Description

Technical Field

[0001] This invention relates to the field of integrated circuit technology, and in particular to an electro-electro ... Background Technology

[0002] Electroluminescent devices, broadly speaking, refer to devices whose physical or chemical properties undergo reversible changes under the influence of an electric field. In practical applications, these electroluminescent devices include electroluminescent (EL) elements and electrochromic elements, which have attracted considerable attention due to their enormous application potential in cutting-edge fields such as flexible displays, smart wearables, energy-efficient buildings, and information displays. However, efficient, stable, and controllable driving technology for electroluminescent devices has remained a key bottleneck for their industrialization.

[0003] Taking electroluminescent elements as an example, electroluminescence is a phenomenon that directly converts electrical energy into light energy. Based on this principle, electroluminescent elements, as a novel type of light-emitting device, have attracted much attention due to their unique light-emitting mechanism. In practical applications, electroluminescent elements can have flexible forms such as wire-like shapes. Due to their soft, thin, and lightweight characteristics, they are very suitable for application areas with high requirements for device flexibility and form adaptability, such as decoration, clothing, wearable devices, and smart tags. At the same time, electroluminescent elements can also have diverse product forms such as screens and EL panels, demonstrating wide applicability.

[0004] In practical applications, a high-voltage AC voltage with a fixed frequency and phase is typically applied across the electroluminescent element. The strong electric field generated by the high-voltage AC voltage excites the luminescent material (such as phosphor) inside the electroluminescent element to emit light, thereby enabling the device to emit light. However, the widespread adoption of such electroluminescent elements, which require high-voltage AC driving, has been severely hampered by bottlenecks in driving power supply technology.

[0005] The traditional and mainstream driving scheme uses power frequency or high frequency transformers (such as electromagnetic transformers) to boost AC voltage. Specifically, low-voltage DC or low-frequency AC power first passes through an inverter circuit, then is boosted and isolated by a transformer to finally obtain the high-voltage AC signal required to drive the electroluminescent element. This transformer-based driving architecture has several fundamental drawbacks that are difficult to overcome: First, transformers (especially those that need to process high-voltage, high-frequency signals) are physically large and heavy, and are closely related to magnetic materials, making integration extremely difficult in modern electronic devices that pursue miniaturization and thinness, severely limiting the freedom of end-product design. Second, the output characteristics of the transformer are determined by its electromagnetic structure, and the adjustment of parameters such as voltage, frequency, and waveform of the output signal is not flexible enough, making it difficult to achieve fine and dynamic brightness and effect control. The control method of the output signal is relatively simple and complex. For example, to adjust the brightness of the electroluminescent element, the frequency of the AC voltage is usually increased, which places higher demands on other configuration circuits such as frequency conversion circuits. Furthermore, transformer-based systems usually require a large number of external discrete components, resulting in a large overall driving circuit with high power consumption, limited efficiency, and high cost. These factors collectively make it difficult to miniaturize, integrate, and reduce the cost of driving devices for electroluminescent elements, thus greatly hindering the widespread commercialization and large-scale application of electroluminescent elements in the aforementioned broad application fields. Therefore, improvements to the driving devices for electroluminescent elements are necessary.

[0064] As mentioned above, the difficulty in integrating and miniaturizing transformers, as well as the single control method for transformer output signals, has prevented the widespread adoption of electro-electronic devices. For example, in existing methods, adjusting the brightness or color of an electro-electronic device mainly relies on increasing the frequency of the AC voltage provided by the transformer. This places high demands on the transformer, requiring additional circuitry to ensure adjustment capability. However, this method undoubtedly significantly increases the complexity of the electro-electronic device's driving mechanism.

[0065] To address the aforementioned problems, this invention provides a method based on clock phase difference. Controlled electro-electro-driven adjustment device (see also) Figure 1 The drive adjustment device generates two low-voltage clock signals through a clock phase modulation circuit I100, and then converts these two low-voltage clock signals into two high-voltage drive signals through two clock level conversion drive circuits, which are then applied to the two electrodes of the electro-electrode. In practical applications, the phase difference between the two low-voltage clock signals can be adjusted. This invention achieves adjustment of the effective value (RMS) of the AC voltage difference between the two electrodes of an electro-electrolyte, thereby regulating the brightness or color of the electro-electrolyte. As described above, the drive adjustment device of this invention can achieve drive and feature regulation of the electro-electrolyte based on low-voltage logic signal control, efficiently generating high-voltage alternating signals without the need for a transformer. This device achieves this by controlling the phase difference between two clock signals. The method of regulating the electro-electro ...

