[0064] The present invention provides an electronic device, including a timing control unit for providing a synchronization signal to a touch signal processing unit and a light source driving unit. In this way, the touch signal processing unit and the light source driving unit can use the synchronization signal as a reference point to adjust their respective timings to prevent signals from interfering with each other.

[0065] Figure 1 1 is a block diagram for illustrating the operating principle of an electronic device 1 according to some embodiments of the present invention. The electronic device 1 may include a display panel 10, a light emitting component layer 220, a touch component layer 210, a timing control unit 300, a light source driving unit 310, and a touch processing unit 400. The light emitting component layer 220 is used to provide a light source to the display panel 10. The touch component layer overlaps with the display panel 10. The timing control unit 300 is electrically connected to the display panel 10 for providing a synchronization signal Vsyn. The light source driving unit 310 is electrically connected to the light emitting component layer 220 and is used to receive the synchronization signal Vsyn. The touch processing unit 400 is electrically connected to the touch component layer 220 for receiving the synchronization signal Vsyn. According to some embodiments, the electronic device 1 may include a light source module 20, a display circuit board 30, and a touch circuit board 40, but is not limited thereto. The display circuit board 30 may include a timing control unit 300 and a light source driving unit 310, and the touch circuit board 40 may include a touch processing unit 400.

[0066] The position of the touch component layer 210 is not limited. For example, the touch component layer 210 may be an in-cell type, for example, the touch component layer 210 may be embedded in the light source module. Figure 3A As shown, the light source module 20A may include a light emitting component layer 220 and a touch component layer 210. Alternatively, the touch component layer 210 may be an out-cell type, for example, the touch component layer 210 may be in a module separate from the light source module. Figure 3B As shown, the touch component layer 210 may also be disposed in the touch panel 50 , and the touch panel 50 and the light source module 20B are separate modules.

[0067] Refer to Figure 1 The display circuit board 30 may include a timing control unit 300 and a light source driving unit 310. The timing control unit 300 may be electrically connected to the display panel 10 and may provide one or more synchronization signals Vsync to the display panel 10. For convenience of description, Figure 1Only one synchronization signal Vsync is displayed. In this way, the display panel 10 can continuously display multiple images according to multiple synchronization signals. The light source driving unit 310 can be electrically connected to the light emitting component layer 220, and can be used to receive one or more synchronization signals Vsync. The touch circuit board 40 can include a touch processing unit 400. The touch processing unit 400 can be electrically connected to the touch component layer 210, and can be used to receive one or more synchronization signals Vsync. It should be understood that Figure 1 It is only used to illustrate the operating principle of the electronic device 1 and is not used to limit the position, number, and size of each component.

[0068] Figure 2 1 is a timing diagram showing the temporal relationship between a synchronization signal, a touch signal, and a backlight scanning signal according to some embodiments of the present invention. Figure 2 The method of the electronic device 1 of the present invention is described. The display panel 10 can continuously display multiple frames, such as frames F1, F2, ..., Fq, etc., according to multiple synchronization signals (synchronization signals Vsyn_1, Vsyn_2, ... Vsyn_q, Vsyn_q+1, ..., etc.). That is, one synchronization signal Vsyn activates one frame, for example, the synchronization signal Vsyn_1 activates the screen F1, the synchronization signal Vsyn_2 activates the screen F2, ... The earliest period of the frame F1 is the period Dv1 of the synchronization signal Vsyn_1, the earliest period of the frame F2 is the period Dv2 of the synchronization signal Vsyn_2, ....

[0069] The timing control unit 300 may provide a first synchronization signal Vsyn_a and a second synchronization signal Vsyn_b. Figure 2 As shown, the display panel 10 displays the first picture Fa according to the first synchronization signal Vsyn_a, and displays the second picture Fb according to the second synchronization signal Vsyn_b. The period T1 of the first picture Fa may include the period Dv1 of the first synchronization signal Vsyn_a, the first period D1, and the second period D2. In the first period D1, the touch processing unit 400 may receive the touch signal St from the touch component layer 210. Figure 2 The low position of the waveform represents the touch signal St. In the second period D2, the light source driving unit 310 can make the light emitting component layer 220 scan. Figure 2 In FIG. 2 , S1, S2, ..., S8 represent the scanning of the light emitting component layer 220. For example, please also refer to Figure 4 In the second period D2, eight scanning signal lines SC1 . . . SCM (M=8) are scanned. Figure 2 The S1 in can be expressed as Figure 4 The scanning signal line SC1 in the scanning is scanned, Figure 2 S2 in can be expressed as Figure 4The scanning signal line SC2 in the scanning is scanned, ... Figure 2 The S8 in the Figure 4 The scanning signal lines SCM (M=8) are scanned.

