Translated fromChinese技术领域technical field
本发明涉及智能设备领域，尤指一种多区域调光膜驱动电路、方法和可穿戴设备。The invention relates to the field of smart devices, in particular to a multi-region dimming film driving circuit, method and wearable device.
背景技术Background technique
调光膜为可调节光线通过状态的一种膜。它主要工作在散射态和透明态之间，也就是膜本身可在透明与非透明状态(视觉效果接近磨砂玻璃)之间变幻，透明度由电压调节。The dimming film is a film that can adjust the light passing state. It mainly works between the scattering state and the transparent state, that is, the film itself can change between the transparent and non-transparent state (the visual effect is close to frosted glass), and the transparency is adjusted by voltage.
调光膜包括PDLC和PNLC(Polymer Dispersed Liquid Crystal)反向智慧调光膜。PNLC(Polymer Network Liquid Crystal)即聚合物网络液晶的模式，与PDLC相比，PNLC中的液晶不是成球形(或椭球形)微滴，而是分布在聚合物三维网络中，形成连续性的通道网。The dimming film includes PDLC and PNLC (Polymer Dispersed Liquid Crystal) reverse smart dimming film. PNLC (Polymer Network Liquid Crystal) is the mode of polymer network liquid crystal. Compared with PDLC, the liquid crystal in PNLC is not spherical (or ellipsoidal) droplets, but distributed in the three-dimensional polymer network to form continuous channels. network.
PNLC还没有被广泛使用，因此没有直接使用的驱动芯片。在PNLC已知的应用领域里，很少需要细腻的灰阶变化，这些应用通常也不需要对显示区域作区域划分。PNLC is not yet widely used, so there is no direct-use driver chip. In the known application fields of PNLC, subtle grayscale changes are rarely required, and these applications usually do not require regional division of the display area.
尤其是以PNLC作为眼镜镜片，通常只需要在透明和变雾中切换。而对于如何准确的控制PDLC或PNLC作为眼镜镜片，实现渐变雾化及渐变透明，没有统一的解决方案。Especially with PNLC as spectacle lenses, it is usually only necessary to switch between clear and foggy. However, there is no unified solution for how to accurately control PDLC or PNLC as spectacle lenses to achieve gradient fogging and gradient transparency.

实施例一Example 1
本发明提供一种多区域调光膜驱动电路，包括：The present invention provides a multi-region dimming film driving circuit, comprising:
驱动模块，与调光膜模块连接，用于接收电压信号，通过所述驱动模块中运算放大器放大所述电压信号，使得所述调光膜模块的公共端和区域控制端形成不同的压差，以使所述调光膜模块渐变雾化或渐变透明；a driving module, connected to the dimming film module, for receiving a voltage signal, and amplifying the voltage signal through an operational amplifier in the driving module, so that the common terminal of the dimming film module and the regional control terminal form different voltage differences, To make the dimming film module gradually foggy or gradually transparent;
其中，所述调光膜模块包括PNLC模块或PDLC模块。Wherein, the dimming film module includes a PNLC module or a PDLC module.
优选的，所述驱动模块，包括：Preferably, the drive module includes:
第一驱动子电路，与所述公共端连接，用于接收第一电压信号以输出放大后的第一电压至所述公共端。The first driving sub-circuit is connected to the common terminal, and is used for receiving a first voltage signal to output the amplified first voltage to the common terminal.
第二驱动子电路，与所述区域控制端连接，用于接收第二电压信号以输出放大后的第二电压至对应的区域控制端，形成所述第一电压和所述第二电压的压差，以使所述调光膜模块渐变雾化。The second driving sub-circuit is connected to the regional control terminal, and is used for receiving the second voltage signal to output the amplified second voltage to the corresponding regional control terminal to form a voltage of the first voltage and the second voltage poor, so that the dimming film module is gradually fogged.
其中，调光膜模块是指液晶膜或电致发光材料，可以贴敷在普通玻璃、树脂镜片、以及PI等有机片材上。Among them, the dimming film module refers to a liquid crystal film or an electroluminescent material, which can be attached to ordinary glass, resin lenses, and organic sheets such as PI.
