Description

Constant-temperature liquid crystal phased array based on semiconductor technology and temperature regulation method thereof TECHNICAL FIELD

[0001] The present application relates to liquid crystal phased array technology, in particular to a constant-temperature liquid crystal phased array based on semiconductor technology and a temperature regulation method thereof. BACKGROUND

[0002] To meet the needs of mobile terminals in L, C, Ku, Ka or W band operation of various services, such as wireless Internet, multimedia, communication and broadcast services, electronic reconfigurable millimeter wave system with its small size, multi-function, high spectral efficiency, flexibility and other advantages has become the current research hotspot, used for military and industrial ground station applications, including airborne, shipborne or automotive mobile terminals. The technical methods commonly used for phased array beam scanning include radio frequency micro-electromechanical system (RF MEMS), semiconductor solutions and ferroelectrics such as barium strontium titanate (BST). Another method is to use liquid crystal materials with low loss at high frequency bands. Among these methods, liquid crystal is superior to MEMS in terms of life, continuity and packaging; it is superior to BST in terms of frequency range and bias voltage, and is an ideal material for developing beam scanning phased arrays. Liquid crystal display panels have mature manufacturing processes, so liquid crystal phased arrays also have unique advantages in manufacturing costs. In the third generation partnership and new radio bands, liquid crystal-based phased array modules with cost competitiveness and high performance can support the ability of beamforming and beam steering, which are key technologies for emerging small cell base stations and client devices. Therefore, the study of liquid crystal phased arrays suitable for various mobile terminals is of great significance to wireless communication systems. However, the performance of liquid crystal phased arrays is greatly affected by temperature. Changes in temperature can cause changes in the physical properties of liquid crystals, affecting the phase control accuracy, beam pointing accuracy and signal transmission quality of the phased array.

[0003] Traditional heat dissipation or temperature control methods have certain limitations in efficiency, accuracy and adaptability, and are difficult to meet the temperature stability requirements of liquid crystal phased arrays in complex working environments and high performance requirements.

[0004] Liquid crystal phased arrays are usually used for beam scanning and phase control, which requires adjusting the phase of electromagnetic waves by changing the arrangement of liquid crystal molecules. During the operation of the liquid crystal phased array module, the arrangement state of the liquid crystal molecules needs to be frequently adjusted as needed to achieve dynamic regulation. When the direction or phase of the beam needs to be changed, the arrangement state of the liquid crystal molecules needs to be adjusted by an external electric field, and the liquid crystal molecules are rearranged under the action of the external electric field and return to the initial state after the electric field is removed, thereby preparing for the next adjustment of the arrangement state. However, the existing liquid crystal phased array system relies on the natural recovery of liquid crystal molecules, and the recovery speed is slow, which limits the adjustment speed of the liquid crystal phased array in adjusting the beam direction or phase.

[0005] It is to be noted that the information disclosed in the above BACKGROUND section is only for the purpose of understanding the background of the present application, and thus can include information that does not constitute the prior art known to those of ordinary skill in the art. SUMMARY

[0006] The main object of the present application is to solve the problems existing in the above BACKGROUND, and to provide a constant-temperature liquid crystal phased array based on semiconductor technology and a temperature control method thereof.

[0007] To achieve the above object, the present application adopts the following technical solutions:

[0008] A constant-temperature liquid crystal phased array based on semiconductor technology, comprising a liquid crystal phased array module, a semiconductor temperature control module, a temperature sensor, a power supply and a control unit; the liquid crystal phased array module comprises a quartz glass upper substrate, a quartz glass lower substrate, a liquid crystal material arranged between the quartz glass upper substrate and the quartz glass lower substrate, a feed network arranged on the upper surface of the quartz glass lower substrate, a metal ground arranged on the lower surface of the quartz glass upper substrate, and an array unit arranged on the quartz glass upper substrate; the semiconductor temperature control module is arranged on the lower surface of the quartz glass lower substrate and comprises a ceramic upper substrate, a ceramic lower substrate, a metal conductor arranged between the ceramic upper substrate and the ceramic lower substrate, an N-type semiconductor and a P-type semiconductor; the metal conductor, the N-type semiconductor and the P-type semiconductor are connected in a power supply loop, and heating or cooling of the liquid crystal phased array module is realized by changing the current direction; the temperature sensor is arranged to detect the temperature of the liquid crystal phased array module; the control unit is connected with the semiconductor temperature control module and the temperature sensor, receives signals from the temperature sensor, and controls the working state of the semiconductor temperature control module to control the temperature of the liquid crystal phased array module within a preset temperature range.

