Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
In the prior art, since the damage of blue light to vision is extremely large, the eye-protection display mode in the existing display panel mostly adopts the driving voltage (the driving voltage is greater than 0) of the pixel unit with the blue light emission color to achieve the purpose of removing blue light, but the method can cause the problem of image smear of the display panel.
Taking an IPS liquid crystal display panel as an example for illustration, fig. 1 is a schematic structural diagram of a conventional display panel. Referring to fig. 1, the display panel includes a first substrate 01, a second substrate 02, and a liquid crystal layer 03 interposed between the first substrate 01 and the second substrate 02. A pixel electrode 011 and a common electrode 012 are formed on the first substrate 01. In image display, different voltages are applied to the pixel electrode 011 and the common electrode 012, respectively, an electric field is formed between the pixel electrode 011 and the common electrode 012, and the inversion of liquid crystal in the electric field is controlled. In the IPS liquid crystal display panel, the time interval from 0% to 90% of brightness is taken as the on-state response time t on The size of which may characterize the response time of the display panel. On-state response time t on The following relationship is satisfied:
V＝EL。
wherein, gamma 1 For rotational viscosity of liquid crystal, ε 0 Delta epsilon is the dielectric anisotropy constant of the liquid crystal, E is the electric field strength of the electric field formed between the pixel electrode 011 and the common electrode 012, K 22 The elastic modulus of IPS, d is the cell thickness of the IPS liquid crystal display panel, V is the applied voltage between the adjacently disposed pixel electrode 011 and common electrode 012, and L is the distance between the adjacently disposed pixel electrode 011 and common electrode 012. As can be seen from the above formulas, the corresponding liquid crystal display panel is determined due to gamma 1 、ε 0 、Δε、K 22 D and L are all constant values, and the on-state response time t on Only with respect to the applied voltage V. The smaller the applied voltage V, the smaller the electric field strength E of the electric field formed between the pixel electrode 011 and the common electrode 012, the on-state response time t on The larger the display panel response time is, the longer is. When the response time of the display panel exceeds the picture switching time, the phenomenon of smear is seen when the page is dragged.
It should be emphasized that, in the actual setting, the conclusion that "the smaller the applied voltage, the longer the response time of the display panel, and the more likely to cause the smear phenomenon" is true for the TN liquid crystal display panel or the display panel of other structures.
In view of the above, the embodiment of the invention provides a display panel. The display panel includes: a substrate base; forming a plurality of pixel units which are arranged on a substrate in an array structure, wherein the luminous colors of the pixel units comprise blue and red; the display panel comprises a normal display mode and an eye-protection display mode; for the same frame of display picture, the driving voltage of each pixel unit with red luminous color in the eye-protection display mode is equal to the corresponding driving voltage in the normal display mode; for the same frame of display picture, the driving voltage is not equal to 0 in the normal display mode, and the pixel units with the luminous color blue comprise a first type pixel unit and a second type pixel unit, wherein the driving voltage of the first type pixel unit in the eye-protection display mode is equal to 0; the driving voltage of the second type pixel unit in the eye-protection display mode is larger than or equal to the corresponding driving voltage in the normal display mode.
The display panel provided by the embodiment of the invention has the advantages that for the same frame of display picture, the driving voltage is not equal to 0 in the normal display mode, and the pixel units with blue luminous color comprise a first type of pixel units and a second type of pixel units, and the driving voltage of the first type of pixel units in the eye-protection display mode is equal to 0; the driving voltage of the second type pixel unit in the eye-protection display mode is greater than or equal to the driving voltage corresponding to the second type pixel unit in the normal display mode, so that the driving voltage of the first type pixel unit in the eye-protection display mode is equal to 0, which is equivalent to the closing of the first type pixel unit, light cannot exit through liquid crystal molecules corresponding to the first type pixel unit, and the aim of removing blue light can be achieved. In addition, the driving voltage of the first type pixel unit in the eye-protection display mode is equal to 0, and the first type pixel unit does not participate in the display of the frame image, so that the problem of image smear can be solved, and the display effect of the display panel is further improved.
