at low power and provide visibility similar to paper, are being used in various fields. Since electronic paper displays consume little power and offer excellent readability, they can be used to display images for extended periods. For instance, electronic paper displays can be used to display price tags or product information in supermarkets or stores.

[0003] The information described above may be provided as related art for the purpose of aiding understanding of this document. None of the foregoing is to be claimed as prior art related to this document, nor is it to be used to determine prior art.

[0004] Afterimages can occur in display devices based on electrical characteristics and image refresh methods. Afterimages refer to a phenomenon where parts of a previously displayed image remain even after a screen transition or image refresh. For example, in e-paper displays, afterimages can occur if electrically activated particles are not completely rearranged, preventing the previous image from fading away. Since e-paper displays can maintain images displayed on the screen even without a power supply, afterimages are a more noticeable issue.

[0082] Hereinafter, with reference to FIGS. 4a to 4e, an afterimage compensation operation performed in a display system (100) will be described as an example. According to one embodiment, the operations shown in FIGS. 4a to 4e can be performed sequentially.

[0083] FIG. 4a is a drawing illustrating a residual image screen displayed on a display device according to one embodiment.

[0084] Referring to (a) of FIG. 4a, the display device (110) can display a first image (402) on the display (220). For example, the first image (402) may include an image stored in the display device (110), or an image received from an electronic device (120) or a source device (130).

[0085] According to one embodiment, the display device (110) may stop displaying the first image (402) based on an external input (e.g., user input), the occurrence of an event (e.g., the elapsed time of displaying the first image (402)), or the receipt of a new image from the source device (130).

[0086] Referring to (b) of FIG. 4a, the display device (110) may perform a screen switching or image update operation based on stopping the display of the first image (402). For example, the display device (110) may display a second image (404) based on stopping the display of the first image (402). For example, the second image (404) may include an image stored in the display device (110), or an image received from an electronic device (120) or a source device (130), and may be an image displayed after the first image (402).

[0087] According to one embodiment, an afterimage may occur as the image displayed on the display device (110) changes. The afterimage may represent a phenomenon in which a part of the previous image (e.g., the first image (402)) remains faintly visible after the screen of the display device (110) is updated and appears superimposed on the newly displayed image (e.g., the second image (404)). The afterimage may also be referred to as a sticky phenomenon. For example, the afterimage may occur when a trace of the previously displayed '9' remains at the position of the first displayed '0' from the left in the second image (404).

[0088] According to one embodiment, if the display device (110) is an e-paper device, electronic ink particles (e.g., black and white particles and / or color particles) may need to be moved to a position corresponding to a new image for screen updating or display image updating. The electronic ink particles may be used for display operations of the display device (110). For example, the electronic ink particles may be included in the display (220) and may perform various display operations based on position or arrangement information corresponding to electrical characteristics (e.g., per-pixel voltage value).

[0089] According to one embodiment, if at least some of the electronic ink particles do not move to a position corresponding to a new image, an afterimage may occur. For example, if the voltage applied to each pixel for image updating is not appropriate or if the electronic ink particles do not respond to the applied voltage, the electronic ink particles may not move from the position of the previous image, and an afterimage may occur.

[0090] According to one embodiment, the display device (110) may perform a residual image compensation operation to reduce or eliminate residual images. For example, the residual image compensation operation may include a refresh operation or a voltage compensation operation for the area where residual images occur.

[0091] According to one embodiment, the refresh operation may include applying a voltage corresponding to a set color (e.g., white or black) to the entire or part of the screen of the display device (110) to initialize or move electronic ink particles contained in the entire or part of the screen of the display device (110). The refresh operation may be performed repeatedly or for a set period of time. When the refresh operation is performed, the electronic ink particles used for the previous image may be moved to an initialized position that is not displayed on the display (220). Thus, the new image may be displayed without afterimage.

[0092] According to one embodiment, the electronic device (120) can perform the following operations for the afterimage compensation operation of the display device (110).

[0093] FIG. 4b is a diagram illustrating the operation of an electronic device identifying an original image according to one embodiment.

[0094] Referring to FIG. 4b, the electronic device (120) can identify the original image (406). According to one embodiment, the electronic device (120) can identify the original image (406) obtained from the display device (110) or the source device (130), or identify the original image (406) stored in the electronic device (120). The original image (406) may be, for example, the original image for the second image (404) of FIG. 4a.

[0095] According to one embodiment, an electronic device (120) may request an original image (406) from a source device (130) or a display device (110) based on an external input (e.g., user input) or a second application, and receive the original image (406) from the source device (130) or the display device (110) in response to the request.

[0097] Referring to FIG. 4c, the electronic device (120) can capture a second image (404) displayed on the display device (110) through the camera (310). The electronic device (120) can detect an area corresponding to the screen of the display device (110) in the captured image and obtain a captured image (408).

[0098] FIG. 4d is a diagram illustrating the operation of an electronic device according to one embodiment generating information for afterimage compensation.

[0099] Referring to FIG. 4d, the electronic device (120) can compare the original image (406) received from the source device (130) in FIG. 4b with the captured image (408) acquired in FIG. 4c. For example, the electronic device (120) can compare the original image (406) and the captured image (408) based on an open source library for computer vision or image processing operations. Based on the comparison result, the electronic device (120) can identify an area with image differences in the captured image (408). Based on the fact that the area with image differences contains an afterimage, the electronic device (120) can identify the identified area as an afterimage area (410).

