Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a display panel, a driving method thereof and a display device. BACKGROUND

[0002] With the development of science and technology, the liquid crystal display (LCD) has become a mainstream technology in the display field due to its thin body, power saving and no radiation. The liquid crystal itself in the liquid crystal display does not emit light, and needs to rely on an external light source, for example, a backlight module, to provide a light source for display.

[0003] The conventional liquid crystal display usually adopts a pure white light source as a light emitting source of the backlight module. The pure white light source needs to be combined with a color filter to realize color display of the display device, which often causes the liquid crystal display to have problems such as unvibrant color performance and low energy utilization rate.

[0004] In order to solve the above problems, a red (R) chip, a green (G) chip and a blue (B) chip are introduced into the backlight module as color light sources, which is a new type of backlight module. However, in the current backlight module with color light sources, the R chip usually has a thermal decay problem, and the process of the R chip is complex and the cost is high, which limits the promotion and use of the backlight module with color light sources. SUMMARY

[0005] The present application provides a display panel, a driving method thereof and a display device. The area of the red sub-pixel, the area of the green sub-pixel and the area of the blue sub-pixel in each pixel unit are sequentially reduced, so that the light transmittance of the red sub-pixel is improved, the peak brightness is high, and the performance of the display panel and the display device is good.

[0006] In a first aspect, a display panel is provided. The display panel includes a plurality of pixel units arranged in an array. Each pixel unit includes a red sub-pixel, a green sub-pixel and a blue sub-pixel. The area of the red sub-pixel in each pixel unit is greater than the area of the green sub-pixel, and the area of the green sub-pixel is greater than the area of the blue sub-pixel.

[0007] Due to the above technical scheme, by setting the area of the red sub-pixel, the area of the green sub-pixel, and the area of the blue sub-pixel in each pixel unit to decrease in turn, the penetration rate of light passing through the red sub-pixel in a pixel unit can be improved due to the largest area ratio of the red sub-pixel, even if the red light chip of the backlight module used by the display panel has serious thermal decay, the display panel can still have high peak brightness, so that the final display quality of the display panel has higher matching degree of the number of outcoming light sub-pixels, and better coordination and matching of light can be brought. At the same time, since the human eye is most sensitive to green, by setting the area ratio of the green sub-pixel in a pixel unit to be smaller than that of the red sub-pixel and larger than that of the blue sub-pixel, the color restoration degree, brightness perception, and power consumption efficiency of the display panel can be optimized.

[0008] In some embodiments, the ratio of the area of the red sub-pixel, the area of the green sub-pixel, and the area of the blue sub-pixel in each pixel unit is 1.3-1.7: 0.8-1.2: 0.3-0.7.

[0009] In the above technical scheme, by setting the area of the red sub-pixel, the area of the green sub-pixel, and the area of the blue sub-pixel in each pixel unit to decrease in turn and be within a suitable range, the penetration rate of light passing through the red sub-pixel in a pixel unit can be improved by increasing the area ratio of the red sub-pixel due to the largest area ratio of the red sub-pixel, even if the red light chip of the color light-emitting backlight module used by the display panel has serious thermal decay, the display panel can still have high peak brightness, so that the final display quality of the display panel has higher matching degree of the number of outcoming light sub-pixels, and better coordination and matching of light can be brought. At the same time, since the human eye is most sensitive to green, by setting the area ratio of the green sub-pixel in a pixel unit to be slightly larger, the color restoration degree, brightness perception, and power consumption efficiency of the display panel can be optimized. In addition, the area structure design within a suitable range can also realize an ultra-small pitch module, so that the pitch between sub-pixels and even between pixel units can be reduced, further expanding the application scenarios of the display panel.

[0010] In some embodiments, the display panel further includes a plurality of data lines, the green sub-pixel and the blue sub-pixel in each pixel unit are connected to a first data line, and the red sub-pixel is connected to a second data line, the first data line and the second data line are different; The display panel further includes a plurality of gate lines, the extension direction of the gate lines is perpendicular to the extension direction of the data lines; The gate line connected to the red sub-pixel, the gate line connected to the green sub-pixel, and the gate line connected to the blue sub-pixel in each pixel unit are different gate lines; Or, the red sub-pixel and the green sub-pixel in each pixel unit are connected with the first gate line, and the blue sub-pixel is connected with the second gate line. Or, the red sub-pixel and the green sub-pixel in each pixel unit are connected with the first gate line, and the blue sub-pixel is connected with the second gate line.

