Title: Display panel

Description:
BACKGROUND OF INVENTION 
     Field of Invention 
     The present application relates to a field of display technology, and particularly relates to a display panel. 
     Description of Prior Art 
     In general display panels, although polarizers (POL) can effectively reduce a reflectivity under a glare where the display panels are, it loses almost 58% of light emission. This causes a great burden for organic light-emitting diode (OLED) panels and shortens their service life. 
     On the other hand, the polarizers have large thickness, brittle property, etc., which is unfavorable for development of dynamic bending products. For developing a dynamic bending product on the basis of OLED display technology, new material, new technology, and new processes need to import to replace the polarizers. 
     In current display panels using polarizers, technical problems of loss light emission and unfavorable for development of dynamic bending products exist.

Therefore, the used directional terms are for illustrating and understanding the present application, but not for limiting the present application. 
     In the figures, units with similar structures are indicated by the same reference numerals. 
     As illustrated in  FIG.  1   , the display panel  10  of the present application has an active display region AA (active area) for displaying images. Furthermore, the display panel  10  can be a screen with a display function, for example, a screen of a mobile phone, a computer, or a wearable device.

     Furthermore, the substrate  100  can be an array substrate and can include elements such as transistors, common electrodes, etc. In one embodiment, when manufacturing display panel  10  of the present application, a flexible substrate can be formed by depositing polyimide (PI) on a substrate, such as a glass substrate. Then, manufacture of the substrate  100 , the pixel definition layer  200 , the light-emitting layer  300 , the encapsulation layer  400  is completed in sequence. After that, the black matrix layer  500  and the color film layer  600  are manufactured. Finally, an adhesive, such as optical clear adhesive (OCA), is coated to form an adhesive layer  800  for subsequent assembly with other module materials. Therefore, the display panel  10  of the present application is a polarizer-less (POL-Less) display panel  10 .

In one embodiment, as illustrated in  FIG.  9   , the light-emitting layer  300  can include a first sub-pixel  310  displaying a first color, a second sub-pixel  320  displaying a second color, and a third sub-pixel  330  displaying a third color, and the first sub-pixel  310 , the second sub-pixel  320 , and the third sub-pixel  330  are disposed in the plurality of first openings  201 . Specifically, the first sub-pixel  310 , the second sub-pixel  320 , and the third sub-pixel  330  can be a red sub-pixel, a green sub-pixel, and a blue sub-pixel respectively.

