[0046] Please refer toFigure 1 , Figure 1 is a schematic diagram of an electronic device shown in the first embodiment of the present disclosure. In this embodiment, the electronic device 100 includes a substrate SB, electronic units EU11 to EUmn, a data driver 110, and multiple pairs of data lines LDP1 to LDPm. In this embodiment, the substrate SB has an active area AA. The electronic units EU11 to EUmn are arranged in an array in the active area AA. For example, the electronic units EU11 to EUmn are arranged in an n-row and m-column array. The electronic units EU11, EU21,..., EUm1 are the electronic units in the first row. The electronic units EU12, EU22,..., EUm2 are the electronic units in the second row. Similarly, the electronic units EU1n, EU2n,..., EUmn are the electronic units in the nth row. The electronic units EU11, EU12,..., EU1n are the electronic units in the first column. The electronic units EU21, EU22,..., EU2n are the electronic units in the second column. Similarly, the electronic units EUm1, EUm2,..., EUmn are the electronic units in the mth column.
[0047] In this embodiment, each of the electronic units EU11 to EUmn includes a microcontroller and multiple electronic components. For example, the electronic unit EU11 includes a microcontroller UIC11 and electronic components E11_1, E11_2, E11_3. In the electronic unit EU11, the microcontroller UIC11 is electrically connected to the electronic components E11_1, E11_2, E11_3. In the electronic unit EU21, the microcontroller UIC21 is electrically connected to the electronic components E21_1, E21_2, E21_3. Similarly, the remaining electronic units have similar implementation manners.
[0048] In this embodiment, the data driver 110 is disposed on the substrate SB. The data driver 110 can be disposed outside the active area AA (such as the peripheral area), but the present disclosure is not limited thereto. The data driver 110 provides differential signals DS1 to DSm. The multiple pairs of data lines LDP1 to LDPm are respectively coupled to the data driver 110 and the corresponding multiple microcontrollers. The multiple pairs of data lines LDP1 to LDPm transmit the differential signals DS1 to DSm to the corresponding multiple microcontrollers. For example, a pair of data lines LDP1 is coupled to the data driver 110 and the multiple microcontrollers of the electronic units EU11, EU12,..., EU1n. A pair of data lines LDP2 is coupled to the data driver 110 and the multiple microcontrollers of the electronic units EU21, EU22,..., EU2n. Similarly, a pair of data lines LDPm is coupled to the data driver 110 and the multiple microcontrollers of the electronic units EUm1, EUm2,..., EUmn.
[0049] Taking the microcontroller UIC11 as an example, the microcontroller UIC11 receives the differential signal DS1, generates drive signals S1 to S3 according to the differential signal DS1, and inputs the drive signals S1 to S3 to the electronic components E11_1, E11_2, and E11_3 respectively. For example, the microcontroller UIC11 inputs the drive signal S1 to the electronic component E11_1, inputs the drive signal S2 to the electronic component E11_2, and inputs the drive signal S3 to the electronic component E11_3.
[0050] It is worth mentioning here that the differential signal DS1 can reduce signal interference and electromagnetic interference. The microcontroller UIC11 can generate drive signals S1 to S3 according to the differential signal DS1. Therefore, the electronic device 100 can reduce signal interference and electromagnetic interference and operate correctly.
[0051] Taking the microcontroller UIC11 as an example again, the microcontroller UIC11 can decode the differential signal DS1, and the differential signal DS1 is a clock embedded differential signal or a scrambled differential signal. In other words, the electronic unit EU11 can be applied to different predefined types of differential signals DS1.
[0052] In this embodiment, the electronic units EU11 to EUmn each include 3 electronic components as an example, but the disclosure is not limited to the number of electronic components, and the number of electronic components of the electronic units EU11 to EUmn can be multiple. In some embodiments, the number of electronic components of the electronic units EU11 to EUmn may not be exactly the same.
