N-1 To the first data line DL1, DL3...DL N-1 And transmits multiple second data signals DS2~DS corresponding to the second image IG2 respectively. N To the second data line DL2, DL4...DL N DS1~DS N-1 All are odd-numbered labels, DL2, DL4...DL N All are even-numbered labels.

[0075] The gate driving module 130 is coupled to the display panel 110. The gate driving module 130 is used to transmit multiple scan signals SS1~SS2 respectively. M To scan lines SL1~SL M For clarity, Figure 1 Only the first data signal DS1 and the first data signal DS are marked in the text. N-1 To represent all the first data signals DS1~DS N-1 Scan signals SS1~SS M And so on. Specifically, each of the first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 is electrically connected to scan lines SL1~SL2. M One of these data lines. The transistor in the sub-pixel is scanned by the corresponding scan signals SS1~SS2. M Initiate a decision scan. During the determination phase, sub-pixels are scanned by the corresponding first data signals DS1~DS2 according to the user's desired display. N-1 and the second data signal DS2~DS N Driven, the display panel 110 is based on the first data signals DS1~DS N-1 The first image IG1, viewed from a first-person perspective, is displayed, based on the second data signals DS2~DS1. N The second image, IG2, is displayed from a second-person perspective.

[0076] Therefore, the dual-view display device 100 disclosed herein transmits data via the first data lines DL1, DL3...DL N-1 Receive the first data signals DS1~DS corresponding to the first image IG1 N-1 And the second data lines DL2, DL4...DL N Receive the second data signal DS2~DS corresponding to the second image IG2 N The wiring configuration enables signal interleaving and real-time merging of two different images without prior image preprocessing. Therefore, when a user is positioned on the left or right side in front of the dual-view display device 100, the dual-view display device 100 can instantly and independently meet the display requirements of the first viewing angle (e.g., left viewing angle) and the second viewing angle (e.g., right viewing angle).

[0077] Furthermore, the dual-view display device 100 of this disclosure may also include a timing control module 140. The timing control module 140 is electrically connected to an external controller (not shown), a source drive module 120, and a gate drive module 130. In some embodiments, the timing control module 140 may be, but is not limited to, a timing controller (TCON), and it includes a processing unit and a storage unit electrically connected thereto. The timing control module 140 can be used to receive and store merged image data 141 from the external controller to the storage unit. The processing unit of the timing control module 140 generates a source drive control signal 142 based on the merged image data 141. The timing control module 140 transmits the source drive control signal 142 to the source drive module 120, causing the source drive module 120 to sequentially generate and output first data signals DS1~DS2 according to the source drive control signal 142. N-1 and the second data signal DS2~DS N And transmit it to the corresponding first data line DL1, DL3...DL N-1 and the second data lines DL2, DL4...DL N .

[0078] It is worth mentioning that the merged image data 141 may include first image data 1411 for displaying the first image IG1 and second image data 1412 for displaying the second image IG2. The second image data 1412 is contiguous after the first image data 1411. In other embodiments, the timing control module 140 may also receive and store the first image data 1411 and the second image data 1412 separately from an external controller to a storage unit, and the processing unit may directly generate a source drive control signal 142 based on the first image data 1411 and the second image data 1412. Whether the merged image data 141 is obtained directly or the first image data 1411 and the second image data 1412 are obtained separately, the timing control module 140 does not need to perform interleaved image preprocessing. The dual-view display device 100 of this disclosure only needs to utilize the signal interleaving configuration within the display panel 110 to achieve the goal of providing users with different viewing angles to view different images on a single panel.

[0079] Furthermore, the processing unit of the timing control module 140 can also receive a control command from an external controller and generate a gate drive control signal 143 according to the control command. The gate drive control signal 143 can be, but is not limited to, a data latch enable (DLE), a start clock (Star Pulse Signal), or an output enable. The gate drive module 130 receives the gate drive control signal 143 from the timing control module 140 and transmits scan signals SS1~SS1 respectively according to the gate drive control signal 143. M To the corresponding scan lines SL1~SL M In order to sequentially enable scan lines SL1~SL M .