[0066] Example 1

[0067] like Figure 1 As shown, this invention provides a method based on clock phase difference. A controllable driving and regulating device for an electroluminescent element, wherein the electroluminescent element is an electroluminescent element I130. The device includes a clock phase modulation circuit I100, a first clock level conversion driving circuit I110, and a second clock level conversion driving circuit I120. The clock phase modulation circuit I100 generates a low-voltage first clock signal CLKA and a low-voltage second clock signal CLKB. The input terminal of the first clock level conversion driving circuit I110 is connected to the output terminal of the clock phase modulation circuit I100, and its output terminal is connected to the first electrode of the electroluminescent element I130. The first clock level conversion driving circuit I110 receives the first clock signal CLKA and amplifies it to convert it into a first driving level DRVA, the phase of which is the same as the phase of the first clock signal CLKA. The input terminal of the second clock level conversion driving circuit I120 is connected to the output terminal of the clock phase modulation circuit I100, and its output terminal is connected to the second electrode of the electroluminescent element I130. The second clock level conversion driving circuit I120 is used to receive the second clock signal CLKB and amplify it to convert it into a second driving level DRVB. The phase of the second driving level DRVB is the same as the phase of the second clock signal CLKB.

[0068] In practical applications, the first clock level conversion driving circuit I110 and the second clock level conversion driving circuit I120 apply a first driving level DRVA and a second driving level DRVB to the two electrodes of the same electroluminescent element I130, respectively, to form an AC voltage across the electroluminescent element I130. Under a given driving level amplitude, the clock phase modulation circuit I100 can adjust the phase difference between the first clock signal CLKA and the second clock signal CLKB. The waveform of the AC voltage formed by the superposition of the first driving level DRVA and the second driving level DRVB across the electroluminescent element I130 is adjusted, thereby adjusting the effective value RMS of the AC voltage without changing their respective amplitudes, thus achieving the adjustment of the brightness of the electroluminescent element I130.

[0069] As described above, the driving adjustment device of this invention completely eliminates the need for large transformers and other equipment required by traditional electroluminescent driving. Through a clock phase modulation circuit I100 combined with a clock level conversion driving circuit, it directly utilizes a low-voltage logic clock signal as the control center, amplifying the low-voltage logic clock signal to generate the two high-voltage driving levels required to drive the electroluminescent element I130. This "low-voltage logic control + high-voltage level conversion" approach completely avoids the use of transformers / magnetic components, enabling the entire driving adjustment device to achieve high miniaturization, lightweight design, and chip-level integration, clearing obstacles for the application of the electroluminescent element I130 in space-constrained fields such as wearable devices and flexible electronics. Furthermore, this driving adjustment device achieves an extremely simple and efficient brightness adjustment mechanism, so that the brightness control of the electroluminescent element I130 no longer relies on complex peripheral circuits or direct adjustment of the driving signal frequency; it only adjusts the phase difference between the two basic clock signals. This allows for flexible adjustment of the brightness of the I130 electroluminescent element. This single-variable control strategy not only has a simple circuit structure (no additional voltage or frequency modulation modules are required), but also features a simple and efficient adjustment method, fast adjustment response speed, high precision, and high adjustment flexibility.

[0070] Furthermore, this invention simplifies the complex AC voltage RMS control to a single core variable: the phase difference. With precise adjustment, brightness control does not require complex voltage, frequency, or duty cycle adjustment circuits. It only requires a clock modulation module that can precisely control the phase, which greatly simplifies the complexity of control algorithms and circuit design.

[0071] like Figure 1 As shown, in this embodiment, the clock phase modulation circuit I100 is used to generate a first clock signal CLKA and a second clock signal CLKB. The driving adjustment device includes a first clock level conversion driving circuit I110 and a second clock level conversion driving circuit I120 to perform level conversion on the first clock signal CLKA and the second clock signal CLKB respectively, so as to realize the light emission driving and brightness control of a single electroluminescent element I130, or the synchronous light emission driving and brightness control of at least two electroluminescent elements I130.

[0072] In practical applications, this invention does not limit the frequency range, duty cycle, or other factors of the first clock signal CLKA and the second clock signal CLKB; they may or may not be exactly the same. Preferably, in this embodiment, the first clock signal CLKA and the second clock signal CLKB have the same frequency and duty cycle. Based on this approach, the influence of the AC drive voltage applied to the electroluminescent element I130 can be reduced, which helps to simplify the complex multivariate brightness control mechanism into a precise and continuous single variable (phase difference). The control mechanism is simple. Furthermore, this method eliminates the need for additional adjustment of the signal's duty cycle, amplitude, or frequency, resulting in a simple circuit structure and straightforward, efficient control logic. It also reduces the functional requirements of the clock phase modulation circuit I100, simplifying the overall circuit design and control logic. On the other hand, when the driving adjustment device is used to drive and regulate multiple electroluminescent elements I130 (e.g., a fiber optic array), the first clock signal CLKA and the second clock signal CLKB, operating at the same frequency and duty cycle, ensure that all electroluminescent elements I130 operate at the exact same driving frequency. This eliminates uneven brightness and visual flicker caused by slight differences in driving frequency among different electroluminescent elements I130, guaranteeing high uniformity and consistency of light emission from a large-scale array. Similarly, the first driving level DRVA and the second driving level DRVB also have the same frequency and duty cycle.