优选的，所述驱动子电路，包括：Preferably, the driving sub-circuit includes:
第一驱动子电路，与所述公共端连接，用于接收第三电压信号以输出第三电压至所述公共端。The first driving sub-circuit is connected to the common terminal, and is used for receiving a third voltage signal to output a third voltage to the common terminal.
第二驱动子电路，与所述区域控制端连接，用于接收第四电压信号以输出所述第四电压至对应的区域控制端，形成所述第三电压和所述第四电压的压差，以使所述调光膜模块渐变透明。The second driving sub-circuit is connected to the regional control terminal, and is used for receiving a fourth voltage signal to output the fourth voltage to the corresponding regional control terminal to form a voltage difference between the third voltage and the fourth voltage , so that the dimming film module is gradually transparent.
示例性的，如图1所示，参考PNLC的特性，其雾度随电压的升高而增加，因此，可以直接将目标雾度所对应的电压加在对应的区域，即可获得目标雾度。Exemplarily, as shown in Figure 1, referring to the characteristics of PNLC, its haze increases with the increase of voltage. Therefore, the target haze can be obtained by directly adding the voltage corresponding to the target haze to the corresponding area. .
在本方案中，将运算放大器用于放大电压，根据运算放大器的特性，使其差分输入端输入对应的电压，经过运算放大器放大后即可用于驱动PNLC镜片。In this scheme, the operational amplifier is used to amplify the voltage. According to the characteristics of the operational amplifier, the corresponding voltage is input to the differential input terminal, and after being amplified by the operational amplifier, it can be used to drive the PNLC mirror.
需要特别说明的是，当使用PDLC时，该电路依然有效，只是对应的逻辑相反，即雾度随电压的升高而降低，在实际的程序设计中，只需增加一个减法，将原目标电压减掉满幅电压，即可得到PDLC的控制电压。It should be noted that when using PDLC, the circuit is still valid, but the corresponding logic is reversed, that is, the haze decreases with the increase of voltage. Subtract the full-scale voltage to obtain the control voltage of the PDLC.
在PNLC的镜片中，分区即使用不同的运放输出，对该分区雾度控制所需的电压，以下为两个镜片，左、右各4个区，将4个区合在一起，完整的驱动逻辑如下：In the lens of PNLC, the partition uses different op amp outputs to control the voltage required for the haze control of the partition. The following are two lenses, 4 areas on the left and right, and the 4 areas are combined together, the complete The drive logic is as follows:
1.使用5个运放，分别对应OP1-5，镜片分4个区，对应一个公共端，4个区域端，分别与OP1-5相连。1.
2.在镜片透明状态下，各运放输出电压为0。2. In the transparent state of the lens, the output voltage of each op amp is 0.
3.按渐变逻辑，要求4个区域由外到内逐渐变化，即外转区域1变到20％时，区域2开始变化，区域2变化到20时，区域3开始变化，区域3变化到20％时，区域4开始变化，直到所有的区域都变为100％，建立电压和雾度的对应关系表，该表格可以在简单实施例中等效为线性表，比如20％雾度对应8V电压，100％雾度对应18V电压，即可以认为对应8-18V的范围是20％-100％的调节范围。3. According to the gradient logic, the 4 areas are required to gradually change from outside to inside, that is, when the
4.COM端作为公共端，为满足液晶必须加交流电压的要求，以100Hz在0V-18V间切换，当VCOM为0V时，对应的电压为V1-V4，当VCOM为18V时，对应的电压即为(18-V1)、(18-V2)、(18-V3)、(18-V4)。4. The COM terminal is used as the common terminal. In order to meet the requirement that the liquid crystal must be supplied with AC voltage, it switches between 0V-18V at 100Hz. When VCOM is 0V, the corresponding voltage is V1-V4, and when VCOM is 18V, the corresponding voltage That is (18-V1), (18-V2), (18-V3), (18-V4).
在本实施例中，可以得到驱动镜片的电压波形，以得到灰度的连续变化，使得镜片渐变雾化或渐变透明。In this embodiment, the voltage waveform for driving the lens can be obtained, so as to obtain a continuous change of gray scale, so that the lens is gradually foggy or transparent.