[0080] In some embodiments, the source driver module 120 may include a plurality of first source driver chips 121 and a plurality of second source driver chips 122. Each of the first source driver chips 121 includes a plurality of first pins, and these first pins are used to transmit first data signals DS1~DS2 respectively. N-1 A portion of it is connected to the corresponding first data line DL1, DL3...DL N-1 Part of it. Each of the second source driver chips 122 includes multiple second pins, and these second pins are used to transmit second data signals DS2~DS3 respectively. N A portion of it is connected to the corresponding second data lines DL2, DL4...DL N Part of it. The number of first source driver chips 121 may be, for example, eight, and the number of second source driver chips 122 may be, for example, eight, but this disclosure is not limited thereto.

[0081] In some embodiments, the dual-view display device 100 may further include a plurality of first fan-out conductors FL1~FL2. N-1 and multiple second fan-out conductors FL2~FL N FL1~FL N-1 All are odd-numbered labels, FL2~FL N All are even-numbered labels. For clarity, Figure 1 Only the first fan-out conductor FL1 and the first fan-out conductor FL are marked. N-1 To represent all the first fan-out conductors FL1~FL N-1 The second fan-out conductor FL2~FL N And so on.

[0082] First fan-out wires FL1~FL N-1 One end is electrically connected to the first data lines DL1, DL3...DL N-1 The first fan-out conductors FL1~FL N-1 The other end is electrically connected to the first pin of all the first source driver chips 121 in the source driver module 120, so that the source driver module 120 is connected via the first fan-out wires FL1~FL N-1 Transmit the first data signals DS1~DS respectively N-1 To the corresponding first data lines DL1, DL3...DL N-1 The second fan-out conductor FL2~FL N One end is electrically connected to the second data lines DL2, DL4...DL respectively. N The second fan-out conductor FL2~FL N The other end is electrically connected to the second pin of all the second source driver chips 122 in the source driver module 120, so that the source driver module 120 is connected via the second fan-out wires FL2~FL N Transmit the second data signals DS2~DS respectively N To the corresponding second data lines DL2, DL4...DL N Specifically, the second fan-out conductors FL2~FL N Each of them is located on the same layer, and in order to avoid the first fan-out wires FL1~FL N-1 With the second fan-out conductor FL2~FL N If they collide, then the first fan-out wires FL1~FL N-1 The second fan-out conductor FL2~FL can be avoided by routing the cable across different layers (e.g., by detouring upwards or downwards). N Therefore, the dual-view display device 100 of this disclosure is transmitted via the first fan-out wires FL1~FL1. N-1 and the second fan-out conductors FL2~FL NThe first source driver chip 121 and the second source driver chip 122 in the source driver module 120 can be connected to the interleaved first data lines DL1, DL3...DL N-1 and the second data lines DL2, DL4...DL N It can achieve signal interleaving and merge two different images in real time without the need for image preprocessing procedures on the two different images.

[0083] Please refer to Figures 1, 2, 3A, and 3B, among which... Figure 2 In accordance with Figure 1 A cross-sectional view of the dual-view display device 100. Figure 3A To watch VA1 from a first-person perspective Figure 1 A schematic diagram of a dual-view display device 100. Figure 3B To watch VA2 from a second-person perspective Figure 1 A schematic diagram of a dual-view display device 100. As shown in Figures 1 to 3B, the dual-view display device 100 may further include a backlight module 150 and a barrier plate 160. The backlight module 150 is located below the display panel 110 and provides light to the display panel 110. The barrier plate 160 is disposed on the display panel 110 and includes a plurality of openings 161 arranged at intervals. These openings 161 are used to allow light penetrating the display panel 110 to pass through. In the first embodiment, each pair of these openings 161 is spaced apart by a distance G1, and the distance G1 is in units of sub-pixel size.