[0053] In this embodiment, the electronic device 100 can be a display device. The electronic units EU11 to EUmn are pixel units respectively. The multiple electronic components in the electronic units EU11 to EUmn can be any form of liquid crystal elements, light emitting diodes or other light emitting elements respectively. Therefore, the drive signals (such as drive signals S1 to S3) for driving the electronic components can be current signals or pulse-width modulation (PWM) signals respectively.
[0054] In some embodiments, the electronic device 100 can be an antenna device or a modulation device. The electronic units EU11 to EUmn are modulation units respectively. The multiple electronic components in the electronic units EU11 to EUmn can be varactors, variable capacitors or variable resistors in any form respectively.
[0055] In this embodiment, the substrate SB can be a rigid substrate or a flexible substrate. For example, the rigid substrate can be a glass substrate or a silicon substrate, and the flexible substrate can be a plastic substrate or a polymer substrate, but the disclosure is not limited thereto.
[0056] In this embodiment, a pair of data lines LDP1 includes a first data line and a second data line (not shown). The differential signal DS1 is equal to the differential result between the signal on the first data line and the signal on the second data line. Therefore, the differential signal DS1 can reduce signal interference and electromagnetic interference.
[0057] In this embodiment, the electronic device 100 further includes a gate driver 120 and scan lines LS1 to LSn. The scan lines LS1 to LSn are electrically connected to the gate driver 120 and corresponding multiple microcontrollers. The gate driver 120 transmits gate signals GS1 to GSn to the multiple microcontrollers through the scan lines LS1 to LSn respectively. For example, the scan line LS1 is coupled to the gate driver 120 and multiple microcontrollers of the electronic units EU11, EU21, …, EUm1. The scan line LS2 is coupled to the gate driver 120 and multiple microcontrollers of the electronic units EU12, EU22, …, EUm2. Similarly, the scan line LSn is coupled to the data driver 110 and multiple microcontrollers of the electronic units EU1n, EU2n, …, EUmn. Therefore, the gate driver 120 provides the gate signal GS1 to the multiple microcontrollers of the electronic units EU11 to EUm1. The gate driver 120 provides the gate signal GS2 to the multiple microcontrollers of the electronic units EU12 to EUm2, and so on.
[0058] In this embodiment, the gate driver 120 is disposed on the substrate SB, but the disclosure is not limited thereto. The gate driver 120 can be disposed outside the active area AA (such as the peripheral area), but the disclosure is not limited thereto.
[0059] Please also refer to Figure 1 and Figure 2 , Figure 2 is a signal timing diagram shown according to the first embodiment of the present disclosure. Figure 2 Shows the differential signals DS1 to DSm. In this embodiment, based on the timing of the gate signals GS1 to GSn, the electronic units EU11 to EUmn are selected in a row-by-row order.
[0060] During the sub-period Pn of the operation period TD1, the electronic units EU1n, EU2n, …, EUmn of the n-th row are selected. The differential signal DS1 has data DD1(n) during the sub-period Pn of the operation period TD1. The differential signal DS2 has data DD2(n) during the sub-period Pn of the operation period TD1. The differential signal DSm has data DDm(n) during the sub-period Pn of the operation period TD1. Therefore, the electronic unit EU1n drives a plurality of electronic components in the electronic unit EU1n according to the data DD1(n). The electronic unit EU2n drives a plurality of electronic components in the electronic unit EU2n according to the data DD2(n). The electronic unit EUmn drives a plurality of electronic components in the electronic unit EUmn according to the data DDm(n).
[0061] During the blanking period BLK after the sub-period Pn of the operation period TD1, the differential signals DS1 to DSm respectively have blanking data (not shown). During the blanking period BLK, the electronic units EU11 to EUmn do not update the state during the operation period TD1.
[0062] After the blanking period BLK, after a delay time length tl1, the differential signals DS1 to DSm respectively have a start signal ST. Subsequently, the operation period TD2 starts.