[0073] Furthermore, in this embodiment, when the first clock signal CLKA and the second clock signal CLKB are in a high-level state, their voltage values ​​are the same, both being the first preset voltage VCC. When the first clock signal CLKA and the second clock signal CLKB are in a low-level state, both are at the reference ground potential. Figure 2 As shown, when the first driving level DRVA and the second driving level DRVB are in a high-level state, their voltage values ​​are the same, both being the second preset voltage VPP; when the first driving level DRVA and the second driving level DRVB are in a low-level state, both are reference ground potentials.

[0074] Based on the above, the circuit design requirements for the clock phase modulation circuit I100, the first clock level conversion drive circuit I110, and the second clock level conversion drive circuit I120 are greatly reduced, which helps to reduce the complexity of the entire drive adjustment device. At the same time, this method also helps to ensure the accuracy and predictability of the AC voltage regulation across the electroluminescent element I130, thereby ensuring the accuracy of brightness adjustment.

[0075] As discussed above, in the drive adjustment device of the present invention, the first drive level DRVA and the second drive level DRVB, which are in phase with the first clock signal CLKA and the second clock signal CLKB, are respectively applied to the two electrodes of the electroluminescent element I130, and the phase difference between them is... The effective value (RMS) of the AC voltage applied across the electroluminescent element I130 is directly determined, i.e., the voltage level (DRVA-DRVB) applied to the two electrodes of the electroluminescent element I130 and its phase difference. The relevant bipolar AC signal, wherein the effective value (RMS) of the AC voltage is:

[0076] RMS=VPP* (0 ),

[0077] RMS=VPP* (180 ),

[0078] Wherein, RMS is the effective value of the AC voltage. VPP is the phase difference between the first clock signal CLKA and the second clock signal CLKB, and VPP is the voltage when the first drive level DRVA / second drive level DRVB is in a high-level state.

[0079] As can be seen from the above, when the phase difference between the first clock signal CLKA and the second clock signal CLKB... As the temperature changes from 0 degrees to 180 degrees, the effective value (RMS) of the AC voltage between the two electrodes of the electroluminescent element I130 gradually increases, and the effective value (RMS) of this AC voltage and the phase difference... The square root is proportional. When the phase difference between the first clock signal CLKA and the second clock signal CLKB... As the angle changes from 180 degrees to 360 degrees, the effective value (RMS) of the AC voltage between the two electrodes of the electroluminescent element I130 gradually decreases, and this effective value (RMS) of the AC voltage is related to (360°- It is proportional to the square root of ().

[0080] Therefore, this invention utilizes phase difference The method of adjusting the brightness of the electroluminescent element I130 transforms brightness control into a purely mathematically describable phase control problem. This explicit and continuously adjustable mathematical model (RMS=f( This method offers a smooth and user-friendly non-linear dimming feature. Through precise phase management control, it enables high-precision brightness control, facilitating the establishment of a digital feedback control mechanism. Furthermore, this method only requires phase adjustment to achieve precise brightness control, eliminating the need for additional complex circuit structures and simplifying circuit design.

[0081] like Figure 2 The diagram shows the waveform when the second clock signal CLKB lags the first clock signal CLKA by 90°. The phase difference between the first clock signal CLKA and the second clock signal CLKB is... When the angle is 90°, the effective value of the AC voltage RMS = VPP* =VPP / .

[0082] like Figure 3The diagram shows the waveform when the second clock signal CLKB lags the first clock signal CLKA by 180°. The phase difference between the first clock signal CLKA and the second clock signal CLKB is also shown. When the angle is 180°, the effective value of the AC voltage RMS = VPP* =VPP. From Figure 2 and Figure 3 It can be seen that when the phase difference between the first clock signal CLKA and the second clock signal CLKB... The difference is that the phase difference between the first drive level DRVA and the second drive level DRVB is not the same. At different times, the superposition waveform of the first driving level DRVA and the second driving level DRVB is different, which makes the effective value RMS of the AC voltage across the electroluminescent element I130 different, thus affecting the luminous brightness of the electroluminescent element I130.

