Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.
The embodiment of the application provides a display device and electronic equipment. The electronic device may be a mobile terminal such as a smart phone and a tablet computer, or may be a game device, an Augmented Reality (AR) device, a Virtual Reality (VR) device, a data storage device, an audio playing device, a video playing device, a wearable device, and the like, wherein the wearable device may be a smart band, smart glasses, a smart watch, a smart decoration, and the like.
The display device will be described in detail below.
In the related art, since the liquid crystal display device with RGBW subpixel arrangement adds a white subpixel, and the color resistance position of the white subpixel is a transparent color resistance (such as a transparent film layer), different wavelengths of light cannot be selected, and only the amount of light transmitted can be selected, and the transmitted spectrum depends on the backlight used. The white light emitted by the backlight module is generally compounded by mixing blue light emitted by the blue LED chip with yellow phosphor, and therefore the spectrum of the white light emitted by the backlight module is generally blue. The red sub-pixel R, the green sub-pixel G and the blue sub-pixel B can realize the absorption of blue light by matching the material lines and the thicknesses of the corresponding color resistances, and finally match the white point coordinate of the white picture meeting the requirement. However, the white sub-pixel W cannot selectively transmit the spectrum of the backlight, and the white color point of the white sub-pixel W is different from the white color point mixed by the R, G, B primary color sub-pixels, so that the white point coordinate of the white image of the liquid crystal display device with the RGBW sub-pixel arrangement is shifted, and the display effect is blue.
Therefore, the present embodiment provides a display device, please refer to fig. 1, and fig. 1 is a first structural schematic diagram of the display device according to the embodiment of the present application. The display device includes a first substrate 230, a liquid crystal layer 250, a color resist layer 270, and a second substrate 280. Wherein the first substrate 230 and the second substrate 280 are oppositely disposed. The color resist layer 270 is disposed between the first substrate 230 and the second substrate 280, and the color resist layer 270 includes a color resist 272 and a transparent resist 274. The liquid crystal layer 250 is disposed between the color resist layer 270 and the first substrate 230, the liquid crystal layer 250 includes a first liquid crystal portion 252 and a second liquid crystal portion 254, the first liquid crystal portion 252 is disposed corresponding to the color resist 272, the second liquid crystal portion 254 is disposed corresponding to the transparent color resist 274, the first liquid crystal portion 252 includes a first liquid crystal 2522, and the second liquid crystal portion 254 includes a second liquid crystal 2542.
The color resistor 272 blocks a predetermined light signal transmitted through the first liquid crystal portion 252, and the difference in birefringence of the second liquid crystal 2542 is different from the difference in birefringence of the first liquid crystal 2522, such that the transmittance of the predetermined light signal transmitted through the second liquid crystal portion 254 is less than the transmittance of the predetermined light signal transmitted through the first liquid crystal portion 252.
The display device 200 includes a color sub-pixel (RGB sub-pixel) and a white sub-pixel (W sub-pixel), the color resist layer 270 includes a color resist 272 corresponding to the color sub-pixel and a transparent resist 274 corresponding to the white sub-pixel, the liquid crystal layer 250 also includes a first liquid crystal portion 252 corresponding to the color sub-pixel and a second liquid crystal portion 254 corresponding to the white sub-pixel, wherein the color resist 272 can block a predetermined light signal (e.g., a blue light signal in a backlight emitted by a backlight module) transmitted through the first liquid crystal portion 252, so that a white picture synthesized by the color sub-pixels meets requirements. The transparent color resistor 274 cannot block the predetermined light signal, but the difference of the birefringence of the second liquid crystal 2542 of the second liquid crystal portion 254 is different from the difference of the birefringence of the first liquid crystal 2522 of the first liquid crystal portion 252, i.e. the second liquid crystal selects a suitable liquid crystal material, so that the transmittance of the predetermined light signal through the second liquid crystal portion 254 is less than the transmittance through the first liquid crystal portion 252, and the transmittance of the predetermined light signal through the second liquid crystal portion 254 is reduced by the second liquid crystal 2542, thereby blocking most or all of the predetermined light signals, making the white frame displayed by the white sub-pixel close to or the same as the white point coordinate of the white frame synthesized by the color sub-pixels, making the white frame displayed by the display panel meet the requirements as a whole, and avoiding the problems of bluish and the like.
