[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0039] The disclosure below provides many different embodiments or examples for realizing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0040] Please refer to Figure 1-Figure 7 An embodiment of the present application provides a color filter substrate, including a base substrate 10 , a color filter film layer 20 and at least one indicator light 30 .

[0041] The base substrate 10 may be a glass substrate, a resin substrate, a sapphire substrate, etc., and is not specifically limited here.

[0042] The color filter layer 20 is disposed on the base substrate 10 . The color filter layer 20 includes a plurality of color resists 21 . Adjacent color resists 21 are spaced apart from each other, and at least one receiving area 101 is formed between adjacent color resists 21 .

[0043] At least one indicator light 30 is disposed on the base substrate 10, and the indicator light 30 is located within the accommodation area 101. By disposing the indicator light 30 between adjacent color resists 21 to form at least one accommodation area 101, this embodiment of the present application avoids mutual obstruction between the color resists 21 and the indicator light 30, thereby ensuring the normal function of the color resists 21 and the indicator light 30. In this embodiment of the present application, the indicator light 30 can remain off when the screen is displayed and remain on when the screen is black.

[0044] Specifically, the number of indicator lights 30 can be one or more. Taking the case where the number of indicator lights 30 is more than one as an example, the indicator lights 30 can be distributed in a ring shape on the color film substrate, or the indicator lights 30 can be distributed in a dot shape on the color film substrate. For example, the indicator lights 30 can be distributed in the upper left, upper right or middle position on the color film substrate. Compared with the existing indicator lights set at a fixed position below the display panel, the embodiment of the present application can adjust the position of the indicator lights 30 on the color film substrate by adjusting the position of the indicator lights 30, so that the position of the indicator lights 30 for large display panels can also be adjusted, which is conducive to improving the flexibility and diversification of the setting position of the indicator lights 30. In addition, when the external ambient light is too strong during the day and it is impossible to visually see whether the indicator lights are on, when the user approaches the display device to check the lighting status of the indicator lights, there is no need to bend down to check, so that the indicator lights 30 can play a prompting role.

[0045] Of course, the indicator lights 30 can also be distributed at the lower left or lower right positions of the color film substrate. The indicator lights 30 of the embodiment of the present application can be distributed in any pattern in the color film substrate, and no specific restrictions are made here.

[0046] The indicator lights 30 may include, for example, Micro LED lights, Mini LED lights, or LED lights, and the present embodiment does not impose any specific limitations thereon. In the present embodiment, the plurality of indicator lights 30 may all be configured to emit red light. Of course, in other display environments, the indicator lights 30 may also be configured to emit any color light, such as white light, blue light, or green light, depending on the display requirements.

[0047] The color filter substrate of the present embodiment disposes the indicator light 30 within the accommodation area 101 between adjacent color resists 21 in the color filter layer 20 of the color filter substrate. This allows the indicator light 30 within the color filter substrate to radiate outward to achieve a light-indicating function. This facilitates adjustment of the position of the indicator light 30 as needed, thereby increasing flexibility in the placement of the indicator light 30. Furthermore, disposing the indicator light 30 within the color filter substrate eliminates the need for external indicator lights or for placing indicator lights in non-display areas in display devices employing the color filter substrate, thereby facilitating the realization of narrow or borderless display devices.

[0048] In some embodiments, as Figure 3As shown, an opening 201 is formed on the color resist 21, and the opening 201 is located in the accommodating area 101. The indicator light 30 is located in the opening 201. The multiple color resists 21 include a red light resist 211, a green light resist 212, and a blue light resist 213, which are arranged in sequence. After light passes through the red, green, and blue color resists 21, it can be combined into light of different colors to achieve a color display effect. Among them, the opening 201 and the indicator light 30 can be set in a one-to-one correspondence. Specifically, when the number of the indicator light 30 is one, the number of the opening 201 can also be one, and the opening 201 can be opened on any one of the color resists 21: the red light resist 211, the green light resist 212, or the blue light resist 213. When there are multiple indicator lights 30, there are also multiple openings 201. Each indicator light 30 is arranged in an opening 201. At this time, the opening 201 can be opened on the color resist 21 of the same color, or formed on the color resist 21 of different colors. The embodiment of the present application does not impose specific restrictions on this.

[0049] In some embodiments, please refer to Figure 3 The opening 201 is formed on the green color resist 212. Since green light is stronger and brighter, by forming the opening 201 on the green color resist 212 and placing the indicator light 30 on the opening 201 of the green color resist 212, the indicator light 30 can be placed close to the green color resist 212. When the image is displayed, even if the indicator light 30 is on, the green light will cover the light of the indicator light 30, making the human eye unable to perceive the existence of the indicator light 30, which is beneficial to reducing the impact on the image quality of the display.

