The display module 220 and the color-tunable backlight module 210 are both connected to the energy storage module 400, so that the energy storage module 400 can supply power to the display module 220 and the color-tunable backlight module 210. Meanwhile, the color tunable backlight module 210 may be connected to the control module 300 through the driving port 500, so that the control module 300 can accurately control the backlight color switching of the color tunable backlight module 210.

In some embodiments of the present invention, as shown in fig. 6, the mobile power source may further include a power detection module 600, and the power detection module 600 is connected to the energy storage module 400 and the display module 220 respectively.

Specifically, the electric quantity detection module 600 may be implemented by using a coulometry method (a coulometer is connected to a current check resistor in series between a positive electrode and a negative electrode of a lithium battery), a battery discharge curve model calculation method, and a voltage detection method. As shown in fig. 6, the voltage detection chip is used to detect the voltage of the negative electrode of the energy storage module 400, so as to determine the information of the electric quantity of the energy storage module 400.

In some embodiments of the present invention, the color tunable backlight module 210 may include a light guide plate 211, a reflective film 212, a diffusion film 213, and at least one light emitting element 214. The display module 220, the diffusion film 213, the light guide plate 211 and the reflective film 212 are sequentially disposed from top to bottom, and the at least one light emitting element 214 is disposed at a side portion of the light guide plate 211. As shown in fig. 2 and 3, two light emitting elements 214 are respectively disposed at two sides in the light guide plate 211. When the two light emitting elements 214 emit light, the light emitted from the light emitting elements 214 is completely transmitted into the light guide plate 211 by the reflective plate 212 to reduce unnecessary loss, the light emitted from the two light emitting elements 214 on the two sides of the light guide plate 211 is guided to the front surface of the display module 220 by the light guide plate 211, and the edge-lit light is modified into a uniform surface light source by the diffusion film 213, so that a good backlight display effect is ensured, and a user can more conveniently view display contents on the display module 220. In other implementations, each light emitting component 214 may also be disposed at an outer side portion of the light guide plate 211, and the embodiments of the present invention are not limited thereto.

Specifically, the light emitting assembly 214 may employ at least two light sources of different colors, and the light source may be a Cold Cathode Fluorescent Lamp (CCFL) or a Light Emitting Diode (LED) light source, and the like, which is not particularly limited.

In some embodiments of the present invention, each light emitting component 214 is connected to the energy storage module 400 through the electrode port 700, each light emitting component 214 is connected to the control module 300 through the driving port 500, and the control module 300 controls the light emitting component 214 to switch the light emitting color through the driving port 500. That is, the control module 300 can individually control each light emitting assembly 214 through the respective driving port 500 of each light emitting assembly 214, so that each light emitting assembly 214 can adopt the same light emitting color or different light emitting colors, thereby increasing the combination diversity of the light emitting effects of the plurality of light emitting assemblies 214.

Specifically, the light emitting assembly 214 may be connected to the positive power supply of the energy storage module 400 through the electrode port 700, or may be connected to the negative power supply of the energy storage module 400.

In some embodiments of the present invention, the light emitting component 214 may include a red light source, a green light source, and a blue light source, the driving port 500 may include a red light source port 510, a green light source port 520, and a blue light source port 530, the red light source port 510 is connected to the red light source, the green light source port 520 is connected to the green light source, and the blue light source port 530 is connected to the blue light source. As shown in fig. 2 and 3, the light emitting component 214 may be a common-anode RGB lamp, and the four pins of the common-anode RGB lamp may be an electrode port 700, a red light source port 510, a green light source port 520, and a blue light source port 530.

Specifically, taking the light emitting component 214 connected to the positive power supply of the energy storage module 400 through the electrode port 700 as an example, in one implementation, the control module 300 may input a low level signal to any light source port, so that the light source connected to the light source port is turned on, for example, when the control module 300 inputs a low level signal to the red light source port 510 of the light emitting component 214, the red light source of the light emitting component 214 is turned on, and the light emitting component 214 emits red light. In another implementation manner, the control module 300 may input different level signals to the light source ports, so that the light sources generate a light superposition effect under the action of the different level signals. For example, the control module 300 can input low level signals to the red light source port 510 and the green light source port 520, while the blue light source port 530 remains high, at which time the red light source and the green light source are illuminated, thereby achieving the visual effect that the light emitting component 214 emits yellow light based on the principle of three primary colors. In other implementations, different voltage values (or pulse periods) of the level signal may also correspond to different brightnesses of the light sources, such that the light emitted by the light sources is mixed in different proportions and intensities.

It can be seen that the light emitting assembly 214 provides three primary color light sources and their respective connected light source ports, and the control module 300 can control the light emitting states of the light sources through the light source ports to achieve a diversified light combining effect.

In some embodiments of the present invention, the side of the light guide plate 211 may further be provided with a light shielding film. Specifically, the light shielding films may be disposed on four sides of the light guide plate 211, so as to prevent light leakage caused by light emitted from the sides of the light guide plate 211. The light shielding film may also be disposed in an area of the diffusion film 213 that is not shielded by the display module 220, so as to prevent the light from the front of the light guide plate 211 from affecting the viewing experience of the user on the display module 220.

In some embodiments of the present invention, the device further comprises a key switch module 900 and a lighting module 1000 disposed on the housing 100; the control module 300 is connected to the key switch module 900 and the lighting module 1000 to control the lighting module 1000 to be turned on according to the trigger state of the key switch module 900. In one implementation, as shown in fig. 7, 8 and 9, the key switch module 900 may be provided at a side of the housing 100, and the lighting module 1000 may be provided at another side of the housing 100.

That is, when the key assembly 910 is pressed, the control module can control the lighting module 1000 to be turned on, so as to perform the lighting function of the mobile power source.

In some embodiments of the present invention, as shown in fig. 7, 8 and 9, the lighting module 1000 may include a color-tunable lamp 1010, and the control module 300 is connected with the color-tunable lamp 1010 to control the color-tunable lamp 1010 to switch the light emitting color. The color-adjustable lamp 1010 may be a Cold Cathode Fluorescent Lamp (CCFL) or a Light Emitting Diode (LED) or other color-adjustable light sources, which is not limited in particular.

Specifically, the lighting module 1000 may further include a spotlight cover 1030 for covering the color-adjustable lamp 1010 and a transparent lens 1020 provided on the housing 100. Based on this, the lighting module may collect the light emitted from the color-adjustable lamp 1010 through the light-collecting lamp cover 1030, and then emit the collected light to the outside of the housing 100 through the transparent lens 1020.

In some embodiments of the present invention, the mobile power source further includes an input module 800, the input module 800 is used for receiving the trigger signal, and the control module 300 is connected to the input module 800 for controlling the color-tunable backlight module 210 to switch the backlight color according to the trigger signal.