Further, since the sensitivity of human eyes to red light is low, in the above technical scheme, by setting that the driving voltage of each pixel unit with red light emission color in the eye-protection display mode is equal to the corresponding driving voltage in the normal display mode for the same frame of display picture, the eyesight of human eyes is not affected, and the resolution in the display panel is greatly reduced, so that the bad phenomenon of dark spots visible to naked eyes occurs when the display panel displays images can be avoided. In addition, the overall brightness of the display panel in the eye protection mode can be improved, on one hand, the power consumption of the backlight module matched with the display panel is reduced, namely, the fact that the backlight brightness is not required to be lightened is that the image is excessively dark in the eye protection mode is avoided, and the backlight power consumption is increased; on the other hand, the color of the picture is softer, so that the preference of the user is met.
Considering that if any two or more pixel units in close proximity are all the first type of pixel units, in the eye-protection display mode, the driving voltage of each first type of pixel unit needs to be adjusted to be 0, which is easy to cause dark fringes in the display panel. And the lower the resolution of the display panel, the more obvious the dark lines in the display panel, and the poorer the display effect. Therefore, on the basis of the above technical solution, optionally, in the eye-protection display mode, any two immediately adjacent pixel units are not the first type pixel units at the same time in the row direction and/or the column direction of the array structure, so as to reduce the probability of occurrence of dark fringes on the display panel.
Further, for the same frame of display picture, in the eye-protection display mode, the total number of the first type of pixel units and the second type of pixel units is a, and the number of the second type of pixel units is b; b/a is more than or equal to 25% and less than or equal to 100%. The essence of the arrangement is that the adverse phenomenon that partial information included in a display picture cannot be normally presented due to the lack of a pixel unit with a blue luminous color to participate in display is avoided in an eye-protection display mode on the basis of blue light removal.
In actual setting, there are various schemes for realizing that the driving voltage of the first-type pixel unit in the eye-protecting display mode is equal to 0 ". Fig. 2 is a schematic structural diagram of a display panel according to an embodiment of the present invention. Alternatively, referring to fig. 2, the display panel includes a substrate base 10, a plurality of pixel units 11 formed on the substrate base 10 in an array structure, and light emission colors of the plurality of pixel units 11 include blue and red. The display panel further includes a plurality of data lines 12 and a plurality of scan lines 13; the plurality of data lines 12 and the plurality of scanning lines 13 are arranged on the substrate 10 in a crossing manner, and the pixel units 11 are positioned in areas defined by the crossing plurality of data lines 12 and the crossing plurality of scanning lines 13; the pixel unit 11 includes a control switch 111, a pixel electrode 112, and a common electrode 113; the control switch 111 includes a control terminal, a signal input terminal, and a signal output terminal; in each pixel unit 11, a control end of the control switch 111 is connected with a corresponding scanning line 13, a signal input end of the control switch 111 is connected with a corresponding data line 12, and a signal output end of the control switch 111 is connected with a pixel electrode 112; when the drive voltage of any one of the pixel units 11 is equal to the absolute value of the potential difference between the pixel electrode 112 and the common electrode 113 in the pixel unit 11 when the control switch 111 electrically connected to the pixel unit 11 is turned on. Thus, when the driving voltage of the first type pixel unit is required to be equal to 0, the same magnitude voltage signal is inputted to the pixel electrode 112 and the common electrode 113. The arrangement does not need to change the original structure of the liquid crystal display panel, and the liquid crystal display panel is easy to use and realize by only adjusting the electric signal to be input to the common electrode 113.
Further, for the same frame of display picture, in the eye-protection display mode, the driving voltage of the second type of pixel unit is equal to the driving voltage of the second type of pixel unit in the normal display mode; or, for the same frame of display picture, in the eye-protection display mode, the driving voltage of the second type of pixel unit is equal to the driving voltage of the second type of pixel unit when the white picture is displayed. The purpose of this arrangement is that in the eye-protection display mode, the second type pixel units are matched with the pixel units of other luminous colors, so that image display is realized without smear.
In practical setting, if the driving voltage of the first type pixel unit in the eye-protection display mode is equal to 0, the color of the picture to be displayed may be distorted, and the whole picture is yellow. Optionally, on the basis of the above technical solutions, in the display panel, the light emitting color of the pixel unit further includes green; for the same frame of display picture, the driving voltage is not equal to 0 in the normal display mode, and the pixel units with green luminous color comprise a third type of pixel units and a fourth type of pixel units, wherein the driving voltage of the third type of pixel units in the eye-protection display mode is equal to 0; the driving voltage of the fourth type pixel unit in the eye-protection display mode is larger than or equal to the corresponding driving voltage in the normal display mode. The overall color of the display screen can be adjusted through the setting, so that the preference of a user is met.