     In one embodiment, the encapsulation layer  400  can cover the pixel definition layer  200  and the light-emitting layer  300 . In addition, the encapsulation layer  400  can be a thin-film encapsulation (TFE) layer. TFE is a technology that inorganic film layers and organic film layers are stacked on an organic material layer to prevent external pollution. Inorganic film layers can prevent penetration. However, property of the inorganic film layers is uneven, and organic film layers can help stabilize the inorganic film layers. 
     The black matrix layer  500  is disposed between the light-emitting layer  300  and the color film layer  600  and can be disposed on the encapsulation layer  400  corresponding to the light-emitting layer  300  and the pixel definition layer  200 . A plurality of second openings  501  can be defined in the black matrix layer  500 . A color film layer  600  can be filled in the second openings  501 . 
     Furthermore, as illustrated in  FIG.  2    to  FIG.  9   , the color film layer  600  is disposed on a side of the light-emitting layer  300  away from the substrate and includes a first color resist  610  corresponding to the first sub-pixel  310 , a second color resist  620  corresponding to the second sub-pixel  320 , and a third color resist  630  corresponding to the third sub-pixel  330 ; and The first color resist  610 , the second color resist  620 , and the third color resist  630  are disposed in the plurality of second openings  501 . In addition, in one embodiment, the first color resist  610 , the second color resist  620 , and the third color resist  630  can be a red color resist, a green color resist, and a blue color resist respectively. 
     In one embodiment, a first area ratio of the first color resist  610  to the first sub-pixel  310  is greater than a second area ratio of the second color resist  620  to the second sub-pixel  320  and a third area ratio of the third color resist  630  to the third sub-pixel  330 . 
     In one embodiment, the color film layer  600  can be disposed corresponding to a position of the light-emitting layer  300  to correspond light emitted from the light-emitting layer  300  and to prevent interference of ambient light. Furthermore, the black matrix layer  500  can prevent light leakage and has an effect of reducing reflection. 
     Specifically, in one embodiment, as illustrated in  FIG.  2    to  FIG.  9   , an area of the second openings  501  corresponding to the first sub-pixel  310  and an area of the first color resist  310  are greater than an area of the first sub-pixel  310 ; an area of the second openings  501  corresponding to the second sub-pixel  320  and an area of the second color resist  620  are greater than an area of the second sub-pixel  320 ; and an area of the second openings  501  corresponding to the third sub-pixel  330  and an area of the third color resist  630  are greater than an area of the third sub-pixel  330 . 
     Therefore, in the display panel  10  of the present application, the black matrix layer  500  and the color film layer  600  disposed on the encapsulation layer  400  is used to replace polarizers in the prior art to realize effects of reducing a thickness of the display panel  10  and increasing a light emission rate. 
     In one embodiment, the display panel  10  of the present application can also have a touch function. As illustrated in  FIG.  3   ,  FIG.  5   ,  FIG.  7   , and  FIG.  9   , the display panel  10  can further includes a touch structure  700 . The touch structure  700  can be disposed on the encapsulation layer  400 . The black matrix layer  500  and the color film layer  600  can be disposed on the touch structure  700 . The touch structure  700  can include a metal wiring layer  701 . Furthermore, in one embodiment, the touch structure  700  relates to integrated touch technology, i.e., the display panel  10  of the present application can highly integrate display and touch functions. By integrating touch and display technologies into single-chip and dual-chip solutions, the display panel  10  is allowed to be lighter and thinner. 
     In one embodiment, as illustrated in  FIG.  3   ,  FIG.  5   ,  FIG.  7   , and  FIG.  9   , in order to prevent the metal wiring layer  701  from affecting display of the display panel  10 , the metal wiring layer  701  can be disposed corresponding to the black matrix layer  500 , i.e., an orthogonal projection of the black matrix layer  500  completely covers the metal wiring layer  701  in a surface of the substrate  100  where the pixel definition layer  200  is disposed. 
     In one embodiment, as illustrated in  FIG.  3    and  FIG.  4   , on the side of the substrate  100  where the light-emitting layer  300  is disposed, a first lateral edge  6011  of a first orthogonal projection  601  of the color film layer  600  disposed in the second openings  501  completely overlaps with a second orthogonal projection  502  of the black matrix layer  500 . Therefore, the color film layer  600  and the black matrix layer  500  can completely cover corresponding light-emitting layer  300  to correspond to the light emitted from the light-emitting layer  300  and prevent interference of ambient light. 
     In another embodiment, as illustrated in  FIG.  5    and  FIG.  6   , on the side of the substrate  100  where the light-emitting layer  300  is disposed, the first lateral edge  6011  of the first orthogonal projection  601  of the color film layer  600  disposed in the second openings  501  partially overlaps with the second orthogonal projection  502  of the black matrix layer  500 , and a gap between the first lateral edge  6011  of the first orthogonal projection  601  and a second lateral edge  5021  of the second orthogonal projection  502  overlaps with a third orthogonal projection  202  of the pixel definition layer  200 . Therefore, the color film layer  600  and the black matrix layer  500  can completely cover corresponding light-emitting layer  300  to correspond to the light emitted from the light-emitting layer  300  and prevent interference of ambient light. 
     In one further embodiment, as illustrated in  FIG.  7    and  FIG.  8   , on the side of the substrate  100  where the light-emitting layer  300  is disposed, a gap is between the first lateral edge  6011  of the first orthogonal projection  601  of the color film layer  600  disposed in the second openings  501  and the second lateral edge  5021  of the second orthogonal projection  502  of the black matrix layer  500 , and the gap between the first lateral edge  6011  of the first orthogonal projection  601  and the second lateral edge  5021  of the second orthogonal projection  502  overlaps with the third orthogonal projection  202  of the pixel definition layer. Therefore, the color film layer  600  and the black matrix layer  500  can completely cover corresponding light-emitting layer  300  to correspond to the light emitted from the light-emitting layer  300  and prevent interference of ambient light. 
     Furthermore, in one embodiment, as illustrated in  FIG.  9   , the plurality of first openings  201  can include a first sub-opening  2011  corresponding to the first sub-pixel  310 , a second sub-opening  2012  corresponding to the second sub-pixel  320 , and a third sub-opening  2013  corresponding to the third sub-pixel  330 ; the plurality of second openings  501  include a fourth sub-opening  5011  corresponding to the first color resist  610 , a fifth sub-opening  5012  corresponding to the second color resist  620 , a sixth sub-opening  5013  corresponding to the third color resist  630 ; and wherein a fourth area ratio of the fourth sub-opening  5011  to the first sub-opening  2011  is greater than a fifth area ratio of the fifth sub-opening  5012  to the second sub-opening  2012  and a sixth area ratio of the sixth sub-opening  5013  to the third sub-opening  2013 . 
     In one embodiment, colors of lights emitted from the light-emitting layer  300  are same as colors of the color film layer  600 , i.e., the first color is same as the color of the first color resist  610 , the second color is same as the color of the second color resist  620 , and the third color is same as the color of the third color resist  630 . In addition, in one embodiment, the fourth area ratio, the fifth area ratio, and the sixth area ratio range from 1 to 2.5. 
     Specifically, the display panel  10  of  FIG.  9    is taken as an example for description. The structure of  FIG.  9    is similar to the structure of  FIG.  3   . The difference between  FIG.  9    and  FIG.  3    is that the first sub-pixel  310 , the second sub-pixel  320 , the third sub-pixel  330 , the first color resist  610 , the second color resist  620 , and the third color resist  630  are further illustrated in  FIG.  9   . 
     It should be noted that in the embodiments of  FIG.  3    to  FIG.  8   , the light-emitting layer  300  can be regarded as the first sub-pixel  310 , the second sub-pixel  320 , or the third sub-pixel  330 , and the color film layer  600  can be regarded as any one of the first color resist  610 , the second color resist  620 , or the third color resist  630 , but the colors of the lights emitted from the light-emitting layer  300  should be same as the colors of the color film layer  600 . In other words, in the embodiments of  FIG.  3    to  FIG.  8   , if the light-emitting layer  300  is the first sub-pixel  310 , the color filter layer  600  directly above the light-emitting layer  300  is the first color resist  610 . 
     Therefore, as illustrated in  FIG.  9   , right above the first sub-pixel  310  is the first color resist  610 , right above the second sub-pixel  320  is the second color resist  620 , and right above the third sub-pixel  330  is the third color resist  630 . 
     In one embodiment, when the color film layer  600  is the first color resist  610 , i.e., when the first color is red, the fourth area ratio of the fourth sub-opening  5011  to the first sub-opening  2011  ranges from 1.35 to 1.4, and chamfers are configured in the fourth sub-opening  5011  and the first sub-opening  2011  to make the display panel  10  of the present application have a better display effect. 
     In one embodiment, when the color film layer  600  is the second color resist  620 , i.e., when the second color is green the fifth area ratio of the fifth sub-opening  5012  to the second sub-opening  2012  ranges from 0.9 to 1.1, and the fifth sub-opening  5012  and the second sub-opening  2012  are elliptical to make the display panel  10  of the present application have a better display effect.

