Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
First embodiment
Referring to fig. 1, fig. 1 is a structural diagram of a backlight assembly according to an embodiment of the present invention, as shown in fig. 1, a backlight assembly 100 includes a backlight source 101, a reflection plate 102, a light guide plate 103, a first diffusion sheet 104, a prism 105, a second diffusion sheet 106, and a display panel 107, where the backlight source 101 is located between the reflection plate 102 and the light guide plate 103, a reflection surface of the reflection plate 102 is in a direction consistent with a light exit surface of the light guide plate 103, so that light emitted from the backlight source 101 enters the light guide plate 103 and is reflected by the reflection plate 102 and exits from the light exit surface of the light guide plate 103, the prism 105 is disposed between the first diffusion sheet 104 and the second diffusion sheet 106 and is disposed on a side of the light exit surface of the light guide plate 103, so that light emitted from the light guide plate 103 is diffused by the first diffusion sheet 104, collected by the prism 105, and then diffused by the second diffusion sheet 106 and then, the display panel 107 is positioned on a light exit surface side of the second diffusion sheet 106 to display light emitted from the second diffusion sheet 106.
It is understood that the backlight 101 may be located at a side of the light guide plate 103 to make light emitted from the backlight enter from the side of the light guide plate, or located at a side of the light incident surface of the light guide plate 103 to make light emitted from the backlight enter directly towards the light incident surface of the light guide plate, which is not limited herein.
As shown in fig. 2, the backlight 101 includes: a first light element 1011 emitting blue light and a second light element 1012 emitting a predetermined color light, wherein the predetermined color light is a color light other than blue light; and a first control module 1013 connected to the first optical element 1011, configured to adjust a current value of the first optical element 1011; or a second control module 1014 connected to the first optical element 1011 and the second optical element 1012, for adjusting the total current value of the first optical element 1011 and the second optical element 1012.
Specifically, the first light element 1011 and the second light element 1012 emitting light in the backlight 101 may be LED lamps or other light emitting sources. The first optical element 1011 and the second optical element 1012 are at least two light emitting circuits, and the at least two light emitting circuits may be arranged in parallel or in an independent manner without being connected to each other, which is not limited herein. In the embodiment of the invention, as shown in fig. 3, the first optical element 1011 is composed of a plurality of light sources 10110 emitting blue light in series, and the second optical element 1012 is composed of a plurality of light sources 10120 emitting predetermined color light in series. The predetermined color light is other color light besides blue light, for example, the predetermined color light is red, green, or white light.
The first control module 1013 is connected to the first optical element 1011, and the first optical element 1011 is adjusted to control the light intensity of the blue light emitted by the backlight source, so as to adjust the blue light of the backlight source, thereby reducing the damage of the blue light radiation. For example, when the blue light of the backlight needs to be reduced, the first current value for driving the first light element is reduced.
It can be understood that, because when adjusting the luminous intensity of blue light, the whole display effect of backlight must be influenced, and the luminous intensity of the preset chromatic light can be adjusted by increasing or decreasing the second current value for driving the second light element, so that the whole display effect of the backlight is prevented from being greatly influenced. For example, after the light intensity of the blue light is reduced, the overall display effect of the backlight source is seriously reduced, and at this time, the light intensity of the preset color light can be improved by increasing the second current value for driving the second light element, so as to reduce the overall display effect difference of the backlight source.
The second control module 1014 is respectively connected to the first optical element 1011 and the second optical element 1012, and is configured to control a total light intensity of the first optical element 1011 emitting blue light and a total light intensity of the second optical element 1012 emitting predetermined color light by adjusting a total current value of the first optical element 1011 and the second optical element 1012.
As described above, the individual adjustment of the first current value of the first optical element to change the light intensity of the blue light in the backlight affects the overall display effect of the backlight, and particularly, the ratio of the blue light to the other color light is inconsistent. The second control module 1014 can control the total value of the light intensity of the blue light emitted by the first optical element 1011 and the light intensity of the preset color light emitted by the second optical element 1012 by adjusting the total value of the currents of the first optical element 1011 and the second optical element 1012, so as to adjust the overall display brightness of the backlight source. Compared with the method for adjusting the light intensity of the preset color light to correct the display effect of the backlight source, the method for adjusting the overall display brightness of the backlight source reserves the authority of random adjustment of the preset color light in the backlight source, controls the overall display brightness of the backlight source under the condition that the light intensity ratio of the blue light to the preset color light is not changed, and obtains the optimal display effect more easily on the premise of reducing the light intensity of the blue light. Thereby reducing the skill requirements of the user to adjust the backlight.
Optionally, the first optical elements 1011 and the second optical elements 1012 are arranged in a staggered manner.
In order to improve the uniformity of the overall light emitted from the backlight, the first optical element 1011 and the second optical element 1012 may be arranged according to a certain rule, so that the blue light and the light of the predetermined color are mixed more uniformly. For example, as shown in fig. 4, the first light element is a blue light LED, the second light element is a red light LED, and the blue light LED and the red light LED are alternately arranged on the backlight board 401. It is understood that the specific staggered arrangement mode can be arranged at intervals of rows/columns, or at intervals of single light emitting sources with different color lights, and the like.