[0011] The liquid crystal phased array module and the semiconductor temperature control module are integrated by a heat-cured glue uniformly distributed between the quartz glass lower substrate and the ceramic upper substrate.

[0012] During the working process of the liquid crystal phased array module, when it is monitored that the voltage applied to the liquid crystal molecules to exert an external electric field is removed, the control unit controls the semiconductor temperature control module to heat the liquid crystal phased array module, so as to accelerate the recovery process of the liquid crystal molecules to return to the initial arrangement state.

[0013] During the recovery process of the liquid crystal molecules, the control unit monitors the temperature of the liquid crystal phased array in real time and compares it with the preset optimal recovery temperature. If the temperature of the liquid crystal phased array is lower than the preset optimal recovery temperature, the control unit controls the working state of the semiconductor temperature control module to continue heating the liquid crystal phased array until the preset optimal recovery temperature is reached.

[0014] The control unit compares the temperature detected by the temperature sensor with a preset temperature range. If the temperature is higher than the upper limit of the preset temperature range, the control unit controls the semiconductor temperature control module to cool until the temperature detected by the temperature sensor falls within the preset temperature range. If the temperature is lower than the lower limit of the preset temperature range, the control unit controls the semiconductor temperature control module to heat until the temperature detected by the temperature sensor rises within the preset temperature range.

[0016] The temperature sensor detects the temperature of the liquid crystal phased array module.

[0017] The control unit receives the temperature signal detected by the temperature sensor and controls the working state of the semiconductor temperature control module according to the temperature signal to turn on heating or cooling to regulate the temperature of the liquid crystal phased array module within a preset temperature range.

[0020] During the recovery process of the liquid crystal molecules, the control unit monitors the temperature of the liquid crystal phased array in real time and compares it with the preset optimal recovery temperature. If the temperature of the liquid crystal phased array is lower than the preset optimal recovery temperature, the control unit controls the working state of the semiconductor temperature control module to continue heating the liquid crystal phased array until the preset optimal recovery temperature is reached.

[0021] The control unit compares the temperature detected by the temperature sensor with a preset temperature range, if the temperature is higher than the upper limit of the preset temperature range, the control unit controls the semiconductor temperature control module to cool until the temperature detected by the temperature sensor falls within the preset temperature range, if the temperature is lower than the lower limit of the preset temperature range, the control unit controls the semiconductor temperature control module to heat until the temperature detected by the temperature sensor rises within the preset temperature range.

The temperature sensor is distributed between the quartz glass substrate of the liquid crystal phased array module and the ceramic substrate of the semiconductor temperature control module, and detects the temperature of the liquid crystal phased array in real time. The control unit dynamically adjusts the current direction and intensity of the semiconductor temperature control module based on the comparison of the received temperature signal with the preset temperature range, to maintain the optimal working temperature of the liquid crystal phased array. The system can maintain the stable operation of the liquid crystal phased array under different environmental temperatures through closed-loop control, and improve the natural recovery speed of the liquid crystal molecules.

[0023] The present application has the following advantages:

[0024] The present application realizes temperature control by introducing a semiconductor structure into the liquid crystal phased array system, which not only enables the liquid crystal phased array to always work within the optimal temperature range, providing a constant-temperature liquid crystal phased array system, but also effectively solves the problems of the liquid crystal phased array system being affected by environmental temperature changes and the slow natural recovery of liquid crystal molecules, realizing stable operation of the liquid crystal phased array under different stable temperature environments and fast natural recovery response, and improving the dynamic control speed.

Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0041] Referring to FIG. 1 and FIG. 2, the embodiment of the present application provides a constant temperature liquid crystal phased array based on semiconductor technology, comprising a liquid crystal phased array module, a semiconductor temperature control module, a temperature sensor, a power supply and a control unit; the liquid crystal phased array module comprises a quartz glass upper substrate 102, a quartz glass lower substrate 106, a liquid crystal material 104 arranged between the quartz glass upper substrate 102 and the quartz glass lower substrate 106, a feed network 105 arranged on the upper surface of the quartz glass lower substrate 106, a metal ground 103 arranged on the lower surface of the quartz glass upper substrate 102, and an array unit 101 arranged on the quartz glass upper substrate 102; the semiconductor temperature control module is arranged on the lower surface of the quartz glass lower substrate 106 and comprises a ceramic upper substrate 107, a ceramic lower substrate 110, a metal conductor 108 arranged between the ceramic upper substrate 107 and the ceramic lower substrate 110, and a semiconductor 109, wherein the semiconductor 109 comprises an N-type semiconductor and a P-type semiconductor, the metal conductor 108, the N-type semiconductor and the P-type semiconductor are connected in a power supply loop, and heating or cooling of the liquid crystal phased array module is achieved by changing the current direction; the temperature sensor is arranged to detect the temperature of the liquid crystal phased array module; the control unit is connected with the semiconductor temperature control module and the temperature sensor, receives signals from the temperature sensor, and controls the working state of the semiconductor temperature control module to regulate the temperature of the liquid crystal phased array module within a preset temperature range.

[0042] In a preferred embodiment, during the operation of the liquid crystal phased array module, when it is monitored that the voltage applied to the liquid crystal molecules to exert an external electric field is removed, the control unit controls the semiconductor temperature control module to heat the liquid crystal phased array module to accelerate the recovery process of the liquid crystal molecules to return to the initial arrangement state (see FIG. 5). Further, during the recovery process of the liquid crystal molecules, the control unit monitors the temperature of the liquid crystal phased array in real time and compares it with a preset optimal recovery temperature, and if the temperature of the liquid crystal phased array is lower than the preset optimal recovery temperature, the control unit controls the working state of the semiconductor temperature control module to continue to heat the liquid crystal phased array until the preset optimal recovery temperature is reached (see FIG. 4). Compared with the conventional liquid crystal phased array, when the direct current voltage is removed, the natural recovery process of the liquid crystal molecules to return to the initial arrangement state is generally slow and difficult to meet the requirement of fast regulation and control response, and the present application can effectively improve the performance of the liquid crystal phased array to achieve fast response in dynamic regulation and control.

[0043] The application is based on a semiconductor technology temperature-controlled liquid crystal phased array system. The liquid crystal phased array module, temperature sensor, semiconductor temperature control module, control unit and power module constitute a closed-loop control system. The temperature of the liquid crystal phased array is monitored in real time by the temperature sensor, and the monitored temperature signal is fed back to the control unit. The control unit dynamically adjusts the working state of the semiconductor temperature control module according to the received temperature signal and the preset temperature target, so as to realize accurate temperature control of the liquid crystal phased array module. The semiconductor technology temperature-controlled liquid crystal phased array system of the application can keep the stable operation of the liquid crystal phased array under different temperature environments. The application can significantly accelerate the natural recovery response of the liquid crystal molecules, thereby improving the response speed of the liquid crystal phased array when the beam direction or phase needs to be frequently adjusted, so as to better meet the demand for fast dynamic regulation, and has the potential to be widely applied in the field of future wireless communication.

[0044] The specific embodiments of the application are further described below.

[0045] The semiconductor technology temperature-controlled liquid crystal phased array system of the application includes the following parts: a liquid crystal phased array module including an array unit column, a feed network, a liquid crystal material and upper and lower quartz glass substrates, for realizing phase control and direction adjustment of a beam. The semiconductor temperature control module is composed of a semiconductor refrigeration ceramic sheet, a heat dissipation ceramic sheet, a metal conductor, an N-type and a P-type semiconductor, and realizes refrigeration or heating effect through current control. The temperature sensor is distributed at a position effective for measuring the temperature of the liquid crystal phased array module, and monitors the temperature change in real time. The control unit receives the signal of the temperature sensor, and controls the working state of the semiconductor refrigeration\heating ceramic sheet according to the preset temperature range.

[0046] The overall structure of the system is shown in FIG. 1. The liquid crystal phased array module, temperature sensor, semiconductor temperature control module, control unit and power module jointly constitute a closed-loop control system. The temperature of the liquid crystal phased array is monitored in real time by the temperature sensor, and the temperature signal is fed back to the control unit. The control unit adjusts the working state of the semiconductor temperature control module according to the temperature signal and the preset temperature target, so as to realize temperature control of the liquid crystal phased array module.

