[0036] Reference will now be made in detail embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used in the drawings and the description to refer to the same or like parts.

[0037] Throughout the present disclosure and in the claims, certain words are used to connote physical significance. Fabricators of electronic devices can use different names to connote the same component. No attempt is made here to distinguish between components that can be alike in name but differ in function. Words used in the description and claims using the articles "a", "an" or "the" are intended to include both singular and plural forms and can therefore be read to cover both cases. Unless otherwise indicated, the word "comprising" is to be read to mean "consisting of" and the word "comprise" is to be read to mean "consist of".

[0038] Directional phrases used herein, such as, for example, "upper", "lower", "front", "back", "left", "right", and the like, are made only with reference to the positions of the figures as shown in the drawings. The directional phrases are used for purposes of illustration and are not meant to be limiting. In the figures, like reference numerals indicate particular elements throughout the several views. The figures are not drawn to scale, and the dimensions of each film layer, region, and / or structure can be exaggerated or minimized for the purpose of clarity.

[0039] As used herein, the term "on" or "over" with respect to a structure (or layer, component, substrate) being on or over another structure (or layer, component, substrate) means that the two structures are adjacent and directly connected, or that the two structures are adjacent but not directly connected. Not directly connected means that there is at least one intervening structure (or intervening layer, intervening component, intervening substrate, intervening spacing) between the two structures, with the underside surface of one structure being adjacent to or directly connected to the upper side surface of the intervening structure, and the upper side surface of the other structure being adjacent to or directly connected to the underside surface of the intervening structure. The intervening structure can be a single layer or multiple layers of solid or non-solid structures, without limitation. In the present disclosure, when a structure is disposed "on" another structure, it can mean that the structure is "directly" on the other structure, or that the structure is "indirectly" on the other structure, i.e., there is at least one structure between the structure and the other structure.

[0040] The terms "about", "equal", "equivalent", or "substantially" or "approximately" are generally interpreted to mean within 20% of the given value, or within 10%, 5%, 3%, 2%, 1%, or 0.5% of the given value.

[0041] The use of ordinal terms such as "first", "second", and the like in the description and the claims to modify a component does not inherently require that either or both of the components be the same; rather, the ordinal terms are used for purposes of clarity to distinguish one component from another. The use of the same ordinal term in the description and claims to refer to a component does not require that the component be the same in the description and the claims.

[0042] The electrical connection or coupling described in the present disclosure can refer to direct connection or indirect connection. In the case of direct connection, the terminals of two circuit components are directly connected or connected to each other by a conductor segment. In the case of indirect connection, there is a switch, a diode, a capacitor, an inductor, a resistor, other suitable components, or a combination of the above components between the terminals of two circuit components, but not limited thereto.

[0043] In the present disclosure, the measurement of thickness, length, and width can be obtained by optical microscopy, and the thickness or width can be measured by cross-sectional images in an electron microscope, but not limited thereto. In addition, there can be a certain error between any two values or directions used for comparison. In addition, the terms "equal to", "equal", "the same", "substantially", or "approximately" in the present disclosure generally represent a range of 10% of the given value or range. In addition, the phrase "a given range is a first value to a second value" or "a given range falls within a range of a first value to a second value" means that the given range includes the first value, the second value, and other values therebetween. If the first direction is perpendicular to the second direction, the angle between the first direction and the second direction can be between 80 degrees and 100 degrees; if the first direction is parallel to the second direction, the angle between the first direction and the second direction can be between 0 degrees and 10 degrees.

[0044] It should be understood that the following examples can be replaced, reorganized, mixed to complete other embodiments without departing from the spirit of the present disclosure. The features of each embodiment can be arbitrarily mixed and used as long as they do not conflict with the spirit of the invention or conflict.

[0045] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be understood that terms such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and should not be interpreted in an idealized or overly formal sense unless expressly so defined in the embodiments of the present disclosure.