[0070] like Figure 2 As shown, the first period D1 and the second period D2 are separated. That is, the first period D1 and the second period D2 may be substantially adjacent to each other or have a time interval between them. For example, Figure 2 As shown, the first period D1 and the second period D2 in the first frame Fa may be adjacent to each other, that is, the last time point in the first period D1 and the earliest time point in the second period D2 may be the same time point. According to other embodiments, there is a time interval (not shown) between the first period D1 and the second period D2, that is, the last time point in the first period D1 and the earliest time point in the second period D2 are different time points, and there is a time interval between them, and during this time interval, the touch processing unit 400 does not receive a touch signal from the touch component layer 210, and the light-emitting component layer 220 does not perform scanning.

[0071] like Figure 2 As shown, the first period D1 may be located before the second period D2, but is not limited thereto. Figure 2 As shown, the second period D2 of the first picture Fa and the receiving time of the second synchronization signal Vsyn_b in the second picture Fb can be substantially connected, but is not limited to this. That is, the last time point of the second period D2 of the first picture Fa and the earliest time point of the second synchronization signal Vsyn_b in the second picture Fb are the same time point. In some embodiments, there is an interval between the second period D2 of the first picture Fa and the receiving time of the second synchronization signal Vsyn_b in the second picture Fb. In some embodiments, the time length of the first period D1 can be between 1msec and 12msec, for example, between 2 and 10msec, for example, between 4 and 10msec. The time length of the second period D2 can be between 1msec and 12msec, for example, between 2 and 10msec, for example, between 4 and 10msec.

[0072] like Figure 1 and Figure 2As shown, the light source driving unit 310 and the touch processing unit 400 are used to receive the first synchronization signal Vsyn_a and the second synchronization signal Vsyn_b. The display panel 10 can be used to display the first picture Fa and the second picture Fb, and the second picture Fb is adjacent to the first picture Fa. The period of the second picture Fb may include the period Dv2 of the second synchronization signal Vsyn_b, the third period D3, and the fourth period D4. During the third period D3, the touch processing unit 400 may not receive the touch signal from the touch component layer 210. During the fourth period D4, the light source driving unit 310 causes the light emitting component layer 220 to scan, and the third period D3 and the fourth period D4 are separated. The third period D3 may be located before the fourth period D4, but is not limited thereto.

[0073] like Figure 2 As shown, after the display panel 10 generates a single or multiple second frames Fb including the third period D3, the first frame Fa including the first period D1 can be generated again. Depending on the design requirements of the electronic device 1, the display panel 10 can be used to continuously display multiple frames, and the multiple frames can include two first frames Fa displayed in sequence and N second frames Fb between the two first frames Fa. For example, Figure 2 As shown, the display panel 10 can be used to continuously display a plurality of pictures, and the plurality of pictures can include a first picture F1(Fa), a first picture Fq(Fa), and N second pictures Fb between the first picture F1(Fa) and the first picture Fq(Fa). For example, N is a positive integer and can be between 1 and 15, but is not limited thereto.

[0074] By providing the synchronization signal Vsync, the start time and time length of the first period D1, the second period D2, the third period D3, and the fourth period D4 can be determined. In some embodiments, the time length ratio of the first period D1 and the second period D2 can be between 0.7 and 15, such as between 1 and 12, such as between 1.5 and 10, such as between 2 and 5, and the time length ratio of the third period D3 and the fourth period D4 can be between 0.7 and 15, such as between 1 and 12, such as between 1.5 and 10, such as between 2 and 5. According to some embodiments, the first period D1 can be greater than, equal to, or less than the second period D2, and the third period D3 can be greater than, equal to, or less than the fourth period D4. In some embodiments, the time length of the third period D3 can be between 1msec and 12msec, such as between 2 and 10msec, such as between 4 and 10msec. The time length of the fourth period D4 can be between 1msec and 12msec, such as between 2 and 10msec, such as between 4 and 10msec.