Optionally, the first optical element 1011 and the second optical element 1012 are packaged into a single body.
Specifically, the first optical element 1011 and the second optical element 1012 packaged as a whole are more compact in structure and simpler in connection relationship, and are more beneficial to uniformly mixing the blue light emitted by the first optical element 1011 and the light of the preset color emitted by the second optical element 1012, so that the uniformity of the whole light emitted by the backlight source is improved.
Alternatively, the second light element 1012 includes a red light emitting monomer and a green light emitting monomer or the second light element 1012 includes a red light emitting monomer, a green light emitting monomer and a white light emitting monomer.
For a backlight based on three primary colors of RGB, red, green and blue, the predetermined color light emitted by the second light element 1012 includes red and green lights, and the light emitting source of the second light element 1012 is set to include a single body emitting red light and a single body emitting green light, so that compared with the case that the light emitting source of the second light element 1012 is directly set to emit red and green light, the loss of light energy is reduced, and the display saturation of the backlight is improved.
Similarly, for a backlight based on four colors of red, green, blue, and white RGBW, the predetermined color light emitted by the second light element 1012 includes red, green, and white light, and the light emitting source of the second light element 1012 can be set to include a single body emitting red light, a single body emitting green light, and a single body emitting white light.
The backlight assembly provided by the embodiment of the invention comprises: a backlight source, a reflecting plate, a light guide plate, a first diffusion sheet, a prism, a second diffusion sheet and a display panel, the backlight source is positioned between the reflecting plate and the light guide plate, the direction of the reflecting surface of the reflecting plate is consistent with that of the light emergent surface of the light guide plate, so that the light emitted by the backlight source enters from the light guide plate, is reflected by the reflecting plate and exits from the light-emitting surface of the light guide plate, the prism is arranged between the first diffusion sheet and the second diffusion sheet, and is arranged on one side of the light-emitting surface of the light guide plate, so that light emitted by the light guide plate is diffused by the first diffusion sheet, gathered by the prism, diffused by the second diffusion sheet and then emitted to the display panel, the display panel is positioned on one side of the light emergent surface of the second diffusion sheet and displays light emitted by the second diffusion sheet, and the backlight source comprises: a first light element emitting blue light and a second light element emitting a preset color light, wherein the preset color light is a color light other than the blue light; the first control module is connected with the first optical element and is used for adjusting the current value of the first optical element; or the second control module is connected with the first optical element and the second optical element and used for adjusting the total current value of the first optical element and the second optical element. Through separating the first light component that will give out blue light alone with the second light component that sends other predetermined color lights, and then control the luminous intensity of back of the body blue light to the regulation of first light component current value or first light component and second light component's current total value, realize under the prerequisite that does not change display panel transmissivity and the spectrum of backlight that the blue light of backlight is adjustable, reduced the injury of blue light radiation to the influence to the display effect has been reduced.
Second embodiment
Referring to fig. 5, fig. 5 is a flowchart of a method for controlling a backlight assembly according to an embodiment of the present invention, where the method is applied to a mobile terminal, and the backlight assembly of the mobile terminal is shown in fig. 5, and includes the following steps:
step 501, receiving an adjustment instruction for blue light intensity.
Specifically, the adjustment instruction for the blue light intensity may be adjustment information input by a user as needed, or an adjustment instruction triggered by information about blue light adjustment detected by the detection device, and a specific form is not limited.
And step 502, extracting the blue light intensity value in the adjusting instruction.
For example, if the adjustment instruction for the blue light intensity is a user dragging a button or icon for adjusting the blue light, the blue light intensity value corresponding to the dragged position of the button or icon may be determined, or an adjustment instruction for the blue light intensity triggered by spectral data or/and luminance data of the ambient light detected by the sensing device may be generated, and the spectral data or/and luminance data of the ambient light may be extracted according to the adjustment instruction to determine the blue light intensity value. It is understood that, according to different forms of the adjustment instruction, the manner of extracting the blue light intensity value in the adjustment instruction also differs, and is not listed here.
Step 503, adjusting a current value of the first optical element according to the blue light intensity value, or adjusting a total current value of the first optical element and the second optical element according to the blue light intensity value.
After the blue light intensity value in the adjusting instruction is determined, the current value of the first light element or the total current value of the first light element and the second light source is adjusted so that the blue light emitted by the first light element reaches the blue light intensity value in the adjusting instruction.
Optionally, the step of adjusting the current value of the first optical element according to the blue light intensity value includes: calculating the current value of the first light element corresponding to the blue light intensity value according to the corresponding relation between the preset blue light intensity value and the current value of the first light element; and adjusting the current value of the first light element to be the current value of the first light element corresponding to the blue light intensity value.
