Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a pixel driving architecture includes: a first in-plane data line 100; a dummy data line 500 is disposed between the first in-plane data line 100 and the second in-plane data line 200, and the first in-plane data line 100 and the second in-plane data line 200 are respectively connected to corresponding pixel units; the first-type driving chip 300, the first-type driving chip 300 is correspondingly connected with the first in-plane data lines 100 through first output data lines 310 respectively; the second driving chip 400, the second driving chip 400 is correspondingly connected to the dummy data line 500 and the second in-plane data line 200 in sequence through the second output data line 410.
Specifically, the in-plane data lines refer to data lines that transmit driving signals output from driving chips (i.e., the first type of driving chip and the second type of driving chip) to corresponding pixel units, and the data lines connected to the pixel units are divided into first in-plane data lines 100 and second in-plane data lines 200 according to the type of driving control chip for supplying the driving signals thereto. In a display panel, a substrate is often provided with scan lines arranged along a first direction and in-plane data lines (i.e., a first in-plane data line 100 and a second in-plane data line 200) arranged along a second direction, and a plurality of pixel units arranged in an array are defined at insulated intersections of the scan lines and the in-plane data lines. Wherein, the Array substrate line drive (GOA) circuit is connected with the scanning line to provide scanning signals for the pixel unit; the first driving chip 300 is connected to the first in-plane data line 100 through a first output data line 310, and the second driving chip 400 is connected to the second in-plane data line 200 through a second output data line 410 to provide driving data signals for the pixel unit, so as to display a corresponding image on the display panel.
In a conventional Full High Definition (FHD, resolution is 1920 × 1080) liquid crystal display panel, in order to achieve a good display effect, a flip-pixel (flip-pixel) frame is often used between an in-plane data line and a pixel unit, so that the number of the in-plane data lines in the Full High Definition liquid crystal display panel is one more than that of pixel columns, and if a driving chip of the same type is used to drive the pixel unit, one in-plane data line cannot receive a corresponding driving data signal, and thus, the driving chip in the Full High Definition liquid crystal display panel includes a first type driving chip and a second type driving chip. Because the number of the output signals of the first type of driving chip is inconsistent with the number of the output signals of the second type of driving chip, the output polarities of the corresponding first type of driving chip and the corresponding second type of driving chip in the horizontal direction are also inconsistent, so that the corresponding horizontal polarity at the junction of the first type of driving chip and the second type of driving chip is discontinuous, and stripes are generated when the pixel unit displays. The virtual data line is inserted between the in-plane data line corresponding to the first type of driving chip and the in-plane data line corresponding to the second type of driving chip, the second in-plane data line corresponding to the junction of the first in-plane data line and the second in-plane data line is connected with the virtual data line, the inserted virtual data line cannot drive the pixel unit, and output signals with discontinuous horizontal polarities are suspended, so that the polarities of the output signals driven by the pixel unit in the horizontal direction skip the second output data line connected with the virtual output data line, continuous polarities are formed in the horizontal direction, stripes at the position during display are avoided, and the display driving effect is better compared with the traditional pixel driving method.
Referring to fig. 1, in one embodiment, the number of dummy data lines 500 is two. Specifically, in the present embodiment, the polarities of the driving signals output by the first driving chip 300 are repeatedly arranged by taking "+ - - +" as a unit, so that the color shift problem can be effectively avoided. The output driving signals of the driving chips 300 of the first kind are integer multiples of four, that is, the polarities of the driving signals output by the driving chips 300 of the first kind in the horizontal direction can be kept continuous. However, due to the inverted pixel architecture, the number of the in-plane data lines is one more than that of the pixel columns, and the number of the driving signals output by the corresponding second driving chip 400 should be more than that of the driving signals output by the first driving chip 300, so that each pixel unit can be ensured to have a corresponding driving signal input. At this time, in order to ensure that the polarities of the second type of driving chip 400 and the first type of driving chip 300 in the horizontal direction are consistent (i.e. the polarities in the horizontal direction are continuous), two dummy data lines 500 are inserted between the first in-plane data line 100 and the second in-plane data line 200, under normal conditions, the horizontal polarity corresponding to the driving signal output by the second type of driving chip 400 is "+ - + + … …", while the horizontal polarity of the first type of driving chip 300 adjacent to the second type of driving chip 400 is "+ - +", in order to make the polarity in the horizontal direction consistent with that of the first type of driving chip 300, i.e. the polarity of the water in the second type of driving chip 400 adjacent to the first type of driving chip 300 is also "+ - +", the second output data line 410 corresponding to the horizontal polarity "- +" closer to the first type of driving chip 300 in the output signal of the second type of driving chip 400 is divided into two The driving signals corresponding to the "- +" polarity are short-circuited, respectively, to the dummy data lines 500. Therefore, the output signals of the first driver chip 300 and the second driver chip 400 have a horizontal polarity of "+ - - +" + - + + … … ", thereby ensuring the continuous horizontal polarity.