通过本发明，可有效地对用于镜片的PNLC或PDLC进行区域控制，通过PWM调制驱动镜片用的100Hz低频电压，将电压经过放大器加到镜片上。因为PWM可以线性调制驱动波形，可以准确地给出驱动电压和时序，可以很好的满足对镜片分区域的大范围的雾度控制。Through the present invention, the PNLC or PDLC used for the lens can be effectively controlled in the area, the 100Hz low frequency voltage used for driving the lens can be modulated by PWM, and the voltage can be applied to the lens through the amplifier. Because PWM can linearly modulate the driving waveform, the driving voltage and timing can be accurately given, and the haze control of a wide range of lens sub-regions can be well satisfied.

When the haze of the peripheral area is the preset haze, the area adjacent to the peripheral area and close to the central area starts to be haze. Exemplarily, as shown in Figure 2, two sets of DC voltages are amplified by two high-voltage operational amplifiers, and the output is:
令VREF＝0.5V，并按如图2所示的电阻值，得到下表：Let VREF = 0.5V, and according to the resistance values shown in Figure 2, the following table is obtained:
在本实施例中，运算放大器可以是芯片内部已经存在的运算放大器，示例性的，如图2所示的芯片(U11)，其型号为OPA2991SRUG，假设此芯片只包括两个运算放大器，用于控制两个区域控制端，一个运算放大器的同相输入端通过电阻(RR32)与电压输入端(VIN3)连接，运算放大器的反相输入端通过电阻(RR33)与参考电压端(VREF)连接，运算放大器的反相输入端还通过电阻(RR33)与区域控制端(L_V1)连接。另一个运算放大器的的同相输入端通过电阻(RR34)与电压输入端(VIN4)连接，运算放大器的反相输入端通过电阻(RR35)与参考电压端(VREF)连接，运算放大器的反相输入端还通过电阻(RR31)与区域控制端(L_V2)连接。由于运算放大器需要供电，此芯片的电源输入引脚还连接有21V电源。本方案中，使用了单电源，将电池电压通过BOOST电路升至高压，比如25V，即可提供运行该电压进行驱动工作，但是在合理的运用中，也可以为运行提供正负电源，芯片的供电会稍有变换，但是基本拓朴不变。In this embodiment, the operational amplifier may be an operational amplifier that already exists inside the chip, for example, the chip (U11) shown in FIG. 2, whose model is OPA2991SRUG, assuming that the chip only includes two operational amplifiers for Control two regional control terminals, the non-inverting input terminal of an operational amplifier is connected to the voltage input terminal (VIN3) through a resistor (RR32), and the inverting input terminal of the operational amplifier is connected to the reference voltage terminal (VREF) through a resistor (RR33). The inverting input terminal of the amplifier is also connected to the regional control terminal (L_V1) through a resistor (RR33). The non-inverting input terminal of the other operational amplifier is connected to the voltage input terminal (VIN4) through a resistor (RR34), the inverting input terminal of the operational amplifier is connected to the reference voltage terminal (VREF) through a resistor (RR35), and the inverting input terminal of the operational amplifier is connected. The terminal is also connected to the regional control terminal (L_V2) through a resistor (RR31). Since the operational amplifier needs to be powered, the power input pin of this chip is also connected to a 21V power supply. In this scheme, a single power supply is used, and the battery voltage is raised to a high voltage through the BOOST circuit, such as 25V, which can provide the operating voltage for driving work, but in a reasonable application, it can also provide positive and negative power supplies for the operation. The power supply will change slightly, but the basic topology will remain the same.
在本实施例中，当区域控制端的电压与公开端的电压形成压差后，区域控制端会雾化，如图3所示表示驱动PNLC的波形，包括COM端和区域控制端：In this embodiment, when the voltage of the regional control terminal and the voltage of the public terminal form a voltage difference, the regional control terminal will be atomized, as shown in Figure 3, which shows the waveform of driving the PNLC, including the COM terminal and the regional control terminal:
在图3中，COM以100Hz，在0-20V间翻转，而LV1、LV2则控制电压，使与COM间的压差在控制范围内逐渐变大，从而对应的区域逐渐变雾。LV2按相对于LV1一定时间时延进行变化，得到其对应区域在LV1对应区域变化后跟随变化的效果。In Figure 3, COM flips between 0-20V at 100Hz, while LV1 and LV2 control the voltage, so that the voltage difference between COM and COM gradually increases within the control range, so that the corresponding area gradually becomes foggy. LV2 changes according to a certain time delay relative to LV1, and obtains the effect that its corresponding area follows the change after the corresponding area of LV1 changes.