[0011] In the technical solution, the red sub-pixel and the green sub-pixel in one pixel unit are connected with the same first data line, and the blue sub-pixel is connected with the second data line different from the first data line, so that compared with the related art in which the red sub-pixel, the green sub-pixel and the blue sub-pixel in each pixel unit are respectively connected with the data lines, the number of data lines is reduced by 1 / 3, the use amount of the chip on film electrically connected with the data lines is reduced, and the cost is reduced.

[0012] In some embodiments, the display panel further includes a plurality of data lines, the red sub-pixel and the green sub-pixel in each pixel unit are connected with the first data line, and the blue sub-pixel is connected with the second data line, the first data line is different from the second data line. The display panel further includes a plurality of gate lines, and the extension direction of the gate lines is perpendicular to the extension direction of the data lines. The gate line connected with the red sub-pixel, the gate line connected with the green sub-pixel and the gate line connected with the blue sub-pixel in each pixel unit are different gate lines. Or, the blue sub-pixel and the green sub-pixel in each pixel unit are connected with the first gate line, and the red sub-pixel is connected with the second gate line. Or, the red sub-pixel and the green sub-pixel in each pixel unit are connected with the first gate line, and the blue sub-pixel is connected with the second gate line.

[0013] In the technical solution, the red sub-pixel and the green sub-pixel in one pixel unit are connected with the same first data line, and the blue sub-pixel is connected with the second data line different from the first data line, so that compared with the related art in which the red sub-pixel, the green sub-pixel and the blue sub-pixel in each pixel unit are respectively connected with the data lines, the number of data lines is reduced by 1 / 3, the use amount of the chip on film electrically connected with the data lines is reduced, and the cost is reduced.

[0014] In some embodiments, the display panel further includes a plurality of data lines, the red sub-pixel and the green sub-pixel in each pixel unit are connected with the first data line, and the blue sub-pixel is connected with the second data line, the first data line is different from the second data line. The display panel further includes a plurality of gate lines, and the extension direction of the gate lines is perpendicular to the extension direction of the data lines. The gate line connected with the red sub-pixel, the gate line connected with the green sub-pixel and the gate line connected with the blue sub-pixel in each pixel unit are different gate lines. Alternatively, the red sub-pixel and the green sub-pixel in each pixel unit are connected to the first gate line, and the blue sub-pixel is connected to the second gate line. Alternatively, the green sub-pixel and the blue sub-pixel in each pixel unit are connected to the first gate line, and the red sub-pixel is connected to the second gate line.

[0015] In the technical solution, the red sub-pixel and the blue sub-pixel in one pixel unit are connected to the same first data line, and the green sub-pixel is connected to a second data line different from the first data line. Compared with the related art in which the red sub-pixel, the green sub-pixel, and the blue sub-pixel in each pixel unit are respectively connected to respective data lines, the number of data lines is reduced by 1 / 3, the use amount of the chip on film electrically connected to the data lines is reduced, and the cost is reduced.

[0016] In some embodiments, the red sub-pixel in each pixel unit is connected to two gate lines.

[0017] In the technical solution, the charging time of the red sub-pixel is longer than the charging time of the green sub-pixel and the charging time of the blue sub-pixel in the process of driving the display panel.

[0018] In some embodiments, in each pixel unit, the red sub-pixel is in the shape of a rectangle, the green sub-pixel and the blue sub-pixel are located on one side of the width direction of the rectangle, and the green sub-pixel and the blue sub-pixel are arranged along the length direction of the rectangle.

[0019] In the technical solution, the green sub-pixel and the blue sub-pixel are located on either side of the width direction of the red sub-pixel and in the same column / row. The spatial position not only enables the green sub-pixel and the blue sub-pixel in one pixel unit to be connected to the same data line, but also reduces the number of data lines by 1 / 3 compared with the related art in which the red sub-pixel, the green sub-pixel, and the blue sub-pixel in each pixel unit are respectively connected to respective data lines, greatly reduces the cost of the chip on film connected to the data lines, reduces the cost of the display panel, and is conducive to simplifying the driving architecture of the display panel. In addition, an ultra-small pitch can be achieved, the pitch between the sub-pixels and even the pixel units is reduced, and the application scenarios of the display panel are expanded.