[0046] In the present disclosure, the electronic device can include a display device, a backlight device, an antenna device, a sensing device, or a tiled device, but is not limited thereto. The electronic device can be a foldable or flexible electronic device. The display device can be a reflective liquid crystal display, an electronic paper, or a non-self-emissive display device, or a self-emissive display device. The antenna device can be a liquid crystal type antenna device or a non-liquid crystal type antenna device, and the sensing device can be a sensing device that senses capacitance, light, heat energy, or ultrasound, but is not limited thereto. The electronic component can include passive components and active components, such as a capacitor, a resistor, an inductor, a diode, a transistor, etc. The diode can include a light emitting diode or a photodiode. The light emitting diode can include, for example, an organic light emitting diode (OLED), a mini LED, a micro LED, or a quantum dot LED, but is not limited thereto. The tiled device can be, for example, a display tiled device or an antenna tiled device, but is not limited thereto. Note that the electronic device can be any arrangement combination of the foregoing, but is not limited thereto. Hereinafter, the display device will be described as the electronic device or the tiled device to explain the present disclosure, but the present disclosure is not limited thereto.

[0047] Figure 1 A schematic diagram of an electronic device 100 according to an embodiment of the present disclosure is shown in FIG. 1. As shown in FIG. 1, the electronic device 100 can include a display device 110, a backlight device 120, an antenna device 130, a sensing device 140, and a tiled device 150. Figure 1As shown, the electronic device 100 includes a gamma data source 102, a signal receiving circuit 104, a buffer circuit 106, a counter 108, a multitasker 110, gamma processing units 112-1, 112-2, …, 112-8, an output terminal 114, a source driver 116, a display panel 118, and a gate driver 120. The display panel 118 can be a reflective display panel or an e-paper display panel, but the present disclosure is not limited thereto. In some embodiments, the gamma data source 102 can include a matrix having M columns and N rows, where M and N are both natural numbers greater than 1. In some embodiments, M is 64 and N is 16, but the present disclosure is not limited thereto. In other words, in some embodiments, the gamma data source 102 can be a 64 by 16 matrix, but the present disclosure is not limited thereto. It should be noted that in the present disclosure, each row of the gamma data source 102 can correspond to a different gray scale value, and each row records a bit string corresponding to the gray scale value. Taking the gamma data source 102 with a 64 by 16 matrix (M = 64, N = 16) as an example, the gamma data source 102 can correspond to 16 different gray scale values (0th gray scale to 15th gray scale), and the bit string corresponding to each gray scale value includes a different number of bytes of 0s and 1s, and each bit in each bit string represents the voltage effect on a pixel in a short time. Therefore, a bit string represents the length of time the voltage effect is applied to a pixel in a specific display time. Taking a reflective liquid crystal display panel as an example, when the bit value is 0, it means that the pixel is subjected to a voltage, and the voltage effect will make the liquid crystal molecules deviate to the reflective state, so that the pixel can reflect external light and have a higher brightness. When the bit value is 1, it means that the pixel is subjected to another voltage, and the voltage effect will make the liquid crystal molecules rotate and deviate to the transmissive state, so that the pixel cannot reflect external light and has a lower brightness. Therefore, in the above-described gamma data source 102, the darkest 0th gray scale corresponds to a bit string in which all 64 bit values are equal to 1, which means that in the display time corresponding to the bit string, the pixel is always in the darker transmissive state. The brightest 15th gray scale corresponds to a bit string in which all 64 bit values are equal to 0, which means that in the display time corresponding to the bit string, the pixel is always in the brighter reflective state. In other words, the purpose of the gamma data source 102 is to convert the received gray scale values into a way to actually drive the pixels.

[0048] The signal receiving circuit 104 receives a source data 130 and correspondingly generates a set of gray scale values 132 to be transmitted to the buffer circuit 106. In some embodiments, the source data 130 can be any type of image data, and the gray scale values 132 can be presented in the form of bits having 0s and 1s, and correspond to integers greater than or equal to 0 and less than N. In some embodiments, the source data 130 can be a 24-bit RGB image, and the gray scale values 132 can be presented in the form of 8-bit RGB values. Figure 1In some embodiments of the present disclosure, the gray scale value 132 can correspond to 16 gray scale values (e.g., 0th gray scale to 15th gray scale represented by 4 bits "0000" to "1111" respectively), but the present disclosure is not limited thereto. The buffer circuit 106 can store the gray scale value 132. In Figure 1 In the illustrated embodiment, since the electronic device 100 includes 8 gamma processing units (e.g., gamma processing units 112-1, 112-2, …, 112-8) to process 8 pixels simultaneously, the gray scale values corresponding to the 8 pixels are sequentially stored in the buffer circuit 106. In other words, since the gray scale value corresponding to one pixel can be represented by 4 bits, 32 (equal to 4 times 8) bits of data associated with the gray scale values can be stored in the buffer circuit 106. Although Figure 1 Although the electronic device 100 includes 8 gamma processing units 112-1 to 112-8 in the illustrated embodiment, the number of gamma processing units is not limited in the present disclosure. In some embodiments, the gray scale value 132 is a gray scale value of a single color (e.g., red (R), green (G), blue (B)). Thus, in practical applications, the electronic device 100 can have 3 sets of gray scale values 132 to set the gray scale values of red (R), green (G), and blue (B) respectively, but the number of sets of gray scale values 132 is not limited in the present disclosure.