To facilitate understanding of the display device of the embodiments of the present application. The following describes a laminated structure of the display device. Referring to fig. 2, fig. 2 is a second structural schematic diagram of a display device according to an embodiment of the present disclosure.
The display device 200 includes a backlight module 210, a lower polarizer 220, a first substrate 230, a display array layer 240, a liquid crystal layer 250, a planarization layer 260, a color resist layer 270, a second substrate 280, an upper polarizer 290, and the like.
The backlight module 210 provides backlight, the liquid crystal layer 250 is used to control the transmission amount of the backlight, the lower polarizer 220 and the upper polarizer 290 are used to control the light path of the backlight in cooperation, and the color resist layer 270 can change the transmitted monochromatic backlight (white light) into light of a desired color, such as red light, green light, blue light, white light, and the like, and combine the light into light signals of various colors, thereby displaying different images. The planarization layer 260 is used to fill in some of the grooves in the color resist layer, and the display array layer 240 includes driving circuits for controlling each of the sub-pixels, which can also be understood as controlling the area of the liquid crystal layer 250 corresponding to each of the color resists.
The essential of liquid crystal optics is to control the transmission of light by using the birefringence of liquid crystal, and the first equation of the transmittance calculation equivalent is:
T＝T0sin22Φsin2(πdΔn/λ)；
wherein, T0The transmittance of the display device itself is Φ is an included angle between an optical axis of the liquid crystal and a transmission optical axis of the polarizer, Δ n is a difference in birefringence of the liquid crystal (Δ n is ne-no, ne is a refractive index in a long axis direction of the liquid crystal, no is a refractive index in a short axis direction of the liquid crystal, as shown in fig. 3), d is a thickness (cell gap) of the liquid crystal layer 250, and λ is a wavelength of light passing through the liquid crystal.
The white dot coordinate in the display device 200 refers to a white dot coordinate when the display device 200 displays a white picture, where Φ is 45 °, the display device 200 has the maximum luminance, and the above equivalent formula one becomes the equivalent formula two:
T＝T0sin2(πdΔn/λ)；
the color resistors 272 include a red resistor, a blue resistor, and a green resistor, the red resistor is used for passing red light and filtering out light of other colors, the blue resistor is used for passing blue light and filtering out light of other colors, the green resistor is used for passing green light and filtering out light of other colors, so as to obtain light signals of three primary colors (red light, green light, and blue light), and the light signals are combined to form various light signals of various required colors. The first liquid crystals 2522 corresponding to the color resists 272 are the same, and the colors of the light signals passing through the color resists of different colors are different, i.e., the wavelengths of the light waves passing through the color resists of different colors are different, so that the first liquid crystals 2522 need to satisfy the requirements of the color resists of three colors, and therefore, the corresponding relationship between the first liquid crystal portions 252 and the wavelengths of the transmitted light is shown in fig. 4. It should be noted that, the color sub-pixels select the optical signal with the specific light wave wavelength to filter out the preset optical signals of other colors doped in the backlight, when the color sub-pixels are synthesized to display the white picture, the white picture does not carry the preset optical signals of other colors, the coordinate points of the white picture meet the requirements, and the displayed white picture has good effect and does not deviate color.