[0020] In a second aspect, a driving method of a display panel is provided. The display panel includes a plurality of pixel units arranged in an array. Each pixel unit includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel. The area of the red sub-pixel in each pixel unit is greater than the area of the green sub-pixel, and the area of the green sub-pixel is greater than the area of the blue sub-pixel. The driving method of the display panel includes the following steps. In the process of driving the display panel, the charging duration of the red sub-pixel is controlled to be greater than the charging duration of the green sub-pixel and the charging duration of the blue sub-pixel, respectively.

[0021] As such, in the technical solution, by controlling the charging duration of the red sub-pixel to be greater than the charging duration of the green sub-pixel and the charging duration of the blue sub-pixel in the process of driving the display panel, the charging efficiency of the large-size red sub-pixel can be improved, the liquid crystal capacitor corresponding to the red sub-pixel can reach the target voltage as much as possible, and the liquid crystal molecules can be deflected by a sufficient angle, so that the brightness of the three primary colors is balanced, the display panel displays a stable picture, and the performance is good.

[0022] In a third aspect, a display device is provided, which includes a backlight module and the display panel or the display panel driven by the driving method of the display panel.

[0023] As such, in the technical solution, by controlling the charging duration of the red sub-pixel to be greater than the charging duration of the green sub-pixel and the charging duration of the blue sub-pixel in the process of driving the display panel, the charging efficiency of the large-size red sub-pixel can be improved, the liquid crystal capacitor corresponding to the red sub-pixel can reach the target voltage as much as possible, and the liquid crystal molecules can be deflected by a sufficient angle, so that the brightness of the three primary colors is balanced, the display panel displays a stable picture, and the performance is good.

[0024] In some embodiments, the backlight module is arranged on the backlight side of the display panel, and the backlight module is configured to provide a color light source for the display panel.

[0025] In the technical solution, the color light emitted by the backlight module can enter the display panel and improve the penetration rate after passing through the red sub-pixel, so that even if the red light chip in the backlight module emitting color light is severely attenuated, the display device can still have high peak brightness, so that the final display quality of the display device has higher matching degree of the number of emitted photons, and better coordination and matching of light can be brought about. At the same time, since the human eye is most sensitive to green, by setting the area ratio of the green sub-pixel in a pixel unit to be less than that of the red sub-pixel but greater than that of the blue sub-pixel, the color reproduction, brightness perception, and power consumption efficiency of the display device can be optimized, and the performance of the display device is good.

[0029] In this paper, the reference to "embodiments" means that the specific features, structures or properties described in conjunction with the embodiments can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily mean the same embodiment, nor is it an independent or alternative embodiment to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments in any suitable manner.

[0030] Display devices are used to present images and information, etc., and have a wide range of applications in modern society, such as electronic devices, display screens, etc. With the continuous progress of technology, people have increasingly high requirements for the performance of display devices, including higher resolution, thinner thickness, lower power consumption, etc. In this context, LCDs have emerged, and liquid crystal display devices have gradually become a mainstream technology in the display field due to their thin body, power saving, and no radiation, etc. Liquid crystal display devices present images and information by utilizing the deflection of liquid crystals, but liquid crystals themselves do not emit light and need to rely on external light sources to display. Backlight modules are key components for providing light sources for liquid crystal display devices, and are used to enable liquid crystal display devices to normally display clear and bright images.

[0031] Traditional liquid crystal display devices usually use pure white light sources as the light-emitting source of the backlight module, such as common white light-emitting diode (LED) light-emitting sources. Such pure white light-emitting sources need to be combined with color filters to enable the display device to achieve color display, i.e., at least three color filters of red, green, and blue are used to decompose white light into three primary color lights, and then the intensity and proportion of the three primary color lights are controlled to present various colors. However, this approach often has problems such as insufficient color vividness and low energy utilization rate.

[0032] To overcome these problems, R chips, green G chips, and blue B chips are introduced as color light sources in the backlight module. The R chips, G chips, and B chips can directly emit red, green, and blue three primary color lights without the need for light decomposition through color filters, so that the presentation of colors can be more accurately controlled, the accuracy and saturation of colors can be improved, and the color gamut and energy efficiency of liquid crystal display devices, such as liquid crystal televisions, can be improved, the energy utilization efficiency can be improved, and the demand for higher quality display can be met.