[0063] During the sub-period P1 of the operation period TD2, the electronic units EU11, EU21, …, EUm1 of the first row are selected. The differential signal DS1 has data DD1(1) during the sub-period P1 of the operation period TD2. The differential signal DS2 has data DD2(1) during the sub-period P1 of the operation period TD2. The differential signal DSm has data DDm(1) during the sub-period P1 of the operation period TD2. Therefore, the electronic unit EU11 outputs drive signals S1 to S3 to the electronic components E11_1 to E11_3 respectively according to the data DD1(1), thereby driving the electronic components E11_1 to E11_3. The electronic unit EU21 drives the electronic components E21_1 to E21_3 according to the data DD2(1). The electronic unit EUm1 drives a plurality of electronic components in the electronic unit EUm1 according to the data DDm(1).
[0064] After a sub-period P1 of TD2 during operation, after a delay time length tl2, the electronic units EU12, EU22, …, EUm2 of the second row are selected during a sub-period P2 of TD2 during operation. The differential signal DS1 has data DD1(2) during the sub-period P2 of TD2 during operation. The differential signal DS2 has data DD2(2) during the sub-period P2 of TD2 during operation. The differential signal DSm has data DDm(2) during the sub-period P2 of TD2 during operation. Accordingly, the electronic unit EU12 drives a plurality of electronic components in the electronic unit EU12 according to the data DD1(2). The electronic unit EU22 drives a plurality of electronic components in the electronic unit EU22 according to the data DD2(2). The electronic unit EUm2 drives a plurality of electronic components in the electronic unit EUm2 according to the data DDm(2).
[0065] In this embodiment, the delay time lengths tl1 and tl2 can be adjusted. In some embodiments, at least one of the delay time lengths tl1 and td2 can be omitted.
[0066] Please refer to Figure 3 , Figure 3 which is a schematic diagram of an electronic device shown in the second embodiment of the present disclosure. In this embodiment, the electronic device 200 includes a substrate SB, electronic units EU11~EUmn, a data driver 110, and multiple pairs of data lines LDP1~LDPm. In this embodiment, the substrate SB has an active area AA. The electronic units EU11~EUmn are arranged in an array in the active area AA. The arrangement manners among the electronic units EU11~EUmn, the data driver 110, and the multiple pairs of data lines LDP1~LDPm have been clearly described in the embodiment of Figure 1 and thus will not be repeated here.
[0067] The electronic units EU11~EUmn are selected in a row-by-row order. In this embodiment, the electronic units EU11, EU21, …, EUm1 located in the first row receive a high-level signal SH and then operate. Accordingly, the microcontrollers of the electronic units EU11, EU21, …, EUm1 (i.e., the first row microcontrollers) start to receive the differential signals DS1~DSm. When the differential signals DS1~DSm received by the microcontrollers of the electronic units EU11, EU21, …, EUm1 include a start protocol, the microcontrollers of the electronic units EU11, EU21, …, EUm1 output drive signals to the corresponding multiple electronic components. In addition, the microcontrollers of the electronic units EU11, EU21, …, EUm1 also respectively output scan signals SS12, SS22, …, SSm2 to the electronic units EU12, EU22, …, EUm2 of the next row.
[0068] Taking the electronic units EU11 and EU12 as an example, the electronic unit EU11 operates when it receives a high-level signal SH. The microcontroller UIC11 receives the differential signal DS1. When the microcontroller UIC11 receives the start protocol in the differential signals DS1 to DSm, the microcontroller UIC11 generates drive signals S1 to S3 according to the differential signal DS1, and inputs the drive signals S1 to S3 to the electronic components E11_1, E11_2, and E11_3 respectively. In addition, the microcontroller UIC11 also generates a scan signal SS12 and provides the scan signal SS12 to the electronic unit EU12.