以上每一个电压均与一个PWM值对应，但是通常将雾度变换调整成近似曲线。所以需要建立PWM点空比变换到雾度的对应表，本发明的应用例为，将PWM与驱动镜片的电压以线性对应，而随时间变化的PWM值与时间成近似对数关系，即镜片的起始会变化更缓慢，给人眼适当的适应时间。Each of the above voltages corresponds to a PWM value, but the haze transformation is usually adjusted to approximate the curve. Therefore, it is necessary to establish a corresponding table of PWM point-to-air ratio conversion to haze. The application example of the present invention is to linearly correspond PWM to the voltage of the driving lens, and the PWM value that changes with time has an approximate logarithmic relationship with time, that is, the lens The onset of the change will be slower, giving the human eye appropriate time to adapt.

虽然现有技术中存在利用雾化技术的提醒方式，用户距离过近时候就会直接瞬时雾化，影响用户体验。这种方式虽然带有强而直观的效果，然而直接的雾化和清晰会令用户睫状肌频繁短瞬调节，反而会加重视觉疲劳，另一方面，由于该设计会频繁打断用户视野，降低用户作业效率，同样会令用户心生厌恶。Although there is a reminder method using the atomization technology in the prior art, when the user is too close, it will be directly and instantly atomized, which affects the user experience. Although this method has a strong and intuitive effect, the direct atomization and clarity will cause the user to adjust the ciliary muscle frequently and instantaneously, which will aggravate visual fatigue. Reducing the user's work efficiency will also disgust the user.
在本实施例中，是通过分区雾化或缓慢雾化进行雾化操作，分区雾化或缓慢雾化有一个相对持续的过程，这持续的过程中给予了用户改正的契机，一旦用户调整到合适距离或矫正了正确坐姿，能够及时变成透明可视的状态，反应更快，更便捷。In this embodiment, the atomization operation is performed by partition atomization or slow atomization, and the partition atomization or slow atomization has a relatively continuous process, which gives the user an opportunity to correct. Once the user adjusts to the The right distance or correct sitting posture can be turned into a transparent and visible state in time, and the response is faster and more convenient.
在本实施例中，通过多区域调光膜驱动电路进行的多区域调光膜驱动方法，进行分区缓慢雾化和分区直接雾化具体包括以下步骤：In this embodiment, the multi-area light-adjustable film driving method performed by the multi-area light-adjustable film driving circuit, the sub-area slow atomization and the sub-area direct atomization specifically include the following steps:
当用户距离屏幕过近时，多区域调光膜驱动电路驱动调光膜模块的外围区域开始雾化，当外围区域的雾化值达到雾化阈值时，与外围区域相邻的区域开始雾化，直至中心区域雾化完成。When the user is too close to the screen, the multi-region dimming film drive circuit drives the peripheral area of the dimming film module to start atomization. When the atomization value of the peripheral area reaches the atomization threshold, the area adjacent to the peripheral area starts to be atomized , until the atomization of the central area is completed.

当用户视近的时候，左右镜片的最外围分区1，会率先逐渐变雾，经过t秒逐渐达到雾度的最大峰值Hmax。同时2分区在一定的时间差Δt后，逐渐变雾，达到Hmax。依次类推，直到n分区达到Hmax，镜片全部变雾，用户视野变模糊，达到强制提醒效果，在此过程中，用户如果恢复正常距离后，则雾化解除，镜片雾度由Hmax逐渐恢复至Hmin。其中，不同分区Δt与t根据实际体验确定，可以不一致。When the user is near vision, the
当用户歪头的时候，对应的歪头侧镜片以同样的逻辑变雾，而另外一边保持不变。在此过程中，用户恢复正常坐姿，雾化解除，镜片雾度由Hmax恢复至Hmin。When the user tilts his head, the corresponding lens on the tilted side becomes foggy with the same logic, while the other side remains unchanged. During this process, the user resumes the normal sitting posture, the fogging is released, and the haze of the lens is restored from Hmax to Hmin.
