Technical Field
[0001] The utility model relates to the technical field of LCD liquid crystal displays, and more specifically, to a multi-view adaptive brightness adjustment LCD module. Background Technique
[0002] A liquid crystal display (LCD) is a type of display used in digital clocks and many portable computers. LCD displays use two sheets of polarizing material with a liquid crystal solution between them. When an electric current passes through the liquid, the crystals rearrange so that light cannot pass through them. Thus, each crystal acts like a shutter, allowing light to pass through or blocking it. Liquid crystal displays (LCDs) are currently developing towards the goal of being light, thin, short, and small. Display products with a long history in computer peripherals are of course no exception. Under the premise of being easy to carry and transport, traditional display methods such as CRT cathode ray tube displays and LED display panels are restricted by factors such as excessive volume or high power consumption, and cannot meet the actual needs of users. The development of liquid crystal display technology just fits the current trend of information products. Whether it is the advantages of right-angle display, low power consumption, small size, or zero radiation, users can enjoy the best visual environment.
[0003] With the continuous development of LCD liquid crystal display technology, in order to meet people's needs, current LCDs all have the function of adaptive brightness adjustment. By adding a photosensitive component and a backlight source inside the LCD, the photosensitive component senses the light source intensity of the external environment, and then adjusts the light emission intensity of the backlight source to achieve the adaptive adjustment of the LCD brightness. Since most LCDs place the photosensitive component inside the LCD, only a small part of the light intensity can be sensed, and the external light intensity cannot be sensed omnidirectionally, resulting in an insufficiently obvious effect when the LCD adaptively adjusts the brightness. Therefore, we propose a multi-view adaptive brightness adjustment LCD module. Summary of the Utility Model

A light sensing component is placed on the support plate. The rear end of the light sensing component is fixedly connected with a wire rod. The other end of the wire rod is fixedly connected with a backlight source. The backlight source is located inside the LCD body.

[0024] A liquid crystal display (LCD) is a type of display used in digital clocks and many portable computers. LCD displays use two pieces of polarizing material with a liquid crystal solution between them. When an electric current passes through the liquid, it causes the crystals to realign so that light cannot pass through them. Thus, each crystal acts like a shutter, allowing light to pass through or blocking it. Liquid crystal displays (LCDs) Currently, technological information products are all developing towards the goals of being light, thin, short, and small. Of course, display products with a long history in computer peripherals are no exception. Under the premise of being easy to carry and transport, traditional display methods such as CRT cathode ray tube displays and LED display panels, etc., are all restricted by factors such as being too large in volume or consuming a large amount of power, and cannot meet the actual needs of users. The development of liquid crystal display technology just fits the current trend of information products. Whether it is the advantages of right-angle display, low power consumption, small size, or zero radiation, etc., it can allow users to enjoy the best visual environment. Please refer to Figures 1-6 As shown, the present utility model provides a multi-view adaptive brightness adjustment LCD module, including a housing 1. A motor 2 is fixedly connected to the inner surface of the bottom of the housing 1. The top end of the motor 2 is rotationally connected to a push rod 24 and a ring 3. The right end of the push rod 24 is slidably connected to a push block 25. The front end of the push block 25 is fixedly connected to a sliding housing 27. A plurality of square grooves 33 are formed in the side surface of the ring 3. A light collecting tube 31 is fixedly connected in the square groove 33. A support block 11 is fixedly connected to the front end of the bottom of the housing 1. The top end of the support block 11 is fixedly connected to a support plate 12. A light sensing component 15 is placed on the support plate 12. A wire rod 13 is fixedly connected to the rear end of the light sensing component 15. The other end of the wire rod 13 is fixedly connected to a backlight 16. The backlight 16 is located inside the LCD body 14.
[0025] The improvement of the present utility model lies in:
[0026] Since most LCDs place the light sensing component 15 inside the LCD, it can only sense a small part of the light intensity and cannot sense the external light intensity in all directions, resulting in an insufficiently obvious effect when the LCD adaptively adjusts the brightness. The motor 2 works, thereby pushing the upper push rod 24 to move to the right, pushing the push block 25 to move backward along the inclined plane, driving the sliding housing 27 to slide into the housing 1, the bevel gear three 32 rotates, driving the ring 3 to rotate, thereby driving a plurality of light collecting tubes 31 to perform a circular motion, collecting and detecting the light intensity of the external environment in all directions. While the sliding housing 27 shrinks, the light collecting tubes 31 perform a circular motion, thus ensuring the normal operation of the light collecting tubes 31. The detected light intensity is transmitted to the light sensing component 15, and the light sensing component 15 adjusts the light emitting intensity of the backlight 16, better realizing the brightness adaptive adjustment of the LCD.