[0033] However, in the backlight module using R chips, G chips, and B chips as color light sources, the R chips have a problem of thermal decay, which greatly limits the brightness improvement of the liquid crystal display device. Moreover, the total cost of the R chips, G chips, and B chips is higher than the total cost of the combination of B chips and quantum dots (QDs), and the economic problem will also limit the market expansion of the backlight module using RGB chip color light sources. Among them, the R chip has a complex process and a cost much higher than that of the G chip and the B chip, which is the main bottleneck of the cost problem.

[0034] Figure 1 A curve diagram showing the change of the brightness of the R chip, the G chip, and the B chip according to some embodiments of the present application with temperature. In the curve diagram, Figure 1 the abscissa represents the ambient temperature in ℃, and the ordinate represents the brightness in a.u. From the curve diagram, Figure 1It can be seen that the R chip is particularly sensitive to temperature as the ambient temperature increases, for example, when the ambient temperature increases from 25 DEG C to 85 DEG C, the brightness of the R chip decreases by about 30%, which not only causes color point drift, but also affects the brightness specification of the display device. Therefore, in order to maintain a high brightness specification, a backlight module using RGB color light sources generally sets more R chips to compensate for the thermal decay, which results in higher cost.

[0035] In addition, the display device further includes a display panel, the display panel is provided with a plurality of sub-pixels arranged in an array, and each color chip in the backlight module is correspondingly arranged with a sub-pixel of the same color. Figure 2 FIG. 1 is a structural schematic diagram of R, G and B sub-pixels of a display panel according to the related art. As shown in FIG. 1, the display panel according to the related art usually uses R, G and B sub-pixels with the same area, and the R, G and B sub-pixels are arranged in a row. Figure 2 As shown in FIG. 1, the display panel according to the related art usually uses R, G and B sub-pixels with the same area, and the R, G and B sub-pixels are arranged in a row. The display panel using such a sub-pixel arrangement usually has the above-mentioned problems, i.e., the performance of the display panel is deteriorated due to the thermal decay of the R chip of the backlight module.

[0036] On the basis of the above, the display panel and the specific type of the display device using the same are not limited in the embodiments of the present application. The display panel can have various implementation manners, for example, it can be a television, an augmented reality (AR) glasses, a virtual reality (VR) glasses, a projector, a head-up display (HUD), a digital car lamp or an embedded image display, etc.

[0037] In order to further understand the technical solutions of the display panel, the driving method thereof and the display device, and how the technical solutions solve the above-mentioned technical problems, the following will describe the technical solutions in combination with some specific embodiments and the accompanying drawings. Each embodiment can be combined with each other, and the same or similar concepts or processes can not be described in some embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments.

[0038] The display panel provided by the embodiments of the present application can include a plurality of pixel units arranged in an array, each pixel unit including a red sub-pixel 11, a green sub-pixel 12 and a blue sub-pixel 13, the area of the red sub-pixel 11 being greater than the area of the green sub-pixel 12, and the area of the green sub-pixel 12 being greater than the area of the blue sub-pixel 13. Figures 3 to 9

[0039] ​In practical applications, the aforementioned display panels may include liquid crystal display panels and other display panels that cannot emit light actively and require a backlight module. Taking a liquid crystal display panel as an example, the liquid crystal display panel can be paired with a backlight that emits colored light to achieve display.

[0040] In this application embodiment, the pixel unit refers to the main overall structure of the pixel. The number of red sub-pixels 11, green sub-pixels 12, and blue sub-pixels 13 in each pixel unit of the liquid crystal display panel is not specifically limited; each pixel unit can have one or more of these sub-pixels. Figure 3 and applications Figure 3 of Figure 4 , Figure 5 and applications Figure 5 of Figures 6 to 9 The illustrations and explanations are based on the example of one unit containing red sub-pixels 11, green sub-pixels 12, and blue sub-pixels 13.