The transparent color resist 274 is a transparent material and cannot select different wavelengths of light. The transmittance of the display device 200 is a sine function related to λ, and when Δ nd is λ/2, the display device 200 has the highest transmittance, that is, light with a desired wavelength can be more easily transmitted by adjusting Δ nd, so as to control the color point of the white subpixel W. Specifically, when the light signal of the other color doped in the backlight transmits through the second liquid crystal 2542, the birefringence difference Δ n of the second liquid crystal 2542 is adjusted to decrease the transmittance of the preset light signal of the other color doped in the backlight. For example, Δ nd is equal to the wavelength of the preset optical signal, so that the preset optical signal is completely opaque, which is equivalent to filtering the preset optical signal by the white sub-pixel, the coordinate point of the white picture displayed by the white sub-pixel meets the requirement, and the displayed white picture has good effect and no color cast. For example, the backlight is blue, that is, the blue-doped default light signal in the backlight is adjusted to decrease the birefringence Δ n of the blue default light signal, so that the white picture displayed by the white sub-pixel is not blue, and the white point coordinate of the white picture displayed by the transparent color resist 274 is the same as the white point coordinate of the white picture displayed by the color resist 272. The white point coordinates may be understood as the color coordinate points when the display device displays a white picture.
It can be seen from the above formula that the light transmittance of the preset light signal can be reduced not only by adjusting the difference in birefringence of the second liquid crystal, but also by adjusting the thickness of the second liquid crystal portion. Referring to fig. 5, fig. 5 is a schematic view illustrating a third structure of a display device according to an embodiment of the present disclosure. The difference in birefringence of the second liquid crystal 2542 is different from the difference in birefringence of the first liquid crystal 2522, and the thickness of the second liquid crystal 254 is different from the thickness of the first liquid crystal 252, so that the white point coordinate of the white picture displayed through the color resistor 272 is the same as the white point coordinate of the white picture displayed through the transparent color resistor 274. If only the difference Δ n in birefringence of the second liquid crystal 2542 is adjusted, the transmittance of the blue predetermined light signal may not be sufficient or may be difficult to achieve. In this case, a better effect can be achieved by adjusting the thickness of the second liquid crystal section 254. For example, the backlight is blue, i.e., a blue-doped default light signal in the backlight, the birefringence difference Δ n of the second liquid crystal 2542 is adjusted, and the thickness of the second liquid crystal portion 254 is adjusted so that Δ nd is equal to the wavelength of the default light signal, thereby completely preventing the default light signal from transmitting, preventing the white picture displayed by the white sub-pixel from being blue, and making the white point coordinate of the white picture displayed by the transparent color resist 274 and the white point coordinate of the white picture displayed by the color resist 272 the same.
The thickness of the second liquid crystal section 254 can be adjusted by adjusting the structures of both sides of the second liquid crystal section 254. Specifically, the display device 200 further includes a planarization layer 260, the planarization layer 260 is disposed between the color resist layer 270 and the liquid crystal layer 250, and the planarization layer 260 includes a first surface 262 adjacent to the first liquid crystal portion 252 and a second surface adjacent to the second liquid crystal portion 254, the second surface being higher or lower than the first surface 262, so that the thickness of the first liquid crystal portion 252 is different from the thickness of the second liquid crystal portion 254. The planarization layer 260 adjacent to the second liquid crystal section 254 is adjusted as necessary. Illustratively, the planarization layer 260 includes a first planarization portion adjacent to the first liquid crystal portion 252 and including a first surface 262 adjacent to the first liquid crystal portion 252, and a second planarization portion corresponding to the second liquid crystal portion 254 and including a second surface adjacent to the second liquid crystal portion 254, and the thickness of the second planarization portion is adjusted such that the second surface is higher or lower than the first surface 262.
In addition, the thickness of the transparent color resist 274 can be adjusted because the transparent color resist does not need to be selective for light signals with specific wavelengths like the color resist 272, the thickness of the transparent color resist 274 can be adjusted to make the thickness of the transparent color resist 274 different from that of the color resist 272, and the planarization layer 260 is combined to make the first liquid crystal portion 252 different from that of the second liquid crystal portion 254. The thickness of the transparent color resist may even be adjusted to 0, that is, the transparent color resist 274 is completely removed, and the corresponding position is filled with the planarization layer 260.
It should be noted that, because the backlight sources of the backlight module 210 are different, the difference of the birefringence of the adjusted second liquid crystal 2542 may be larger than or smaller than that of the first liquid crystal 2522, and similarly, the thickness of the adjusted second liquid crystal portion 254 may be larger than or smaller than that of the first liquid crystal portion 252. For example, if the backlight is blue, the difference of the birefringence of the adjusted second liquid crystal 2542 is greater than that of the first liquid crystal 2522, and the thickness of the adjusted second liquid crystal 254 is greater than that of the first liquid crystal 252.