[0083] Furthermore, based on the effective value (RMS) of the AC voltage and the phase difference... The nonlinear relationship between them means that when the effective value (RMS) of the AC voltage is small, i.e., when the brightness is low, the phase difference is small. Changes in phase difference can produce relatively large changes in the effective value (RMS) of the AC voltage, which in turn causes significant changes in brightness. Therefore, by controlling the phase difference... Fine-tuning can achieve rapid brightness adjustment and response. However, when the effective value of the AC voltage (RMS) approaches a preset threshold (e.g., the second preset voltage VPP), a large phase difference... The changes only cause small changes in the effective value (RMS) of the AC voltage and brightness, which is equivalent to providing a more delicate fine-tuning range visually. This prevents the sudden increase in brightness when it is too large from impacting the user's visual perception, and helps to bring users a more comfortable dimming experience, without the need for complex linearization correction circuits.

[0084] Optionally, the absolute value of the peak value of the AC voltage formed across the electroluminescent element I130 is greater than or equal to 75V. For example... Figure 2 As shown, when the phase difference When the angle is 90°, the AC voltage range is -VPP to VPP. When VPP is 75V, the AC voltage range across the electroluminescent element I130 in this embodiment is -75V to 75V. Based on this method, a sufficient and stable electric field driving foundation can be provided for the electroluminescent element I130, ensuring its luminous efficiency. Simultaneously, this method differs from the method in this invention that adjusts the phase difference... This aligns with the strategy for controlling brightness, providing a wide and controllable range of brightness adjustment.

[0085] Researchers have discovered that when the VPP voltage exceeds 80V, at a suitable driving frequency (e.g., 500Hz-10kHz), the brightness of the electroluminescent element I130 is monotonically positively correlated with the effective value (RMS) of the AC voltage applied between its two electrodes, while the RMS of the AC voltage between the two electrodes is related to the phase difference of the clock signal. The square root of the equation has a linear relationship; therefore, in this invention, the phase difference of the clock signal is controlled. It can effectively adjust the brightness of the I130 electroluminescent element.

[0086] In practical applications, the electroluminescent element I130 comes in various types, including luminescent fibers and EL devices. The EL devices include powder EL devices and thin-film EL devices. In powder EL devices, fluorescent powder is suspended in a dielectric material and sandwiched between two electrodes. Under a strong alternating electric field, the luminescent centers in the powder are excited by directly accelerated thermionic collisions. In practical applications, powder EL devices can be processed into dispersed EL panels / cold light sheets or EL linear structures. EL panels can be used in decorative lighting, while EL linear structures can be used in clothing, safety indicators, and other fields. Thin-film EL devices can be considered an upgraded version of powder EL devices. They mainly use inorganic materials such as zinc manganese sulfide, and are made into a uniform and dense thin film through processes such as vacuum deposition. This film is then sandwiched between two insulating films to form a sandwich structure. In practical applications, thin-film EL devices can be processed into AC thin-film electroluminescent displays, abbreviated as ACTFEL or TFEL, and can be applied in industrial control, medical, and other fields.

[0087] On the other hand, in practical applications, the clock phase modulation circuit I100 includes a controller and at least one clock signal generating device. The at least one clock signal generating device is used to generate a first clock signal CLKA and a second clock signal CLKB. The controller is used to control the phase difference between the first clock signal CLKA and the second clock signal CLKB generated by the clock signal generating device. This adjusts the phase difference between the first drive level DRVA and the second drive level DRVB. This allows for the adjustment of the brightness of the electroluminescent element I130.

[0088] like Figure 1As shown, the first clock level conversion driving circuit I110 includes a first level conversion control circuit I113 and a first amplifier circuit. The first level conversion control circuit I113 amplifies the first clock signal CLKA to generate a first driving signal. The input terminal of the first amplifier circuit is connected to the first level conversion control circuit I113, and its first output node is the output terminal of the first clock level conversion driving circuit I110. The first output node is connected to the first electrode of the electroluminescent element I130. The first amplifier circuit is powered by a first DC power supply. Under the control of the first driving signal, the first amplifier circuit can convert the voltage supplied by the first DC power supply (e.g., VPP) into a first driving level DRVA output.