[0041] The shapes of red sub-pixels 11, green sub-pixels 12, and blue sub-pixels 13 can be rectangles, squares, etc. When the shapes of red sub-pixels 11, green sub-pixels 12, and blue sub-pixels 13 are all rectangles, it is further set that the rectangles of red sub-pixels 11, green sub-pixels 12, and blue sub-pixels 13 have the same shape along the second direction (…). Figures 5 to 9 Based on this, the ratio of the areas of red sub-pixel 11, green sub-pixel 12, and blue sub-pixel 13 along the first direction (ox direction) is also the ratio of their areas along the first direction (ox direction). Figures 5 to 9 The ratio of the area to the length in the oy direction. This consistent ratio of area and length allows sub-pixels to form a well-coordinated size relationship, resulting in better visual lighting effects.

[0042] It should be noted that the ox direction and the oy direction can intersect, and furthermore, the ox direction and the oy direction can be perpendicular. Figures 3 to 9 The diagram is illustrated using the example where the ox direction is perpendicular to the oy direction.

[0043] The display panel provided by the embodiments of the present application has the area of the red sub-pixel, the area of the green sub-pixel, and the area of the blue sub-pixel in each pixel unit decreasing in turn. At this time, since the area of the red sub-pixel in one pixel unit accounts for the largest proportion, the light transmittance can be improved. Even if the red light chip of the backlight module used by the display panel has serious thermal decay, the display panel can still have relatively high peak brightness, so that the final display quality of the display panel has higher matching degree of the number of outgoing light sub-pixels, and better coordination and matching of light can be brought. At the same time, since the human eye is most sensitive to green, by setting the area of the green sub-pixel in one pixel unit to be less than the area of the red sub-pixel and greater than the area of the blue sub-pixel, the color restoration degree, brightness perception, and power consumption efficiency of the display panel can be optimized, and the performance of the display panel is better.

[0044] In some embodiments, as shown in FIG. 1, the display panel provided by the embodiments of the present application has the area of the red sub-pixel 11, the area of the green sub-pixel 12, and the area of the blue sub-pixel 13 in each pixel unit decreasing in turn. Figures 3 to 9 The ratio of the area of the red sub-pixel 11, the area of the green sub-pixel 12, and the area of the blue sub-pixel 13 in the display panel provided by the embodiments of the present application is 1.3-1.7: 0.8-1.2: 0.3-0.7.

[0045] For example, the ratio of the area of the red sub-pixel 11, the area of the green sub-pixel 12, and the area of the blue sub-pixel 13 can be 1.3: 0.8: 0.3, 1.4: 0.9: 0.4, 1.5: 1: 0.5, 1.6: 1.1: 0.6, or 1.7: 1.2: 0.7, etc.

[0046] In addition, according to the embodiments of the present application, the total area of each pixel unit can be 80 μm x 130 μm, and the specific area of the red sub-pixel 11, the green sub-pixel 12, and the blue sub-pixel 13 can be adjusted within this area range.

[0047] The display panel provided by the embodiment of the present application has the area of the red sub-pixel, the area of the green sub-pixel, and the area of the blue sub-pixel in each pixel unit decreasing in turn and being within a proper range. At this time, the area ratio of the red sub-pixel is the largest in one pixel unit, the penetration rate of the light passing through the red sub-pixel can be improved by increasing the area ratio of the red sub-pixel, even if the red light chip in the backlight module used by the display panel has serious thermal decay, the display panel can still have relatively high peak brightness, the final display quality of the display panel has higher matching degree of the number of light sub-pixels, and better coordination and matching of light can be brought. At the same time, the human eye is most sensitive to green, the area ratio of the green sub-pixel in one pixel unit is slightly larger, the color restoration degree, brightness perception, and power consumption efficiency of the display panel can be optimized. In addition, the area structure design within a proper range can also realize an ultra-small pitch module, the pitch between the sub-pixels and even the pixel units can be reduced, and the application scenarios of the display panel are further expanded.

[0048] In some embodiments, as shown in FIG. 1, the display panel provided by the embodiment of the present application can further include a plurality of data lines (Data) and a plurality of gate lines (Gate). The data lines extend along the oy direction, the gate lines extend along the ox direction, and the oy direction is perpendicular to the ox direction. The data lines connected by the red sub-pixel 11, the green sub-pixel 12, and the blue sub-pixel 13 in each pixel unit are different, and the gate lines connected by the red sub-pixel 11, the green sub-pixel 12, and the blue sub-pixel 13 in each pixel unit are different.