Similarly, optionally, in the eye-protection display mode, any two immediately adjacent pixel units in the row direction and/or the column direction of the array structure are not the third type of pixel units at the same time, so as to reduce the probability of dark fringes of the display panel.
For the same frame of display picture, in an eye-protection display mode, the total number of the third type of pixel units and the fourth type of pixel units is c, and the number of the fourth type of pixel units is d; d/c is more than or equal to 33% and less than or equal to 100%, so as to avoid the adverse phenomenon that partial information included in a display picture cannot be normally presented due to lack of a pixel unit with green luminous color to participate in display in an eye-protection display mode.
In actual setting, when the driving voltage of the third type pixel unit is required to be equal to 0, the voltage signals with the same amplitude are input to the pixel electrode and the common electrode corresponding to the third type pixel unit. The arrangement does not need to change the original structure of the liquid crystal display panel, and the display is easy to use and realize by only adjusting the electric signal to be input on the common electrode.
Further, for the same frame of display picture, in the eye-protection display mode, the driving voltage of the fourth type of pixel unit is equal to the driving voltage of the fourth type of pixel unit in the normal display mode; or, for the same frame of display picture, in the eye-protection display mode, the driving voltage of the fourth type pixel unit is equal to that of the fourth type pixel unit when the white picture is displayed. The purpose of this arrangement is to realize image display without smear by the cooperation of the fourth type of pixel units and the pixel units of other light-emitting colors in the eye-protection display mode.
In the eye-protection display mode, the pixel units with blue light emission colors are taken as the first type pixel units and the pixel units with the second type pixel units, and when the eye-protection display mode is actually set, the determination methods are various. For example, the determination is made based on the characteristics of the pixel arrangement. In practice, there are various arrangements of pixel units. For the same pixel cell arrangement scheme, the determination methods of which pixel cells with blue light emission color are used as the first type pixel cells and which are used as the second type pixel cells are also various. Similarly, for the same pixel unit arrangement scheme, in the eye-protection display mode, the determination methods of which of the pixel units with green light emission color are used as the third type of pixel units and which are used as the fourth type of pixel units are multiple.
In order to facilitate understanding, a few typical examples will be described in detail below by taking a display panel including a pixel unit having a blue emission color and a pixel unit having a green emission color as an example, but this should not be construed as limiting the present application. It should be noted that, in fig. 3 to 7, the driving voltage of the pixel unit is equal to 0 in the eye-protection display mode shown by diagonal filling.
Fig. 3 is a schematic structural diagram of another display panel according to an embodiment of the invention. Referring to fig. 3, in the display panel, in the array structure, each pixel unit is sequentially arranged in the order of a pixel unit R having a red emission color, a pixel unit G having a green emission color, a pixel unit B having a blue emission color, and a pixel unit R … … having a red emission color along the row direction; in the same column, the luminous colors of the pixel units are the same; in the eye-protecting display mode, in the nth (illustratively, n=1 in fig. 3), the mth (illustratively, m=1 in fig. 3) pixel unit B whose emission color is blue is the first-type pixel unit 101, and the m+1th pixel unit B whose emission color is blue is the second-type pixel unit 102; the pixel unit G with the M-th light emission color being green is the fourth type pixel unit 202, and the pixel unit G with the m+1th light emission color being green is the third type pixel unit 201; in the eye-protection display mode, in the n+1th row, the pixel unit B with the M-th light emission color being blue is the second type pixel unit 102, and the pixel unit B with the m+1th light emission color being blue is the first type pixel unit 101; the pixel unit G with the M-th light emission color being green is the third type of pixel unit 201, and the pixel unit G with the m+1th light emission color being green is the fourth type of pixel unit 202; wherein N, M is a positive integer. Consider the case where a certain position in a certain display screen is displayed as a straight line extending along the row direction of the array structure, but in the eye-protection display mode, all pixel units with the same light-emitting color appear in the row direction at the position, which causes the straight line to be intermittently observed by human eyes or a jaggy feel, and we call the case as poor display smoothness. According to the technical scheme, on the premise that blue light is removed and the problem of image smear is solved, the situation that all pixel units with the same luminous color are closed along the row direction or the column direction in an eye-protection display mode is avoided, and the display smoothness in the eye-protection display mode can be improved.