[0050] In some embodiments, the color filter substrate further includes a common electrode layer 40. The common electrode layer 40 is disposed on the color filter layer 20. Specifically, the common electrode layer 40 is disposed on the side of the color filter layer 20 facing away from the base substrate 10. The common electrode layer 40 can transmit a common voltage to the color filter substrate. The material of the common electrode layer 40 can be, but is not limited to, ITO (Indium Tin Oxide). The common electrode layer 40 can also be a transparent conductive film formed from one or more other transparent materials, such as indium gallium zinc oxide (IGZO) or indium zinc oxide (IZO).

[0051] The indicator light 30 has a connecting electrode 31, and the common electrode layer 40 includes a connecting trace 41, and the connecting electrode 31 is connected to the connecting trace 41. In the embodiment of the present application, the common electrode layer 40 is partially used to transmit a common voltage and partially used as the connecting trace 41 to connect the indicator light 30. Specifically, the connecting trace 41 can be formed by patterning the common electrode layer 40.

[0052] In some embodiments, the color filter layer 20 further includes a black matrix 22. The black matrix 22 is disposed between adjacent color resists 21, and the indicator light 30 is disposed on the black matrix 22. The black matrix 22 is used to prevent crosstalk between the colors emitted by the various color resists 21. The black matrix 22 can be arranged in a grid pattern. By disposing the indicator light 30 on the black matrix 22, the area of ​​each color resist 21 is avoided, which helps maintain the display aperture 201 ratio.

[0053] In some embodiments, as Figure 4 and Figure 5 As shown, a limiting hole 202 is provided on the black matrix 22, and the indicator light 30 is located in the limiting hole 202, and the indicator light 30 is located on the base substrate 10. Specifically, the indicator light 30 can be fixed in the limiting hole 202 by dispensing glue or welding. The connecting electrode 31 is exposed in the limiting hole 202, and the connecting electrode 31 is electrically connected to the common electrode layer 40 through the limiting hole 202. Specifically, the limiting hole 202 passes through the black matrix 22 along the thickness direction of the base substrate 10. By locating the indicator light 30 in the limiting hole 202 of the black matrix 22, it is possible to prevent the light of the indicator light 30 from causing crosstalk with the light emitted by the adjacent color resist 21. Furthermore, in the embodiment of the present application, light in the color film substrate is emitted along the color filter layer 20 toward the base substrate 10 . That is, the side of the base substrate 10 facing away from the color filter layer 20 is the light-emitting surface. Therefore, by positioning the indicator light 30 within the limiting hole 202 of the black matrix 22 , the indicator light 30 can be close to the light-emitting surface, so that the light of the indicator light 30 is emitted from the light-emitting surface, which is beneficial to improving the light-emitting efficiency of the indicator light 30 .

[0054] In some embodiments, the color filter substrate further includes a protective layer 50, which is disposed on the color filter layer 20. Specifically, the protective layer 50 is located on the side of the color filter layer 20 away from the base substrate 10. The protective layer 50 protects the color filter layer 20, ensuring that the filtering performance of the color filter layer 20 remains stable during long-term use, thereby improving display quality.

[0055] The connecting electrode 31 includes a first electrode 311 and a second electrode 312. Specifically, the first electrode 311 and the second electrode 312 can be the positive electrode and the negative electrode of the indicator light 30. Correspondingly, the connecting trace 41 includes a first trace 411 and a second trace 412. The first trace 411 is connected to the first electrode 311, and the second trace 412 is connected to the second electrode 312.

[0056] The common electrode layer 40 is disposed on the protective layer 50. Specifically, the common electrode layer 40 is disposed on the side of the protective layer 50 facing away from the base substrate 10. The common electrode layer 40 includes a first trace 411 and a second trace 412. The protective layer 50 is provided with a first hole 501 and a second hole 502. The first trace 411 in the common electrode layer 40 is connected to the first electrode 311 through the first hole 501, and the second trace 412 in the common electrode layer 40 is connected to the second electrode 312 through the second hole 502. By providing the first hole 501 and the second hole 502 in the protective layer 50, the common electrode layer 40 can be electrically connected to the indicator light 30 while also protecting the color filter layer 20.

