[0039] In order to better understand the technical content of the present invention, preferred specific embodiments are described below.

[0040] Please refer to the following Figures 1 to 5 An embodiment of the present invention provides a display system with a detachable light source. Figure 1 A schematic diagram of a display and a detachable light source panel separated from each other in a display system with a detachable light source according to an embodiment of the present invention.

[0041] like Figure 1 As shown, in one embodiment of the utility model, a display system 900 with a detachable light source can improve the display screen of a reflective display to provide a better visual experience. The display system 900 with a detachable light source includes a display 100 and a detachable light source panel 1. The display 100 is, for example, a reflective liquid crystal display or an electronic ink display. The size of the display 100 can be selectively adjusted to adapt to different application scenarios. The display 100 includes a display body 110, a display panel 120, a power supply module 130, a display power module 140, a slide groove 150, a slider 160 and a shielding plate 170.

[0042] In one embodiment of the present invention, the display body 110 is a flat housing of the display 100 for mounting various electronic components of the display 100. The display panel 120 is disposed on the display body 110 and is, for example, a reflective liquid crystal panel for displaying images for users to watch.

[0043] In one embodiment of the present invention, the power supply module 130 is disposed on the display body 110 and is located next to the display panel 120. The power supply module 130 includes two corresponding electrical connection points 131. The two corresponding electrical connection points 131 are, for example, metal conductive points, which are used to form an electrical connection with the detachable light source board 1, so that the display 100 transmits power to the detachable light source board 1 through the electrical connection. However, the number of the corresponding electrical connection points 131 is not limited to two, and it can be changed to any number of at least one according to design requirements.

[0044] like Figure 1 and Figure 5 As shown, in one embodiment of the utility model, the display power module 140 is, for example, a battery, which is disposed on the display body 110 and electrically connected to the display panel 120 and the power supply module 130, and is used to provide power to operate the display 100, and the power of the display power module 140 can be transmitted to the detachable light source panel 1 through the electrical connection formed by the power supply module 130 and the detachable light source panel 1.

[0045] like Figure 1 and Figure 4 As shown, in one embodiment of the present invention, the slide groove 150 is disposed on the side of the display body 110 and is located next to the power supply module 130. The slider 160 is located in the slide groove 150 and can slide in the slide groove 150. The shielding plate 170 is located next to the power supply module 130, and the shielding plate 170 is connected to the slider 160. When the slider 160 slides in the slide groove 150 along a sliding direction A, the slider 160 will drive the shielding plate 170 to move along the sliding direction A to cover the two corresponding electrical connection points 131; in this way, the shielding plate 170 can protect the two corresponding electrical connection points 131 from external dust and moisture, and avoid structural damage to the two corresponding electrical connection points 131. Alternatively, when the user wants to interrupt the electrical connection between the two corresponding electrical connection points 131 and the detachable light source panel 1, the shielding plate 170 can also be moved to cover the two corresponding electrical connection points 131 to interrupt the electrical connection.

[0046] like Figures 1 to 3 As shown, in one embodiment of the present invention, the detachable light source board 1 can be assembled with the display 100 and provide light to the display 100. The detachable light source board 1 includes a light guide plate 10, two light emitting modules 20, a power module 30 and a control chip 40.

[0047] In one embodiment of the present invention, the light guide plate 10 can be moved to cover the display panel 120 and is used to uniformly transmit light to the display panel 120. The two light-emitting modules 20 are both light-emitting strips provided with light-emitting diode lamps, which are respectively connected to the two sides of the light guide plate 10 and are used to irradiate a light toward the light guide plate 10; however, the number of the light-emitting modules 20 is not limited to two, and it can be changed to any number of at least one according to design requirements. Since the two light-emitting modules 20 emit light from the two sides of the light guide plate 10 toward the center of the light guide plate 10, it is possible to avoid excessive scattering of the front light source to places outside the range of the display 100. The configuration position of the front light source is not limited to the above, and it can be changed according to the use requirements, so it has scalability and can be applied to displays of various sizes and models.