[0069] The electronic unit EU12 operates when it receives the scan signal SS12. The microcontroller of the electronic unit EU12 generates drive signals S1 to S3 according to the differential signal DS1, and inputs the drive signals S1 to S3 to a plurality of electronic components in the electronic unit EU12 respectively. The electronic unit EU12 generates a scan signal SS13 according to the scan signal SS12 and provides the scan signal SS13 to the electronic unit in the next row.
[0070] Please also refer to Figure 3 、 Figure 4 and Figure 5 , Figure 4 and Figure 5 which are respectively the signal timing diagrams shown according to the second embodiment of the present disclosure. In this embodiment, during the sub-period Pn of the operation period TD1, the electronic units EU1n, EU2n,..., EUmn of the nth row operate according to the scan signals SS1n, SS2n,..., SSmn. The differential signal DS1 has data DD1(n) during the sub-period Pn of the operation period TD1. The differential signal DS2 has data DD2(n) during the sub-period Pn of the operation period TD1. The differential signal DSm has data DDm(n) during the sub-period Pn of the operation period TD1. Therefore, the electronic unit EU1n drives a plurality of electronic components in the electronic unit EU1n according to the data DD1(n). The electronic unit EU2n drives a plurality of electronic components in the electronic unit EU2n according to the data DD2(n). The electronic unit EUmn drives a plurality of electronic components in the electronic unit EUmn according to the data DDm(n).
[0071] During the blanking period BLK after the sub-period Pn of the operation period TD1, the differential signals DS1 to DSm respectively have blanking data (not shown). During the blanking period BLK, the electronic units EU11 to EUmn do not update the state during the operation period TD1.
[0072] After a blanking period BLK, after a delay time length tl1, differential signals DS1 to DSm each have a start signal ST. Subsequently, an operation period TD2 starts. In this embodiment, the start signal ST includes a start protocol SPT. The start protocol SPT has a waveform or digital code recognizable by electronic units EU11, EU21, …, EUm1. When the electronic units EU11, EU21, …, EUm1 receive a high-level signal SH and the start protocol SPT, the electronic units EU11, EU21, …, EUm1 generate scan signals SS11, SS21, …, SSm1 during a sub-period P1 of the operation period TD2. The microcontroller UIC11 operates according to the scan signal SS11 during the sub-period P1 of the operation period TD2, and outputs drive signals S1 to S3 to electronic components E11_1 to E11_3 respectively according to data DD1(1), thereby driving the electronic components E11_1 to E11_3. In addition, the microcontroller UIC11 generates a scan signal SS12 according to the scan signal SS11 during the sub-period P2 of the operation period TD2.
[0073] For example, the microcontroller UIC11 may include a shift register. The microcontroller UIC11 receives the high-level signal SH. When the differential signal DS1 received by the microcontroller UIC11 includes the start protocol SPT, the microcontroller UIC11 outputs drive signals S1 to S3 to the plurality of electronic components respectively, and outputs a scan signal to the shift register of the microcontroller in the next row (i.e., the second row).
[0074] The microcontroller UIC21 operates according to the scan signal SS21 during the sub-period P1 of the operation period TD2, thereby driving electronic components E21_1 to E21_3 according to data DD2(1). In addition, the microcontroller UIC21 generates a scan signal SS22 according to the scan signal SS21 during the sub-period P2 of the operation period TD2.
[0075] The microcontroller UICm1 operates according to the scan signal SSm1 during the sub-period P1 of the operation period TD2, thereby driving a plurality of electronic components in the electronic unit EUm1 according to data DDm(1). In addition, the microcontroller UIC21 generates a scan signal SSm2 according to the scan signal SSm1 during the sub-period P2 of the operation period TD2.
[0076] Please refer to Figure 6 , Figure 6is a schematic diagram of a microcontroller shown according to an embodiment of the present disclosure. In this embodiment, the microcontroller UIC is used to drive electronic components E1 to E6. The microcontroller UIC includes a decoder 310, a scan signal generator 320, a latch 330, a converter 340, and a shift register 350. The microcontroller UIC can be a general-purpose microcontroller. The microcontroller UIC can be applicable, for example, to a microcontroller such as Figure 3 the microcontroller UIC11 or the electronic unit EU12 shown.