Fig. 4 is a schematic structural diagram of another display panel according to an embodiment of the invention. Referring to fig. 4, in the display panel, in the array structure, each pixel unit is sequentially arranged in the order of a pixel unit R having a red emission color, a pixel unit G having a green emission color, a pixel unit B having a blue emission color, and a pixel unit R … … having a red emission color along the row direction; in the same column, the luminous colors of the pixel units are the same; in the eye-protecting display mode, in the nth (illustratively, n=1 in fig. 4), the mth (illustratively, m=1 in fig. 4) pixel unit B whose emission color is blue is the first-type pixel unit 101, and the m+1th pixel unit B whose emission color is blue is the second-type pixel unit 102; the pixel unit G with the M-th light emission color being green is the third type of pixel unit 201, and the pixel unit G with the m+1th light emission color being green is the fourth type of pixel unit 202; in the eye-protection display mode, in the n+1th row, the pixel unit B with the M-th light emission color being blue is the second type pixel unit 102, and the pixel unit B with the m+1th light emission color being blue is the first type pixel unit 101; the pixel unit G with the M-th light emission color being green is the fourth type pixel unit 202, and the pixel unit G with the m+1th light emission color being green is the third type pixel unit 201; wherein N, M is a positive integer. The arrangement can also avoid the situation that all pixel units with the same luminous color are closed along the row direction or the column direction in the eye-protection display mode on the premise of removing blue light and solving the problem of image smear, and can improve the display smoothness in the eye-protection display mode.
With continued reference to fig. 4, in the pixel units that are turned off along the row direction, the pixel units of the same color are not adjacent, that is, a pixel unit with a turned off light emitting color of green is further spaced between the two pixel units with a turned off light emitting color of blue, so that the pixel units of a certain light emitting color in the same row are prevented from being obviously missing, and the local color shift of the picture is avoided.
With continued reference to fig. 4, taking the pixel unit R with the second row of red light emission color from the left as an example, in the eye-protecting display mode, in the nth (illustratively, n=1) row, the pixel unit R1 with the red light emission color is immediately adjacent to the pixel unit G with the green light emission color, which is rendered green. In the n+1th row, the pixel unit R1 having the emission color of red is immediately adjacent to the pixel unit B having the emission color of blue, which is rendered blue. In the n+2 row, the pixel unit R1 with the emission color of red is immediately adjacent to the pixel unit G with the emission color of green, which is rendered green. Therefore, all the pixel units with red luminous color are rendered by other colors, and the pixel units with red luminous color, which are adjacent along the array structure column direction, are rendered by different colors, so that the phenomenon that continuous red lines appear on the display panel to cause abnormal display during image display can be effectively avoided. In addition, in the row direction of the array structure, four non-closed pixel units which are arbitrarily adjacent (refer to non-closed pixel unit intervals) can still form the arrangement of RGB combinations, so that the image information can be ensured to be displayed without omission.
Fig. 5 is a schematic structural diagram of another display panel according to an embodiment of the invention. Referring to fig. 5, in the display panel, in the array structure, each pixel unit is sequentially arranged in the order of a pixel unit R having a red emission color, a pixel unit G having a green emission color, a pixel unit B having a blue emission color, and a pixel unit R … … having a red emission color along the row direction; in the same column, the luminous colors of the pixel units are the same; in the eye-protecting display mode, in an nth (illustratively, n=1 in fig. 5), an mth (illustratively, m=1 in fig. 5) and an mth+1th pixel unit B having a blue emission color are the first type pixel unit 101, and an mth+2nd and an mth+3rd pixel unit B having a blue emission color are the second type pixel unit 102; the pixel unit G whose M-th and m+1th emission colors are green is the third-type pixel unit 201; the pixel unit G whose m+2th and m+3rd emission colors are green is the fourth type pixel unit 202; in the eye-protection display mode, in the n+1th row, the pixel units B with the m+1th and m+2th light emission colors being blue are the second type pixel units 102, and the pixel units B with the m+2th and m+3th light emission colors being blue are the first type pixel units 101; the pixel unit G whose mth and m+1th emission colors are green is the fourth type pixel unit 202; the pixel unit G whose m+2th and m+3rd emission colors are green is the third-type pixel unit 201; wherein N, M is a positive integer. The arrangement can also avoid the situation that all pixel units with the same luminous color are closed along the row direction or the column direction in the eye-protection display mode on the premise of removing blue light and solving the problem of image smear, and can improve the display smoothness in the eye-protection display mode. In addition, in the row direction of the array structure, six non-closed pixel units which are arbitrarily adjacent (refer to non-closed pixel unit intervals) can form large-area RGB combined arrangement, and the phenomenon of displaying image information without omission can be ensured.
