Thereby, one of the display material DH and the black material BC1 will be transmitted to the latch ιι3. When the display data D11 is transferred to _!|(1), (7) the locker 113 will flash the lock: the data D11, and according to the latch signal SRU, it is determined whether to output the display shell, D11. Further, when the black data Βα is transmitted to the latch ι 3, the latch 113 latches the black data BC1 and determines whether or not the black data B1 i composed of the black data BC1 is rotated in accordance with the latch signal SRn. On the other hand, the third end of the switch 112 leads to the first end or the second end of the switch 112 according to the black insertion control signal IB1. Thereby, the display material D12, one of the black data BC1 will be transmitted to the latch u4. Therefore, when the display data D12 is transmitted to the latch 114, the latch 114 will latch the display data D12 and decide whether to lose 201233063 HM-2010-0053-TW according to the latch signal SR12: S5385twf.doc/n The data D12 is displayed. Further, when the black data BC1 is transferred to the latch 114, the latch 114 latches the black data BC1 and decides whether or not to output the black data B12 composed of the black data BC1 in accordance with the latch signal SR12. Referring to Figure 1, the drive unit 12A includes multiplexers 121 and 130, latch states 122-123, level shifters 124-125, digital-to-analog converters 126-127, and buffers 128-129. The multiplexer 121 has first to fourth connection terminals, and the first 舆 second connection end of the multiplexer 121 receives the display materials D11 and D12, or receives the black insertion data B11 and B12. In addition, the multiplexer 121 conducts its first and second connection ends to its third and fourth connection ends, respectively, or conducts its first and second connection ends to its fourth and third connection ends, respectively. . The latch 122 is electrically connected to the third connection end of the multiplexer 121, and determines whether to output the data from the second connection end of the multiplexer κι according to the latch number SR13. Furthermore, the latch 123 is electrically connected to the fourth connection end of the multiplexer 121, and determines whether to output the data from the fourth connection end of the multiplexer 121 according to the latch signal SR14. The level private bit 124 is electrically connected to the interrogator 122 and adjusts the level of the data output by the flash lock = 2 to push the digit of the back end to the internal switch of the analog converter 126. Furthermore, the digital to analog converter 126 is electrically coupled to the level shifter 124 and converts the data output by the level shifter 124 into an analog signal to produce a display signal SD11 or a black signal SB11. For example, when the current unit 11 outputs the display data Du~: the digit to analog converter 126 will generate the display signal SD11. Conversely, when the front unit]10 outputs the black data B11~B12, the digit to analogy 201233063 HM-2010-005 3-TW 35385twf.doc/n 126 will generate the black signal SB11. Similarly, the level shifter 125 is electrically coupled to the latch 123 and adjusts the level of the data output by the latch 123 to push the digits of the back end to the internal switch of the analog switching state 127. The digital to analog converter 127 is electrically coupled to the level shifter 125, and converts the data output by the level shifter 125 into an analog signal to generate a display signal SD12 or a black signal SB12. For example, when the current unit 11 outputs the display data D11 to D12, the digit-to-analog converter 127 generates the display signal SD12. On the other hand, when the arranging unit 110 outputs the black data B1 1 to B 12, the digit-to-analog converter 127 generates the black signal SB12. The correspondence between the display signals SD11 to SD12 and the display data D11-D12, and the correspondence between the black insertion signals SB11 to SB12 and the black insertion data B11 to B12 depend on the switching of the multiplexer 121. For example, when the current unit 110 outputs the display data D11 D D12, and the first and second connection ends of the multiplexer 121 are respectively connected to the third and fourth connection ends thereof, the display signal SD11 is displayed as the display material DU. The driving unit 12 converts the signal obtained after the conversion, and the display signal SD12 is a signal obtained after the display data D12 is converted by the driving unit 120. In contrast, when the current unit 11() outputs the display data dii to D12, and the first and second connection ends of the multiplexer 121 are respectively connected to the fourth and third connection ends thereof, the display signal SD11 is the display data D12. The signal obtained after the conversion by the driving unit 120 is displayed, and the δ hole number SD12 is displayed as a signal obtained after the display data dii is converted by the driving unit 12〇. By analogy, the correspondence between the black signal SB11~SB12 and the black data Β11~Β12 is inserted. 201233063 HM-2010-0053-TW 35385twf.doc/n Furthermore, the 'buffer 128 is electrically connected to the analog converter ι26, and the signal SD11 is amplified or the black signal SB11 is inserted. In addition, the buffer 129 is electrically connected to the analog converter 129 and amplifies the display signal SD12 or the black signal SB12. It is worth mentioning that in the present embodiment, the digital to analog converters 126 and 127 are used to generate display signals SD11 and SD12 having different polarities. Therefore, in order to achieve polarity switching, the display signals SD11 and SD12 must be switched via the multiplexer 130 before the pixels to the back end are provided. Here, the multiplexer 130 has first to fourth connection terminals, and the first and second connection ends of the multiplexer 130 are electrically connected to the buffers 128 and 129, respectively, to receive the amplified display signal SD11~ The SD12 receives the amplified black signals SB11 to SB12. The multiplexer 130 further conducts the first and second connecting ends thereof to the third and fourth connecting ends thereof, or connects the first and second connecting ends thereof to the fourth and third connecting ends thereof, respectively. Thereby switching the polarity of the signal. 2 is a block diagram of a source driver in accordance with another embodiment of the present invention.
