Description

Technical Field

[0001] This invention belongs to the field of touch display technology, specifically relating to an eye-protecting, energy-saving touch display that is visible under sunlight and its manufacturing method. Background Technology

[0002] Currently, the mainstream displays on the market include fully transparent displays, reflective displays, semi-reflective and semi-transparent displays, and organic electro-laser displays, etc.

[0003] For fully transparent displays used outdoors in strong sunlight, the ambient light makes the backlight appear severely insufficient due to the intense sunlight. Simply increasing the backlight brightness to achieve visibility in sunlight would increase power consumption, rapidly deplete battery, and cause users to worry about battery life. This phenomenon also exists in organic-electro-optical laser displays.

[0004] Conventional reflective displays have no backlight, making them unsuitable for use in low light or no light conditions. Without a light source to reflect, the content on the display cannot be seen, limiting their applicability.

[0005] Semi-reflective and semi-transmissive displays have a lower reflectivity than fully reflective displays; their transmittance is also much lower. When there is insufficient external light, turning on the backlight will result in higher power consumption compared to fully reflective displays. The cost will also be higher.

[0006] E-ink screens have slow response times and low color gamuts, limiting their application range.

[0007] Making a touch screen eye-friendly, energy-efficient, and sunlight-visible presents many challenges in its production. These challenges include the numerous functional layers, requiring complex positioning and mounting, as well as frequent flipping operations, all of which result in high production costs.

It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0044] The following is combined with Figure 1-6 This invention describes a specific embodiment of a touch screen that is eye-friendly, energy-saving, and visible under sunlight, comprising the following steps:

[0045] S1. Obtain the state of the high-transparency optical light guide plate 44, and install the high-transparency optical light guide plate 44 on the touch screen manufacturing fixture; use a robotic arm in conjunction with a suction cup structure to transfer the high-transparency optical light guide plate 44 horizontally and place it vertically at the target position.

[0046] S2. Cover plate 42 and composite polarizer 46 are attached. Optical bonding layer 1 43 and optical bonding layer 2 45 are respectively attached to the two sides of the high-transmittance optical light guide plate 44. The composite polarizer 46 with integrated AR function can reduce reflectivity and increase the transmittance of ambient light; the cover plate 42 with AR anti-reflection function can improve the brightness of the display screen.

[0047] S3. Install a front light source 48 and a flexible circuit board 50 on one side of the high-transparency optical light guide plate 44 to obtain a front light source assembly; fix it with optical adhesive.

[0048] S4. Obtain the state of the lower glass panel 56 and install the lower glass panel 56 on the touch display manufacturing fixture; the principle is the same as in step S1; the lower glass panel 56 has transparent ITO lines on its surface. (If it is a TFT display, there are also TFT thin film transistors).

[0049] S5. A high-reflectivity layer 55, a liquid crystal layer 54, a transparent touch function sheet 53, and an upper glass panel 52 are sequentially attached to one side of the lower glass panel 56. The liquid crystal layer 54 is sealed between the upper and lower glass panels using Black Matrix, Seal, Short.

[0050] S6. An integrated chip 49 and a flexible circuit board 51 are installed on one side of the lower glass panel 56 to obtain a touch display module 47.

[0051] S7. The upper glass panel 52 of the touch display module 47 is attached to the composite polarizer 46, and a protective film 41 is attached to the side of the cover plate 42 away from the high-transmittance optical light guide plate 44 to obtain the eye-protecting, energy-saving, sunlight-visible touch display screen.

[0052] In steps S1 and S4, the touch display manufacturing fixture includes a support frame 11. A mounting base 14 is fixedly provided on one side of the support frame 11, and a drive motor 13 is detachably mounted on the mounting base 14. A rotating frame 12 is detachably mounted on the support frame 11, and a rotating shaft 21 is fixedly provided at one end of the rotating frame 12. The rotating shaft 21 is rotatably connected to the support frame 11 and fixedly connected to the output shaft of the drive motor 13. A rotating arm 30 is detachably mounted at each end of the rotating frame 12, and a rotating arm 30 is detachably mounted on each rotating arm 30. A telescopic tube 23 is provided, one end of which is connected to an air pump. A suction cup 15 is fixedly provided at the end of the telescopic tube 23 away from the air pump. The suction cup 15 is used to adsorb the board 16 and make it have a stable posture. The board 16 includes the high-transparency optical light guide plate 44 and the lower glass panel 56. When manufacturing a touch screen with many functional layers, it is necessary to frequently attach different functional layers. Moreover, the target board 16 is not only a processing area on one side. Therefore, it is also necessary to flip it. The rotating frame 12 can smoothly flip the board 16 after it is fixed by the suction cup 15.

