Detailed Description

In the related art, the main reason why the blue edge occurs at the edge of the display area of the display device is that: as shown in fig. 1 to 4, the display device 100 includes a backlight module and a display panel, the display panel is disposed on a light-emitting side of the backlight module; the backlight module comprises a reflecting plate 120, a monochromatic light source 110 and a quantum dot layer 130, wherein the reflecting plate 120, the monochromatic light source 110 and the quantum dot layer 130 are sequentially stacked, the edge of the reflecting plate 120 is provided with a bending part 121 which is bent towards one side of the monochromatic light source, the bending part 121 supports other film layer structures positioned on the light emitting side of the reflecting plate 120, the quantum dot layer 130 can effectively convert high-energy blue light into red light and green light, the converted red light, the green light and the blue light are synthesized into white light, and the display panel is used for filtering light with different wavelengths (colors) to form a color with high color vividness. However, the light emitted from the monochromatic light source to the edge is reflected by the bent portion 121 of the reflector 120, so that a lot of blue light enters the edge of the quantum dot layer 130, and the quantum dot layer cannot completely excite and neutralize the blue light, so that a lot of blue light is emitted from the edge a1 of the display area a of the display device 100, and a blue edge is emitted from the edge of the display device 100.

In order to solve the above problem, an embodiment of the present application provides a display device, which can solve the phenomenon that a blue edge appears at an edge of the display device, so as to improve a display effect of the display device and improve visual experience of a user.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Referring to fig. 5, an embodiment of the present invention provides a display device 100, including: a monochromatic Light source 110, wherein the monochromatic Light source 110 may be a blue LED (Light Emitting Diode) Light source or the like; when the monochromatic light source 110 is a blue LED light source, the emitted light is blue.

In the embodiment of the present application, the monochromatic light source 110 is described as a blue LED light source.

The reflecting plate 120 is disposed on a side of the monochromatic light source 110 departing from the light emitting side (i.e. the light emitting side of the monochromatic light source 110 is the side departing from the reflecting plate 120), for example, the reflecting plate 120 is disposed at the bottom of the monochromatic light source 110, and the reflecting plate 120 is used for reflecting the light emitted from the monochromatic light source 110 to the side of the reflecting plate 120 to the light emitting side, so that the loss of the light can be reduced, and the light utilization rate can be improved.

In addition, the edge of the reflective plate 120 is usually provided with a bending portion 121, and the bending portion 121 is bent toward the light emitting side close to the monochromatic light source 110, so that the bending portion 121 can support the film structure on the reflective plate 120.

In order to increase the high color gamut of the display device 100, so that the display device 100 forms a color with high color vividness, in the embodiment of the present application, a quantum dot layer 130 is disposed on a side of the monochromatic light source 110 facing away from the reflective plate 120, wherein the quantum dot layer 130 may be a quantum dot diffusion plate or a quantum dot diffusion film.

It is understood that the quantum dot layer 130 includes, but is not limited to, particles made of cadmium selenide and the like, the particle size of the particles is different, the length of the light wave generated by the quantum dot layer 130 excited by the light emitted from the monochromatic light source 110 is different, for example, the larger the particle size is, the longer the light wave generated by excitation is; in the embodiment of the present invention, when the blue light emitted from the monochromatic light source 110 is irradiated onto the quantum dot layer 130, the quantum dot layer 130 can excite red, green, and blue with high purity, and the excited red, green, and blue can be mixed to form white light.

For example, the quantum dot layer 130 may be specifically manufactured by mixing particles of cadmium selenide and the like in an organic solvent, uniformly mixing, and then coating the mixture on the light emitting side of the monochromatic light source 110, so as to form a quantum dot thin film on the monochromatic light source 110, wherein the quantum dot thin film forms the quantum dot layer 130 in the embodiment of the present application.

The quantum dot layer 130 is provided with a color filter 150 on a side thereof away from the monochromatic light source 110, wherein the color filter 150 is an optical filter for expressing colors, and the color filter 150 can precisely filter the white light formed by the quantum dot layer 130, that is, the color filter 150 can precisely select a small range of wavelength bands to be passed, and reflect other undesired wavelength bands, so that the display device 100 can display a desired image.

In some embodiments, the color filter plate 150 includes a plurality of color filters arranged at intervals, the plurality of color filters includes a first color filter 151, and the first color filter 151 is configured to transmit light with a color consistent with the color of the monochromatic light source 110. For example, the first color filter 151 is a blue (B) color filter, and the blue color filter is used to pass light of a blue wavelength band and reflect light of other colors.

The color filters further include a second color filter 152 and a third color filter 153, wherein the second color filter 152 may be a red (R) color filter, and the third color filter 153 may be a green (G) color filter, it is understood that the red color filter may pass light of a red wavelength band and reflect light of blue and green, and the green color filter may pass light of a green wavelength band and reflect light of red and blue, so that R, G, B three colors are mixed in different proportions to display a desired color.

