Furthermore, in some situations, it is not suitable to actively increase ambient brightness, so lights cannot be used.

[0051] Example 1

[0052] Figure 1 This is a schematic diagram of a dimming glasses according to Embodiment 1 of the present invention. The dimming glasses include: a transparent LED display screen 22, mounted on a frame; a brightness sensor 21, superimposed on the transparent LED display screen 22; and a processor 3, connected to the transparent LED display screen 22 and the brightness sensor 21, and further configured to confirm the first brightness value sensed by the first pixel of the brightness sensor 21, and control the second pixel of the transparent LED display screen 22 to perform supplementary lighting display according to the first brightness value, wherein the positions of the first pixel and the second pixel overlap.

[0053] Referring to the cross-sectional view of the brightness sensor and the transparent LED display screen in Figure 2(a), in this embodiment, the brightness sensor 21 is superimposed on the transparent LED display screen 22 to form the dimming glasses lens 2. The transparent LED display screen 22 is positioned on the side of the dimming glasses closer to the eyes when in use. During use, light first passes through the brightness sensor 21 and then through the transparent LED display screen 22 before entering the eyes. Also referring to Figure 2(b), the dimming glasses lens 2 is mounted on the frame 1. In this embodiment, there are two dimming glasses lenses 2, mounted on the frame 1 corresponding to the position of the eyes. In other embodiments, the dimming glasses may also consist of one dimming glasses lens and one temple; this is not a limitation.

[0054] Specifically, the brightness sensor 21 consists of several red, green, and blue photodiodes, with each first pixel including one red, green, and blue photodiode. The red, green, and blue photodiodes of the first pixel are used to detect red, green, and blue light brightness values, respectively. Specifically, confirming the first brightness value sensed by the first pixel of the brightness sensor 21 includes: confirming the red light brightness value sensed by the first pixel; and / or confirming the green light brightness value sensed by the first pixel; and / or confirming the blue light brightness value sensed by the first pixel. The transparent LED display screen 22 consists of several red, green, and blue light-emitting diodes, with each second pixel including one red, green, and blue light-emitting diode. The transparent LED display screen 22 also includes driving wires connected to multiple second pixels. The second pixels are connected to a driving module via the driving wires. The driving module receives the information to be supplemented with light and drives at least one second pixel to perform supplementary lighting display. The transparent LED display screen 22 and the brightness sensor 21 have the same resolution, and the positions of the first pixels of the brightness sensor 21 and the second pixels of the transparent LED display screen 22 overlap. For example, see the cross-sectional schematic diagram of the brightness sensor 21 and the transparent LED display 22. Figure 3 The first pixels A1, A2, A3, A4, A5, A6, A7, A8 and A9 of the brightness sensor 21 are sequentially overlapped with the second pixels B1, B2, B3, B4, B5, B6, B7, B8 and B9 of the transparent LED display screen 22.

[0055] In this embodiment, when light passes through the first pixel of the brightness sensor 21, the first pixel of the brightness sensor 21 detects a first brightness value of the light and sends the first brightness value to the processor as an electrical signal. The processor controls the second pixel of the transparent LED display to perform supplementary lighting display based on the first ambient brightness value, including: when the first brightness value is lower than a first preset brightness, controlling the second pixel of the transparent LED display to perform supplementary lighting display based on the first brightness value. Specifically, controlling the second pixel of the transparent LED display to perform supplementary lighting display based on the first brightness value includes: controlling the second pixel of the transparent LED display to perform supplementary lighting display based on the red light brightness value; and / or controlling the second pixel of the transparent LED display to perform supplementary lighting display based on the green light brightness value; and / or controlling the second pixel of the transparent LED display to perform supplementary lighting display based on the blue light brightness value. For example, see... Figure 3 The 22 second pixels B2 of the transparent LED display screen provide supplementary lighting based on the first brightness value sensed by the first pixel A2. When the first pixel A1 detects that the first brightness value is less than a first preset brightness, the second pixel B1 corresponding to the first pixel A1 provides supplementary lighting according to the first brightness value detected by the first pixel A1.