Fig. 6 is a schematic structural diagram of another display panel according to an embodiment of the invention in order to further improve the display of the display panel. The arrangement structure of the pixel unit in fig. 6 is different from that in fig. 3, 4 and 5. Referring to fig. 6, in the display panel, the array structure includes a plurality of first pixel columns P1, a plurality of second pixel columns P2, and a plurality of third pixel columns P3; the plurality of first pixel columns P1, the plurality of second pixel columns P2, and the plurality of third pixel columns P3 are sequentially and circularly arranged along the row direction; the first pixel column P1 includes a plurality of pixel units R having a red emission color and a plurality of pixel units B having a blue emission color, the pixel units R having a red emission color and the pixel units B having a blue emission color being alternately arranged in a column direction; the second pixel column P2 includes a plurality of pixel units R having a red emission color and a plurality of pixel units G having a green emission color, and the pixel units R having a red emission color and the pixel units G having a green emission color are alternately arranged in the column direction; the third pixel column P3 includes a plurality of pixel units B having a blue emission color and a plurality of pixel units G having a green emission color, and the pixel units B having a blue emission color and the pixel units G having a green emission color are alternately arranged in the column direction; along the row direction, pixel units with the same light emission color are not adjacent. The pixel unit arrangement scheme can improve the visual resolution of the display panel, and further improve the display effect of the display panel.
With reference to fig. 6, in the display panel, in the eye-protecting display mode, in the N (illustratively, n=1 in fig. 6) th row and the n+1th row, the M (illustratively, m=1 in fig. 6) th pixel unit B having a blue emission color is the second type pixel unit 102; the pixel unit B with the m+1th light emission color of blue is the first type pixel unit 101, the pixel unit G with the m+1th light emission color of green is the third type pixel unit 201, and the pixel unit G with the m+1th light emission color of green is the fourth type pixel unit 202; in the n+2th and n+3rd rows, the pixel unit B whose M-th emission color is blue is the first-type pixel unit 101; the pixel unit B with the m+1th light emission color being blue is the second type pixel unit 102, the pixel unit G with the m+1th light emission color being green is the fourth type pixel unit 202, and the pixel unit G with the m+1th light emission color being green is the third type pixel unit 201, wherein N, M is a positive integer.

Fig. 7 is a schematic structural diagram of another display panel according to an embodiment of the invention. The arrangement scheme of the pixel units of the display panel provided in fig. 7 is the same as that of the display panel provided in fig. 6, but in the eye-protection display mode, the determination methods of which of the pixel units with blue emission color are the first type pixel units and which are the second type pixel units are different; similarly, the determination methods of which of the pixel units whose emission color is green are the third type pixel units and which are the fourth type pixel units are different. Specifically, referring to fig. 7, in the display panel, in the eye-protecting display mode, in the first pixel column P1, the pixel units B having the emission color blue are all the second type pixel units 102; in the third pixel column P3, the pixel units B having the emission color blue are all the first-type pixel units 11. In the arrangement scheme of the third pixel column P3, the pixel units B with blue light emission color are all the first-type pixel units 101, and the pixel units B with blue light emission color in the third pixel column P3 are all turned off, but in the arrangement scheme of the pixel units, the first pixel column P1 and the third pixel column P3 are closely adjacent, and the first pixel column P1 plays a role in compensating for the third pixel column P3, so that the influence on display smoothness in the eye-protection display mode is small. In addition, since the sensitivity of human eyes to green is between blue and red, the first type pixel unit 101 is surrounded by the pixel unit G with green light emission color, and when the first type pixel unit 101 is turned off, the surrounding pixel units G with green light emission color are not turned off, and green light is emitted. Because the sensitivity of human eyes to green, the brightness of green and other characteristics are between red and blue, the perception range of the human eyes to green is larger than the area of emergent light of the pixel units G which are not closed, and the positions corresponding to the closed first-type pixel units 101 are covered or rendered by the green light emitted from the periphery of the closed first-type pixel units, the pixel units G with green light emission color play a certain transition role, and the human eyes cannot easily recognize that the first-type pixel units 101 are closed, so that the user experience is improved.
