Description

Display panel

The invention relates to an electronic device, and more particularly to a display panel.

In order to meet the needs of various shapes of electronic devices, the display panel needs to connect the horizontal scan lines through the vertical auxiliary circuit so that the scan signal and the data signal are input from the same side of the display panel. However, in the case of pre-charging, such a design structure will cause some sub-pixels to produce grayscale variation due to the influence of capacitive coupling, which makes the picture performance poor. For example, in a case where the precharge is one-stage, the switching elements in the N+1th row are turned on before the switching elements in the Nth row are turned off. If the auxiliary circuit electrically connected to the Nth row passes through a plurality of sub-pixels in the N+1th row, the potential of the plurality of sub-pixels is pulled down when the switching element in the Nth row is turned off, and The potentials of the plurality of sub-pixels are pulled down again when the switching element in the N+1th horizontal row is turned off, causing the brightness of the plurality of sub-pixels to be the same as those of other sub-pixels in the N+1th horizontal row. The brightness is different.

FIG. 1 schematically shows that each first scan line SL1 and a corresponding second scan line SL2 are electrically connected through a fourth auxiliary line AL4. However, in other embodiments, each first scan line SL1 and a corresponding second scan line SL2 may be electrically connected through more than one fourth auxiliary line AL4. By increasing the number of the fourth auxiliary line AL4, it helps to reduce the impedance and improve the uniformity of the display image.

The first auxiliary line AL1 is electrically connected to the first scan line SL1, the third auxiliary line AL3 is electrically connected to the first auxiliary line AL1 and the second auxiliary line AL2, and the fourth auxiliary line AL4 connects the first scan line SL1 and the corresponding The second scan line SL2 is electrically connected, and the scan signal has two transmission paths before being transmitted to the third auxiliary line AL3 (including the first part P1 of the first auxiliary line AL1 and the third part P3 of the second auxiliary line AL2) , The two transmission paths are combined by the third auxiliary line AL3 into one transmission path (the first part P1 between the third auxiliary line AL3 and the first scan line SL1 in the second direction D2), and the one transmission path is then It is divided into two transfer paths (including the first scan line SL1 and the second scan line SL2) by the fourth auxiliary line AL4. In this way, two adjacent second rows R2 (such as the second row R2-1 and the second row R2-2) can receive the scan signal at the same timing. By combining the above circuit design with the signal input of the first data line DL1 and the second data line DL2 (the data signal is sequentially output along the first direction D1 to the alternately arranged first data line DL1 and second data line DL2), The driving mode of two data lines and half gate line (two data lines and half gate line, 2DHG) can be realized.

For the convenience of description, the union of the second row R2-1 and the second row R2-2 is hereinafter referred to as the first unit, and the union of the second row R2-3 and the second row R2-4 is hereinafter referred to as the second unit. And the union of the second row R2-5 and the second row R2-6 is hereinafter referred to as the third unit. The display panel 1 may include more units as required, and these units are sequentially arranged along the direction opposite to the second direction D2. In addition, the pre-charging is one-stage means that the switching element (active element SP1) in the i+1th unit is turned on before the switching element in the i+th unit is turned off, and the switching element in the i+2th unit is in the i+th unit. The switch element in the unit turns on only after it is turned off, and i is a positive integer. Taking i equal to 1 as an example, when the pre-charging is one-stage, the switching element in the second unit is turned on before the switching element in the first unit is turned off, while the switching element in the third unit is in the first unit The switch element in is turned off before turning on. Precharging to the second order means that the switching elements in the i+1th unit and the switching elements in the i+2th unit are turned on sequentially before the switching elements in the i+th unit are turned off (the ratio of the switching elements in the i+1th unit The switching element in the i+2th unit is turned on first), and the switching element in the i+3th unit is turned on after the switching element in the i-th unit is turned off. Taking i equal to 1 as an example, when the pre-charging is two-stage, the switching elements in the second unit and the switching elements in the third unit are turned on in sequence before the switching elements in the first unit are turned off, and the fourth unit (Not shown in FIG. 1, for example, the combination of the second row R2-7 and the second row R2-8 in FIG. 2) The switching elements in the first unit are turned on only after the switching elements in the first unit are turned off. The case of precharging to third-order or higher can be deduced by analogy.

In the case of the first-level pre-charging, the switching element in the second unit is turned on before the switching element in the first unit is turned off. If the auxiliary circuit that transmits signals (such as scanning signals) in the first unit passes through the second unit A plurality of sub-pixels SP, for example, the auxiliary circuit of the first unit extends from the area between the plurality of sub-pixels SP to above the scan line corresponding to the first unit, then the potential of the plurality of sub-pixels SP (such as The potential of the pixel electrode SP2) is pulled down when the switching element of the first cell is turned off, and the potential of the plurality of sub-pixels is pulled down again when the switching element of the second cell is turned off, resulting in the plurality of sub-pictures The brightness of the pixel SP is different from the brightness of other sub-pixels SP in the second unit.

