The disclosure relates to an electronic device, and more particularly to an electronic device and a modulating device with short frame time length.
The driving method of existing electronic devices (such as displays or antenna arrays) is sequential driving, that is, row-by-row and column-by-column driving. The frame time length of an electronic device (such as a display or an antenna array) is determined by the number of data lines and the number of scan lines. However, the frame time length is limited by the charging time of data lines and scan lines. That is to say, the greater the number of data lines and the number of scan lines, the greater the time length of the frame time. Therefore, the time for updating the data of the electronic device is longer. It may be seen that how to provide a driving method for an electronic device with short frame time length is one of the research focuses of those skilled in the art.
The disclosure is directed to an electronic device and a modulating device with short frame time length.
According to an embodiment of the disclosure, an electronic device includes a substrate, a plurality of first signal lines, a plurality of second signal lines, and two first integrated circuits. The plurality of first signal lines are disposed on the substrate. The plurality of first signal lines are divided into a first group of signal lines and a second group of signal lines. The plurality of second signal lines are disposed on the substrate. The plurality of second signal lines are disposed alternately with the plurality of first signal lines. The two first integrated circuits are bonded on the substrate. Each of the two first integrated circuits are electrically connected to the first group of signal lines and the second group of signal lines. The first group of signal lines and the second group of signal lines are disposed alternately in columns.
According to an embodiment of the disclosure, a modulating device includes a substrate, a modulating element, a plurality of first signal lines, a plurality of second signal lines, and two first integrated circuits. The plurality of first signal lines are disposed on the substrate. The plurality of first signal lines are divided into a first group of signal lines and a second group of signal lines. One of the plurality of first signal lines is electrically connected to the modulating element. The plurality of second signal lines are disposed on the substrate. The plurality of second signal lines are disposed alternately with the plurality of first signal lines. One of the plurality of second signal lines is electrically connected to the modulating element. The two first integrated circuits are bonded on the substrate. Each of the two first integrated circuits are electrically connected to the first group of signal lines and the second group of signal lines. The first group of signal lines and the second group of signal lines are disposed alternately in columns.
Based on the above, each of the two first integrated circuits are electrically connected to the first group of signal lines and the second group of signal lines. Moreover, the first group of signal lines and the second group of signal lines are disposed alternately in columns. That is to say, the signals received by two adjacent signal lines come from different first integrated circuits. Therefore, the first signal lines do not need to wait for the adjacent preceding signal line to be charged before being charged. In this way, the frame time length of the electronic device may be shortened.

It should be mentioned here that, the first ICs 110-1 and 110-2 are each electrically connected to the first group of signal lines GL1 and the second group of signal lines GL2. Moreover, the first group of signal lines GL1 and the second group of signal lines GL2 are disposed alternately in columns. That is to say, the signals received by two adjacent signal lines come from different first ICs. Therefore, the charging of the first signal lines does not need to wait for the charging of the previous adjacent signal line to be completed. For example, the signal received by the first group of signal lines GL1 is from the first IC 110-1. The signal received by the second group of signal lines GL2 is from the first IC 110-2. The second group of signal lines GL2 does not need to wait for the charging of the adjacent first group of signal lines GL1 to be completed to charge. In this way, the frame time length of the electronic device 100 may be shortened.
In the present embodiment, the electronic device 100 may be, for example, a modulating device. The electronic device 100 further includes a plurality of modulating elements EE. For example, the plurality of modulating elements EE are disposed in a plurality of rows and a plurality of columns.

The electronic device 100 further includes second ICs 120-1 and 120-2. The second ICs 120-1 and 120-2 are bonded on the substrate SB.