Further, with continued reference to fig. 7, in the display panel, alternatively, for the same frame of display screen, in the eye-protecting display mode, the driving voltage of the pixel unit B with the emission color blue in the first pixel column P1 is greater than 4V. The reason for this is that, in the eye-protection display mode, since the pixel units B with blue emission color in the first pixel column P1 are all the second type pixel units 102 (in fig. 7, the pixel units are the second type pixel units 102 in the eye-protection display mode in a dot matrix filling manner), each second type pixel unit 102 is mainly surrounded by the pixel unit R with red emission color, and by setting the driving voltage of the pixel unit B with blue emission color in the first pixel column P1 (i.e., the second type pixel unit 102) to be equal to the driving voltage thereof when displaying the white screen, the problem of the whole red display in the eye-protection display mode can be better solved. In addition, the driving voltage of the pixel unit B with the blue light emission color in the first pixel column P1 is greater than 4V, so that the problem of image smear of the pixel unit B with the blue light emission color in the first pixel column P1 during image display can be avoided.
Preferably, the driving voltage of the pixel unit B having the emission color blue in the first pixel column P1 is equal to the driving voltage thereof when displaying a white screen.
On the basis of the above technical solutions, optionally, in the display panel, the light emitting color of the pixel unit further includes white; for the same frame of display picture, the driving voltage is not equal to 0 in the normal display mode, and the pixel units with white luminous color comprise a fifth type of pixel units and a sixth type of pixel units, wherein the driving voltage of the fifth type of pixel units in the eye-protection display mode is equal to 0; the driving voltage of the sixth type pixel unit in the eye-protection display mode is greater than or equal to the corresponding driving voltage in the normal display mode. The pixel units with white luminous color are added in the display panel, so that the brightness of the display panel is improved, and the power consumption of the backlight module matched with the display panel for image display is reduced. In addition, since white light is formed by mixing blue light and other color light, blue light emitted from the fifth type pixel unit can be removed by setting the driving voltage of the fifth type pixel unit in the eye-shielding display mode to be equal to 0.
In actual setting, when it is necessary to make the driving voltage of the fifth-type pixel unit equal to 0, optionally, voltage signals of the same magnitude are input to the pixel electrode and the common electrode corresponding to the fifth-type pixel unit. The arrangement does not need to change the original structure of the liquid crystal display panel, and the display is easy to use and realize by only adjusting the electric signal to be input on the common electrode.
Similarly, in the eye-protection display mode, among the pixel units with white light emission color, which are the fifth type pixel units and which are the sixth type pixel units, there are various determination methods in actual design. For example, the determination is made based on the characteristics of the pixel arrangement. The following is a detailed description of typical examples, but is not limiting of the application.
Fig. 8 is a schematic structural diagram of another display panel according to an embodiment of the invention. Referring to fig. 8, in the display panel, in the array structure, in the row direction, pixel units in each row are sequentially arranged in the order of pixel unit R having a red emission color, pixel unit G having a green emission color, pixel unit B having a blue emission color, pixel unit W having a white emission color, and pixel unit R … … having a red emission color; in the same column, the luminous colors of the pixel units are the same; in the eye-protecting display mode, in the nth (illustratively, n=1 in fig. 8), the mth (illustratively, m=1 in fig. 8) pixel unit B whose emission color is blue is the second-type pixel unit 102, and the m+1th pixel unit B whose emission color is blue is the first-type pixel unit 101; the pixel unit G with the M-th light emission color being green is the third type of pixel unit 201, and the pixel unit G with the m+1th light emission color being green is the fourth type of pixel unit 202; the pixel unit W with the mth light-emitting color being white is the sixth type of pixel unit 302, and the pixel unit W with the mth+1th light-emitting color being white is the fifth type of pixel unit 301; in the eye-protection display mode, in the n+1th row, the pixel unit B with the M-th light-emitting color being blue is the first-type pixel unit 101, and the pixel unit B with the m+1th light-emitting color being blue is the second-type pixel unit 102; the pixel unit G with the M-th light emission color being green is the fourth type pixel unit 202, and the pixel unit G with the m+1th light emission color being green is the third type pixel unit 201; the pixel unit W with the mth light-emitting color being white is the fifth type of pixel unit 301, and the pixel unit W with the mth+1th light-emitting color being white is the sixth type of pixel unit 302; wherein N, M is a positive integer. The arrangement can also avoid the situation that all pixel units with the same luminous color are closed along the row direction or the column direction in the eye-protection display mode on the premise of removing blue light and solving the problem of image smear, and can improve the display smoothness in the eye-protection display mode. In addition, the arrangement can avoid the bad phenomenon that the picture is too red and influences the user experience.