[0049] The counter 108 receives a system frequency signal 140 to generate a sequence number 142. In some embodiments, the sequence number is an integer greater than or equal to 0 and less than M. In Figure 1 In the illustrated embodiment, the counter 108 can represent 64 sequence numbers (M = 64) from 0 to 63, for example, by 6 bits, but the present disclosure is not limited thereto. The multiplexer 110 is coupled to the gamma data source 102 and the counter 108 to receive the sequence number 142 and output a bit information 150 corresponding to the sequence number 142 in the gamma data source 102. In some embodiments, the bit information 150 is a matrix having 1 column and N rows, and N is a natural number greater than 1. In Figure 1 In the illustrated embodiment, the bit information 150 can be a 1 by 16 matrix sequentially recording the bit value corresponding to each gray scale value in the bit information 150. For example, when the bit information 150 is [1 0 0 0 0 … 0] T , the bit value corresponding to the 0th gray scale is 1, the bit values corresponding to the 1st to 15th gray scales are all 0, and the rest follows the same pattern.

[0050] Table 1 is a schematic table showing the bit information 150 output by the multiplexer 110 corresponding to the sequence number 142 from the counter 108.

[0051]

[0052]

[0053] Table 1

[0054] As shown in Table 1, when the ordinal number 142 received by the multitasker 110 from the counter 108 is equal to 0, the multitasker 110 outputs the bit information 150 corresponding to the ordinal number 142 equal to 1 in the gamma data source 102, for example, [1 0 0 0 0 … 0] T . When the ordinal number 142 received by the multitasker 110 from the counter 108 is equal to 6, the multitasker 110 outputs the bit information 150 corresponding to the ordinal number 142 equal to 6 in the gamma data source 102, for example, [1 1 0 0 0 … 0] T . When the ordinal number 142 received by the multitasker 110 from the counter 108 is equal to 9, the multitasker 110 outputs the bit information 150 corresponding to the ordinal number 142 equal to 9 in the gamma data source 102, for example, [1 1 1 0 0 … 0] T . And so on. As mentioned above, since the bit values in the bit string corresponding to the brightest 15th gray scale are all 0, when the ordinal number 142 received by the multitasker 110 from the counter 108 is equal to 63, the multitasker 110 outputs the bit information 150 corresponding to the ordinal number 142 equal to 63 in the gamma data source 102, [1 1 1 1 1 … 1 0] T . The matrix content of Table 1 is only for illustration and is not a limitation of the present disclosure.

[0055] In the embodiment of Figure 1 , since the electronic device 100 includes 8 gamma processing units (for example, gamma processing units 112-1, 112-2, …, 112-8) to simultaneously process 8 pixels, the gray scale value 132 (a total of 32 bits) output by the buffer circuit 106 is branched into 8 paths to form gray scale values 132-1, 132-2, …, 132-8. In other words, the gray scale values 132-1 to 132-8 can each be represented by 4 bits. Taking the operation of the gamma processing unit 112-1 as an example, the gamma processing unit 112-1 receives the bit information 150 from the multitasker 110 and the gray scale value 132-1 from the buffer circuit 106, and outputs a bit value 160 corresponding to the gray scale value 132-1 in the bit information 150. For example, referring to Table 1, assuming that the bit information 150 output by the multitasker 110 is [1 1 0 0 0 … 0] T , and the gray scale value 132-1 output by the buffer circuit 106 corresponds to the 0th gray scale, the bit value 160 output by the gamma processing unit 112-1 is 1. Similarly, assuming that the bit information 150 output by the multitasker 110 is also [1 1 0 0 0 … 0] T , but the gray scale value 132-1 output by the buffer circuit 106 corresponds to the 4th gray scale, the bit value 160 output by the gamma processing unit 112-1 becomes 0.