Referring to fig. 2 or fig. 5, the first liquid crystal 2522 and the second liquid crystal 2542 in the liquid crystal layer 250 are both in liquid state, and cannot support the structures on both sides of the liquid crystal layer 250 well, so that the liquid crystal layer 250 is supported by the support pillars 256. The supporting column 256 may be disposed between the first liquid crystal portion 252 and the second liquid crystal portion 254, and the first liquid crystal portion 252 and the second liquid crystal portion 254 are disposed at an interval, and by multiplexing the supporting column 256, not only the liquid crystal layer 250 may be supported, but also the first liquid crystal portion 252 and the second liquid crystal portion 254 may be separated, and there is no need to additionally provide another structure. A continuous supporting column 256 may be provided between the first liquid crystal section 252 and the second liquid crystal section 254 to separate the first liquid crystal 2522 of the first liquid crystal section 252 and the second liquid crystal 2542 of the second liquid crystal section 254. It should be noted that the first liquid crystal section 252 corresponds to a plurality of color sub-pixels (RGB), the second liquid crystal section 254 corresponds to one white sub-pixel (W), and the area of the first liquid crystal section 252 is larger than that of the second liquid crystal section 254, so that some supporting columns 256 may be provided in the first liquid crystal section 252, and the supporting columns 256 in the first liquid crystal section 252 may be provided at intervals. The size of the supporting pillars 256 in the first liquid crystal portion 252 can be matched with the size of the first liquid crystals 2522, the supporting pillars 256 in the first liquid crystal portion 252 cannot space the first liquid crystals 2522, and the first liquid crystals 2522 in the first liquid crystal portion 252 cannot be spaced by the supporting pillars 256.
Referring to fig. 6, fig. 6 is a schematic view illustrating a fourth structure of a display device according to an embodiment of the present disclosure. The liquid crystal layer includes a plurality of the first liquid crystal sections 252 and a plurality of the second liquid crystal sections 254, the plurality of the first liquid crystal sections 252 and the plurality of the second liquid crystal sections 254 are disposed along a first direction, the plurality of the first liquid crystal sections 252 communicate through a first connection passage 2524, the plurality of the second liquid crystal sections 254 communicate through a second connection passage 2544, the first connection passage 2524 and the second connection passage are disposed along a second direction, and the first direction and the second direction are perpendicular to each other.
The color sub-pixels and the white sub-pixels need to be uniformly arranged, and therefore, the corresponding first liquid crystal portions 252 and the corresponding second liquid crystal portions 254 need to be uniformly arranged, when the color sub-pixels and the white sub-pixels are arranged in a first direction (such as a column direction), the corresponding first liquid crystal portions 252 and the corresponding second liquid crystal portions 254 are also arranged in the first direction (such as the column direction), and when the first liquid crystal and the second liquid crystal need to be poured into the liquid crystal layers, the liquid crystal can be poured into the openings of the first liquid crystal portions 252 and the second liquid crystal portions 254, and then the liquid crystal portions are respectively sealed. The first liquid crystal portions 252 may be communicated with each other through the first connection passage 2524, the second liquid crystal portions 254 may be communicated with each other through the second connection passage 2544, the first liquid crystal 2522 may be filled through one opening, and the second liquid crystal may be filled through one opening, so that the number of openings of the liquid crystal layer may be reduced, and the operation process may be optimized. Wherein the first connecting channel 2524 and the second connecting channel are arranged in a second direction (e.g., a row direction). The first direction and the second direction are perpendicular.
The first connection channel 2524 and the second connection channel are located at two opposite ends of the liquid crystal layer 250, and the first liquid crystal portion 252 and the second liquid crystal portion 254 may be alternately disposed and respectively communicated through the connection channels at the two ends, so as to optimize the layout of the first liquid crystal portion 252 and the second liquid crystal portion 254.