[0075] Reference Figure 2It should be understood that the duration of the period T1 of the first frame Fa displayed by the display panel 10 may be greater than or equal to the sum of the durations of the first period D1 and the second period D2, and the duration of the period T2 of the second frame Fb may also be greater than or equal to the sum of the durations of the third period D3 and the fourth period D4. For example, in some embodiments, there is a time interval between the first period D1 and the second period D2.

[0076] The timing control unit 300 may provide synchronization signals Vsyn_a and Vsyn_b at a fixed period so that each frame displayed by the display panel 10 has the same time length. In some embodiments, the time length of the period T1 of the first frame Fa and the time length of the period T2 of the second frame Fb may be equal, but not limited to this. According to some embodiments, T1 may be less than T2, or T1 may be greater than T2. ​​Each frame may also have a different length from each other. In some embodiments, the first period D1 included in each first frame Fa displayed by the display panel 10 has the same time length, and the second period D2 included in each first frame Fa has the same time length.

[0077] like Figure 2 As shown, according to some embodiments, since the first period D1 and the second period D2 are separated, the electronic device 1 of the present invention can prevent the signals of the driving circuits of the touch component layer 210 and the light emitting component layer 220 from interfering with each other, thereby avoiding the generation of display defects such as ghost points and / or avoiding the generation of noise. Figure 1 The configurations of the display panel 10 , the display circuit board 30 , and the touch circuit board 40 are further described.

[0078] like Figure 1 As shown, the display circuit board 30 may further include an electrical connection unit 340 . The display circuit board 30 may be electrically connected to the light emitting component layer 220 in the light source module 20 via the electrical connection unit 340 .

[0079] like Figure 1 As shown, the touch circuit board 40 may further include a microcontroller unit 410 and a sensor connection unit 420. The microcontroller unit 410 can be used to calculate the touch signal St from the touch component 210 to obtain the touch coordinate point. The touch circuit board 40 can be electrically connected to the touch component 210 in the light source module 20 via the sensor connection unit 420.

[0080] The display panel 10 may be any suitable type of display panel, such as a liquid crystal display panel, an organic light emitting diode display panel, or an inorganic light emitting diode display panel, but is not limited thereto. Figure 1As shown, the display panel 10 includes a display area 100, a source driver unit 110, and a gate driver unit 120. A plurality of display units (not shown) may be arranged in a matrix and disposed in the display area 100, that is, the plurality of display units may be a plurality of display units arranged along a first direction (X direction) and along a second direction (Y direction). The first direction and the second direction are different, for example, may be vertical.

[0081] exist Figure 1 Although not shown in the figure, a plurality of gate lines may be extended along the first direction (X direction) and electrically connected to the gate driving unit 120. Each gate line may be electrically connected to a row of display units. According to some embodiments, the number of the gate driving unit 120 may be one, two, or more, without limitation. Figure 1 The number of gate driving units 120 is two. A portion of the plurality of gate lines may be electrically connected to the gate driving unit 120 on the left, and another portion of the plurality of gate lines may be electrically connected to the gate driving unit 120 on the right. Although not shown in the figure, a plurality of data lines may be extended along the second direction (Y direction) and electrically connected to the source driving unit 110. Each data line may be electrically connected to a column of display units.

[0082] As described above, each display unit can be electrically connected to the gate driving unit 120 via a gate line, and electrically connected to the source driving unit 110 via a data line. The display unit can be used to display three primary color signals such as R, G, and B, but is not limited thereto. The display unit may include a pixel electrode and a corresponding driving unit (such as a TFT; a transistor), which will not be described in detail here. The source driving unit 110 can be used to input signals to the display units in the display area 100, and the gate driving unit 120 can be used to perform switching actions of the display units (or pixel units) of each row (row) of the display area 100. When the display panel 10 performs a scanning action of the display area 100, the gate driving unit 120 can sequentially open a whole column of pixels, and let the source driving unit 110 be responsible for the input action of the signal of the display area 100 to provide the signals required by the pixels in the display area 100. For example, the gate driving unit 120 can be used to scan the display panel 10 during the period T1 of the first frame Fa. In this way, the gate driving unit 120 can sequentially turn on (scan) the display units in the first row, the second row, ..., to the last row.