[0053] Advantageously, a mounting groove 35 is provided on one side of the rotating frame 12, and a control motor 28 is fixedly installed in the mounting groove 35. A drive gear 27 is fixedly installed on the output shaft of the control motor 28, and a transmission gear 31 is provided on one side of the drive gear 27. The transmission gear 31 meshes with the drive gear 27, and the transmission gear 31 is fixedly mounted on a control shaft 32. The control shaft 32 is rotatably connected to the rotating frame 12. The control motor 28 controls the swing of the rotating arm 30 to ensure sufficient operating space when the plate 16 enters.

[0054] Advantageously, the rotating frame 12 has hollow internal structures at both ends. Each end of the control shaft 32 is connected to a main shaft via a one-way bearing 33. The main shafts are rotatably connected to the rotating frame 12 and are located within the hollow structure of the rotating frame 12. Two main shafts pass through both ends of the rotating frame 12, and each main shaft is rotatably connected to a rotating arm 30. The rotating arms 30 on both sides are controlled independently. The rotating arms 30 can simultaneously clamp the plate 16, or only the lower rotating arm 30 can provide support for the plate 30.

[0055] Advantageously, a limiting plate 36 is fixed at each end of the rotating frame 12, and the two limiting plates 36 are located on opposite sides of the rotating frame 12. The limiting plates 36 correspond to the opposite installation methods of the two one-way bearings, and the directions of transmission of the 12 on both sides are opposite. Therefore, when the control shaft 32 rotates, only one rotating arm 30 will rotate, and the other rotating arm 30 can be controlled by rotating the control shaft 32 in the opposite direction.

[0056] Advantageously, each of the rotating arms 30 is provided with a control cylinder 18, the cylinder barrel of which is fixedly connected to the rotating arm 30. A connecting plate 24 is fixedly provided on the piston rod of the rotating arm 30, and the connecting plate 24 is used to control the horizontal height of the suction cup 15. The control cylinder 18 can control the suction cup 15 to move closer to or further away from the plate 16.

[0057] Advantageously, each of the rotating arms 30 has a groove 29 on one side, within which a sliding rod 17 is slidably mounted. A guide plate 20 is fixedly mounted on the side of the sliding rod 17, and the guide plate 20 is slidably connected to the groove 29. A fixing sleeve 25 is fixedly mounted on one side of the sliding rod 17, and the fixing sleeve 25 is fixedly connected to the connecting plate 24. The rotating arm 30 is connected to the rotating frame 12 via a torsion spring. It is necessary to note that when the rotating arm is not subjected to external force, it always maintains its position under the action of the torsion spring. Figure 4 The state shown is such that the guide plate 20 restricts the sliding rod 17 from rotating, allowing it to move only axially.

[0058] Advantageously, an adjusting motor 26 is fixedly mounted on one end of the fixing sleeve 25 near the plate 16. The output shaft of the adjusting motor 26 passes through the fixing sleeve 25. A control gear is rotatably mounted inside the fixing sleeve 25, and the control gear is fixedly connected to the output shaft of the adjusting motor 26. Two adjusting rods 19 are slidably mounted inside the fixing sleeve 25, located on both sides of the control gear. The ends of the two adjusting rods 19 that are close to each other have teeth, and the teeth on the adjusting rods 19 mesh with the control gear. The openings on both sides of the fixing sleeve 25 are narrow, restricting the movement of the adjusting rods 19 to only along their length.

[0059] Advantageously, each of the two adjusting rods 19 on the same side is provided with a telescopic tube 23, and each telescopic tube 23 is provided with a buffer spring 22 on its periphery. The two ends of the buffer spring 22 abut against the suction cup 15 and the adjusting rod 19, respectively. When the suction cup 15 approaches the plate 16, the telescopic tube 23 and the buffer spring 22 with telescopic function will not damage the plate 16.

[0060] An eye-friendly, energy-saving, sunlight-visible touch display screen includes a front light source assembly and a touch display module 47 assembled together; the front light source assembly includes a cover plate 42, a high-transmittance optical light guide plate 44 and a composite polarizer 46 placed together in sequence; the touch display module 47 includes a lower glass panel 56, a high-reflection layer 55, a liquid crystal layer 54, a transparent touch function sheet 53 and an upper glass panel 52 placed together in sequence.