It will be appreciated that the color filters form a small display unit, and the color filter 150 includes a plurality of RGB display units, wherein R, G, B of each display unit are separated by the black matrix 154.

In addition, in order to control the switching of different color lights in the color filter 150, in the embodiment of the present application, a TFT (Thin Film Transistor) array substrate is disposed between the quantum dot layer 130 and the color filter 150. It is understood that a liquid crystal layer 160 is disposed between the TFT array substrate 140 and the color filter 150.

In some embodiments, the TFT array substrate 140 has a central region and an edge region surrounding the central region, the edge region covers the projection of the bending portion 121 of the reflector 120 on the TFT array substrate 140, wherein the central region and the edge region include a plurality of light-transmitting regions, light emitted from the quantum dot layer 130 can enter the color filter 150 through each light-transmitting region, and the color filter 150 filters light of different wavelength bands to display a desired color.

The plurality of light-transmitting regions include a first light-transmitting region 141, a second light-transmitting region 142, and a third light-transmitting region 143, wherein the first light-transmitting region 141 is disposed opposite to the first color filter 151, the second light-transmitting region 142 is disposed opposite to the second color filter 152, and the third light-transmitting region 143 is disposed opposite to the third color filter 153.

When light emitted from the quantum dot layer 130 enters the first color filter 151 of the color filter 150 through the first light-transmitting region 141, the first color filter 151 passes light waves having a color identical to that of the monochromatic light source 110 (e.g., blue), and reflects and filters light waves of other colors (e.g., red and green), so that the light emitted after being filtered by the first color filter 151 is blue.

In the same principle, the light transmitted by the second light-transmitting region 142 enters the second color filter 152, the light transmitted by the third light-transmitting region 143 enters the third color filter 153, and the second color filter 152 and the third color filter 153 respectively pass through the wavelength bands to be passed and reflect the light waves of the other color wavelength bands.

In order to solve the phenomenon that the blue edge appears at the edge of the display device 100, in the embodiment of the present application, the area of the first light-transmitting region 141 at the edge region may be smaller than the area of the first light-transmitting region 141 at the central region, so that the amount of blue light entering the first color filter 151 through the first light-transmitting region 141 at the edge region may be controlled by controlling the area of the first light-transmitting region 141 at the edge region, thereby preventing the blue edge from appearing at the edge of the display region of the display device 100, further improving the display effect of the display device 100, and improving the visual experience of the user.

The display device 100 provided by the embodiment of the application reduces the area of the first light-transmitting area 141 in the edge area of the TFT array substrate 140 to reduce the amount of light transmitted, thereby reducing the blue light displayed in the first color filter, and further avoiding the phenomenon that the blue edge appears at the edge of the display device 100, so that the display effect of the display device 100 can be improved, and the visual experience of a user can be improved.

In some embodiments, the area of each first light-transmitting region 141 in the edge region is sequentially reduced from the central region to the edge region, so that the light transmittance entering the first color filter 151 through the first light-transmitting region 141 is sequentially reduced from the central region to the edge region, thereby reducing blue light displayed by the first color filter 151, avoiding a blue edge phenomenon at the edge of the display device 100, further improving the display effect of the display device 100, and improving the visual experience of a user.

In some embodiments, please refer to fig. 6, the area of the first light-transmitting regions 141 in the edge region is reduced, so that the size of each first light-transmitting region 141 in the edge region along the first direction is sequentially reduced (as shown by the arrow in fig. 6), thereby reducing the area of the first light-transmitting regions 141 in the edge region, further controlling the amount of blue light entering the first color filter 151, and avoiding the occurrence of blue edge at the edge of the display region of the display device 100.

In other embodiments, please refer to fig. 7, the area of the first light-transmitting regions 141 in the edge region is reduced, and the size of each first light-transmitting region 141 in the edge region along the second direction is sequentially reduced (as shown by the arrow in fig. 7), so as to reduce the area of the first light-transmitting regions 141 in the edge region, further control the amount of blue light entering the first color filter 151, and avoid the occurrence of blue edge at the edge of the display region of the display device 100.

In still other embodiments, the area of the first transparent regions 141 in the edge region may be reduced, and the size of each first transparent region 141 in the edge region along the first direction and the size along the second direction are both reduced, so as to reduce the area of the first transparent region 141, further control the transmission amount of the blue light entering the first color filter 151, and avoid the blue edge phenomenon at the edge of the display region of the display device 100.

In some embodiments, the width of the edge region may coincide with a region corresponding to a projection of the bending portion 121 on the TFT array substrate 140, so that a blue edge phenomenon at the edge of the display device 100 may be avoided while a display effect of the display device 100 is satisfied.