If the third auxiliary line AL3 and the fourth auxiliary line AL4 are not provided, and the third portion P3 of the second auxiliary line AL2 extends to the second scan line SL2 and is electrically connected to the second scan line SL2 through the conductive via (ie The scan signal is independently transmitted to the first scan line SL1 and the second scan line SL2) through the first part P1 of the first auxiliary line AL1 and the third part P3 of the second auxiliary line AL2), and is precharged to a first-level In this case, since the first part P1 of the first auxiliary line AL1 electrically connected to the first unit passes through the middle two sub-pixels SP of the second row R2-3 and the middle two sub-pixels SP of the second row R2-4 , And the third part P3 of the second auxiliary line AL2 electrically connected to the first unit passes through the two right sub-pixels SP of the second row R2-3 and the right two sub-pixels SP of the second row R2-4, Therefore, the brightness of the eight sub-pixels SP in the second unit will be affected by capacitive coupling different from the brightness of the remaining four sub-pixels SP in the second unit.

In contrast, by setting the third auxiliary line AL3 and the fourth auxiliary line AL4, and the third part P3 of the second auxiliary line AL2 electrically connected to the i-th unit (such as the first unit) does not pass through the i+1-th unit The design of one or more sub-pixels SP (such as the second unit) can reduce the number of sub-pixels SP affected by capacitive coupling when pre-charged to the first order, such as avoiding the second row R2-3 The two right sub-pixels SP of the right side of R2-4 and the right two sub-pixels SP of the second row R2-4 are affected by capacitive coupling.

According to the above design, when the precharge is n-stage, there will be at least n units between the third auxiliary line AL3 and the first scan line SL1 electrically connected to it, that is, each third auxiliary line AL3 is electrically connected to it There are at least 2n second rows R2 between the first scan lines SL1, and there are at least 2n+1 second rows R2 between each third auxiliary line AL3 and the second scan line SL2 electrically connected to it, where n is Positive integer. FIG. 1 schematically shows a circuit design with a first-level pre-charge, in which there are two second rows R2 between each third auxiliary line AL3 and the first scan line SL1 electrically connected to it, and each third auxiliary line AL3 There are at least three second rows R2 between the line AL3 and the second scan line SL2 electrically connected to it. However, in other embodiments, under a first-level precharge architecture, there may also be more than two (such as three, four) between each third auxiliary line AL3 and the first scan line SL1 electrically connected to it. Or more) of the second row R2, and there may be more than 3 (such as 4, 5 or more) between each third auxiliary line AL3 and the second scan line SL2 electrically connected to it The second row is R2.

Compared with the green sub-pixel G, the human eye has a lower perception of the brightness (or gray scale) variation of the red sub-pixel R or the blue sub-pixel B. Therefore, in some embodiments, the at least one first auxiliary line AL1 passing through the second unit can be arranged between the red row and the adjacent blue row to prevent the coupling effect from affecting human eyes. It is easy to perceive the green sub-pixel G whose brightness (or gray scale) varies. In addition, since the third part P3 (the part that transmits the scan signal) of the second auxiliary line AL2 does not pass through the sub-pixel SP in the second unit, it is possible to arrange at least one second auxiliary line AL2 in the green row and phase. Between the adjacent blue rows to prevent the green sub-pixel G from being affected by capacitive coupling. Alternatively, at least one second auxiliary line AL2 can be arranged between the green row and the adjacent red row to prevent the green sub-pixel G from being affected by the capacitive coupling. In addition, since the two sub-pixels SP located on the adjacent sides of the fourth auxiliary line AL4 in the first direction D1 may be affected by the coupling effect, at least one of the fourth auxiliary lines AL4 can be arranged in a red row. Between the adjacent blue row to prevent the coupling effect from affecting the green sub-pixel G whose grayscale variation is easier for human eyes to perceive.

In some embodiments, the second part P2 of the first auxiliary line AL1 may overlap with at least one fourth auxiliary line AL4 in the third direction D3, and the second part P2 is electrically connected to the at least one fourth auxiliary line AL4. insulation. By overlapping the second portion P2 of the first auxiliary line AL1 on at least one fourth auxiliary line AL4, a shielding effect can be provided, which helps to improve the display quality.

In some embodiments, the plurality of fourth auxiliary lines AL4 may be arranged in a staggered arrangement. The misalignment arrangement means that multiple fourth auxiliary lines AL4 can be distributed in an irregular manner (see FIG. 3) in an array formed by multiple sub-pixels SP, instead of being regularly distributed on multiple sub-pixels SP. Into the array. With the design of the dislocation arrangement, the Moire pattern phenomenon caused by the periodic structure can be avoided, and the human eye's perception of grayscale variation can be reduced.

According to different requirements, the display panel 1 may further include other elements or film layers. For example, the display panel 1 may further include a plurality of fifth auxiliary lines AL5. At least one of the plurality of fifth auxiliary lines AL5 is located in the array formed by the plurality of sub-pixels SP.
