The display device will be described in detail below.

In the related art, since the liquid crystal display device with the RGBW sub-pixel arrangement adds white sub-pixels, the color resistance of the white sub-pixels is a transparent color resistance (such as a transparent film layer), and it is not possible to select different wavelengths of light, but can only choose light-transmitting. The amount of light and the transmitted spectrum depend on the backlight used. The white light emitted by the backlight module is usually combined with the blue light emitted by the blue LED chip and mixed with yellow phosphor. Therefore, the white light spectrum emitted by the backlight module is usually blue. The red sub-pixel R, the green sub-pixel G, and the blue sub-pixel B can absorb blue light by matching the material row and thickness of their corresponding color resists, and finally match the white point coordinates of the white screen that meets the requirements. Since the white sub-pixel W cannot selectively pass through the spectrum of the backlight, the white color point of the white sub-pixel W is different from the white color point formed by the three primary color sub-pixels of R, G, and B, resulting in the liquid crystal of the RGBW sub-pixel arrangement. The white point coordinates of the white screen of the display device are offset, causing the display effect to be blue.

Therefore, this embodiment provides a display device. Please refer to FIG. 1. FIG. 1 is a schematic diagram of the first structure of the display device provided by an embodiment of the 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 arranged opposite to each other. 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 color 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 corresponds to the color The color resist 272 is provided, the second liquid crystal portion 254 is provided 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 resistance 272 blocks the predetermined light signal passing through the first liquid crystal portion 252, and the birefringence difference of the second liquid crystal 2542 is different from the birefringence difference of the first liquid crystal 2522, so as to The transmittance of the predetermined light signal through the second liquid crystal portion 254 is lower than the transmittance of the first liquid crystal portion 252.

The display device 200 includes color sub-pixels (RGB sub-pixels) and white sub-pixels (W sub-pixels). The color resist layer 270 includes a color resist 272 corresponding to the color sub-pixel and a transparent color 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-pixels, and a second liquid crystal portion 254 corresponding to the white sub-pixels. The color color resistors 272 can block a predetermined light signal (such as a backlight mode) that passes through the first liquid crystal portion 252. The blue light signal in the backlight emitted by the group), so that the white picture synthesized by the color sub-pixels meets the requirements. The transparent color resistor 274 cannot block the preset light signal, but the birefringence difference of the second liquid crystal 2542 of the second liquid crystal portion 254 is different from the birefringence difference of the first liquid crystal 2522 of the first liquid crystal portion 252, that is, the second The 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 lower than the transmittance of the first liquid crystal portion 252, and the second liquid crystal 2542 reduces the transmittance of the predetermined light signal. Through the transmittance of the second liquid crystal portion 254, most or all of the preset light signal is blocked, so that the white point coordinates of the white picture displayed by the white sub-pixels and the white picture synthesized by the color sub-pixels are close to or the same, so that the display screen displays The overall white picture meets the requirements, and there will be no problems such as blue cast.

In order to facilitate the understanding of the display device of the embodiment of the present application. The laminated structure of the display device will be described below. Please refer to FIG. 2. FIG. 2 is a schematic diagram of a second structure of the display device provided by an embodiment of the application.

The display device 200 includes a stacked 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, and an upper polarizer 290 Wait.

The backlight module 210 provides the backlight. The liquid crystal layer 250 is used to control the transmission of the backlight. The lower polarizer 220 and the upper polarizer 290 are used to control the light path of the backlight. The color resist layer 270 can make the transmitted monochrome backlight (white light ) Becomes light of the required color, such as red light, green light, blue light, white light, etc., and synthesizes light signals of various colors to display different images. The planarization layer 260 is used to fill some grooves in the color resist layer, and the display array layer 240 includes a driving circuit for controlling each sub-pixel, which can also be understood as separately controlling a region corresponding to each color resist in the liquid crystal layer 250.

It should be noted that the essence of liquid crystal optics is to use the birefringence of the liquid crystal to control the transmission of light. The equivalent formula 1 for calculating the transmittance is:

T=T ₀ sin ² 2Φsin ² (πdΔn/λ);

Among them, T ₀ is the transmittance of the display device itself, Φ is the angle between the optical axis of the liquid crystal and the optical axis of the polarizer, △n is the birefringence difference of the liquid crystal (△n=ne-no, ne is the liquid crystal The refractive index in the long axis direction, no is the refractive index in the short axis direction of the liquid crystal, as shown in FIG.

