The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Throughout the description of the present application, it is intended that the terms "mounted," "disposed," "connected," and "connected" be construed broadly and encompass, for example, fixed connections, removable connections, or integral connections unless expressly stated or limited otherwise; can be mechanically connected or electrically connected; they may be directly connected or may be connected via an intermediate medium. To one of ordinary skill in the art, the foregoing may be combined in any suitable manner with the specific meaning ascribed to the present application.
The present application first discloses a backlight module, which includes a plurality of backlight modules, referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of the backlight module of the present application, and as shown in fig. 1, the backlight module can be divided into a plurality of first partitions 11 and a plurality of second partitions 12.
The first sub-section 11 is provided with a first light emitting source 111, and the second sub-section 12 is provided with a second light emitting source 121. The first light-emitting source 111 and the second light-emitting source 121 may be specifically a string of light formed by connecting a plurality of LED light sources in series, or may be a single LED light source, and the LED light source may be specifically a Mini LED light source or other types of LED light sources, which may be specifically determined according to actual needs, and is not limited herein. The voltage signals received by the first light emitting source 111 and the second light emitting source 121 in the same backlight module can be provided by the same driving chip.
In a group of two adjacent first partitions 11 in the backlight module, a first light emitting source 111 is arranged in one first partition 11 and driven by a corresponding driving chip to emit light with a first brightness, and a first light emitting source 111 arranged in the other first partition 11 is driven by a corresponding driving chip to emit light with a second brightness. The second light emitting sources 121 disposed in the second sub-area 12 between two adjacent first sub-areas 11 of the group are driven by the corresponding driving chips to emit light with a first target brightness.
In order to make the light emitted by the second light emitting source 121 have the effect of passing through the light between the two first light emitting sources 111, and further weaken or eliminate the blocking phenomenon between the two first partitions 11, the driving chip needs to control the second light emitting source 121 to emit light with a brightness between the first brightness and the second brightness, that is, the first target brightness is the brightness between the first brightness and the second brightness.
Based on the above manner, each group of two adjacent first partitions 11 in the backlight module can form an effect of gradually changing the brightness by the light emitted by the second light emitting source 121 of the second partition 12 disposed therebetween and the brightness of the light emitted by the first light emitting source 111 in the two adjacent first partitions, so that the boundary phenomenon of the light emitted by each group of adjacent first partitions 11 is weakened, and the blocking phenomenon in the backlight module is weakened or eliminated, thereby improving the display effect corresponding to the backlight module.
Different from the prior art, in the technical scheme of the present application, a second partition is disposed in two adjacent first partitions in the backlight module, a first light emitting source is disposed in the first partition, and a second light emitting source is disposed in the second partition, wherein the first light emitting source in one of the two adjacent first partitions emits light at a first brightness, the first light emitting source in the other of the two adjacent first partitions emits light at a second brightness, the second light emitting source in the second partition between the two adjacent first partitions emits light at a first target brightness, and the first target brightness is a brightness between the first brightness and the second brightness. Based on the above manner, the excess of the brightness of the light between the two adjacent first partitions can be completed through the light with the first target brightness emitted by the second light emitting source of the second partition between the two adjacent first partitions, so that the boundary condition between the two adjacent first partitions and the corresponding second partition is weakened or eliminated, the blocking phenomenon in the backlight module is weakened or eliminated, and the corresponding display effect of the backlight module is improved.
In an embodiment, the backlight module further includes a temperature sensing module (not shown), and the temperature sensing module is used for monitoring the temperature of the backlight module.
The second light emitting source 121 is configured to emit light with a first target brightness when the temperature is lower than a first preset temperature threshold.
Specifically, when the temperature of the backlight module monitored by the temperature sensing module is less than the first preset temperature threshold, the current heating power of the backlight module may be considered to be low, and at this time, if the second light emitting source 121 in the second partition 12 is started to emit light, the heating power of the backlight module may not be too high.
It should be noted that, if the temperature of the backlight module is too high, the operation of the device where the backlight module is located is easily affected, so that the device cannot normally operate, and therefore, based on the above manner, the second light sources 121 in the second partition 12 can be activated to emit light only when the temperature of the backlight module is less than the first preset temperature threshold, that is, the temperature of the backlight module itself does not affect the normal operation of the backlight module or the device where the backlight module is located, so that the light emitted by two adjacent first partitions 11 and the light emitted by the second partition 12 therebetween can form an effect of gradually changing the brightness, and further the boundary phenomenon of the light emitted by each group of adjacent first partitions 11 is weakened or eliminated, so as to weaken or eliminate the blocking phenomenon in the backlight module, and improve the display effect corresponding to the backlight module.
Optionally, the second light source 121 is further configured to emit light with a second target brightness when the temperature is not less than the first preset temperature threshold, where the second target brightness is a preset multiple of the first target brightness, and the preset multiple is less than 1 and greater than 0.
Specifically, when the temperature of the backlight module monitored by the temperature sensing module is not less than the first preset temperature threshold, the current heating power of the backlight module may be considered to be higher, and if the second light emitting source 121 in the second partition 12 is activated to emit light, when the brightness of the second light emitting source 121 is higher, the heating power of the backlight module is easily too high, thereby affecting the normal operation of the backlight module or the device where the backlight module is located.