[0083] That is, if Figure 2As shown, the gate line G1 scans the display units in the first column, the gate line G2 scans the display units in the second column... and the gate line Gp scans the display units in the p-th column. In this way, the gate driving unit 120 completes the scanning time of the display units in the first column, the second column... to the last column (the p-th column), which is the time of one screen. During the period T1 of the first screen Fa, the gate driving unit 120 scans the multiple display units in the display panel 10 via the gate lines G1, G2, ..., Gp. Similarly, during the period T2 of the second screen Fb, the gate driving unit 120 scans the multiple display units in the display panel 10 via the gate lines G1, G2, ..., Gp. In some embodiments, the gate line G1 may start scanning after the synchronization signal Vsyn_a or Vsyn_b, but is not limited thereto. In some embodiments, as Figure 2 As shown, the synchronization signal Vsyn_a or Vsyn_b is received immediately when the scanning of the gate line Gp ends, but it is not limited thereto. In some embodiments, as Figure 2 As shown, the scanning time of each gate line G1, G2, ..., Gp is ​​connected to each other, but not limited thereto. In some embodiments, the scanning time of the gate line G1 may overlap with the synchronization signal Vsyn_a or Vsyn_b.

[0084] like Figure 2 As shown, according to some embodiments, in the first frame F1 (Fa), the gate driving unit 120 sequentially scans the multiple display units in the display panel row by row, and in the second frame F2 (Fb) adjacent to the first frame F1 (Fa), the gate driving unit 120 also performs scanning in the same manner. That is, the scanning performed by the gate driving unit 120 is not interrupted by the touch signal, nor is it interrupted by the backlight scanning signal. According to some embodiments, the receiving period D1 of the touch signal may at least partially overlap with the scanning time of one of the gate lines (or multiple gate lines). According to some embodiments, the scanning period D2 of the light-emitting component layer 220 may at least partially overlap with the scanning time of another gate line (or multiple gate lines).

[0085] Figure 3A FIG. 1 is a partial cross-sectional view of an electronic device 1 according to some embodiments of the present invention. Figure 3AAs shown, the electronic device 1 includes a display panel 10, a light emitting module 20A, and a cover substrate 108. The display panel 10 is disposed on the light emitting module 20A. The display panel 10 includes a first substrate 10S1, a second substrate 10S2, and a display layer 104, and the display layer 104 is disposed between the first substrate 10S1 and the second substrate 10S2. The cover plate 108 is adhered to the display panel 10 via an adhesive material 106. The light emitting component layer 220 and the touch component layer 210 can overlap in the Z direction. The first substrate 10S1 and the second substrate 10S2 can be a rigid substrate or a flexible substrate, respectively. The first substrate 10S1 and the second substrate 10S2 can be glass, plastic, quartz, or a combination thereof, respectively.

[0086] The present invention does not limit the type of the display layer 104. In some embodiments, the display layer 104 may include a liquid crystal layer, a pixel layer, an electrode layer, a circuit layer, etc., but is not limited thereto. In other embodiments, the display layer 104 may include an organic light emitting layer.

[0087] The adhesive material 106 may be used to adhere the display panel 10 and the cover substrate 108. The adhesive material 106 may include a light-transmitting material, such as silicone resin, epoxy resin, acrylic resin, other suitable materials, or a combination thereof, but is not limited thereto.

[0088] By disposing a cover substrate 108 above the display panel 10, moisture can be further prevented from entering the space inside the display panel 10. According to some embodiments, when the hardness of the cover substrate 108 is large enough, it can prevent the display panel 10 from being damaged when an external object collides with the electronic device 10, but the present invention is not limited thereto. The material of the cover substrate 108 may include, for example, glass, polyimide (PI), polyethylene terephthalate (PET), other suitable materials or a combination of the above materials, but the present invention is not limited thereto.

