[0003] Among them, head-mounted AR glasses are more widely used. AR glasses generally provide two sets of imaging screens. In order to ensure the visual effect, it is generally necessary to adjust the positions of the two sets of imaging screens to ensure that the two sets of imaging screens received by the human eye can be integrated into one picture to avoid problems such as visual fatigue and dizziness.

[0026] To solve the problems in the prior art that the binocular fusion method of AR glasses has poor compatibility, the fusion effect is difficult to meet the actual needs of various users, and it is not conducive to the industrial expansion of AR glasses, this utility model provides an AR glasses drive module, which can realize the picture offset of the display in a numerical control manner and control the offset amount through an externally connected offset control keyboard, facilitating users to adjust the fusion effect according to the actual visual experience, thereby improving the final binocular fusion effect of the AR glasses and enhancing the user's visual experience.

[0027] Specifically, as Figure 1 and Figure 2 shown, the AR glasses drive module of this embodiment includes a main board 10, on which a data input interface 111, a power input interface 112, a power module 130, a conversion module 120, two display interfaces 113, a picture offset processing module 140, and an offset control keyboard interface 114 are provided.

[0028] Among them, the data input interface 111 is communicatively connected to the two display interfaces 113 through the conversion module 120 to convert the data protocol type accessed by the data input interface 111 into the data protocol type of the display. For example, in this embodiment, the data input interface 111 is implemented by a type-c total input interface 110, and the conversion module 120 is used to convert type-c protocol data into MIPI protocol data. In a specific example, the conversion module 120 can be implemented by a type-c to MIPI chip of model LT7911D.

[0029] Among them, the total input interface 110 can also select the corresponding interface type according to the actual interface configuration of the display screen, such as other USB interfaces such as type-A and type-B, and other integrated interfaces that can integrate power supply and data communication.

[0030] The offset control keyboard interface 114 is communicatively connected to the screen offset processing module 140. The screen offset processing module 140 is communicatively connected to two display interfaces 113. When a key trigger signal is received at the offset control keyboard interface 114, the screen offset processing module 140 can generate a pixel offset signal with corresponding offset information according to the number of triggers of the key trigger signal, and send the pixel offset signal to the corresponding display through the display interface 113, so that the display can adjust the position of the displayed screen according to the pixel offset signal.

[0031] The power supply module 130 is connected to the power input interface 112 and the power supply input terminals of other modules with power supply requirements to provide power supplies of various specifications for the effective operation of each module.

[0032] The data input interface 111 and the power input interface 112 are both implemented by a type-c total input interface 110. The total input interface 110 is arranged at one end of the main board 10. The offset control keyboard interface 114 is arranged at the other end of the main board 10. The screen offset processing module 140 is arranged in the middle area of the main board 10. The conversion module 120 is arranged between the screen offset processing module 140 and the total input interface 110, which is convenient for the layout of the wiring.

[0033] As a matching implementation, in this embodiment, an offset control keyboard 20 is further included. The offset control keyboard 20 includes two groups of four-way direction keys. The offset control keyboard 20 is communicatively connected to the offset control keyboard interface 114 through a Dupont wire for hot plugging, which is convenient for removing the offset control keyboard 20 after adjusting the binocular fusion effect.

[0034] The two groups of four-way direction keyboards respectively control the offset of the displayed screens of the two displays, and can achieve four-way offset in the up, down, left, and right directions. For example, in a specific example, a display of the Micro-OLED SY0.49WDM01 model is selected, and the offset configuration of its displayed screen is: with the center of the display screen as the origin, it can be moved 12 steps vertically upward and vertically downward, each step corresponding to an offset of 2 pixel points, and each step of offset can move the whole screen by 11.2 micrometers; it can be moved 16 steps horizontally to the left and horizontally to the right, each step corresponding to an offset of 1.5 pixel points, and each step of offset can move the whole screen by 8.4 micrometers. Overall, the displayed screen of a single display can be offset and adjusted within a range of 268.8 micrometers vertically and 268.8 micrometers horizontally.

[0035] Configuring two groups of four-way direction keyboards enables the offset of the displayed screens of the two displays to be adjusted separately, which can cope with the physiological deviation of the user's binocular vision, flexibly adjust according to the specific visual effect, and at the same time, the interpupillary distance of the two groups of displayed screens can be adjusted within a certain range, further improving the visual experience and reducing visual fatigue.

[0036] According to the data processing requirements, in a specific example, the single-chip microcomputer included in the screen offset processing module 140 generates a pixel offset signal with corresponding offset information according to the number of trigger signals of the accessed button trigger through the single-chip microcomputer. For example, it can be an STM8 type single-chip microcomputer, which can meet the data requirements. Among them, the screen offset processing module 140 is also communicatively connected to the data input interface 111 through the conversion module 120 to access the response to external regulation information through the data input interface 111, reducing the requirements for the communication interface for its program burning and control.

[0037] To ensure the power consumption requirements of each module, in this embodiment, the power supply module 130 includes a display driver unit, a low-dropout linear voltage regulator unit, and a switching voltage regulator unit, providing multi-specification voltage supplies.

[0038] Among them, the output end of the display driver unit is connected to two display interfaces 113, providing a regulated output of ±5.5V, which can be used as the high-level bias voltage and low-level bias voltage supplies for the display; the first voltage source output end of the low-dropout linear voltage regulator unit is connected to the first power supply input end of the conversion module, providing a 3.3V DC regulated output, which can be used as the chip power supply in the conversion module 120; the second voltage source output end and the third voltage source output end of the switching voltage regulator unit are respectively connected to the second power supply input end of the conversion module 120 and the power supply input end of the screen offset processing module 140, and the second voltage source output end and the third voltage source output end respectively provide 1.2V and 1.8V DC regulated outputs, which can be respectively used as the standard bias voltage for the logic signal in the conversion module 120 and the standard bias voltage for the logic signal in the screen offset processing module 140.

[0039] Among them, the switching voltage regulator unit provides two specifications of DC voltage outputs. For the convenience of implementation, in this embodiment, it is provided with a dual-output switching voltage regulator chip, and the two output ends of the dual-output switching voltage regulator chip are respectively connected to the second voltage source output end and the third voltage source output end of the switching voltage regulator unit, which can improve the circuit design integration degree of the main board and improve the efficiency.

[0040] In a specific example, the display driver unit, the low-dropout linear voltage regulator unit, and the switching voltage regulator unit can be respectively implemented by using power supply chips of models LT3471EDD, AMS1117-3.3, and MP2122GJ.

[0041] The conversion module 120 is mainly used for data conversion of the display screen information and has high requirements for signal accuracy. To ensure the reliability of the conversion, in this embodiment, a decoupling capacitor 101 is further provided on the main board 10. One end of the decoupling capacitor is respectively connected to the first voltage source output terminal of the low-dropout linear voltage regulation unit and the second voltage source output terminal of the switching voltage regulation unit, and the other end of the decoupling capacitor is grounded, which can improve the voltage stability of the 3.3V first voltage and the 1.2V second voltage supplied to the conversion module 120.

[0042] To improve the audio-visual effect, in this embodiment, an audio unit is further provided on the main board 10. The audio unit is communicatively connected to the data input interface 111 through the conversion module 120, and can simultaneously provide audio support to improve the AR effect.