[0056] Similarly, the gamma processing unit 112-2 receives the bit information 150 from the multiplexer 110 and the grayscale value 132-2 from the buffer circuit 106, and outputs a bit value 160-2 corresponding to the grayscale value 132-2 in the bit information 150, and so on. That is, the bit values 160, 160-2, …, 160-8 can all be represented by one bit. In some embodiments, the output terminal 114 is coupled to the gamma processing units 160, 160-2, …, 160-8 to receive the bit values 160, 160-2, …, 160-8 and output the bit values D1-D8, respectively. In Figure 1 In an embodiment, the bit value 160 is equal to the bit value D1, the bit value 160-2 is equal to the bit value D2, the bit value 160-3 is equal to the bit value D3, and so on. In the case that the gamma data source 102 is a 64-by-16 matrix, the gamma processing unit 160 must sequentially receive 64 pieces of bit information 150 from the multiplexer 110 and output 64 pieces of bit values 160, respectively, before completing the processing of the gamma data source 102.

[0057] The source driver 116 is coupled between the output terminal 114 and the display panel 118 to correspondingly generate a set of driving signals 170 according to the bit values D1-D8. The gate driver 120 is coupled to the display panel 118 to output an enabling signal 180 to the display panel 118, so that the display panel 118 can receive the driving signals 170 and display luminance corresponding to the grayscale values (e.g., the grayscale values 132-1-132-8) according to the driving signals 170. For example, the display panel 118 includes a first direction (e.g., the X direction) and a second direction (e.g., the Y direction). The driving signals 170 output by the source driver 116 are used to drive a plurality of pixels arranged along one of the first direction and the second direction in the display panel 118 along the same direction. The gate driver 120 outputs the enabling signal 180 to the display panel 118, so that the first row of pixels can display luminance corresponding to the grayscale values (e.g., the grayscale values 132-1-132-8). Generally, the content of the gamma data source 102 can be a default value and can be adjusted manually according to actual needs. In some embodiments, Figure 1 The gamma data source 102, the signal receiving circuit 104, the buffer circuit 106, the counter 108, the multiplexer 110, the gamma processing units 112-1, 112-2, …, 112-8, and the output terminal 114 are located in a timing control (TCON) circuit, but the present disclosure is not limited thereto. Figure 1The electronic device 100, through the pre-selection of the multiplexer 110 and the counter 108, enables the gamma processing unit 112-1 to receive bit information 150 without having to receive all the data in the gamma data source 102, which can greatly save the storage space required by the gamma processing unit 112-1.

[0058] Figure 1 This is a schematic diagram of an electronic device 200 according to an embodiment of the present disclosure. As can be seen from the foregoing description, Figure 2 The gamma data source 102 contains multiple bit strings, and in each bit string, the number of bits with a value of 0 is not necessarily the same as the number of bits with a value of 1. Therefore... Figure 1 Electronic devices 200 and Figure 2 The biggest difference of the electronic device 100 is that, Figure 1 The gamma data source 202 only records the number of bits with a value of 0 and / or a value of 1 for each grayscale value. It does not record the number of bits with a value of 0 for each grayscale value. Figure 2 The gamma data source 102 contains a raw, complete bit string composed of multiple 0s and 1s. For example, in the previous embodiment, in Figure 1 The gamma data source 102 corresponds to the bit string of the 0th gray level in [1,1,1…,1]. T It means that, while Figure 1 The gamma data source 202 records that there are 0 bits with a value of 0 and / or 64 bits with a value of 1 for the corresponding gray level 0. That's all. However, the recording method of the gamma data source 202 in this disclosure is not limited to this. In other words, in some embodiments, the gamma data source 202 may contain a 7x16 matrix, where the "16" refers to 16 gray levels, and the "7" represents the number of bits with a value of 0 or 1 for a specific gray level recorded in a shorter bit string format (for example, "0000001" represents 1 bit with a value of 1, "0100000" represents 32 bits with a value of 1, and so on). Since the gamma data source 102 is a 64-bit * 16-bit matrix, the data in a row of the matrix may have 0 ones (corresponding to the highest brightness), 1 one, 2 ones, ..., 64 ones, etc., a total of 65 variations. Therefore, counter 108 uses a conversion parameter containing 7 bits (there are 128 variations in total, but only 65 of them are used to represent the 65 brightness variations) to fully represent the aforementioned 65 variations. However, this disclosure is not limited thereto.