[0061] Advantageously, one end of the high-transparency optical light guide plate 44 is provided with a front light source 48 and a flexible circuit board 50; one end of the lower glass panel 56 is provided with an integrated chip 49 and a flexible circuit board 51.

[0062] Working principle of this invention:

[0063] The touch screen manufacturing fixture has a symmetrical structure with identical structures on both sides. The following description focuses on the structure of one side. In the initial state, the robotic arm controls the suction cup structure to grip the plate 16 and waits on one side of the touch screen manufacturing fixture. The rotating frame 12 is in a vertical state, and the two suction cups on the same side are close to each other.

[0064] When the control motor 28 starts, it controls its output shaft to rotate. The drive gear 27 rotates together with the control motor 28. The drive gear 27 drives the transmission gear 31 to rotate through meshing. The control shaft 32 rotates together with the transmission gear 31. The control shaft 32 attempts to drive the two main shafts to rotate through the one-way bearings 33 on both sides. However, the two one-way bearings 33 are installed in opposite directions, resulting in opposite directions of rotation restriction. At any given time, the control shaft 32 will only drive one main shaft to rotate, while the other main shaft will not rotate. By changing the rotation direction of the control shaft 32, the state of whether the two main shafts rotate can be changed.

[0065] Initially, the control motor 28 controls the rotation of the upper main shaft, which drives the upper rotating arm 30 to rotate. After the upper rotating arm 30 rotates 90 degrees, it contacts the upper limit plate 36 and cannot continue to rotate. At this time, the control motor 28 stops working and the output shaft is locked. In this state, the two suction cups 15 on the upper side are located on the side of the support frame 11, and the corresponding torsion springs remain compressed. When the mechanical arm controls the plate 16 to enter the designated position vertically, it is not affected by the path.

[0066] After the plate 16 reaches the set position, the lower adjustment motor 26 starts, controlling its output shaft to rotate, which drives the control gear to rotate. The control gear meshes and drives the two adjustment rods 19 to move away from each other, which in turn drives the two buffer springs 22 to move away from each other. The two buffer springs 22 move away from each other to the edge position of the corresponding plate 16. Then the lower control cylinder 18 starts, controlling its piston rod to extend, driving the connecting plate 24 to move closer to the plate 16. The connecting plate 24 drives the fixed sleeve 25 and the sliding rod 17 to move. The sliding rod 17 and the sliding groove 29 slide. The fixed sleeve 25 drives the two adjustment rods 19 and the two buffer springs 22 to move closer to the plate 16. The buffer springs 22 stop when they are close to the plate 16. The air pump starts to suck in air, controlling the two buffer springs 22 to hold the plate 16. At this time, the lower side of the plate 16 has stable support and load-bearing capacity.

[0067] When the plate 16 is the lower glass panel 56, ensure that it has a stable posture until the touch display module 47 is assembled; when the plate 16 is the high-transparency optical light guide plate 44, first attach the cover plate 42, flip the high-transparency optical light guide plate 44 and then attach the composite polarizer 46.

[0068] When flipping, the control motor 28 is in standby mode, its output shaft becomes free, the upper torsion spring loses external force constraint and resets, driving the upper rotating arm 30 to reset, so that the two upper suction cups 15 return from the side of the support frame 11 to the top of the plate 16; similar to the above principle, the adjustment motor 26, control cylinder 18 and air pump are started in sequence to make the upper suction cups 15 also adsorb the plate 16.

[0069] By starting the drive motor 13, the rotating frame 12 is flipped, which in turn causes the plate 16 to flip 180 degrees. Then, following the same principle, the suction cup 15, which was originally on the lower side, is flipped to the upper side, and after being deflated, it is moved to the side of the support frame 11, thereby ensuring sufficient operating space when processing the other side of the high-transparency optical light guide plate 44.

[0070] In addition, the touch screen manufacturing fixture can provide a stable posture for the board 16 during bonding and adhesion. It can also rotate at any angle while both suction cups 15 are attached to meet the needs of welding flexible circuit board 1 50 and flexible circuit board 2 51, as well as the needs of brushing ink around the lamp core of the front light source 48.

[0071] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0072] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined by the claims of the present invention, they should all fall within the protection scope of the present invention.