[0051] The display panel provided by the embodiment of the present application is based on the differential design of the area of the red sub-pixel, the area of the green sub-pixel and the area of the blue sub-pixel, and further realizes the independent control of each sub-pixel by connecting the red sub-pixel, the green sub-pixel and the blue sub-pixel in each pixel unit to different gate lines and data lines, so as to ensure that no signal transmission error occurs, and the performance of the display panel is better.

[0052] In some embodiments, as shown in Figure 6 and Figure 7 、 Figure 9 The display panel provided by the embodiment of the present application can further include a plurality of data lines (Data) and a plurality of gate lines (Gate), the data lines extend along the oy direction, the gate lines extend along the ox direction, and the oy direction is perpendicular to the ox direction; the green sub-pixel 12 and the blue sub-pixel 13 in each pixel unit are connected to the first data line, and the red sub-pixel 11 is connected to the second data line, and the first data line and the second data line are different data lines.

[0053] In the embodiment of the present application, the red sub-pixel 11 is still driven by the 1G1D (1Gate+1Data) architecture, while the green sub-pixel 12 and the blue sub-pixel 13 are driven according to the data line sharing architecture (DLS). It should be noted that the DLS architecture requires an increase in the number of gate lines, which can control the two sub-pixels connected to the same data line to realize time-sharing conduction and data writing.

[0054] On the basis of the above, the gate line connected to the red sub-pixel 11, the gate line connected to the green sub-pixel 12 and the gate line connected to the blue sub-pixel 13 in each pixel unit of the display panel are all different gate lines; or, the red sub-pixel 11 and the green sub-pixel 12 in each pixel unit are connected to the first gate line, and the blue sub-pixel 13 is connected to the second gate line; or, the red sub-pixel 11 and the blue sub-pixel 13 in each pixel unit are connected to the first gate line, and the green sub-pixel 12 is connected to the second gate line.

[0055] The display panel provided in the embodiments of the present application is designed differently in the areas of the red sub-pixel, the green sub-pixel and the blue sub-pixel, and the green sub-pixel and the blue sub-pixel in one pixel unit are connected to the same first data line, while the red sub-pixel is connected to a second data line different from the first data line, so that compared with the related art in which the red sub-pixel, the green sub-pixel and the blue sub-pixel in each pixel unit are respectively connected to the data lines, the number of data lines is reduced by 1 / 3, the use of the chip-on-film electrically connected to the data lines is reduced, and the cost is reduced. In addition, the control over the rows of sub-pixels can be realized through various connection modes of the gate lines, and when two sub-pixels share one gate line (except that the green sub-pixel and the blue sub-pixel share the same gate line), the cost is further reduced.

[0056] In some embodiments, the display panel provided in the embodiments of the present application can further include a plurality of data lines (Data) and a plurality of gate lines (Gate), the data lines extend along the oy direction, the gate lines extend along the ox direction, and the oy direction is perpendicular to the ox direction; the red sub-pixel and the green sub-pixel in each pixel unit are connected to the first data line, and the blue sub-pixel is connected to the second data line, and the first data line is different from the second data line.

[0057] On the basis described above, the gate line connected to the red sub-pixel, the gate line connected to the green sub-pixel and the gate line connected to the blue sub-pixel in each pixel unit are different gate lines; or the red sub-pixel and the blue sub-pixel in each pixel unit are connected to the first gate line, and the green sub-pixel is connected to the second gate line; or the green sub-pixel and the blue sub-pixel in each pixel unit are connected to the first gate line, and the red sub-pixel is connected to the second gate line.

[0058] The display panel provided in the embodiments of the present application is designed differently in the areas of the red sub-pixel, the green sub-pixel and the blue sub-pixel, and the green sub-pixel and the blue sub-pixel in one pixel unit are connected to the same first data line, while the red sub-pixel is connected to a second data line different from the first data line, so that compared with the related art in which the red sub-pixel, the green sub-pixel and the blue sub-pixel in each pixel unit are respectively connected to the data lines, the number of data lines is reduced by 1 / 3, the use of the chip-on-film electrically connected to the data lines is reduced, and the cost is reduced. In addition, the control over the rows of sub-pixels can be realized through various connection modes of the gate lines, and when two sub-pixels share one gate line (except that the green sub-pixel and the blue sub-pixel share the same gate line), the cost is further reduced.