[0089] Furthermore, the first amplifier circuit includes a first half-bridge circuit, which includes a first switch I111 and a second switch I112 connected in series. In this embodiment, the second switch I112 is a PMOS and the first switch I111 is an NMOS, which can be regarded as a high-level driving transistor and a low-level driving transistor, respectively. The drain of the first switch I111 is connected to a first DC power supply, and the source of the second switch I112 is grounded. The connection point between the source of the first switch I111 and the drain of the second switch I112 is defined as the first output node. In this embodiment, the first level conversion control circuit I113 can be a gate driving circuit, which amplifies the first clock signal CLKA and generates a first level signal PCTLA and a second level signal NCTLA that are opposite in phase, synchronous, and mutually exclusive, so that the first switch I111 and the second switch I112 are alternately turned on and off. Optionally, the range of the first level signal PCTLA can be 90V~100V, and the range of the second level signal NCTLA can be 0~5V, or the range of the second level signal NCTLA can be 0~10V.

[0090] Based on the above structure, when the first clock signal CLKA generated by the clock phase modulation circuit I100 is high (logic high), the first switch I111 is turned on and the second switch I112 is turned off, causing the first clock level conversion drive circuit I110 to output a high-level first drive level DRVA to the first electrode of the electroluminescent element I130. When the first clock signal CLKA is low (logic low), the first switch I111 is turned off and the second switch I112 is turned on, causing the first clock level conversion drive circuit I110 to output a low-level first drive level DRVA to the first electrode of the electroluminescent element I130.

[0091] Specifically, when the first clock signal CLKA is high, the first level conversion control circuit I113 converts the first clock signal CLKA into a first drive signal. The first drive signal includes a high-level first level signal PCTLA and a low-level second level signal NCTLA. Then, the first level conversion control circuit I113 applies the high-level first level signal PCTLA to the gate of the first switching transistor I111. Upon receiving the high-level first level signal PCTLA, the first switching transistor I111 turns on, forming a low-impedance path between its drain and source. Simultaneously, the first level conversion control circuit I113 applies the low-level second level signal NCTLA to the gate of the second switching transistor I112. Upon receiving the low-level second level signal NCTLA, the second switching transistor I112 turns off, resulting in a high-impedance state between its drain and source.

[0092] After the current from the first DC power supply flows out, it passes through the first conducting switch I111 and reaches the first output node. Since the second switch I112 is turned off, the current cannot flow directly to ground. At this time, the potential of the first output node is pulled up to a level close to the voltage VPP of the first DC power supply, forming a high-potential first drive level DRVA (approximately VPP) applied to the first electrode of the electroluminescent element I130.

[0093] When the first clock signal CLKA generated by the clock phase modulation circuit I100 is low, the first level conversion control circuit I113 generates a first level signal PCTLA that is low and a second level signal NCTLA that is high. The first level conversion control circuit I113 applies the low-level first level signal PCTLA to the gate of the first switching transistor I111, and the first switching transistor I111 quickly turns off upon receiving the low-level first level signal PCTLA. Simultaneously, the first level conversion control circuit I113 applies the high-level second level signal NCTLA to the gate of the second switching transistor I112, and the second switching transistor I112 turns on upon receiving the high-level second level signal NCTLA.

[0094] Because the first switch I111 is off, the current from the first DC power supply cannot flow to the first output node. Simultaneously, because the second switch I112 is on, a low-impedance path is established between the first output node and ground. At this time, the magnetic field energy stored at the load (e.g., the first electrode) will generate a freewheeling current. This freewheeling current flows out from the load, through the first output node, and then is released to ground through the on-state second switch I112. Therefore, during the period when the second switch I112 is on, the potential of the first output node is pulled down to near ground potential (approximately 0V), forming a low-potential first drive level DRVA.

[0095] In this embodiment, the structure of the second clock level conversion driver circuit I120 is the same as that of the first clock level conversion driver circuit I110. For example... Figure 1 As shown, the second clock level conversion driver circuit I120 includes a second level conversion control circuit I123 and a second amplifier circuit. The second level conversion control circuit I123 amplifies the second clock signal CLKB to generate a second drive signal. The input terminal of the second amplifier circuit is connected to the second level conversion control circuit I123, and its second output node is the output terminal of the second clock level conversion driver circuit I120. The second output node is connected to the second electrode of the electroluminescent element I130. The second amplifier circuit is powered by a second DC power supply. Under the control of the second drive signal, the second amplifier circuit can convert the voltage supplied by the second DC power supply (e.g., VPP) into a second drive level DRVB output.

[0096] Furthermore, the second amplifier circuit includes a second half-bridge circuit, which includes a third switch I121 and a fourth switch I122 connected in series. In this embodiment, the fourth switch I122 is a PMOS and the third switch I121 is an NMOS, which can be regarded as a high-level driving transistor and a low-level driving transistor, respectively. The drain of the third switch I121 is connected to a second DC power supply, and the source of the fourth switch I122 is grounded. The connection point between the source of the third switch I121 and the drain of the fourth switch I122 is defined as the second output node. In this embodiment, the second level conversion control circuit I123 can be a gate driving circuit, which amplifies the second clock signal CLKB and generates a third level signal PCTLB and a fourth level signal NCTLB that are opposite in phase, synchronous, and mutually exclusive, so that the third switch I121 and the fourth switch I122 are alternately turned on and off.