Because there is a one-to-one correspondence relationship between the blue light intensity value emitted by the first optical element and the current value of the first optical element, the current value of the corresponding first optical element can be calculated by using the blue light intensity value in the adjustment instruction, so that the current value of the first optical element is adjusted.
Optionally, a corresponding relationship between the preset blue light intensity value and the current value of the first light element is as follows: i is1/Imax1＝B/Bmax(ii) a Wherein, I1Is the current value of the first light element, Imax1Is the maximum current value of the first optical element, B is the blue light intensity value, BmaxIs the maximum blue light intensity value, Imax1And BmaxAll are constant values, which are determined by the intrinsic properties of the first optical element.
Generally, the light intensity value is proportional to the current value of the optical element, and thus the blue light intensity value emitted by the first optical element is also proportional to the current value of the first optical element. The maximum blue light intensity value emitted by the first light element and the maximum allowed current value are fixed based on the structural limitations of the first light element. Based on the maximum blue light intensity value and the maximum current value, the blue light intensity value emitted by the first light element is increased or decreased along with the increase or decrease of the current value.
Optionally, the step of adjusting the total current value of the first optical element and the second optical element according to the blue light intensity value includes: calculating the total current value corresponding to the blue light intensity value according to the corresponding relation between the preset blue light intensity value and the total current value; and adjusting the total current value of the first optical element and the second optical element to the total current value corresponding to the blue light intensity value.
Because the one-to-one correspondence relationship exists between the blue light intensity value emitted by the first light element and the current value of the first light element, and the one-to-one correspondence relationship also exists between the current value of the first light element and the total current value of the first light element and the second light element when the backlight source tone configuration effect is not changed, the one-to-one correspondence relationship necessarily exists between the blue light intensity value emitted by the first light element and the total current value of the first light element and the second light element. And calculating the total current value of the corresponding first optical element and the second optical element by using the blue light intensity value in the adjusting instruction, so as to adjust the total current value of the first optical element and the second optical element.
Optionally, the corresponding relationship between the preset blue light intensity value and the total current value is as follows: i isGeneral assembly/Imax total＝B/Bmax(ii) a Wherein, IGeneral assemblyIs the total value of the currents of the first and second light elements, Imax totalIs the total maximum current value of the first and second optical elements, B is the blue light intensity value, BmaxIs the maximum blue light intensity value, Imax totalAnd BmaxAre all constant values.
Specifically, there is a corresponding relationship between the blue light intensity value emitted by the first optical element and the current value of the first optical element:
I1/Imax1＝B/Bmax(1)；
wherein, I1Is the current value of the first light element, Imax1Is the maximum current value of the first optical element, B is the blue light intensity value, BmaxIs the maximum blue light intensity value, Imax1And BmaxAll are constant values, which are determined by the performance of the first optical element.
The current value of the first optical element and the total current value of the first optical element and the second optical element have a corresponding relation:
I1/Imax1＝Igeneral assembly/Imax total(2)；
Wherein, I1Is the current value of the first light element, Imax1Is the maximum current value of the first light element, IGeneral assemblyIs the total value of the currents of the first and second light elements, Imax totalIs the total maximum current value of the first and second optical elements, Imax1And Imax totalBoth are constant values, determined by the first and second optical elements themselves.
Combining the corresponding relations (1) and (2), the corresponding relation between the intensity value of the blue light emitted by the first optical element and the total current value of the first optical element and the second optical element can be obtained:
Igeneral assembly/Imax total＝B/Bmax(3)；
Wherein, IGeneral assemblyIs the total value of the currents of the first and second light elements, Imax totalIs the total maximum current value of the first and second optical elements, B is the blue light intensity value, BmaxIs the maximum blue light intensity value, Imax totalAnd BmaxBoth are constant values, which are determined by the performance of the first and second optical elements.
Obviously, the intensity value of the blue light emitted by the first light element is proportional to the current value of the first light element, and the intensity value of the blue light emitted by the first light element is also proportional to the total current value of the first light element and the second light element when the backlight color tone arrangement effect is not changed, and the intensity value of the blue light emitted by the first light element increases and decreases with the increase and decrease of the total current value of the first light element and the second light element.
The control method of the backlight assembly can be implemented by any of the backlight assemblies, and the specific structure thereof can be referred to the implementation of the backlight assembly, which is not described herein again.
The control method of the backlight assembly provided by the embodiment of the invention is applied to a mobile terminal, the mobile terminal comprises the backlight assembly, and the method comprises the following steps: receiving an adjusting instruction aiming at the blue light intensity; extracting a blue light intensity value in the adjusting instruction; and adjusting the current value of the first light element according to the blue light intensity value, or adjusting the total current value of the first light element and the second light element according to the blue light intensity value. Through separating the first light component that will give out blue light alone with the second light component that sends other predetermined color lights, and then control the luminous intensity of back of the body blue light to the regulation of first light component current value or first light component and second light component's current total value, realize under the prerequisite that does not change display panel transmissivity and the spectrum of backlight that the blue light of backlight is adjustable, reduced the injury of blue light radiation to the influence to the display effect has been reduced.