During the time interval T2, the second IC 120-1 provides a scan signal SG2 to the second signal line LR2. The time length b for which the second IC 120-2 provides the scan signal SG2 is shorter than a time length a for which the first IC 110-2 provides the data signal group SD2.
During a time interval T3, the first IC 110-1 provides the data signal group SD1 to the first group of signal lines GL1. During the time interval T3, the second IC 120-1 provides a scan signal SG3 to the second signal line LR2. The time length b for which the second IC 120-2 provides the scan signal SG3 is shorter than the time length a.
During a time interval T4, the first IC 110-2 provides the data signal group SD2 to the second group of signal lines GL2. During the time interval T4, the second IC 120-2 provides a scan signal SG4 to the second signal line LR4. The time length b for which the second IC 120-2 provides the scan signal SG4 is shorter than the time length a.
It should be noted that, based on the current driving method, the frame time length is determined by the product of the time length a and a number G of the second signal lines LR1 to LR6, that is, the frame time length is equal to “a×G”. However, in the present embodiment, the signal received by the first group of signal lines GL1 in the time interval T1 is from the first IC 110-1. The signal received by the first group of signal lines GL2 in the time interval T2 is from the first IC 110-2. The first group of signal lines GL2 does not need to wait for the charging of the adjacent first group of signal lines GL1 to be completed to charge. This allows the time intervals T1 and T2 to be partially overlapped. Therefore, frame time lengths F(N) and F(N+1) of the present embodiment are respectively determined by the product of the time length b and the number of the second signal lines LR1 to LR6. That is, the frame time lengths F(N) and F(N+1) are equal to “b×G”. In this way, the frame time lengths F(N) and F(N+1) of the electronic device 100 may be shortened.

In the present embodiment, the second signal lines LR1 to LR6 are divided into the third group of signal lines GL3 and the fourth group of signal lines GL4. The second signal lines LR1, LR3, and LR5 are grouped into the third group of signal lines GL3. The second signal lines LR2, LR4, and LR6 are grouped into the fourth group of signal lines GL4. In other words, the third group of signal lines GL3 and the fourth group of signal lines GL4 are disposed alternately in rows. The second IC 220-1 is electrically connected to the third group of signal lines GL3. The second IC 220-2 is electrically connected to the fourth group of signal lines GL4.
In the present embodiments, the first ICs 210-1 and 210-2 are disposed along the first side S1 of the substrate SB. The second ICs 220-1 and 220-2 are respectively disposed along at least one side of the substrate SB different from the first side S1.

During the time interval T2, the first IC 210-1 provides the data signal group SD1 to the first group of signal lines GL1. The first IC 210-2 provides the data signal group SD2 to the second group of signal lines GL2. During the time interval T2, the second IC 220-1 provides the scan signal SG3 to the second signal line LR3. The second IC 220-2 provides the scan signal SG4 to the second signal line LR4. The time length b for which the second ICs 220-1 and 220-2 provide the scan signals SG3 and SG4 is shorter than the time length a.
It should be noted that, in the present embodiment, in each time interval, the signal received by the first group of signal lines GL1 is from the first IC 210-1. The signal received by the second group of signal lines GL2 in the time interval T2 is from the first IC 210-2. The second group of signal lines GL2 does not need to wait for the charging of the adjacent first group of signal lines GL1 to be completed to charge. Moreover, the signal received by the third group of signal lines GL3 is from the second IC 210-1. The signal received by the fourth group of signal lines GL4 is from the second IC 210-2. That is to say, the signals received by the third group of signal lines GL3 and GL4 are from different second ICs. This enables the supply timings of the time interval data signal groups SD1 and SD2 to be overlapped or even be completely the same, the supply timings of the scan signals SG1 and SG2 to be overlapped or even be completely the same, and the supply timings of the scan signals SG3 and SG4 to be overlapped or even be completely the same. Therefore, frame time lengths F(N) and F(N+1) of the present embodiment are respectively determined by half of the product of the time length a and the number of the second signal lines LR1 to LR6. That is, the frame time lengths F(N) and F(N+1) are equal to “(b×G)/2”. The frame time lengths F(N) and F(N+1) of the electronic device 200 are substantially half of the frame time lengths of the conventional driving method.