For example, the width of the projection of the bending part 121 on the TFT array substrate 140 may be 5mm to 10mm, and thus, the width of the edge region may also be 5mm to 10 mm; for example, the width of the projection of the bending portion 121 on the TFT array substrate 140 is 5mm, and the width of the edge area is 5 mm; accordingly, the width of the edge region may vary with the variation of the width of the projection of the bent portion 121 on the TFT array substrate 140, for example, the width dimension of the edge region may be 6mm, 7mm, 8mm, 9mm, or 10mm, etc.

In addition, in order to avoid the blue edge phenomenon at the edge of the display device 100, in the embodiment of the present application, please refer to fig. 5, in which the area of each first color filter 151 corresponding to the edge region is smaller than the area of the first color filter 151 corresponding to the central region, and by reducing the area of the first color filter 151 at the edge region, the blue light displayed by the first color filter 151 can be reduced, so that the amount of blue light transmitted at the edge region can be reduced, and the blue edge phenomenon at the edge of the display region of the display device 100 can be avoided.

It can be understood that, by reducing the area of each first color filter 151 corresponding to the edge region, the transmission amount of blue light in the edge region can be reduced, while the area of each first color filter 151 corresponding to the central region is unchanged, so that the display effect of the display device 100 can be ensured, and the blue edge phenomenon at the edge of the display region of the display device 100 can be avoided.

Optionally, the area of each first color filter 151 corresponding to the edge region is sequentially reduced from the central region to the edge region, and thus, blue light displayed by the first color filter 151 is sequentially reduced from the central region to the edge region, so that a phenomenon that blue edge appears at the edge of the display device 100 can be avoided, the display effect of the display device 100 is improved, and further, the visual experience of a user is improved.

In some embodiments, please refer to fig. 8, the area of the first color filters 151 corresponding to the edge region is reduced, so that the size of each of the first color filters 151 corresponding to the edge region along the first direction is sequentially reduced (as shown by the arrow in fig. 8), thereby reducing the area of the first color filters 151 in the edge region, further reducing the amount of blue light transmitted, and avoiding the occurrence of blue edge at the edge of the display region of the display device 100.

In other embodiments, please refer to fig. 9, the area of the first color filters 151 corresponding to the edge region is reduced, and the size of each first color filter 151 in the edge region along the second direction is sequentially reduced (as shown by the arrow in fig. 9), so as to reduce the area of the first color filters 151 in the edge region, further reduce the amount of blue light transmitted, and avoid the blue edge phenomenon at the edge of the display region of the display device 100.

In some embodiments, the projection of the first light-transmitting region 141 of the edge region on the color filter 150 may cover the first color filter 151 corresponding to the position thereof, for example, the projection of the first light-transmitting region 141 on the color filter 150 is larger than the first color filter 151 corresponding to the position thereof; or, the projection of the first light-transmitting region 141 on the color filter 150 coincides with the corresponding first color filter 151, so that the first light-transmitting region 141 in the edge region reduces the transmittance of the light entering the color filter 150, and simultaneously, the blue light to be displayed can be reduced through the first color filter 151, thereby preventing the blue edge from appearing at the edge of the display device 100.

In other embodiments, the area of the first transmissive region 141 in the edge region may also be smaller than the area of the corresponding first color filter 151.

Note that the reduced portion of the first color filter in the edge region may be filled with the black matrix 154 to avoid light leakage.

In the above embodiment, after the bending angle of the bending portion 121 of the reflection plate 120 and the distance from the edge to the edge of the display area of the display device 100 are fixed, the deviation value can be obtained by measuring the color coordinate at the edge of the display device 100 and comparing the measured actual color coordinate with the target value. The excess proportion of blue light in the light can be calculated by the following formula according to the deviation value, and the calculation formula is as follows:

X＝2.7690R+1.7517G+1.1301B (1)

Y＝1.0000R+4.5907G+0.0601B (2)

Z＝0.0000R+0.0565G+5.5928B (3)

x＝X/(X+Y+Z) (4)

y＝Y/(X+Y+Z) (5)

wherein, in the formulas (1), (2), (3), (4) and (5), R is the measured brightness of the red light; g is the measured brightness of the green light; b is the measured brightness of the blue light; x, Y, Z are three stimulus values, x and y are color scale values.

In the above formula, according to the RGB ratio requirement of the edge region, the first light-transmitting region 141 and the first color filter 151 with the corresponding ratio aperture ratio are manufactured to reduce the amount of blue light transmission, and it can be known from the figure that the area of the first light-transmitting region 141 and the first color filter 151 corresponding to blue is smaller as the area is closer to the edge, the amount of blue light transmission is smaller, so that the phenomenon of blue edge at the edge of the display device 100 can be avoided, and the display effect of the display device 100 can be improved.

It can be understood that, in the embodiment of the present application, the area of the edge region of the first light-transmitting region 141 in the TFT array substrate 140 and/or the area of the edge region of the first color filter 151 in the color filter 150 are reduced to control the ratio of RGB components emitted by the liquid crystal panel at the edge of the display region of the display device 100, so as to achieve the purpose of synthesizing white light.
