[0038] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0039] Example 1

[0040] This embodiment discloses a liquid crystal molecule arrangement system compatible with straight lines and curves, including:

[0041] A first driver for driving the horizontal translation stage to move in the X-axis direction.

[0042] A second driver is used to drive the horizontal translation stage to move in the Y-axis direction.

[0043] A third driver is used for driving the horizontal translation stage to rotate.

[0044] A fourth driver is used for adjusting the distance between the objective lens and the substrate in the Z-axis direction; the substrate is carried on the horizontal displacement stage, and the objective lens is arranged on the vertical displacement stage.

[0045] Acousto-optic crystal used to control optical path switches.

[0046] An electro-optical crystal used to control the phase change of a light beam.

[0047] A main controller that establishes communication connections with a host computer and the first driver, the second driver, the third driver, the fourth driver, the acousto-optic crystal and the electro-optic crystal respectively.

[0048] The main controller includes a memory A, a processor A, and a computer program stored in the memory A and executable on the processor A, such as Figure 1 As shown, the processor A executes the computer program to implement the following steps:

[0049] Step S1, determining the task mode set by the user via the host computer, wherein the task mode at least includes: a straight line mode and a curve mode; the types of curves include a circle and a vortex line.

[0050] Step S2: After obtaining the configuration information corresponding to the current task mode, execute the linkage control corresponding to the current task mode.

[0051] Among them, in the straight line mode, the optical path is maintained in an open state through the acousto-optic crystal and linked with the first driver until a single straight line is burned. In the process of the acousto-optic crystal switching to the off state, it is linked with the second driver to realize the interval straight line switching process.

[0052] In the curve mode, the acousto-optic crystal controls the switching state of the acousto-optic crystal according to the in-place pulse signal of the third driver, and cooperates with the first driver or the second driver to realize the switching of the phase interval circle or the gradual change of the distance between each orientation point on the vortex line and the center of the circle.

[0053] Furthermore, the system of this embodiment also includes a rotating table that can control the linear change of the light intensity incident on the substrate in a rotating manner, and a fifth driver for driving the rotating table to position the rotation angle, and the fifth driver establishes a communication connection with the main controller; the main controller is also used to maintain the light intensity output by the rotating table unchanged in the straight line mode; in the curve mode, the rotating table is controlled to make a linear incremental change with the distance between the current orientation point and the center of the circle. For example: a lower light intensity is used for processing the center of the circle, and a higher light intensity is used for processing the periphery of the circle, and the lower light intensity to the higher light intensity changes linearly with the processing radius. On the contrary, if the light intensity used in the center of the circle is high, there will be a risk of repeated erasure, and if the light intensity used in the periphery of the circle is low, there will be a risk of insufficient orientation dose. Thereby, the production yield and overall performance of the product can be improved.

[0054] Preferably, the electro-optical crystal is used to control the phase change of the light beam according to the received voltage, so that the polarization state of the output light beam can be different when the voltage received by the electro-optical crystal is different.

[0055] Preferably, the signals of the acousto-optic crystal and the electro-optic crystal come from a square wave controller linked to the main controller, and the square wave controller includes a memory B, a processor B, and a computer program stored in the memory B and executable on the processor, such as Figure 2 As shown, the processor B implements the following steps when executing the computer program:

[0056] Step B1, obtaining a trigger mode set by a user, the trigger mode including a first trigger mode and a second trigger mode, wherein the first trigger mode is triggered by a host computer signal, and the second trigger mode is triggered by an external signal.

[0057] Step B2, according to the current trigger mode, convert the trigger signal into a digital output signal, and convert the digital voltage signal transmitted by the host computer into an analog output signal; wherein the digital output signal is used to perform switching control of the optical path for the liquid crystal molecule orientation light beam, and the analog output signal is used to perform phase control of the light beam.

[0058] Among them, the voltage switching frequency corresponding to the first trigger mode is less than the voltage switching frequency corresponding to the second trigger mode; the external signal is an in-place signal for detecting the displacement control of the substrate to which the liquid crystal molecules belong based on the third driver; and in the second trigger mode, before the analog output signal is output, a delayed waiting process is performed on the digital output signal that has completed the conversion in advance.

[0059] Optionally, the above-mentioned delayed waiting processing can be implemented by processor B in cooperation with the electronically controlled switch, that is, after the rising edge of the pulse signal used for each trigger arrives, the digital output signal is first switched to a low level to cut off the optical path, and the digital output signal is switched back to a high level at the same time while waiting for the analog output signal to be converted and output; in the specific application scenario of the applicant in this case, the delay waiting time is generally less than or equal to 20 microseconds.

[0060] Preferably, the first trigger mode is matched with the straight line mode, and is used to orient the liquid crystal molecules on the substrate in the form of spaced parallel straight line tracks, and a single straight line corresponds to a continuous same voltage signal. At the same time, the second trigger mode is matched with the curve mode, and is used to orient the liquid crystal molecules on the substrate in the form of a curve track, and during the orientation process, the angles formed by the front and rear orientation points on the running track and the center of the circle are the same fixed value.

[0061] Typically, in the second trigger mode, the corresponding orientation points are respectively distributed on the spaced circles or the gradually changing vortex lines. Based on the fact that the second trigger mode corresponds to high-frequency voltage switching, the controller can support it with double buffering technology. To this end, preferably, in the second trigger mode, when the controller reads the voltage signal data packet from the host computer into the first cache, the discrete voltage signals between the orientation points in the first-read voltage data packet in the second cache are converted into corresponding analog output signals one by one according to the external trigger signal.