Therefore, when the temperature of the backlight module monitored by the temperature sensing module is not less than the first preset temperature threshold, the second light source 121 may be controlled to emit light at the first target brightness which is less than 1 and greater than a preset multiple of 0, that is, the second light source 121 may emit light at the first target brightness when the temperature is less than the first preset temperature threshold, and emit light at the second target brightness which is lower than the first target brightness when the temperature is not less than the first preset temperature threshold, so that the second light source 121 may emit light with a certain brightness by reducing the brightness of the light emitted by the second light source 121 under the condition that the temperature of the backlight module is higher, thereby achieving the technical effect of reducing or eliminating the blocking phenomenon in the backlight module as much as possible on the premise of not affecting the normal operation of the backlight module or the device where the backlight module is located, and thus improving the display effect corresponding to the backlight module.
Further, in an embodiment, the preset multiple may be a preset constant value, for example, the preset multiple may be 0.5, so that the second target brightness is half of the first target brightness, or the preset multiple may be another preset value, which may be determined according to actual requirements, and is not limited herein.
Further, in another case, the second light source is further configured to emit light with a third target brightness when the temperature is greater than a second preset temperature threshold and the second target brightness is greater than a preset third target brightness.
And the second preset temperature threshold is greater than the first preset temperature threshold.
Specifically, a second predetermined temperature threshold may be further provided in addition to the first predetermined temperature threshold, and the second predetermined temperature threshold is greater than the first predetermined temperature threshold.
When the temperature of the backlight module monitored by the temperature sensing module is greater than the second preset temperature threshold, the temperature of the backlight module is considered to reach the warning standard, and at this time, the maximum value of the light emitting brightness of the second light emitting source 121 needs to be limited, that is, the light emitting brightness of the second light emitting source 121 does not exceed the preset third target brightness, so as to avoid serious failure of the backlight module or the device where the backlight module is located due to over-high temperature.
Based on the above manner, when the temperature is greater than the second preset temperature threshold, that is, the temperature reaches the warning standard, it can be determined whether the second target brightness is greater than the third target brightness.
If the second target brightness is greater than the third target brightness, the second light source 121 cannot be allowed to continue to emit light at the second target brightness, but the second light source 121 is controlled to emit light at the third target brightness to avoid the temperature of the backlight module from continuing to increase, and if the second target brightness is not greater than the third target brightness, the second light source 121 can continue to emit light at the second target brightness, which can better achieve the effect of gradual brightness change compared with the third target brightness.
In summary, based on the above manner, the safety of the backlight module can be improved.
Still further, the preset multiple may be a variation value.
When the temperature is greater than the first preset temperature threshold and not greater than the second preset temperature threshold, the preset multiple and the temperature are in a negative correlation relationship.
Specifically, when the temperature of the backlight module is between the first preset temperature threshold and the second preset temperature threshold, the temperature of the backlight module is at a higher level below the warning standard, and at this time, the preset multiple and the temperature may be in a negative correlation relationship, that is, the closer the temperature is to the first preset temperature threshold, the higher the preset multiple is, and the closer the temperature is to the second preset temperature threshold, the lower the preset multiple is.
Based on the above manner, the light emitting brightness of the second light emitting source 121 can be reasonably changed along with the change of the temperature, thereby avoiding the failure of the backlight module caused by the temperature exceeding the second preset temperature threshold as much as possible, and further improving the safety of the backlight module.
The maximum value of the preset multiple may be 0.5, or may be other values greater than 0 and less than 1, and is not limited herein.
In an embodiment, the second light source 121 is configured to emit light with a first target brightness when the first brightness or the second brightness is greater than a preset brightness threshold, and is turned off when neither the first brightness nor the second brightness is greater than the preset brightness threshold.
Specifically, in the two first light sources 111 sandwiching the second light source 121, if the brightness of at least one of the first light sources 111 is greater than the preset brightness threshold, the second light source 121 may be controlled to emit light with the first target brightness, so as to reduce or eliminate the blocking phenomenon in the backlight module, and improve the display effect corresponding to the backlight module.
In the two first light sources 111 sandwiching the second light source 121, if the brightness of any one of the first light sources 111 is not greater than the preset brightness threshold, that is, the brightness of the two first light sources 111 is not greater than the preset brightness threshold, it can be considered that the brightness of the light emitted from the two first partitions 11 is low, and at this time, even if the second light source 121 does not emit light, the blocking phenomenon existing between the two first partitions 11 is not obvious, so that the corresponding second light source 121 can be controlled to be turned off, thereby achieving the technical effect of saving energy.
In one embodiment, the first target brightness is an average brightness of the first brightness and the second brightness.
Specifically, the first target brightness mentioned in any of the foregoing embodiments may be an average value between the first brightness and the second brightness, that is, in a group of two adjacent first partitions and the second partition therebetween, the brightness of the light emitted by the middle second partition is an average value between the brightness of the light emitted by the two first partitions.