[0059] Generally speaking, taking the gamma processing unit 112-1 as an example, the driving signal 170 outputted by the source driver 116 is associated with the accumulation of the 64-bit values 160 sequentially outputted by the gamma processing unit 112-1. In some embodiments, the higher the accumulated value of the 64-bit values 160 sequentially outputted by the gamma processing unit 112-1, the longer the driving signal 170 outputted by the source driver 116 is at a high voltage. It should be noted that if the display panel 118 is a reflective panel or an electronic paper display panel, a longer time of high voltage will make the pixels of the display panel 118 tend to be in a light-transmitting state for a longer time, and the reflective state capable of reflecting light for a shorter time, so the display brightness is lower. Conversely, a longer time of low voltage will make the pixels of the display panel 118 tend to be in a light-transmitting state for a shorter time, and the reflective state capable of reflecting light for a longer time, so the display brightness is higher. The gamma data source 102 of Figure 2 Converting the gamma data source 102 into the gamma data source 202 is a technical effect that can achieve storage space saving. Conversely, the decoder 204 is coupled to the gamma data source 202, wherein the decoder 204 can include a conversion table to convert the data in the gamma data source 202 to obtain a conversion result, so that the multiplexer 110 can output the bit information 150 corresponding to the ordinal number 142 of the counter 108 from the conversion result.

[0060] Table II is a schematic table showing that the decoder 204 and the multiplexer 110 output different bit information 150 corresponding to the ordinal number 142 from the counter 108.

[0061]

[0062] Table II

[0063] As shown in Table II, when the ordinal number 142 from the counter 108 is equal to 0, the gamma data source 202 receives the ordinal number and provides corresponding data to the decoder 204 according to the ordinal number, and the decoder 204 converts the data from the gamma data source 202 to obtain a conversion result, so that the multiplexer 110 can select and output the bit information 150 corresponding to the ordinal number 142 of 0 from the conversion result, for example, [1 0 0 0 0 … 0] T When the ordinal number 142 of the counter 108 is equal to 6, the decoder 204 converts the gamma data source 202 according to the conversion table, so that the multiplexer 110 can select and output the bit information 150 corresponding to the ordinal number 142 of 6 from the conversion result, for example, [1 1 0 0 0 … 0] T . The rest can be analogized. The matrix content of Table II is exemplary and is not a limitation of the present disclosure. In Figure 1 In embodiments, the operations of other components of the electronic device 200 are the same as those of the electronic device 100, and thus will not be described again.

[0064] Figure 2 Embodiments of this disclosure Figure 3 Electronic device 100 and Figure 1 A schematic diagram of the buffer circuit 106 of the electronic device 200 storing grayscale values ​​132. (See diagram below.) Figure 2 Figure 3 As shown, after the buffer circuit 106 receives the grayscale value 132 from the signal receiving circuit 104, since the electronic devices 100 and 200 include eight gamma processing units (e.g., gamma processing units 112-1, 112-2, ..., 112-8) to process eight pixels simultaneously, the buffer circuit 106 sequentially stores the grayscale values ​​corresponding to the eight pixels in an address addr. For example, the buffer circuit 106 stores the grayscale value 132-1 of gamma processing unit 112-1 in a storage space DAT_7 in the address addr, stores the grayscale value 132-2 of gamma processing unit 112-2 in a storage space DAT_6 in the address addr, stores the grayscale value 132-3 of gamma processing unit 112-3 in a storage space DAT_5 in the address addr, and so on. In some embodiments, the size of storage spaces DAT_7 to DAT_0 may all be 4 bits, but this disclosure is not limited thereto.

[0065] While embodiments of this disclosure are as described above, it should be understood that what is presented above is merely exemplary and not limiting. Many modifications to the exemplary embodiments described above can be made without departing from the spirit and scope of the disclosure. Therefore, the breadth and scope of this disclosure should not be limited by the embodiments described above. Rather, the scope of this disclosure should be defined by the following claims and their equivalents.