Fig. 9 is a schematic structural diagram of another display panel according to an embodiment of the invention. Referring to fig. 9, in the display panel, an array structure includes a plurality of first pixel columns Q1 and a plurality of second pixel columns Q2; the plurality of first pixel columns Q1 and the plurality of second pixel columns Q2 are sequentially and circularly arranged along the row direction; the first pixel column Q1 includes a plurality of pixel units R having a red emission color and a plurality of pixel units B having a blue emission color, the pixel units R having a red emission color and the pixel units B having a blue emission color being alternately arranged in a column direction; the second pixel column Q2 includes a plurality of pixel units W having a white emission color and a plurality of pixel units G having a green emission color, the pixel units W having a white emission color and the pixel units G having a green emission color being alternately arranged in the column direction; in any row, the emission colors of the immediately adjacent four pixel units are different.
With continued reference to fig. 9, alternatively, in the eye-shielding display mode, in the nth (illustratively, n=1 in fig. 9) and n+3rd rows, the mth (illustratively, m=1 in fig. 9) pixel unit B whose emission color is blue is the second-type pixel unit 102, and the m+1th pixel unit B whose emission color is blue is the first-type pixel unit 101; the pixel unit G with the M-th light emission color being green is the third type of pixel unit 201, and the pixel unit G with the m+1th light emission color being green is the fourth type of pixel unit 202; the pixel unit W with the mth light-emitting color being white is the sixth type of pixel unit 302, and the pixel unit W with the mth+1th light-emitting color being white is the fifth type of pixel unit 301; in the n+1th row and the n+2th row, the pixel unit B whose M-th emission color is blue is the first type pixel unit 101, and the pixel unit B whose m+1th emission color is blue is the second type pixel unit 102; the pixel unit G with the M-th light emission color being green is the fourth type pixel unit 202, and the pixel unit G with the m+1th light emission color being green is the third type pixel unit 201; the pixel unit W with the mth light-emitting color being white is the fifth type of pixel unit 301, and the pixel unit W with the mth+1th light-emitting color being white is the sixth type of pixel unit 302; wherein N, M is a positive integer. The arrangement can also avoid the situation that all pixel units with the same luminous color are closed along the row direction or the column direction in the eye-protection display mode on the premise of removing blue light and solving the problem of image smear, and can improve the display smoothness in the eye-protection display mode.
In the actual setting, in the eye-protection display mode, which pixel units with blue light emission color are used as the first type pixel units and which pixel units are used as the second type pixel units can be determined according to the characteristics of the pixel arrangement structure, and also can be determined according to the driving voltage corresponding to the pixel units with blue light emission color in the normal display mode. For the same frame of display screen, in the normal display mode, the driving voltage is not equal to 0, and in the pixel units with blue light emission color, if the driving voltage corresponding to the pixel unit B with blue light emission color is smaller than the set threshold, in the eye-protection display mode, the pixel unit with blue light emission color is the first type pixel unit, and the pixel units with blue light emission color are the second type pixel units; the set threshold is greater than 0 and less than the driving voltage of the pixel unit when displaying the white picture. The essence of the arrangement is that according to the luminous condition of each pixel unit with blue luminous color of the picture to be displayed in the normal display mode, which pixel units with blue luminous color are used as the first type pixel units and which pixel units are used as the second type pixel units are determined, so that real-time adjustment is realized, and each picture to be displayed has a better display effect in the eye-protection display mode.
Alternatively, it is considered that there is a threshold value of the driving voltage at which the picture smear occurs for any display panel. The set threshold value is equal to the critical value of the driving voltage of the display panel with image smear, so that the problem of the image smear can be effectively solved. Further, due to different manufacturing processes of the display panels, different design schemes may cause slightly different threshold values of driving voltages for image smear of different display panels. In general, studies using statistical principles indicate that the range of the threshold value of the driving voltage that causes the display panel to appear picture smear is 3V or more and 4V or less, and therefore, alternatively, the set threshold value is set to 3V or more and 4V or less to solve the problem of picture smear.