[0097] Based on the above structure, when the second clock signal CLKB generated by the clock phase modulation circuit I100 is high, the third switch I121 is turned on and the fourth switch I122 is turned off, causing the second clock level conversion drive circuit I120 to output a high-level second drive level DRVB to the second electrode of the electroluminescent element I130. When the second clock signal CLKB is low, the third switch I121 is turned off and the fourth switch I122 is turned on, causing the second clock level conversion drive circuit I120 to output a low-level second drive level DRVB to the second electrode of the electroluminescent element I130. The processing of the second clock signal CLKB by the second clock level conversion drive circuit I120 and the signal changes therein are similar to the processing of the first clock signal CLKA by the first clock level conversion drive circuit I110 described above, and will not be repeated here.

[0098] It should be noted that the structural composition of the clock phase modulation circuit I100, the first clock level conversion drive circuit I110, and the second clock level conversion drive circuit I120 in this invention is not limited to the above examples. In other embodiments, they can be any other structures that can achieve the same or similar functions, and this invention does not limit them. Similarly, the structural composition of the first level conversion control circuit I113, the first amplifier circuit, the second level conversion control circuit I123, and the second amplifier circuit can also be in other forms. The first switch I111, the second switch I112, the third switch I121, and the fourth switch I122 are not limited to the above forms. For example, in some embodiments, the first switch I111 and the second switch I112 are both NMOS, and their corresponding first level signal PCTLA and second level signal NCTLA can be set accordingly.

[0099] On the other hand, it should be noted that the electroluminescent element in this invention is not limited to the electroluminescent element I130 described above. In other embodiments, it can also be other types of elements, and this invention does not limit this. That is, the driving and adjusting device of this invention is not limited to driving and adjusting the electroluminescent element I130 described above. For example, in some embodiments, the electroluminescent element is an electrochromic element. Under the action of the applied voltage / electric field of the driving and adjusting device, the optical properties (e.g., color, transparency, reflectivity, etc.) of the electrochromic element will undergo reversible and controllable changes. At the same time, the driving and adjusting device can meet the high requirements of the electrochromic element for dimming continuity, response speed, cost budget, and power consumption. In practical applications, the electrochromic element can be at least one of electrochromic (EC), suspended particle (SPD), dye liquid crystal (DLC), and polymer dispersed liquid crystal (PDLC), and can be applied to dimming glass (automotive glass, conference room glass, etc.), dimming canopy, sunshade system, etc.

[0100] Example 2

[0101] Based on the clock phase difference in Embodiment 1 The characteristics of the drive adjustment device for the controlled electroluminescent element I130 are modified in this embodiment, particularly in terms of signal generation, conversion, and regulation.

[0102] like Figure 4 As shown, this is another method based on clock phase difference according to the present invention. A schematic diagram of a driving and regulating device for a controlled electroluminescent element I230. In this embodiment, the driving and regulating device is used to independently drive and regulate at least two electroluminescent elements I230. The driving and regulating device includes a clock phase modulation circuit I200, at least one first clock level conversion driving circuit I210, and at least one second clock level conversion driving circuit I220. The clock phase modulation circuit I200 is used to generate at least two first clock signals CLKA and at least two corresponding second clock signals CLKB, wherein each first clock signal CLKA is independent of the others, and each second clock signal CLKB is independent of the others.

[0103] like Figure 5 As shown, the first clock signals CLKA generated by the clock phase modulation circuit I200 are identical. The drive adjustment device includes a first clock level conversion drive circuit I210, which converts the first clock signal CLKA into a first drive level DRVA, which is then applied to the first electrode of each electroluminescent element I230. In this method, the first clock signal CLKA modulated by the clock phase modulation circuit I200 is equivalent to the common clock signal when driving multiple electroluminescent elements I230, which helps to ensure that the first drive level DRVA is applied synchronously to the first electrode of each electroluminescent element I230, ensuring the timing consistency and electrical characteristic consistency of the first drive level DRVA at each first electrode. At the same time, this method highly centralizes clock generation and phase modulation, eliminating the need to equip each electroluminescent element I230 with an independent clock generator and modulation circuit, which helps to simplify the system architecture and reduce hardware costs.

