Fig. 2 is a flow chart illustrating steps of a driving method 20 according to some embodiments of the disclosure. In some embodiments, the driving method 20 may be performed by the tiled display apparatus 10 shown in fig. 1. For easy understanding of the driving method 20, please refer to fig. 1.
In step 21, two kinds of electrodes of different screens are scanned and used for transmitting signals.
In some embodiments, referring to fig. 1 and fig. 2, after the edge of the first display screen 100 and the edge portion of the second display screen 200 are tiled, the first electrodes of the first display screen 100 and the second electrodes of the second display screen 200 are respectively driven by the tiled display device 10 for scanning and pairing, so as to generate the first position data of the first tiled region a 1. The driving of the first display screen 100 and the second display screen 200, respectively, will be described in terms of timing and electrode positions.
In some embodiments, the first display screen 100 and the second display screen 200 are driven simultaneously. The driving timings of the first display screen 100 and the second display screen 200 are as follows.
Watch 1
Referring to table one, in terms of timing, in the first stage G1, the plurality of first electrodes E1 to E26 of the first display screen 100 are driven to generate the first control signal, and then, in the first stage G1, the plurality of second electrodes E27 to E52 of the second display screen 100 are driven to receive the first control signal.
In the second phase G2, the plurality of second electrodes E27-E52 of the second display screen 100 are driven to generate the second control signal, and then in the second phase G2, the plurality of first electrodes E1-E26 of the first display screen 100 are driven to receive the second control signal. The operation of the third stage G3 is the same as the first stage G1. The operation of the fourth stage G4 is the same as that of the second stage G2.
With reference to fig. 1 and 2, the first electrode E8 of the first display screen is substantially aligned with the second electrode E52 of the second display screen along the X-axis of the horizontal direction with respect to the electrode position. However, if the first electrode E8 and the second electrode E52 have a Y-axis displacement in the vertical direction, the first electrode E8 and the second electrode E52 overlap along the X-axis in the horizontal direction, and the second electrode E52 can receive the first control signal generated by the first electrode E8, and the splicing is considered to be successful. The first electrode E8 is considered to be successfully spliced when it receives the second control signal generated by the second electrode E52.
For example, the first electrode E8 and the second electrode E52 have a displacement of one third along the Y axis in the vertical direction. The two-thirds of the first electrode E8 overlaps the X-axis of the two-thirds of the second electrode E52 along the horizontal direction, and the second electrode E52 receives the first control signal generated by the first electrode E8 and the first electrode E8 receives the second control signal generated by the second electrode E52, which are considered as successful splices.
In some embodiments, the first electrodes E1-E26 are not able to receive the second control signals of the second electrodes E27-E52 in terms of timing and electrodes, and are considered as a splice failure. If the second electrodes E27-E52 cannot receive the first control signals from the first electrodes E1-E26 in terms of timing and electrodes, the splicing is considered as a failed splicing.
It should be noted that once the edge portions of the two display screens are spliced, the pair matching and identification can be quickly achieved through the driving of the electrodes in the peripheral area in terms of timing and electrodes, so that the two display screens can display continuous pictures.
In step 22, after the different screens are spliced, the position information of the spliced area is obtained.
In some embodiments, referring to fig. 1 and 2, if at least one of the first electrodes E1 through E26 receives a second control signal of at least one of the second electrodes E27 through E52, the first display screen 100 obtains first position information of the first splicing area a1 according to the second control signal.
If at least one of the second electrodes E27-E52 receives the first control signal from the first electrodes E1-E26, the second display screen 200 obtains the first position information of the first splicing area A1 according to the first control signal. The position information of the first splicing area A1 is obtained by exchanging signals through the first display screen 100 and the second display screen 200 by wireless communication technology.
In some embodiments, if the position between the first display screen 100 and the second display screen 200 is not changed, and after the first display screen 100 and the second display screen 200 respectively obtain the position information of the first splicing area a1, the first display screen 100 continuously drives the first electrodes E1 to E26 to detect whether the first splicing area a1 is changed. The second display screen 200 continuously drives the second electrodes E27-E52 to generate the second control signal or receive the first control signal to detect whether the first splicing area a1 is changed. It should be noted that, when the position of the first splicing area a1 is changed or the splicing display device 10 adds a display screen, the first display screen 100 and the second display screen 200 are coupled by using a wireless communication technology. When the position of the first splicing area a1 is not changed, the first display screen 100 and the second display screen 200 do not need to be coupled by wireless communication technology.
In some embodiments, referring to table one and fig. 1, the first display screen 100 performs at least one of the first stage G1 and the second stage G2 to exchange at least one of the first control signal and the second control signal. The second display screen 200 performs at least one of the first stage G1 and the second stage G2 to exchange at least one of the first control signal and the second control signal.
In step 23, the plurality of screens display the screen together according to the position data of the splicing region and the control signal.
In some embodiments, referring to fig. 1 and fig. 2, the first display screen 100 and the second display screen 200 jointly display continuous frames according to the first position data and the control signal of the first splicing area a 1.
In some embodiments, if the position between the first display screen 100 and the second display screen 200 is not changed, the first display screen 100 and the second display screen 200 display the image through the first position data and the control signal of the first splicing area a1 when spliced, without using wireless communication technology for coupling.