The white point coordinates in the display device 200 refer to the white point coordinates when the display device 200 displays a white screen. At this time, Φ=45°, the display device 200 has the maximum brightness, and the above equivalent formula 1 becomes equivalent formula 2:

T=T ₀ sin ² (πdΔn/λ);

The color resistance 272 includes a red color resistance, a blue color resistance and a green color resistance. The red color resistance is used to pass red light and filter out light of other colors, and the blue color resistance is used to pass blue light and filter other colors of light. The blocking is used to filter out other colors of light through green light, thereby obtaining the light signals of the three primary colors (red, green, and blue), and combining them to form various required light signals of multiple colors. The first liquid crystal 2522 corresponding to the color resist 272 is the same, and the color of the light signal passing through the different color resists is different, that is, the wavelength of the light wave passing through the different color resists is different. The first liquid crystal 2522 needs to meet the requirements of the three color resists. Therefore, the correspondence between the first liquid crystal portion 252 and the wavelength of the transmitted light is as shown in FIG. 4. It should be noted that the color sub-pixels select light signals with specific light wavelengths to filter out the preset light signals of other colors doped in the backlight. When the color sub-pixels are synthesized to display a white picture, the white picture will not be For the preset light signals of other colors, the coordinate points of the white screen meet the requirements, and the white screen displayed has a good effect without color cast.

The transparent color resist 274 is a transparent material, and it is impossible to select light of different wavelengths. The transmittance of the display device 200 is a sine function related to λ. When Δnd=λ/2, the transmittance of the display device 200 is the highest, that is to say, the required wavelength of light can be more easily transmitted by adjusting Δnd. , So as to realize the color point control of the white sub-pixel W. Specifically, when light signals of other colors doped in the backlight pass through the second liquid crystal 2542, the birefringence difference Δn of the second liquid crystal 2542 is adjusted to reduce the transmittance of the preset light signals of other colors doped. Overrate. For example, making △nd equal to the wavelength of the preset light signal, so that it is completely impermeable, which is equivalent to the white sub-pixel filtering the preset light signal. The coordinate points of the white screen displayed by the white sub-pixel meet the requirements, and the displayed white The picture effect is good, and there is no color cast. For example, the backlight is bluish, that is, the default light signal doped with blue in the backlight, the birefringence difference Δn of the second liquid crystal 2542 is adjusted to reduce the transmittance of the blue predetermined light signal, so that the white sub-pixel The displayed white screen will not be blue, so that the white point coordinates of the white screen displayed through the transparent color resistor 274 are the same as the white point coordinates of the white screen displayed through the color color resistor 272. The white point coordinates can be understood as the color coordinate points when the display device displays a white screen.

It can be seen from the above formula that not only can the light transmittance of the preset light signal be reduced by adjusting the birefringence difference of the second liquid crystal, but also the light transmittance of the preset light signal can be reduced by adjusting the thickness of the second liquid crystal part. Transmittance. Please refer to FIG. 5. FIG. 5 is a schematic diagram of a third structure of the display device provided by an embodiment of the present application. The birefringence difference of the second liquid crystal 2542 is different from the birefringence difference of the first liquid crystal 2522, and the thickness of the second liquid crystal portion 254 is different from the thickness of the first liquid crystal portion 252, The white point coordinates of the white screen displayed through the color resistor 272 and the white point coordinates of the white screen displayed through the transparent color resistor 274 are the same. If only the birefringence difference Δn of the second liquid crystal 2542 is adjusted, the transmittance of the blue preset light signal may not meet the requirements, or the realization may be too large. At this time, better effects can be achieved by adjusting the thickness of the second liquid crystal portion 254 in combination. For example, the backlight is bluish, that is, the preset light signal doped with blue in the backlight, the birefringence difference Δn of the second liquid crystal 2542 is adjusted, and the thickness of the second liquid crystal portion 254 is adjusted at the same time, so that Δnd is equal to the preset light The wavelength of the signal, so that the preset light signal is completely opaque, so that the white picture displayed by the white sub-pixels will not be blue, so that the white point coordinates of the white picture displayed through the transparent color resistor 274 are consistent with the transparent color resistor 274. The white point coordinates of the white screen displayed by the color resist 272 are the same.

The thickness of the second liquid crystal portion 254 can be adjusted by adjusting the structure on both sides of the second liquid crystal portion 254. Specifically, the display device 200 further includes a planarization layer 260 disposed between the color resist layer 270 and the liquid crystal layer 250, and the planarization layer 260 includes a planarization layer adjacent to the first The first surface 262 of the liquid crystal portion 252 and the 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 The thickness is different from the thickness of the second liquid crystal portion 254. The planarization layer 260 adjacent to the second liquid crystal portion 254 is adjusted as needed. Exemplarily, the planarization layer 260 includes a first planarization portion adjacent to the first liquid crystal portion 252 and a second planarization portion corresponding to the second liquid crystal portion 254, and the first planarization portion includes Adjacent to the first surface 262 of the first liquid crystal portion 252, the second planarization portion includes a second surface adjacent to the second liquid crystal portion 254, and adjusts the thickness of the second planarization portion so that the second planarization portion The surface is higher or lower than the first surface 262.