[0104] Furthermore, the clock phase modulation circuit I200 generates at least two different second clock signals CLKB. The driving adjustment device correspondingly includes at least two second clock level conversion driving circuits I220. Each second clock level conversion driving circuit I220 converts each second clock signal CLKB into a second driving level DRVB, which is then applied to the second electrode of each electroluminescent element I230. A single second clock signal CLKB and its corresponding second clock level conversion driving circuit I220 can be considered as a signal channel for a group of electroluminescent elements I230. It is understood that a group of electroluminescent elements I230 includes one or more electroluminescent elements I230.

[0105] Based on the above method, each group of electroluminescent elements I230 has a dedicated second clock signal CLKB and a second clock level conversion drive circuit I220, so that each group of electroluminescent elements I230 has an independent control channel, thereby adjusting the brightness variable (phase difference). This method allows for independent and isolated settings and adjustments, enabling independent and precise control of each group of electroluminescent elements (I230). It also achieves signal isolation between different groups of I230 elements, preventing mutual interference and helping to ensure the brightness control accuracy and overall stability of each group. Furthermore, this method simplifies brightness control to a purely single-path phase difference. Adjustment, based on the common first clock signal CLKA and the first clock level conversion driver circuit I210, only requires considering the phase difference between the corresponding second clock signal CLKB and the first clock signal CLKA for each group of electroluminescent elements I230. This simplifies the control factors. On the other hand, since the control channels of each group of electroluminescent elements I230 are independent, the drive adjustment device has modular characteristics, which is beneficial to the expandability of the drive channels in the drive adjustment device. When a new drive channel needs to be added, there is no need to add a new clock source and a first clock level conversion drive circuit I210. Only the corresponding second clock level conversion drive circuit I220 needs to be added, which greatly reduces the complexity of the device.

[0106] In this embodiment, the frequency of the first clock signal CLKA is F, the high level is the first preset voltage VCC, and the low level is 0V. The first clock level conversion drive circuit I210 converts the first clock signal CLKA into a first drive level DRVA (high voltage drive signal), which has a frequency of F, a high level is the second preset voltage VPP, and a low level is 0V. Additionally, in this embodiment, a set of electroluminescent elements I230 includes one electroluminescent element I230, and the clock phase modulation circuit I200 generates n second clock signals CLKB. <1> ~CLKB <n>That is, each independent clock signal drives the adjustment device to have n second clock level conversion drive circuits I220. <1> ~ I220 <n>To respectively target n electroluminescent elements I230 <1> ~I230 <n>Drive and adjust.

[0108] like Figure 5 As shown, during operation, the clock phase modulation circuit I200 modulates multiple common clock signals (first clock signal CLKA) to drive multiple electroluminescent elements I230, and multiple independent clock signals (second clock signals CLKB) to control each electroluminescent element I230. <1> ~CLKB <n>This is a phase-controlled clock, where the device allows the output of any n independent clock signals.

[0109] like Figure 5 As shown, this is the second clock signal CLKB. <1> The first clock signal CLKA lags behind the second clock signal CLKB by 90°. <n>A waveform diagram showing the first clock signal CLKA lagging by 180°. Based on the brightness control requirements of each electroluminescent element I230, the phase of each second clock signal CLKB can be adjusted to adjust the corresponding phase difference. This allows for the adjustment of the brightness of the corresponding electroluminescent element I230.

[0110] It is understood that in practical applications, the first clock signals CLKA and the second clock signals CLKB are not limited to the above-described forms. In other embodiments, they may also be in other forms and combinations. Optionally, in some embodiments, at least two first clock signals CLKA are different, and the drive adjustment device includes at least two first clock level conversion drive circuits I210. Each first clock level conversion drive circuit I210 converts each first clock signal CLKA into a first drive level DRVA and applies it to the first electrode of each electroluminescent element I230. Based on this method, an independent first drive level DRVA adjustment channel can be provided for each group of electroluminescent elements I230, which helps to realize independent and parallel drive control of different regions in the electroluminescent element I230 array.

[0111] In practical applications, when this method is combined with a scheme where all second clock signals CLKB are the same, its advantages are similar to those of the scheme described earlier, where "all first clock signals CLKA are the same + at least two second clock signals CLKB are different," and will not be elaborated further here. When this method is combined with a scheme where the second clock signals CLKB are not completely identical, each group of electroluminescent elements I230 has two electrodes with a control channel. When the brightness of a certain group of electroluminescent elements I230 needs to be adjusted, at least one of its corresponding first clock signal CLKA and second clock signal CLKB can be controlled, providing high flexibility. Therefore, this method allows for independent control of the two electrodes of each electroluminescent element I230, achieving the finest pixel-level or sub-pixel-level control, i.e., the highest level of control freedom.