具体地：按分区渐变逻辑，要求4个区域由外到内逐渐变化，即外转区域1变到20％时，区域2开始变化，区域2变化到20时，区域3开始变化，区域3变化到20％时，区域4开始变化，直到所有的区域都变为100％。建立电压和雾度的对应关系表，该表格可以在简单实施例中等效为线性表，比如20％雾度对应8V电压，100％雾度对应18V电压，即可以认为对应8-18V的范围是20％-100％的调节范围。Specifically: According to the partition gradient logic, the four areas are required to change gradually from the outside to the inside, that is, when the

During this process, the user resumes the normal sitting posture, the fogging is released, and the haze of the lens is restored from Hmax to Hmin.
具体地：按直接渐变逻辑，要求4个区域同时同步变透明，根据建立的电压和雾度的对应关系表，按变化率，即：要求在N秒内镜片变透明，计算每个变化周期所需要的雾度，从关系表检索到电压，进而计算对应的PWM值，实现镜片的直接渐变，并且当N为零时，表示直接解除雾化。Specifically: According to the direct gradient logic, four areas are required to become transparent at the same time. According to the established corresponding relationship table between voltage and haze, according to the change rate, that is, the lens is required to become transparent within N seconds, calculate the amount of each change cycle. For the required haze, the voltage is retrieved from the relation table, and then the corresponding PWM value is calculated to realize the direct gradient of the lens, and when N is zero, it means that the haze is directly released.
分区雾化闪烁，该类型的设计逻辑与实现方式：Partition fogging and flickering, the design logic and implementation of this type:
利用反向PNLC技术，将镜片分至图示的n个分区，分区数量≥2。优选：2分区。分区表示由内到外可表示为1、2.....n-1、n。且眼镜左右各一片，承对称状，该镜片能实现在普通状态下透明，雾度表示为Hmin，通电状态下变雾,峰值雾度表示为Hmax，时间表示为t。Using the reverse PNLC technology, the lens is divided into n partitions as shown in the figure, and the number of partitions is greater than or equal to 2. Preferred: 2 divisions. The partition representation can be represented as 1, 2...n-1, n from the inside to the outside. And the glasses are one piece on the left and right, and symmetrical, the lens can be transparent in the normal state, the haze is expressed as Hmin, and it becomes foggy under the power-on state, the peak haze is expressed as Hmax, and the time is expressed as t.

当用户歪头的时候，对应的歪头侧镜片以同样的逻辑变雾，而另外一边保持不变。在此过程中，用户恢复正常坐姿，雾化解除。When the user tilts his head, the corresponding lens on the tilted side becomes foggy with the same logic, while the other side remains unchanged. During this process, the user returns to a normal sitting position and the atomization is released.
分区雾化呼吸，该类型的设计逻辑与实现方式：Partitioned atomization breathing, the design logic and implementation of this type:
利用反向PNLC技术，将镜片分至图示的n个分区，分区数量≥2，优选：2分区。分区表示由内到外可表示为1、2.....n-1、n。且眼镜左右各一片，承对称状，该镜片能实现在普通状态下透明，雾度表示为Hmin，通电状态下变雾,峰值雾度表示为Hmax，时间表示为t。Using the reverse PNLC technology, the lens is divided into n partitions as shown in the figure, and the number of partitions is greater than or equal to 2, preferably: 2 partitions. The partition representation can be represented as 1, 2...n-1, n from the inside to the outside. And the glasses are one piece on the left and right, and symmetrical, the lens can be transparent in the normal state, the haze is expressed as Hmin, and it becomes foggy under the power-on state, the peak haze is expressed as Hmax, and the time is expressed as t.