In one embodiment, the number of the first type driver chips 300 is two or more, and the number of the second type driver chips 400 is one. In particular, in different display panels, the number of the driving chips for providing the driving data signals to the pixel units is not unique due to the inconsistency of the number and arrangement form of the pixel units, so that in different types of display panels, the number of the driving chips is not unique. In addition, in the inverted pixel architecture, due to the arrangement of the driving inversion manner, the number of the in-plane data lines is one more than that of the pixel columns, and further, the types of the driving chips providing the driving signals for the pixel units may also be inconsistent, that is, the number of the driving signals output by the first type driving chip 300 is inconsistent with the number of the driving signals output by the second type driving chip 400. In one embodiment, the number of output data corresponding to the second type driver chip 400 is greater than the number of output data corresponding to the first type driver chip 300, a portion of the second output data lines 410 corresponding to the second type driver chip 400 is correspondingly connected to the dummy data lines 500, output signals corresponding to polarity discontinuity are output through the dummy data lines 500, the driving of the pixel unit is not performed, and the output signals for driving the pixel unit are kept continuous between the first type driver chip 300 and the second type driver chip 400, so as to avoid the generation of stripes.
It should be noted that referring to fig. 2, in one embodiment, the number of the first type driver chips 300 is 5. Specifically, the number of the first driving chips 300 is 5, and the polarities in the horizontal direction corresponding to the driving signals of each first driving chip 300 are repeatedly arranged by taking "+ - - - +" as a unit, so that the continuous horizontal polarities in the first direction are ensured. The number of the output signals of the second driving chip 400 is different from that of the first driving chip 300, and the second output data lines 410 adjacent to and corresponding to the horizontal polarity are connected to the dummy data lines 500 by connecting the dummy data lines 500, so that the continuity of the polarity is maintained in the horizontal direction.
Further, in one embodiment, each of the first type driver chips 300 corresponds to 960 pieces of first output data lines 310 and 966 pieces of second output data lines 410. Specifically, in the full-high-definition liquid crystal display panel, 960 driving signals are output by the first type driving chip 300, and each driving signal is transmitted to the first in-plane data line 100 through one first output data line 310 to drive the corresponding pixel unit; the number of the driving signals output by the second type driving chip 400 is 966, but the number of the corresponding second on-surface data lines 200 is only 961, if the conventional second output data lines 410 are directly and correspondingly connected with the second on-surface data lines 200, and the rest of the second output data lines 410 which are not connected with the second on-surface data lines 200 are directly suspended, the corresponding 5 output driving signals do not drive the pixel units, which may cause the display to be easily striped. Referring to fig. 3, the second output data line 410 far from the junction of the first in-plane data line 100 and the second in-plane data line 200 is sequentially a second output data line S966, a second output data line S965, a second output data line S964 … … to a second output data line S1, and the second in-plane data line 200 in the same direction is sequentially a second in-plane data line D961, a second in-plane data line D960, a second in-plane data line D959 … … to a second in-plane data line D1; to avoid the occurrence of stripes, two dummy data lines 500(dummy) are inserted between the second in-plane data line D961 and the first in-plane data line 100, the second output data line S966 and the second output data line S965 are respectively connected to the dummy data lines 500, the second output data line S964 is connected to the second in-plane data line D961, and the second output data line 410 and the second in-plane data line 200 are respectively connected in an interleaved manner. By the above method, the driving signals output by the second type driving chip 400 through the second output data line 410 are kept continuous in the horizontal direction.
It should be noted that, in one embodiment, after the second output data line 410 is sequentially connected to the dummy data line 500 and the second on-plane data line 200, the remaining second output data line 410 is left floating. Similarly, for example, the number of the first output data lines 310 is 960, and the number of the second output data lines 410 is 966, the second output data lines S966 and S965 are respectively connected to the dummy data line 500, the second output data line S964 is connected to the second in-plane data line D961, the second output data line S963 is connected to the second in-plane data line D960, until the second output data line S4 is connected to the second in-plane data line D1, the remaining second output data line S3, the second output data line S2 and the second output data line S1 are directly floating, and no connection is made, i.e., the corresponding output driving signal will not drive the pixel unit, thereby ensuring the corresponding connection between one second output data line 410 and one second in-plane data line 200, and completing the effective driving of all the pixel units.
In one embodiment, referring to fig. 2, the pixel driving structure further includes a logic board 600, and the first driving chip 300 and the second driving chip 400 are respectively connected to the logic board 600.
The logic board 600 is used for converting L VDS (low Voltage Differential Signaling) image input signals (including RGB data signals, clock signals and Control signals) transmitted by a digital board into L VDS signals capable of driving a liquid crystal screen after being processed by the logic board 600, and then transmitting the signals to L VDS receiving chips of the liquid crystal screen, and it should be noted that, in one embodiment, taking a full-high-definition liquid crystal display panel as an example, the first type driving chip 300 includes a first type driving chip S1, a first type driving chip S2, a first type driving chip S3, a first type driving chip S4, a first type driving chip S5 and a second type driving chip S6, wherein the TCON uses a second port Differential signal interface to transmit first type driving chip S39300 and second type driving chip S L, first type driving chip S5838, first type driving chip S5 and second type driving chip S6 to output corresponding VDS driving chips of the first type driving chip S638, the first type driving chip S6326 and the second type driving chip S2 and then the second driving chip S2 and the VDS 6 transmit corresponding driving signals to the first type driving chip S2 and then output corresponding VDS driving chip.