[0057] In some embodiments, as Figure 6 As shown, the color filter substrate also includes a flexible circuit board 60 and a driving circuit board 70. One end of the flexible circuit board 60 is bound to one side of the common electrode layer 40 and is coupled to the indicator light 30 through the connecting trace 41. Specifically, the flexible circuit board 60 is coupled to the indicator light 30 through the first trace 411 and the second trace 412. The driving circuit board 70 is connected to the other end of the flexible circuit board 60. The flexible circuit board 60 is used to connect the indicator light 30 and the driving circuit board 70. The driving circuit board 70 is used to drive the indicator light 30 to emit light. When there are multiple indicator lights 30, the driving circuit board 70 can drive multiple indicator lights 30 to emit light at the same time, or it can drive any one of the indicator lights 30 to emit light. For example, when there are multiple indicator lights 30, the driving circuit board 70 controls any one of the indicator lights 30 to emit light. Specifically, as Figure 7 As shown, taking the number of indicator lights 30 as one as an example, the indicator light 30 includes a first light-emitting diode LED1, and the indicator light 30 circuit includes a first resistor R1, a first transistor Q1, a second resistor R2 and the first light-emitting diode LED1, the base of the first transistor Q1 is electrically connected to the first resistor R1, the collector of the first transistor Q1 is electrically connected to the power supply 3.3V, the emitter of the first transistor Q1 is electrically connected to the second resistor R2, the anode of the first light-emitting diode LED1 is electrically connected to the second resistor R2; the cathode of the first light-emitting diode LED1 is grounded.

[0058] Taking the example of two indicator lights 30, correspondingly, the indicator light 30 also includes a second light-emitting diode LED2, then the indicator light 30 circuit also includes a third resistor R3, a second transistor Q2, a fourth resistor R4 and a second light-emitting diode LED2, the base of the second transistor Q2 is electrically connected to the third resistor R3, the collector of the second transistor Q2 is electrically connected to the power supply 3.3V, the emitter of the second transistor Q2 is electrically connected to the fourth resistor R4, the anode of the second light-emitting diode LED2 is electrically connected to the second resistor R2; the cathodes of the first light-emitting diode LED1 and the second light-emitting diode LED2 are grounded in common.

[0059] The first transistor Q1 and the second transistor Q2 in the indicator light 30 circuit are both driven by the transistor BT3906. The indicator light 30 circuit can control the first light-emitting diode LED1 and the second light-emitting diode LED2 to emit the same color of light, or different colors of light. For example, the first light-emitting diode LED1 can emit red light, and the second light-emitting diode LED2 can emit green light. If a low level is applied to the L1 pin, the first transistor Q1 is turned on, the first light-emitting diode LED1 is energized, and emits red light; if a low level is applied to the L2 pin, the second transistor Q2 is turned on, and the green light is emitted. If a high level is applied to both pins, both transistors Q1 and Q2 are turned off, and neither LED1 nor LED2 emits light.

[0060] By providing multiple indicator lights 30 that emit different colors, users can customize the position of the indicator lights 30 on the screen. This improves the flexibility of positioning the indicator lights 30 and facilitates customization of the display device. Furthermore, the provision of multiple indicator lights 30 enhances the display effect of the indicator lights 30 and improves the aesthetics of the off-screen display. Furthermore, since the base substrate 10 on the color filter substrate has a large area, there is ample space for various shapes of the indicator lights 30, which enhances the aesthetics of the indicator lights 30. For example, the indicator lights 30 can be arranged in a clock pattern. In this case, the driver circuit board 70 can drive multiple indicator lights 30 to display the time during standby mode.

[0061] In order to better implement the color film substrate of the present application, the embodiment of the present application also provides a display panel, please refer to Figure 8 The display panel includes a first substrate 100 , a second substrate 200 and a liquid crystal layer 300 .

[0062] The first substrate 100 and the second substrate 200 are disposed opposite each other, and the second substrate 200 is the aforementioned color filter substrate. A liquid crystal layer 300 is disposed between the first substrate 100 and the second substrate 200. The display panel of the present embodiment disposes the indicator light 30 within the accommodation area 101 between adjacent color resists 21 in the color filter layer 20 of the color filter substrate. This allows the indicator light 30 within the color filter substrate to radiate outward to achieve a light-indicating function, thereby facilitating adjustment and change of the position of the indicator light 30 as needed, thereby increasing the flexibility of the placement of the indicator light 30. Furthermore, disposing the indicator light 30 within the color filter substrate eliminates the need for external indicator lights or for placement of indicator lights in non-display areas in display devices employing the color filter substrate, thereby facilitating the realization of a narrow or borderless display device. Since the display device incorporates the aforementioned display panel, it exhibits all the same beneficial effects, and this embodiment will not be further elaborated upon.

[0063] In order to better implement the display panel of the present application, the embodiment of the present application further provides a display device, which includes the display panel. Since the display device includes the display panel, it has all the same beneficial effects, and this embodiment will not be repeated here.

It can be a handheld device (smartphone, tablet computer, etc.), wearable device (smart bracelet, wireless headset, smart watch, smart glasses, etc.), vehicle-mounted device (navigation system, assisted reversing system, driving recorder, car refrigerator, etc.), virtual reality device, augmented reality device, terminal device (Terminal Device), etc., without any restriction here.