[0027] In order to make it easier for the pushing block 25 to drive the contraction of the sliding shell 27, the left end of the push rod 24 and the right end of the pushing block 25 both adopt an "inclined plane" structure. The inclined plane position of the push rod 24 corresponds to the inclined plane position of the pushing block 25. Since the pushing block 25 is close to the right inner wall of the outer shell 1, when the push rod 24 pushes the pushing block 25 along the inclined plane, the pushing block 25 is forced to move backward, thereby driving the contraction of the sliding shell 27.
[0028] Considering that the pushing block 25 can automatically return to the initial position after driving the contraction of the sliding shell 27, a spring 26 is fixedly connected to the rear end of the pushing block 25, and the other end of the spring 26 is fixedly connected to the inner surface of the outer shell 1. When the pushing block 25 contracts, it squeezes the spring 26. When the pressure on the pushing block 25 is removed, under the action of the elastic force of the spring 26, the pushing block 25 and the sliding shell 27 return to the initial position.
[0029] In order to better collect and detect the external light intensity, the light collecting tube 31 is of an "L" - shaped structure. The front end of the light collecting tube 31 is a "trapezoidal" open - end. A reflecting plate 34 is fixedly connected at the internal turning point of the light collecting tube 31. The included angle between the reflecting plate 34 and the inner wall of the light collecting tube 31 is 45 degrees. The light is reflected by the reflecting plate 34 inside the light collecting tube 31 and reaches the photosensitive component 15 from the outside, thereby ensuring that the photosensitive component 15 can more accurately sense the external light intensity and can better adjust the light - emitting intensity of the backlight 16.
[0030] In order to better limit the up - and - down movement of the push rod 24, a clamping plate 17 is fixedly connected to the rear - end inner wall of the outer shell 1. The clamping plate 17 is slidably connected to the push rod 24 and is located on the upper and lower sides of the push rod 24, ensuring that the push rod 24 only moves in the horizontal direction, so as to better push the pushing block 25.
[0031] In order to better control the movement of the push rod 24 and the rotation of the ring 3, a first bevel gear 21 is fixedly connected to the top of the motor 2. Above the first bevel gear 21, a second bevel gear 22 and a third bevel gear 32 are meshed. A fourth gear 23 is fixedly connected to the rear end of the second bevel gear 22. The push rod 24 is rotatably connected above the fourth gear 23. A ring 3 is fixedly connected to the front end of the third bevel gear 32. When the motor 2 works, it drives the first bevel gear 21 to rotate, thereby driving the second bevel gear 22 and the third bevel gear 32 to rotate simultaneously. The second bevel gear 22 drives the rear - end fourth gear 23 to rotate, thereby pushing the upper push rod 24 to move to the right. The third bevel gear 32 rotates, driving the ring 3 to rotate, so as to ensure that when the sliding shell 27 contracts, the light collecting tube 31 also rotates.
[0032] In summary, the working principle of this solution is as follows:
[0033] When using this device, the motor 2 operates to drive the first helical gear 21 to rotate, thereby driving the second helical gear 22 and the third helical gear 32 to rotate simultaneously. The second helical gear 22 drives the fourth rear gear 23 to rotate, thereby pushing the upper push rod 24 to move rightward, pushing the push block 25 to move backward along the inclined plane, driving the sliding shell 27 to slide into the interior of the outer shell 1, realizing the contraction of the sliding shell 27. At the same time, the third helical gear 32 rotates to drive the ring 3 to rotate, thereby driving a plurality of light collecting tubes 31 to perform circular motion, realizing the collection and detection of the light intensity of the external environment in multiple directions. The light in the external environment is reflected by the reflector 34 in the light collecting tube 31 and reaches the photosensitive component 15 from the outside, thereby ensuring that the photosensitive component 15 can more accurately sense the external light intensity and can better adjust the light emitting intensity of the backlight 16. Since the backlight 16 extends into the LCD body 14, it is ensured that the brightness of the LCD is only related to the light emitting intensity of the backlight 16. Therefore, when the photosensitive component 15 adjusts the light emitting intensity of the backlight 16, the adaptive adjustment of the LCD brightness is realized.