In addition, the thickness of the transparent color resist 274 can also be adjusted, because the transparent color resist does not need to select light signals of a specific wavelength like the color resist 272, and the thickness of the transparent color resist 274 can be adjusted to make the transparent color resist The thickness of 274 is different from the thickness of the color resist 272, combined with the planarization layer 260, so that the thickness of the first liquid crystal portion 252 is different from the thickness of the second liquid crystal portion 254. The thickness of the transparent color resist can 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 source of the backlight of the backlight module 210 is different, the adjusted birefringence difference of the second liquid crystal 2542 may be larger or smaller than the birefringence difference of the first liquid crystal 2522. Similarly, the adjusted The thickness of the second liquid crystal portion 254 may be larger or smaller than the thickness of the first liquid crystal portion 252. Exemplarily, if the backlight has blue light, the adjusted birefringence difference of the second liquid crystal 2542 is greater than the birefringence difference of the first liquid crystal 2522, and the thickness of the adjusted second liquid crystal portion 254 is greater than that of the first liquid crystal portion 252 thickness.

Please continue to refer 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 liquid, and the structures on both sides of the liquid crystal layer 250 cannot be well supported. Therefore, the liquid crystal layer 250 A support pillar 256 is added to support the liquid crystal layer 250. The supporting column 256 can be arranged between the first liquid crystal part 252 and the second liquid crystal part 254, and the first liquid crystal part 252 and the second liquid crystal part 254 are arranged at intervals. Through the multiplexing of the supporting column 256, not only To support the liquid crystal layer 250, the first liquid crystal portion 252 and the second liquid crystal portion 254 can also be separated, and no additional structure is required. Wherein, a continuous support column 256 may be provided between the first liquid crystal portion 252 and the second liquid crystal portion 254 to connect the first liquid crystal 2522 of the first liquid crystal portion 252 and the second liquid crystal portion 254 of the second liquid crystal portion 254 2542 separated. It should be noted that the first liquid crystal portion 252 corresponds to multiple color sub-pixels (RGB), the second liquid crystal portion 254 corresponds to one white sub-pixel (W), and the area of the first liquid crystal portion 252 is larger than that of the second liquid crystal portion 254. Therefore, Some supporting pillars 256 may also be provided in the first liquid crystal portion 252, and the supporting pillars 256 in the first liquid crystal portion 252 are arranged at intervals. Wherein, the size of the supporting column 256 in the first liquid crystal portion 252 can be adapted to the size of the first liquid crystal 2522, the supporting column 256 in the first liquid crystal portion 252 cannot separate the first liquid crystal 2522, and the first liquid crystal portion 252 The first liquid crystal 2522 is not separated by the supporting pillar 256.

Please refer to FIG. 6, which is a schematic diagram of the fourth structure of the display device provided by an embodiment of this application. The liquid crystal layer includes a plurality of the first liquid crystal portions 252 and a plurality of the second liquid crystal portions 254, and the plurality of first liquid crystal portions 252 and the plurality of second liquid crystal portions 254 are arranged along a first direction, The plurality of first liquid crystal parts 252 are connected through a first connecting channel 2524, and a plurality of second liquid crystal parts 254 are connected through a second connecting channel 2544. The first connecting channel 2524 and the second connecting channel are along the first connecting channel 2524. It is arranged in two directions, and the first direction and the second direction are perpendicular to each other.

The color sub-pixels and white sub-pixels need to be evenly arranged. Therefore, the corresponding first liquid crystal portion 252 and the second liquid crystal portion 254 also need to be uniformly arranged. When the color sub-pixels and white sub-pixels are in the first direction (such as column When the first liquid crystal portion 252 and the second liquid crystal portion 254 are arranged in the first direction (such as the column direction), when the first liquid crystal and the second liquid crystal need to be poured into the liquid crystal layer, they can pass through multiple The openings of the first liquid crystal portion 252 and the second liquid crystal portion 254 are filled, and then sealed separately. It is also possible to connect a plurality of the first liquid crystal parts 252 through the first connecting channel 2524, and connect a plurality of the second liquid crystal parts 254 through the second connecting channel 2544. The first liquid crystal 2522 is poured in through an opening, and the second liquid crystal passes through One opening is poured, which reduces the number of openings in the liquid crystal layer and optimizes the operation process. Wherein, the first connecting passage 2524 and the second connecting passage are arranged in a second direction (such as a row direction). The first direction and the second direction are perpendicular to each other.

Wherein, the first connection channel 2524 and the second connection channel are located at 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 arranged, and are respectively connected through the connection channels at both ends. , The layout of the first liquid crystal portion 252 and the second liquid crystal portion 254 is optimized.

The main difference from the display device in the above-mentioned embodiment lies in the color resist layer and the liquid crystal layer. Specifically, the color resister 272 of the display device 200 of this embodiment blocks the preset light signal passing through the first liquid crystal portion 252, and the first liquid crystal portion 252 is different from that of the second liquid crystal portion 254. The thickness is such that the transmittance of the predetermined light signal through the second liquid crystal portion 254 is smaller than the transmittance of the first liquid crystal portion 252.