[0048] The power module 30 is disposed on the light guide plate 10 and electrically connected to the two light emitting modules 20, and the position of the power module 30 corresponds to the power supply module 130. The power module 30 further includes two electrical connection points 31, and the two electrical connection points 31 are, for example, metal conductive points; when the light guide plate 10 covers the display panel 120, the two electrical connection points 31 respectively contact the two corresponding electrical connection points 131, thereby, an electrical connection is formed between the electrical connection points 31 and the corresponding electrical connection points 131, and the power of the display power module 140 can be transmitted to the power module 30 of the detachable light source panel 1 through the electrical connection formed by the power supply module 130 and the power module 30 of the detachable light source panel 1, and the power module 30 will transmit the received power to the two light emitting modules 20, so that the two light emitting modules 20 emit light.

[0049] like Figure 1 and Figure 5 As shown, in one embodiment of the present invention, the control chip 40 is, for example, a current control chip, which is disposed on the light guide plate 10 and electrically connected to the two light emitting modules 20 and the power module 30. The control chip 40 is used to control the current transmission and light of the detachable light source panel 1, for example, it can control the power transmission to the two light emitting modules 20 to dynamically adjust the light intensity.

[0050] like Figure 1 and Figure 2 As shown, when the user wants to use the display system 900 with a detachable light source, the detachable light source panel 1 can be first covered on the display 100, and the two electrical connection points 31 of the power module 30 are respectively in contact with the two corresponding electrical connection points 131 of the power supply module 130. When the light guide plate 10 covers the display panel 120, and the two electrical connection points 31 of the power module 30 are respectively in contact with the two corresponding electrical connection points 131 of the power supply module 130, the power module 30 and the power supply module 130 are electrically connected, so that the power module 30 receives power from the display power module 140 from the power supply module 130. After the power module 30 receives power from the display power module 140, the power module 30 transmits information about the received power to the control chip 40, and then the control chip 40 controls the power module 30 to transmit power to the two light-emitting modules 20. After receiving power, the two light-emitting modules 20 can irradiate a light toward the light guide plate 10. The light guide plate 10 that receives the light will evenly transmit the light to the display panel 120, so that the image displayed by the display panel 120 is clear and bright, providing a better visual experience. In addition, the uniform light guiding effect of the light guide plate 10 can improve the uniformity of the light and enhance the consistency of the display effect.

[0051] like Figure 1 and Figure 4As shown, if the user does not need to use the detachable light source panel 1, the user can also directly separate the detachable light source panel 1 from the display 100 and directly watch the image displayed by the display 100; and the user can operate the slider 160 to slide along the sliding direction A to drive the shielding plate 170 to move to cover the two corresponding electrical connection points 131 to protect the two corresponding electrical connection points 131 from external dust and moisture; or, the user can also keep the detachable light source panel 1 combined with the display 100, but operate the slider 160 to slide along the sliding direction A to drive the shielding plate 170 to move to cover the two corresponding electrical connection points 131 to interrupt the electrical connection between the power module 30 and the power supply module 130. The detachable design of the utility model allows the user to freely assemble the detachable light source panel 1 and the display 100 according to usage requirements, so that the detachable light source panel 1 will not continuously consume the power of the display 100, and the power consumption can be effectively managed, making the display 100 more energy-efficient; the detachable light source panel 1 can directly use the power of the display 100, so there is no need to plan an additional external power supply for the detachable light source panel 1.

[0052] Through the structural design of the display system 900 with a detachable light source of the utility model, light can be uniformly transmitted to the display panel, so that the picture displayed by the display panel is clear and bright, and a better visual experience is provided. Moreover, through the uniform light guiding effect of the light guide plate, the uniformity of light can be improved, thereby improving the consistency of the display effect. In addition, through the detachable design of the utility model, there is no need to directly fix the front light source on the display panel, so no fixed structure is generated, so it can avoid interfering with light reflection, reducing reflection and scattering effects, etc., which will cause low reflectivity, thereby improving the reflectivity of the reflective display; according to actual experimental tests, the reflectivity of the display system 900 with a detachable light source of the utility model is at least 5%, so it can improve the light and actually enhance the visual effect.

[0053] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