[0084] Light rays penetrating one of the first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 can be emitted outward from one of these openings 161 at a specific angle, while the remaining light rays are blocked by the barrier plate 160. Therefore, when a user views the display panel 110 from a first viewing angle VA1 (e.g., a left viewing angle), only the light rays emitted towards the first viewing angle VA1 (i.e., those used to receive the first data signals DS1~DS2) are emitted outward. N-1 The first data lines DL1, DL3...DL N-1 The first image IG1 can be seen by the user, so the display panel 110 can display the first image IG1 to the user. Conversely, when the user views the display panel 110 from a second viewing angle VA2 (e.g., a right viewing angle), only the light rays emitted towards the second viewing angle VA2 (i.e., the light rays used to receive the second data signals DS2~DS1) are visible to the user. N The second data lines DL2, DL4...DL NThe second image IG2 can be displayed on the display panel 110 for the user. In this way, the dual-view display device 100 of this disclosure not only utilizes the signal interleaving function within the panel, but also utilizes the opening configuration of the barrier plate 160 to achieve the input of two different image data on a single panel, so that users at different viewing angles can view different display images.

[0085] Please refer to Figures 4, 5, 6A, and 6B, where... Figure 4 This is a schematic diagram of the dual-view display device 200 according to the second embodiment of this disclosure. Figure 5 In accordance with Figure 4 A cross-sectional view of the dual-view display device 200. Figure 6A To watch VA1 from a first-person perspective Figure 4 A schematic diagram of a dual-view display device 200. Figure 6B To watch VA2 from a second-person perspective Figure 4 A schematic diagram of a dual-view display device 200 is shown. As shown in Figures 4 to 6B, the dual-view display device 200 is used to provide a user with the ability to view a first image IG1 and a second image IG2 from a first viewing angle VA1 and a second viewing angle VA2, respectively, and includes a display panel 210, a source driving module 220, a gate driving module 230, a timing control module 240, a backlight module 250, and a barrier plate 260. The dual-view display device 200 is similar to the dual-view display device 100 of the first embodiment.

[0086] The difference lies in the fact that the multiple data lines of the display panel 210 are from... Figure 4 The numbers from left to right are dDL1, dDL2, dDL3, dDL4, dDL5, dDL6…dDL N It contains multiple first data lines dDL1, dDL2, dDL3...dDL N-3 and multiple second data lines dDL4, dDL5, dDL6…dDL N Where N can be an integer greater than 3. It is worth noting that the first data lines dDL1, dDL2, dDL3…dDL… N-3 Each of the three in the data is connected to the second data line dDL4, dDL5, dDL6...dDL N The three data lines are arranged in an alternating pattern. The first data line is dDL1, dDL2, dDL3…dDL N-3 Used to receive multiple first data signals (unlabeled) corresponding to the first image IG1 from the source drive module 220, while the second data lines dDL4, dDL5, dDL6...dDL N Used to receive multiple second data signals (unlabeled) corresponding to the second image IG2 from the source drive module 220.

[0087] Furthermore, each pair of the plurality of openings 261 is spaced by a distance G2, and the distance G2 is in units of pixel size (i.e., in units of the size of a single pixel PX). In other words, light that simultaneously penetrates the first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 can be emitted outward from one of these openings 261 at a specific angle, while the remaining light is blocked by the barrier plate 260. Therefore, when a user views the display panel 210 at a first viewing angle VA1, only the light emitted toward the first viewing angle VA1 (i.e., the light emitted toward the first data lines dDL1, dDL2, dDL3…dDL… used to receive the first data signal) is emitted. N-3 The first image IG1 can be viewed by the user, so the display panel 210 can display the first image IG1 to the user. Conversely, when the user views the display panel 210 from a second viewing angle VA2, only the light rays emitted towards the second viewing angle VA2 (i.e., the second data lines dDL4, dDL5, dDL6…dDL…) can be seen by the user. N The second image IG2 can be viewed by the user, so the display panel 210 can display the second image IG2 for the user.

[0088] Please refer to the following: Figure 7 , Figure 7 This is a schematic diagram of the dual-view display device 300 according to the third embodiment of this disclosure. Figure 7 As shown, the dual-view display device 300 can provide a user with the ability to view a first image IG1 and a second image IG2 from different perspectives, and includes a display panel 310, a source driver module 320, a gate driver module 330, a timing control module 340, a backlight module (not shown separately), and a barrier plate (not shown separately). Except for the source driver module 320, all the aforementioned components / modules are the same as those corresponding to the components of the dual-view display device 100 in the first embodiment.