[0089] In some embodiments, Figure 3A As shown, the light-emitting module 20A includes a substrate 20S, a touch component layer 210, a light-emitting component layer 220, and an optical film 202. The light-emitting component layer 220 and the touch component layer 210 are arranged on the same substrate (substrate 20S). The touch component layer 210 may include touch electrodes and touch circuits. For the convenience of explanation, the touch electrodes and touch circuits are not shown. The touch electrodes may be electrically connected to the touch processing unit 400 via the touch circuits. For example, the touch component layer 210 may include a single-layer touch circuit, or a double-layer touch circuit, but the number of touch circuits is not limited thereto. In some embodiments, the touch component layer 210 may include an electromagnetic coil. As Figure 3AAs shown, the electronic device may further include an electromagnetic induction component 21, which can be used to sense the electromagnetic coil in the touch component layer 210. Specifically, the electromagnetic induction component 21 can be a component such as a stylus, but is not limited thereto. The electromagnetic coil in the touch component layer 210 can be a coil loop for scanning to identify the touch coordinates of the electromagnetic induction component 21.

[0090] Specifically, within the magnetic field range generated by the energized touch component layer 210, the resonant circuit from the electromagnetic induction component 21 can accumulate weak electrical energy. When the pen accumulates energy, the control circuit of the touch component layer 210 will stop providing current to the circulating coil and connect the circulating coil to the receiving circuit. At this time, the energy accumulated by the electromagnetic induction component 21 will be transmitted back to the touch circuit of the touch component layer 210 through the free oscillation of the resonant circuit. After transmitting the energy back to the touch circuit layer 210, the control circuit first scans the circulating coil of the touch circuit layer 210 to preliminarily detect the approximate position of the pen. Next, the multiple circulating coils around the electromagnetic induction component 21 are scanned, and the detected signals are calculated on the touch circuit board 40. In this way, the coordinate value of the electromagnetic induction component 21 can be calculated very accurately.

[0091] In some embodiments, the touch component layer 210 may include a plurality of touch electrodes, and the plurality of touch electrodes may include transmitting electrodes, sensing electrodes, capacitive electrodes, resistive electrodes, or a combination thereof.

Figure 3AAs shown, the light source module 20A further includes an optical film 102 disposed between the light emitting component layer 220 and the display panel 10. The material of the optical film 102 may include polyethylene terephthalate (PET), polymethylmethacrylate (PMMA), polyethylene naphthalate (PEN), polyvinylidene difluoride (PVDF), cellulose triacetate (TAC), wavelength conversion material, fluorescence, phosphorescence, other suitable materials, or a combination thereof, but not limited thereto. The optical film 102 may include a diffusion film, a brightness enhancement film (BEF), a wavelength conversion film, a quantum dot film (QD Film), a blue light gain film, a prism sheet, or a combination thereof. The optical film 102 may be a single layer or a multilayer.

Figure 3B As shown, the electronic device 1 may further include a touch panel 50 disposed on the display panel 10, and the touch panel 50 includes a touch component layer 210. In some embodiments, the touch panel 50 further includes a substrate 50S. The substrate 50S may include the same or similar materials as the substrate 10S1 and the substrate 20S1. The touch panel 50 may be adhered between the cover substrate 108 and the display panel 10 through the adhesive material 106.

[0094] Figure 4 is a schematic diagram showing the driving of each light-emitting unit L by the light-emitting component layer 220 according to some embodiments of the present invention. Figure 4 The light emitting component layer 220 may be Figure 3A and Figure 3B The light emitting component layer shown in FIG. Figure 4, the light emitting component layer 220 may include a plurality of light emitting units L (e.g., L11 to LMN), a plurality of scanning signal lines SC, and a plurality of channel signal lines CH, which are disposed on the substrate 20S. For example, the plurality of scanning signal lines SC may include M scanning signal lines SC1, SC2, SC3, ..., SCM extending in a first direction (X direction), which are electrically connected to the corresponding light emitting units L. On the other hand, the plurality of channel signal lines CH may include N channel signal lines CH1, CH2, CH3, CH4, CH5, ..., CHN extending in a second direction (Y direction), which are electrically connected to the corresponding light emitting components L. The first direction and the second direction are different, for example, the first direction is perpendicular to the second direction. It should be understood that the present invention does not limit the number and spatial configuration of the scanning signal lines SC and the channel signal lines CH.