     In table 2, the power consumption represents the power consumption of lighting a screen of the display panel  10 . Here, the power consumption of the light-emitting layer  300  does not include power consumption of driving circuits such as chips. 
     Color gamut refers to a sum of colors under the national television system committee (NTSC) standard, and the larger the value is, the better the display effect is. 
     Uniformity (an actual brightness of sub-pixels under 255 gray scale, L255) refers to uniformity of brightness and chromaticity in different regions of a same screen. White angular dependence (WAD) refers to a color shift situation of the display panel  10 . Table 2 is represented by the “JNCD” index of (30°, 45°,60°), and wherein JNCD is “Just Noticeable Color Difference”, which is a standard for measuring color accuracy of the screen. The smaller the value is, the more accurate the color displayed on the screen is. 
     Luminance-decay (L-Decay) is a brightness viewing angle, which means that the brightness of the screen is attenuated by 50% when deviates from a certain angle, and this angle can range from 30° to 40°. Reflectivity refers to a reflectivity when the screen is turned off, this value should be as small as possible. 
     Hue (Lab) represents the chromaticity of the colors and represents hue when the screen is turned off, wherein “L” represents brightness of colors, “a” represents values from magenta to green, and “b” represents values from yellow to blue. Combined with the reflectivity, Lab should be as small as possible.