[0059] In some embodiments, as Figure 8As shown, the display panel provided by the embodiment of the present application can further include a plurality of data lines (Data) and a plurality of gate lines (Gate), the data lines extend along the oy direction, the gate lines extend along the ox direction, and the oy direction is perpendicular to the ox direction; the red sub-pixel 11 and the blue sub-pixel 13 in each pixel unit are connected to the first data line, and the green sub-pixel 12 is connected to the second data line, and the first data line is different from the second data line.

[0060] On the basis of the above, the gate line connected by the red sub-pixel 11, the gate line connected by the green sub-pixel 12, and the gate line connected by the blue sub-pixel 13 in each pixel unit are all different gate lines; or, the red sub-pixel 11 and the green sub-pixel 12 in each pixel unit are connected to the first gate line, and the blue sub-pixel 13 is connected to the second gate line; or, the green sub-pixel 12 and the blue sub-pixel 13 in each pixel unit are connected to the first gate line, and the red sub-pixel 11 is connected to the second gate line.

[0061] The display panel provided by the embodiment of the present application can reduce 1 / 3 of the number of data lines to reduce the use amount of the chip on film electrically connected to the data line, so as to achieve the purpose of reducing the cost, on the basis of the different design of the area of the red sub-pixel, the area of the green sub-pixel, and the area of the blue sub-pixel; in addition, the control of each row of sub-pixels can be realized through the connection mode of the plurality of gate lines, and the cost is further reduced when two sub-pixels share one gate line (except that the red sub-pixel and the blue sub-pixel share the same gate line).

[0062] In some embodiments, as shown, Figures 6 to 9 As shown, in the display panel provided by the embodiment of the present application, in each pixel unit, the shape of the red sub-pixel is a rectangle, the green sub-pixel and the blue sub-pixel are located on one side of the width direction of the rectangle, and the green sub-pixel and the blue sub-pixel are further arranged along the length direction of the rectangle.

[0063] It should be understood that the green sub-pixel and the blue sub-pixel are located on one side of the width direction of the rectangle, which means that the green sub-pixel and the blue sub-pixel are located on the left side of the width direction of the rectangle, or the green sub-pixel and the blue sub-pixel are located on the right side of the width direction of the rectangle, and the specific application is subject to the actual application.

[0064] In addition, the embodiment of the present application does not make specific limitation on the arrangement position of the green sub-pixel and the blue sub-pixel along the length direction of the rectangle.

[0065] The display panel provided in the embodiments of the present application is designed differently in the areas of the red sub-pixel, the green sub-pixel and the blue sub-pixel. The green sub-pixel and the blue sub-pixel are located on either side of the red sub-pixel in the width direction and in the same column / row. The spatial position placement can well connect the green sub-pixel and the blue sub-pixel in a pixel unit to the same data line, thereby reducing the number of data lines by 1 / 3, greatly reducing the cost of the chip-on-film connected to the data line, thereby reducing the cost of the display panel and facilitating the simplification of the driving architecture of the display panel. In addition, the structure design can also realize an ultra-small pitch, so as to reduce the pitch between the sub-pixels and even the pixel units, thereby expanding the application scenarios of the display panel.

[0066] The embodiments of the present application further provide a display panel driving method, which is suitable for any one of the display panels in Figure 4 , Figures 6 to 9 .

[0067] Taking the display panel in Figure 9 as an example, in combination with Figure 9 and Figure 10 , the display panel driving method in the embodiments of the present application can include the following steps: S1, in the process of driving the display panel, the charging time length of the red sub-pixel is controlled to be greater than the charging time length of the green sub-pixel and the charging time length of the blue sub-pixel, respectively.

[0068] In actual application, since the area (size) of the red sub-pixel 11 in Figures 6 to 9 is the largest, if the charging time of each color sub-pixel is controlled to be the same, for example, the charging time (i.e., the gate line opening time) of the red sub-pixel 11 is controlled to be the same as that of the green sub-pixel 12 and the blue sub-pixel 13, the red sub-pixel 11 with a larger area is prone to the problem of insufficient charging.