当用户视近的时候，左右镜片的外围分区1，会由逐渐变雾与逐渐分区中往复，呈呼吸状即(Hmin→Hmax→Hmin→Hmax)之间连续往复变化，进行用户提醒，如果t秒后用户依然没有改正，外圈分区保持雾化停止呼吸，内圈逐渐变雾，经过Δt秒后，达到峰值雾度Hmax。用户视野模糊，达到强制提醒效果，在此过程中，用户回复正常距离后，雾化解除,镜片雾度由Hmax恢复至Hmin。When the user is near-sighted, the
当用户歪头的时候，对应的歪头侧镜片以同样的逻辑变雾，而另外一边保持不变。在此过程中，用户恢复正常坐姿，雾化解除。When the user tilts his head, the corresponding lens on the tilted side becomes foggy with the same logic, while the other side remains unchanged. During this process, the user returns to a normal sitting position and the atomization is released.
在本实施例中，可以通过该方法根据实际情况实现四种不同的雾化方式，以供选择和调整，增加了该方法的灵活性和准确性。具体的，在PNLC的镜片中，分区即使用不同的运放输出对该分区雾度控制所需的电压，以下为两个镜片，左、右各4个区，将4个区合在一起，完整的驱动逻辑如下：In this embodiment, four different atomization modes can be realized by this method according to the actual situation for selection and adjustment, which increases the flexibility and accuracy of the method. Specifically, in the lens of PNLC, the partition uses different op amps to output the voltage required for haze control of the partition. The following are two lenses, 4 areas on the left and right, and the 4 areas are combined together, The complete drive logic is as follows:
1.使用5个运放，分别对应OP1-5，镜片分4个区，对应一个公共端，4个区域端，分别与OP1-5相连。1.
2.在镜片透明状态下，各运放输出电压为0。2. In the transparent state of the lens, the output voltage of each op amp is 0.
3.按渐变逻辑，要求4个区域由外到内逐渐变化，即外转区域1变到20％时，区域2开始变化，区域2变化到20时，区域3开始变化，区域3变化到20％时，区域4开始变化，直到所有的区域都变为100％。建立电压和雾度的对应关系表，该表格可以在简单实施例中等效为线性表，比如20％雾度对应8V电压，100％雾度对应18V电压，即可以认为对应8-18V的范围是20％-100％的调节范围。3. According to the gradient logic, the 4 areas are required to gradually change from outside to inside, that is, when the
4.COM端作为公共端，为满足液晶必须加交流电压的要求，以100Hz在0V-18V间切换，当VCOM为0V时，对应的电压为V1-V4，当VCOM为18V时，对应的电压即为(18-V1)、(18-V2)、(18-V3)、(18-V4)。4. The COM terminal is used as the common terminal. In order to meet the requirement that the liquid crystal must be supplied with AC voltage, it switches between 0V-18V at 100Hz. When VCOM is 0V, the corresponding voltage is V1-V4, and when VCOM is 18V, the corresponding voltage That is (18-V1), (18-V2), (18-V3), (18-V4).
在本实施例中，参考PNLC的特性，其雾度随电压的升高而增加，因此，可以直接将目标雾度所对应的电压加在对应的区域，即可获得目标雾度。In this embodiment, referring to the characteristics of PNLC, its haze increases as the voltage increases. Therefore, the target haze can be obtained by directly adding the voltage corresponding to the target haze to the corresponding region.
在本方案中，通过将运算放大器用于放大电压，根据运算放大器的特性，使其差分输入端输入对应的电压，经过运算放大器放大后即可用于驱动PNLC镜片。In this scheme, by using the operational amplifier to amplify the voltage, according to the characteristics of the operational amplifier, the differential input terminal of the operational amplifier inputs the corresponding voltage, which can be used to drive the PNLC mirror after being amplified by the operational amplifier.
需要特别说明的是，当使用PDLC时，该电路依然有效，只是对应的逻辑相反，即雾度随电压的升高而降低，在实际的程序设计中，只需增加一个减法，将原目标电压减掉满幅电压，即可得到PDLC的控制电压。It should be noted that when using PDLC, the circuit is still valid, but the corresponding logic is reversed, that is, the haze decreases with the increase of voltage. Subtract the full-scale voltage to obtain the control voltage of the PDLC.