[0056] In other embodiments, the intensity of the supplementary light display can be adjusted according to the level of the first brightness value. For example, when the first brightness value is relatively low, the light intensity is weaker, and it is more difficult to see the object, so a higher supplementary light intensity is required; when the first brightness value is relatively high, the light intensity is relatively high, but if the supplementary light is excessive, it will damage the human eye, so the supplementary light intensity can be reduced.

[0057] This invention solves the problem of unclear vision in low light conditions by setting a brightness sensor on the frame to sense the ambient light brightness, and using a processor to determine whether supplemental lighting is needed. Then, supplemental lighting is provided through a transparent LED display screen superimposed on the lens, thereby improving the visibility of objects in low-light environments.

[0058] In alternative embodiments, see Figure 4 The dimming glasses also include:

[0059] A liquid crystal refractive index 23 is superimposed on the transparent LED display screen 22.

[0060] In this alternative embodiment, see Figure 5 The liquid crystal refractor 23 is located on the side of the dimming glasses closest to the wearer's eyeball and is transparent. The liquid crystal refractor 23 is used to refract and adjust the light emitted from the transparent LED display screen 22 to improve the clarity of the dimming glasses' illumination. Specifically, the refractive index of the liquid crystal in a single pixel can be adjusted by controlling the voltage of the liquid crystal refractor to improve the clarity of the dimming glasses' illumination.

[0061] The processor 3 is connected to the liquid crystal refractor 23 and is also used to control the fifth pixel of the liquid crystal refractor to adjust the supplementary light display according to the first brightness value, wherein the positions of the second pixel and the fifth pixel overlap.

[0062] In this alternative embodiment, the transparent LED display screen 22 and the liquid crystal refractor 23 have the same resolution, and the positions of the second pixel and the fifth pixel correspond one-to-one and overlap. When the second pixel of the transparent LED display screen 22 provides supplementary lighting, the corresponding fifth pixel will be activated simultaneously to improve the clarity of the supplementary lighting of the second pixel.

[0063] The technical solution of this alternative embodiment can improve the clarity of the transparent LED display screen 22 when performing supplementary lighting display by further adding a liquid crystal refractive index 23.

[0064] Example 2

[0065] Figure 6This is a schematic diagram of a dimming glasses provided in Embodiment 2 of the present invention. The dimming glasses in this embodiment further include, based on Embodiment 1: a liquid crystal light valve 24, superimposed between the transparent LED display screen 22 and the brightness sensor 21; the processor 3 is also connected to the liquid crystal light valve 24, and is also used to confirm the second brightness value sensed by the third pixel of the brightness sensor 21, and control the fourth pixel of the liquid crystal light valve 24 to perform noise reduction display according to the second brightness value, wherein the positions of the third pixel and the fourth pixel overlap.

[0066] In this embodiment, cross-sectional views of the brightness sensor, liquid crystal light valve, and transparent LED display screen are also included. Figure 7 The resolution of the liquid crystal light valve 24 is the same as that of the transparent LED display screen 22. The liquid crystal light valve 24 is located on the side away from the human eye when the dimming glasses are worn, and is transparent. During use, light passes sequentially through the brightness sensor 21, the liquid crystal light valve 24, and the transparent LED display screen 22, and finally enters the human eye.

[0067] In this embodiment, the brightness sensor 21 is composed of a plurality of red, green, and blue photodiodes, and each third pixel includes one red, one green, and one blue photodiode. The red, green, and blue photodiodes of the third pixel are used to detect the red light brightness value, the green light brightness value, and the blue light brightness value, respectively. Specifically, confirming the third brightness value sensed by the third pixel of the brightness sensor 21 includes: confirming the red light brightness value sensed by the third pixel; and / or confirming the green light brightness value sensed by the third pixel; and / or confirming the blue light brightness value sensed by the third pixel. For example, see the cross-sectional schematic diagram of the brightness sensor 21 and the liquid crystal light valve 24. Figure 8 The third pixels C1, C2, C3, C4, C5, C6, C7, C8 and C9 of the brightness sensor 21 overlap with the fourth pixels D1, D2, D3, D4, D5, D6, D7, D8 and D9 of the liquid crystal light valve 24 in a corresponding manner.