[0062] Furthermore, when the first trigger mode is applied to the linear orientation scenario, a redundant area can be extended outside the actual orientation area of ​​the substrate, and no liquid crystal is deployed in the redundant area; preferably, the redundant area can be directly a blank area of ​​the substrate displacement stage; and then the timing relationship between the analog output signal and the digital output signal can be calculated based on the physical parameters of the redundant area, so that the substrate can complete the switching between the spaced straight lines and the timing alignment between the analog output signal and the digital output signal before it moves to the actual orientation area; that is, the timing alignment between the two output signals is achieved in advance in the aforementioned redundant area. At the same time, by setting the redundant area, it can be ensured that the edge of the orientation area is reliably oriented, thereby further improving the overall performance.

[0063] In a specific application scenario, the system used to generate and focus the laser beam to achieve writing on the substrate includes a laser, an acousto-optic crystal, an electro-optic crystal, an objective lens, a shaping square hole, a lens, etc. Its motion control part includes:

[0064] During the operation of the system, the debugging work before writing to the substrate includes:

[0065] Step S00: The horizontal translation stage carries the substrate and moves it to the bottom of the distance measuring sensor. The writing height of different substrates and the center point of the substrate are found through the values ​​fed back by the distance measuring sensor. The center point is also the center of the circle during the rotation orientation process.

[0066] In the straight line writing process corresponding to the first trigger mode, the following steps are specifically included:

[0067] Step S11, the horizontal translation stage moves to the starting point of the scribe line mode, the rotation stage is adjusted so that the light intensity of the orientation light spot meets the requirements, and the square wave controller starts the first trigger mode.

[0068] Step S12, the host computer (the host computer refers to the host computer corresponding to the square wave controller, and the subsequent "host computer" in this embodiment continues the same concept and is not elaborated on; preferably, the host computer can be integrated with the host computer corresponding to the main controller on the same physical computer device to reduce costs) sends the voltage value (±5V) corresponding to the writing of n lines to the square wave controller, and sends a start instruction, the X-axis moves the processing width W, and completes the writing of n lines.

[0069] Step S13: The host computer sends a light-off instruction, and the Y axis moves in the positive direction by a distance of the light spot size D.

[0070] Step S14, the host computer sends the voltage value (±5V) corresponding to the writing of n+1 line to the square wave controller, and sends a light-on instruction, and the X-axis moves the processing width -W to complete the writing of n+1 line.

[0071] Step S15: The host computer sends a light-off instruction, and the Y axis moves in the positive direction by a distance of the light spot size D.

[0072] Step S16, repeat the above steps until the writing is completed.

[0073] In the straight line writing process corresponding to the second trigger mode, the following steps are specifically included:

[0074] Step S21: The horizontal translation stage moves to the starting point of the circle engraving mode, and the square wave controller starts the second trigger mode.

[0075] Step S22, the host computer sends the first two groups (16 lines, each line has 360 voltage data, one group: 8*360=2880 voltage data) of written voltage values ​​to the square wave controller.

[0076] Step S23, after the rotation axis enabled by the third driver reaches a speed of 8 revolutions per second, the PEG output signal is turned on (the signal is set as: 360 signals per circle, and the angle formed by two adjacent orientation points and the center of the circle is 1 degree). The PEG output signal is a rotation angle in-place pulse signal.

[0077] Step S24: To make the production efficiency of the product close to that corresponding to the above-mentioned linear mode, the Y-axis or X-axis runs at a speed of the spot size D*8 per second, and the driving rotary table changes linearly and incrementally synchronously with the distance between the current orientation point and the center of the circle.

[0078] Step S25: When the square wave controller receives the PEG pulse signal, it triggers the corresponding output voltage value of the electro-optical and acousto-optical ports. After triggering a set of data, the square wave controller requests the host computer to send the next set of data. At the receiving end, the voltage received by the electro-optical crystal is different, and the polarization state of the output light beam is also different.

[0079] Step S26: When the host computer sends all phase data or reaches a fixed size radius, the circular engraving is completed.

[0080] Thus, the linear engraving mode adopts a "bow" motion trajectory, and the circular engraving mode adopts a PEG uninterrupted method, which greatly improves production efficiency.

[0084] Step S2: After acquiring the configuration information corresponding to the current task mode, the main controller executes the linkage control corresponding to the current task mode.

[0085] Among them, in the straight line mode, the optical path is maintained in an open state through the acousto-optic crystal and linked with the first driver until a single straight line is burned. In the process of the acousto-optic crystal switching to the off state, it is linked with the second driver to realize the interval straight line switching process.

[0086] In the curve mode, the acousto-optic crystal controls the switching state of the acousto-optic crystal according to the in-place pulse signal of the third driver, and cooperates with the first driver or the second driver to realize the switching of the phase interval circle or the gradual change of the distance between each orientation point on the vortex line and the center of the circle; the third driver is used to drive the horizontal translation stage to rotate, and the first driver and the second driver are used to drive the horizontal translation stage to move in the X-axis and Y-axis directions respectively.

Generally, conventional touch modes also include self-test and other modes, which are prior arts well known to those skilled in the art and will not be described in detail.