The color resistors 272 and 274 and the color resistors 272 can be separated by a black matrix 276 to prevent color crosstalk between pixels.
In some other embodiments, the display device may not be provided with the first connecting channel and the second connecting channel, the plurality of first liquid crystal portions and the plurality of second liquid crystal portions are independently provided, and liquid crystal is poured into the liquid crystal portions for a plurality of times to obtain the independent plurality of first liquid crystal portions and the independent plurality of second liquid crystal portions.
Fig. 7 is a schematic view of a fifth structure of the display device according to the embodiment of the present disclosure, and fig. 7 is a schematic view of the display device according to the embodiment of the present disclosure. The main differences from the display device in the above-described embodiment are the color resist layer and the liquid crystal layer. Specifically, the color resistors 272 of the display device 200 of the present embodiment block the predetermined light signal transmitted through the first liquid crystal portion 252, and the first liquid crystal portion 252 is different from the second liquid crystal portion 254 in thickness, so that the transmittance of the predetermined light signal transmitted through the second liquid crystal portion 254 is smaller than the transmittance of the predetermined light signal transmitted through the first liquid crystal portion 252. The first liquid crystal 2522 of the first liquid crystal portion 252 and the second liquid crystal 2542 of the second liquid crystal portion 254 may be the same liquid crystal, and the transmittance of the preset optical signal transmitted through the second liquid crystal portion 254 is adjusted to be smaller than the transmittance of the preset optical signal transmitted through the first liquid crystal portion 252 by adjusting the thickness of the second liquid crystal portion 254. According to equation two of the above embodiment:
T＝T0sin2(πdΔn/λ)；
if the first liquid crystal 2522 and the second liquid crystal 2542 are the same, the transmittance of the predetermined optical signal through the second liquid crystal portion 254 can be reduced by adjusting the thickness of the liquid crystal layer 250.
The display device 200 also includes a planarization layer 260, the planarization layer 260 abutting the liquid crystal layer 250, the planarization layer 260 including a first planarization part 262 corresponding to the first liquid crystal part 252, and a second planarization part 264 corresponding to the second liquid crystal part 254, the second planarization part 264 forming the transparent color resist 274, the first planarization part 262 including a first surface abutting the first liquid crystal part 252, the second planarization part 264 including a second surface abutting the second liquid crystal part 254, the second surface being higher or lower than the first surface so that the thickness of the first liquid crystal part 252 is different from the thickness of the second liquid crystal part 254.
It should be noted that, in some other embodiments, as shown in fig. 8, the color-resist layer 270 may further include a transparent color resist 274, and the transmittance of the predetermined optical signal through the second liquid crystal portion 254 is reduced by adjusting the thickness of the transparent color resist 274 and adjusting the thickness of the second liquid crystal portion 254 by cooperating with the planarization layer 260.
Because the adjustment range is limited if only the thickness of the second liquid crystal portion is adjusted, the adjustment range may not be satisfactory. At this time, the parameters of the liquid crystal can be adjusted to assist the adjustment, so that the adjustment can meet the requirements. Specifically, the first liquid crystal portion includes a first liquid crystal, the second liquid crystal portion includes a second liquid crystal, a birefringence difference of the second liquid crystal is different from a birefringence difference of the first liquid crystal, and a thickness of the second liquid crystal portion is different from a thickness of the first liquid crystal portion, so that a white point coordinate of a white picture displayed through the transparent color resist is the same as a white point coordinate of a white picture displayed through the color resist, as shown in fig. 9. For details, reference may be made to the above embodiments, which are not described herein again.
In the display device of any of the above embodiments, the color sub-pixel and the white sub-pixel may be arranged in an RGBW manner, as shown in fig. 10. For better arrangement of the second liquid crystal section, the sub-pixels may also be arranged in other ways, such as rgbwrgb, as shown in fig. 11. The display device may also be arranged in rgbwbgr mode as shown in fig. 12. The composite display of the color sub-pixels (RGB) and the white sub-pixels (W) is not influenced, the second liquid crystal parts can be gathered, and the process difficulty is reduced by optimizing the pixel arrangement mode.