[0068] Specifically, a liquid crystal light valve achieves phase delay of light by controlling the refractive index of liquid crystal molecules through voltage. When the voltage across the liquid crystal is zero and the liquid crystal molecules are aligned parallel to the glass plate, the difference between the o-ray and e-ray refractive indices is greatest. As the voltage across the liquid crystal layer increases, the liquid crystal molecules begin to rotate, and the difference between the o-ray and e-ray refractive indices gradually decreases until they are almost equal. If the polarization direction of the incident light is consistent with the o-ray refractive index of the liquid crystal, the phase delay generated by the liquid crystal is independent of the applied voltage. This is because the o-ray refractive index of the liquid crystal does not change with voltage. If the polarization direction of the incident light is consistent with the e-ray refractive index of the liquid crystal, the phase delay generated by the liquid crystal will change with voltage. By adjusting the phase delay, the liquid crystal light valve can achieve dual filtering to reduce the damage to the eyes caused by strong light.

[0069] In this embodiment, when light passes through the third pixel of the brightness sensor 21, the third pixel of the brightness sensor 21 detects a second brightness value of the light and sends the second brightness value to the processor as an electrical signal. The processor's control of the fourth pixel of the liquid crystal light valve for noise reduction display based on the second brightness value includes: when the second brightness value is higher than a second preset brightness, controlling the fourth pixel of the liquid crystal light valve for noise reduction display based on the second brightness value. Specifically, controlling the fourth pixel of the liquid crystal light valve 24 for noise reduction display based on the second brightness value includes: controlling the fourth pixel of the liquid crystal light valve for noise reduction display based on the red light brightness value; and / or controlling the fourth pixel of the liquid crystal light valve for noise reduction display based on the green light brightness value; and / or controlling the fourth pixel of the liquid crystal light valve for noise reduction display based on the blue light brightness value. For example, see... Figure 8 The fourth pixels D2 of the liquid crystal light valve 24 perform noise reduction display based on the second brightness value sensed by the third pixel C2 of the brightness sensor 21. When the third pixel C1 detects that the second brightness value is less than the second preset brightness, the fourth pixel D1 corresponding to the third pixel C1 performs noise reduction display according to the second brightness value detected by the third pixel C1.

[0070] In other embodiments, the strength of the noise reduction display can be adjusted according to the level of the second brightness value. For example, when the second brightness value is relatively high, the light intensity is greater, and it is easier to damage the human eye, so a higher noise reduction intensity is required; when the second brightness value is relatively low, the light intensity is relatively low. Although it can still damage the human eye, excessive noise reduction will make it difficult for the user to see clearly, so the noise reduction intensity can be reduced. In other embodiments, before controlling the liquid crystal light valve to perform noise reduction, the processor also confirms whether the current noise-reducing pixel is the pixel corresponding to the target object in the environmental image. Noise reduction display can be performed only on the fourth pixel corresponding to the target object.

[0071] In this embodiment, by further configuring the liquid crystal light valve 24, the processor 3 analyzes whether the image needs noise reduction, and then performs noise reduction display through the liquid crystal light valve 24 to reduce the brightness of strong external light entering the human eye. This solves the problem of high-intensity bright light damaging the human eye in high-light conditions, protecting the human eye and improving the viewing experience. The technical solution of this embodiment can also simultaneously perform supplementary lighting and noise reduction on different pixels of the same environmental image, solving the visual fatigue caused by simultaneously performing supplementary lighting and noise reduction on all pixels, and improving the user's viewing comfort.

[0072] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