[0100] According to one embodiment, the electronic device (120) can identify the degree of afterimage (or afterimage residual ratio, afterimage intensity, or afterimage level) within the afterimage region (410) based on image difference. The electronic device (120) can generate afterimage compensation information based on the degree of afterimage within the afterimage region (410).

[0101] According to one embodiment, the afterimage compensation information may include at least one of a voltage value to be applied to the afterimage area (410) or a voltage compensation value to be applied to the afterimage area (410), time information indicating the time for which the voltage value is applied to the afterimage area (410), or number information indicating the number of times the voltage value is applied to the afterimage area (410).

[0102] According to one embodiment, afterimage compensation information may be used for a refresh operation for an afterimage area (410). For example, a voltage value or a voltage compensation value may be used to determine a voltage value to be applied to each pixel of the afterimage area (410) for a refresh operation, time information may be used to determine the time for performing a refresh for the afterimage area (410), and number information may be used to determine the number of refresh operations (or number of repetitions) for the afterimage area (410).

[0105] According to one embodiment, the display device (110) may perform an afterimage compensation operation (414) for a displayed second image (404) based on information regarding an afterimage area (410) and afterimage compensation information. For example, the afterimage compensation operation (414) may include an operation to adjust the voltage value of each pixel within the afterimage area (410) based on a voltage value or a voltage compensation value, or a refresh operation for the afterimage area (410).

[0106] According to one embodiment, the display device (110) can display a second image (416) in which the afterimage is reduced or removed based on an afterimage compensation operation (414).

[0107] FIG. 5 is a diagram illustrating the operation of an electronic device according to one embodiment generating afterimage compensation information based on the degree of afterimage.

[0108] According to one embodiment, the electronic device (120) can identify the degree of afterimage within the afterimage area (410) of FIG. 4d. For example, the degree of afterimage represents the degree or intensity of afterimage display, and may be a numerical value representing the intensity of afterimage display based on the degree of afterimage (e.g., 0%) of the corresponding area (or area without afterimage) within the original image (406). For example, the closer the degree of afterimage is to a set value (e.g., 100%), the higher the intensity of afterimage display may be, and the closer the degree of afterimage is to a reference value (e.g., 0%), the lower the intensity of afterimage display may be.

[0109] According to one embodiment, the electronic device (120) may determine or change the refresh execution time (or the time during which a voltage value is applied to the afterimage area), the number of refresh operations (or the number of times a voltage value is applied to the afterimage area), or the voltage value for the refresh based on the degree of afterimage.

[0110] For example, the afterimage region (502) illustrated in FIG. 5(a) may include an afterimage with an afterimage degree of 15%. Based on the afterimage degree of 15%, the electronic device (120) may increase the refresh execution time by a factor of A (e.g., 5 times) relative to the set execution time, increase the number of refresh operations by a factor of B (e.g., 5 times), or increase the voltage value for the refresh by a first voltage compensation value (e.g., 0.5V) relative to the set voltage value. A and B may be positive real numbers greater than or equal to 1 (e.g., positive integers or positive decimals), and may be the same or different.

[0111] For example, the afterimage region (504) illustrated in FIG. 5(b) may contain an afterimage with an afterimage degree of 35%. Based on the afterimage degree of 35%, the electronic device (120) may increase the refresh execution time by a factor of C (e.g., 8 times) relative to the set execution time, increase the number of refresh operations by D (e.g., 8 times), or increase the voltage value for the refresh by a second voltage compensation value (e.g., 1.0 V) relative to the set voltage value. C and D may each be positive real numbers greater than A and B, and may be the same or different.

[0112] For example, the afterimage region (506) illustrated in FIG. 5 (c) may contain an afterimage with an afterimage degree of 50%. Based on the afterimage degree of 50%, the electronic device (120) may increase the refresh execution time by a factor of E (e.g., 10 times) relative to the set execution time, increase the number of refresh operations by a factor of F (e.g., 10 times), or increase the voltage value for the refresh by a third voltage compensation value (e.g., 2.0V) relative to the set voltage value. E and F may each be positive real numbers greater than C and D, and may be the same or different.

[0113] For example, the afterimage region (508) illustrated in FIG. 5 (d) may contain an afterimage with an afterimage degree of 85%. Based on the afterimage degree of 85%, the electronic device (120) may increase the refresh execution time by G times (e.g., 15 times) relative to the set execution time, increase the number of refresh operations by H times (e.g., 15 times), or increase the voltage value for the refresh by a fourth voltage compensation value (e.g., 5.0 V) relative to the set voltage value. G and H may be positive real numbers greater than E and F, respectively, and may be the same or different.

[0114] As described with reference to FIG. 5 (a) to (d), the electronic device (120) can increase the refresh execution time longer, increase the number of refresh operations more, or increase the voltage value or voltage compensation value for the refresh to a larger value as the degree of afterimage increases.

[0115] According to one embodiment, the electronic device (120) can generate afterimage compensation information for the display device (110) based on at least one of information determined based on the degree of afterimage, for example, the number of refresh operations, the refresh execution time, or a voltage value or a voltage compensation value for the refresh. The electronic device (120) can transmit the generated afterimage compensation information to the display device (110).

[0116] According to one embodiment, the display device (110) can perform a refresh operation on the afterimage area based on afterimage compensation information generated by the electronic device (120).

For example, the display device (120) can identify pixels where the difference from the voltage value falls outside a predetermined range (e.g., pixels with a voltage value of 6V) as pixels requiring afterimage compensation.

[0123] Referring to FIG. 6(c), the display device (110) can determine a voltage compensation value (630) for each pixel requiring afterimage compensation based on a set voltage value (610) and a measured voltage value (620).