[0069] It should be noted that each color sub-pixel in Figure 2 is designed according to the 1G1D architecture, and the red sub-pixel 11 is still driven according to the 1G1D architecture in the embodiments of the present application, as shown in Figure 9 , the red sub-pixel 11 is driven by the gate lines G1 / G2 / G3 / G4 / G5 / G6 / …… and the data lines D1 / D2 / D3 / D4 / ……, at the same time, the green sub-pixel 12 and the blue sub-pixel 13 are driven according to the DLS architecture, i.e., driven and controlled by the gate lines G1 / G2 / G3 / G4 / G5 / G6, etc. and the data lines D1 / D2 / D3 / D4, etc., the same column of green sub-pixels 12 and blue sub-pixels 13 share the same data line, and the specific timing control is as follows:Figure 10 As shown in FIG. 1, the display panel 100 is a 3840x2160 resolution display panel, and the display panel 100 is driven at 120HZ. Therefore, the time for each row to be turned on is 1 / 120 / 2160=3.8μs.

[0070] Based on the above, Figure 9 The display panel can refer to Figure 10 As shown in FIG. 2, in the process of driving the display panel, the red sub-pixel 11 is controlled to be charged twice, and the green sub-pixel 12 and the blue sub-pixel 13 are each controlled to be charged only once, so that the charging time of the red sub-pixel 11 is extended compared with the charging time of the green sub-pixel 12 and the blue sub-pixel 13. Specifically, as shown in FIG. 3, the upper and lower two rows of the red sub-pixel 11 can control the red sub-pixel 11 to be charged in time, and the total charging time of each row of the red sub-pixel 11 can be 3.8x2=7.6μs, so as to improve the problem of insufficient charging of the red sub-pixel 11 due to large size. Figure 9

[0071] At the same time, since the green sub-pixel 12 and the blue sub-pixel 13 use the same data line to control driving, for a display panel with a resolution of 3840x2160, originally 3840x3=11520 data lines are required, and through the display panel of the embodiment of the present application Figure 9 in combination with the driving method of Figure 10 , the number of data lines can be reduced to 3840x2=7680. Therefore, the number of data lines is reduced by 1 / 3, and the number of chip-on-film can be reduced by 1 / 3, thereby reducing the cost of the display panel.

[0072] The driving method of the display panel provided in the embodiment of the present application can control the charging time of the red sub-pixel to be greater than the charging time of the green sub-pixel and the charging time of the blue sub-pixel in the process of driving the display panel, so as to improve the charging efficiency of the large-size red sub-pixel, make the liquid crystal capacitor corresponding to the red sub-pixel reach the target voltage as much as possible, and make the liquid crystal molecules be able to deflect by a sufficient angle, so as to ensure the balance of the brightness of the three primary colors, stabilize the display panel display picture, and have good performance.

The rest is similar, which will not be repeated here.

[0076] It should be noted that, Figure 7 Compared with Figure 6 , the difference is only that the positions of the green sub-pixel 12 and the blue sub-pixel 13 arranged along the length direction (oy direction) of the red sub-pixel 11 are different. Thus, by exchanging the green sub-pixel 12 and the blue sub-pixel 13 in Figure 6 , the connection of each sub-pixel with the gate line and the data line, and the driving sequence of Figure 7 will not be repeated here.

[0082] The display device provided in the embodiments of the present application can include the backlight module and the display panel or the display panel driven by the display panel driving method.

[0083] Further, the backlight module is arranged on the backlight side of the display panel, and the backlight module is configured to provide a color light source for the display panel.

[0084] In actual application, the backlight module can include red chips, green chips, blue chips and the like to realize the color light source. Of course, the color of the color light source in the backlight module is not limited to red, green and blue, but can be any other color, which is subject to actual application.

[0086] The display device provided in the embodiments of the present application has the areas of the red sub-pixel, the green sub-pixel and the blue sub-pixel in each pixel unit decreasing in turn, so that the light transmittance of the light passing through the pixel unit can be improved due to the largest area ratio of the red sub-pixel in the pixel unit. Therefore, even if the red light chip in the backlight module for emitting color light has serious thermal decay, the display device can still have high peak brightness, so that the final display quality of the display device has higher matching degree of the number of emitted light sub-pixels, and better coordination and matching of light can be brought. Meanwhile, the human eye is most sensitive to green, so that the color reproduction degree, brightness perception and power consumption efficiency of the display device can be optimized by setting the area ratio of the green sub-pixel in the pixel unit to be less than that of the red sub-pixel and greater than that of the blue sub-pixel, and the performance of the display device is better.