[0077] First, taking the microcontroller UIC as the Figure 3 microcontroller UIC11 shown as an example, the decoder 310 receives the differential signal DS1 and generates a start signal ST. In addition, the decoder 310 generates a signal DD according to the differential signal DS1. In this example, the signal DD can be Figure 3 the data DD1(1) shown. For example, the decoder 310 can decode the differential signal DS1 to generate a start signal ST and a signal DD.
[0078] In some embodiments, the differential signal DS1 is a clock-embedded differential signal, and the decoder 310 can decode the differential signal DS1 to generate a start signal ST, a signal DD, and a clock (not shown).
[0079] In this example, the scan signal generator 320 is electrically connected to the decoder 310, the latch 330, the converter 340, and the shift register 350. The scan signal generator 320 receives the start signal ST and outputs a scan signal SS1 to the latch 330. In this example, the scan signal SS1 can be Figure 3 the scan signal SS11 shown. Specifically, the scan signal generator 320 generates a scan signal SS1 according to the start signal ST and outputs the scan signal SS1 to the latch 330. The latch 330 latches the signal DD from the decoder 310 in response to the scan signal SS1. The converter 340 outputs drive signals S1 to S6 to the electronic components E1 to E6 according to the signal DD from the latch 330 in response to the scan signal SS1.
[0080] In addition, the scan signal SS1 is output to the shift register 350. The shift register 350 outputs a scan signal SS2 to the shift register of the next line. In this example, the scan signal SS2 can be Figure 3 the scan signal SS12 shown.
[0081] Taking the microcontroller UIC as the Figure 3Taking the microcontroller of the electronic unit EU12 shown as an example, the decoder 310 receives the differential signal DS1 in response to the scan signal SS1 from the shift register of the previous row. In addition, the decoder 310 generates the signal DD according to the differential signal DS1. The signal DD can be the data DD1(2). For example, the decoder 310 can decode the differential signal DS1 to generate the signal DD.
[0082] In this example, the scan signal generator 320 does not operate. The latch 330 latches the signal DD from the decoder 310 in response to the scan signal SS1 from the shift register of the previous row. The converter 340 outputs the drive signals S1 to S6 to the electronic components E1 to E6 according to the signal DD from the latch 330 in response to the scan signal SS1.
[0083] In addition, the scan signal SS1 is output to the shift register 350. The shift register 350 outputs the scan signal SS2 to the shift register of the next row.
[0084] In one embodiment, the signal DD is a digital signal. The drive signals S1 to S6 can be current signals respectively. Therefore, the converter 340 is a conversion circuit that converts a digital signal into a current signal. In one embodiment, the signal DD is a digital signal. The drive signals S1 to S6 can be PWM signals respectively. Therefore, the converter 340 is a conversion circuit that converts a digital signal into a PWM signal. In one embodiment, the signal DD is a digital signal. The drive signals S1 to S6 can be voltage signals respectively. Therefore, the converter 340 is a conversion circuit that converts a digital signal into a voltage signal.
[0085] In this embodiment, the electronic components E1 to E6 may come from the electronic unit. In other words, the microcontroller UIC can drive multiple electronic components of at least one electronic unit.
[0086] In summary, the electronic device includes a plurality of electronic units and a data driver. The data driver provides a differential signal. The microcontroller of the electronic unit generates a plurality of drive signals according to the differential signal and inputs the plurality of drive signals to the plurality of electronic components respectively. The differential signal can reduce signal interference. The microcontroller can generate drive signals according to the differential signal. In this way, the electronic device can reduce signal interference and electromagnetic interference and operate correctly. In addition, the microcontroller can decode the differential signal. The differential signal is a clock-embedded differential signal or a scrambled differential signal.