[0095] like Figure 4 As shown, the plurality of light-emitting units L may be arranged in a matrix, for example, may include M×N light-emitting units, and are disposed on the substrate 20S. M and N are positive integers, and M may be greater than, less than, or equal to N. M and N may be individually between 1 and 150, for example, between 1 and 128, for example, between 2 and 128, for example, between 2 and 100, for example, between 2 and 50, for example, between 4 and 25, for example, between 4 and 20, for example, between 5 and 15. When M=1, N is greater than 1 and within the above range. When N=1, M is greater than 1 and within the above range. Specifically, the plurality of light-emitting units L include light-emitting units of M columns (row) and N rows (column), the columns (row) extending along the first direction (X direction), and the rows (column) extending along the second direction (Y direction). The light-emitting unit may be labeled as Lab, which is represented by the light-emitting unit of the ath column and the bth row. For example, the light emitting unit in the first column and the first row is labeled as L11, the light emitting unit in the second column and the first row is labeled as L21, and the light emitting unit in the second column and the third row is labeled as L23.

[0096] The plurality of light emitting units L may be direct-type backlights, providing light sources for the display panel 10. The plurality of light emitting units L may be scanning-type backlights, that is, the M×N light emitting units may be turned on in sequence according to a scanning signal. Figure 4As shown, taking the light-emitting unit L11 as an example, the first end TR1 of the light-emitting unit L11 can be electrically connected to the scan signal line SC1, and the second end TR2 of the light-emitting unit L11 can be electrically connected to the channel signal line CH1. According to some embodiments, the first end TR1 can be a positive electrode, and the second end TR2 can be a negative electrode. According to some embodiments, the first end TR1 can be a negative electrode, and the second end TR2 can be a positive electrode. The light-emitting units in the same column can be electrically connected to the same scan signal line, for example, the light-emitting units L11, L12...L1N in the same column are electrically connected to the same scan signal line SC1. The light-emitting units in the same row can be electrically connected to the same channel signal line, for example, the light-emitting units L11, L21...LM1 in the same row are electrically connected to the same channel signal line CH1.

[0097] The light source driving unit 310 can determine the magnitude of the conduction current of each signal line in the channel signal line CH to determine the brightness of the light source L. After the corresponding light sources L are turned on in sequence from the scanning signal line SC1 to the scanning signal line SCM, they will return to the scanning signal line SC1 and repeat the above actions to complete the continuous scanning of the scanning signal line SC. The light-emitting unit and the scanning signal line SC can be electrically connected via a switch component (not shown), and the switch component can control the conduction of the scanning signal line SC. The scanning signal lines SC1, SC2...SCM are turned on in time sequence to complete the scanning of all M×N light-emitting units.

[0098] For example, Figure 2 As shown, taking M equal to 8 as an example, when there are 8 scanning signal lines SC, in the second period D2, the scanning signal lines SC1, SC2...SC8 are turned on in time sequence to complete the scanning of all M×N light-emitting units. Data can be input through the channel signal line CH, and the brightness and dimming information of each individual row of light-emitting units can be controlled according to the data. In this way, in the light-emitting component layer 220, the brightness and dimming information of individual light-emitting units can be controlled by scanning the scanning signal line SC and the data input by the signal line CH, so as to achieve the partition brightness change of the light source L of the light-emitting component layer 220.

[0099] In summary, the present invention provides an electronic device, including a timing control unit for providing a synchronization signal to a touch processing unit and a light source driving unit. In this way, the touch processing unit and the light source driving unit can use the synchronization signal as a reference point to adjust their respective timings, thereby avoiding or reducing the mutual interference between the signal of the touch component and the signal of the light emitting component driving circuit, thereby avoiding or reducing the generation of display defects such as ghost points.