[0112] On the other hand, in some embodiments, the various second clock signals CLKB are identical. The drive adjustment device includes a second clock level conversion drive circuit I220, which converts the second clock signal CLKB into a second drive level DRVB, which is then applied to the second electrode of each electroluminescent element I230. Based on this method, a common clock signal can be provided for each group of electroluminescent elements I230, ensuring the consistency of the second drive level DRVB applied at the second electrode of the electroluminescent elements I230.

[0113] In practical applications, when this method is combined with a scheme where the first clock signal CLKA is not exactly the same, its advantages are similar to those of the scheme described above where "all first clock signals CLKA are the same + at least two second clock signals CLKB are different", which will not be repeated here. When this method is combined with a scheme where all first clock signals CLKA are the same, the scheme in Example 1 is formed.

[0114] Furthermore, other structures and the connections and functions of each component in this embodiment, such as the structure of the clock phase modulation circuit I200, the first clock level conversion drive circuit I210, and the second clock level conversion drive circuit I220, can be similar to or the same as those in Embodiment 1, and will not be described or limited here.

[0115] Based on the same inventive concept, this invention also provides a method based on clock phase difference. A method for operating a drive adjustment device for a controlled electro-hydraulic element, the method comprising:

[0116] S1, Clock phase modulation circuit I100 generates at least one first clock signal CLKA and at least one second clock signal CLKB;

[0117] S2. The first clock level conversion driving circuit I110 converts the first clock signal CLKA into a first driving level DRVA and applies it to the first electrode of the electrodynamic element; the second clock level conversion driving circuit I120 converts the second clock signal CLKB into a second driving level DRVB and applies it to the second electrode of the electrodynamic element; wherein, when it is necessary to adjust the electrodynamic element, the clock phase modulation circuit I100 adjusts the phase difference between the first clock signal CLKA and its corresponding second clock signal CLKB. The effective value (RMS) of the AC voltage applied across the same electro-electrode is adjusted to regulate the electro-electrode (e.g., to adjust its brightness or color characteristics). Based on the above, the electro-electrode can be driven and controlled. This low-voltage logic signal control mechanism enables effective regulation of the electro-electrode, offering advantages such as simplicity, high efficiency, fast response speed, high precision, and high flexibility.

[0118] Furthermore, when the driving adjustment device is used to independently drive and regulate at least two electroluminescent elements, in this method, the clock phase modulation circuit I100 generates at least two first clock signals CLKA and at least two second clock signals CLKB, and the clock phase modulation circuit I100 adjusts the phase difference between each first clock signal CLKA and its corresponding second clock signal CLKB. This allows for the individual adjustment of each electro-actuated element. Based on this method, independent adjustment of multiple electro-actuated elements can be achieved.

[0119] Based on the same inventive concept, the present invention also provides a device comprising: at least one electro-energizing element and the aforementioned clock phase difference-based device. A drive adjustment device for a controlled electro-electro ...

[0120] For example, in some embodiments, the device is a light-emitting device that includes at least one electroluminescent element I130 and the aforementioned clock phase difference-based [mechanism / mechanism]. A drive adjustment device for a controlled electroluminescent element, the drive adjustment device being used to drive at least one electroluminescent element and adjust its brightness. In practical applications, the light-emitting device can be a smart bracelet, smartwatch, smart clothing, etc. When the electroluminescent element I130 is a flexible structure such as a luminescent fiber or a flexible luminescent panel, the light-emitting device can be a luminescent fabric device, such as smart clothing. The fabric part of the luminescent fabric device can be composed solely of an array of electroluminescent elements I130 (e.g., an array of luminescent fibers), or it can be composed of an array of luminescent fibers and textile materials (e.g., natural material threads, polymer threads, leather, etc.).

[0121] In summary, the present invention provides a method based on clock phase difference. In the controlled electro-electro-electrode drive adjustment device, method, and apparatus, the device combines a clock phase modulation circuit I100, a first clock level conversion drive circuit I110, and a second clock level conversion drive circuit I120. The clock phase modulation circuit I100 generates two low-voltage clock signals, and the two clock level conversion drive circuits convert these two low-voltage clock signals into two high-voltage drive signals, which are then applied to the two electrodes of the electro-electrode. In practical applications, the phase difference between the two low-voltage clock signals is controlled. This control method enables the driving and regulation of electro-hydraulic components. It eliminates the need for large transformers, requiring only the phase difference between two low-voltage clock signals. By adjusting the voltage, the effective value (RMS) of the AC voltage across the electro-electro-electrode can be changed, thereby regulating the electro-electro-electrode. This method is simple, efficient, and has a fast response speed.