[0047] In some embodiments, the temperature sensor monitors the temperature of the liquid crystal phased array in real time, and transmits data to the control unit. The control unit compares the received temperature with the preset optimal working temperature range. If the temperature is higher than the upper limit, the control unit starts the semiconductor refrigeration ceramic sheet to take away heat until the temperature drops to the appropriate range. If the temperature is lower than the lower limit, the control unit switches the semiconductor heating ceramic sheet to provide heat for the liquid crystal phased array, so as to ensure its normal work.

[0048] In some embodiments, a temperature-controlled liquid crystal phased array system based on semiconductor technology includes a liquid crystal phased array module, a temperature sensor, a semiconductor temperature control module, a control unit, and a power module, as shown in Figure 1. Among them, the liquid crystal phased array module is composed of array unit 101, quartz glass upper substrate 102, metal ground 103, liquid crystal material 104, feed network 105, quartz glass lower substrate 106; the semiconductor temperature control module is composed of ceramic upper substrate 107, metal conductor 108, ceramic lower substrate 110, semiconductor 109 (N-type and P-type semiconductor). The temperature sensor is loaded between the quartz glass lower substrate 106 and the ceramic upper substrate 107, the control unit and the power module are integrated on the external board card. The liquid crystal phased array module and the semiconductor temperature control module are integrated by the heat-curing glue evenly distributed between the quartz glass lower substrate 106 and the ceramic upper substrate 107.

[0049] The principle of the semiconductor temperature control module is shown in Figure 2, the P-type semiconductor material and the N-type semiconductor material are ingeniously integrated and combined. When direct current flows through the integrated structure, heat absorption or release phenomenon occurs at the contact point of the two materials. This phenomenon is based on the difference in energy state between P-type and N-type semiconductor materials during the migration of electrons. By adjusting the direction of the current, precise control of heat absorption and release at the contact point can be achieved, thereby selectively cooling or heating at a specific location.

[0050] The environmental temperature control logic diagram of the semiconductor technology-based temperature-controlled liquid crystal phased array system according to an embodiment of the present application is shown in Figure 3, and the temperature control method specifically includes:

[0051] Start: initialize system components (liquid crystal phased array module, temperature sensor, control unit, semiconductor temperature control module), including powering the system and establishing communication between the control unit and all modules.

[0052] Temperature monitoring: continuously monitor the temperature through the temperature sensors distributed in the liquid crystal phased array. The temperature sensor provides real-time data, which is crucial for maintaining the performance of the liquid crystal phased array.

[0053] Temperature evaluation: compare the measured temperature with the preset optimal temperature range. If the temperature is within the range, keep the current state (idle). The control unit evaluates whether the current temperature needs to be adjusted.

[0054] Temperature adjustment: according to the deviation of the temperature, the system cools or heats the liquid crystal phased array, wherein:

[0055] 1) If the temperature exceeds the upper limit, activate the semiconductor refrigeration module to reduce the temperature, and monitor the temperature until it returns to the optimal range.

[0056] 2) If the temperature is below the lower limit, activate the semiconductor heating module to raise the temperature, monitor the temperature until it returns to the optimal range.

[0057] System feedback: Continuously feed the data from the temperature sensor to the control unit to adjust the cooling / heating operation, check if the adjustment has restored the temperature to the expected range.

[0058] Return to the temperature monitoring step, repeat the process to ensure that the system is maintained within the optimal temperature range.

[0059] The fast response temperature control logic diagram of a semiconductor technology-based temperature control liquid crystal phased array system according to an embodiment of the present application is shown in FIG. 4, and the temperature control method specifically includes:

[0060] Start: Initialize system components, including liquid crystal phased array, temperature sensor, control unit, semiconductor temperature control module.

[0061] Voltage regulation: Apply voltage to the liquid crystal phased array to make the liquid crystal molecules align and arrange, achieving the desired phased array effect.

[0062] Voltage removal: Remove the voltage, and the liquid crystal molecules begin to naturally recover.

[0063] Temperature rapid rise: Immediately after voltage removal, quickly raise the temperature through the temperature control module to speed up the movement of the liquid crystal molecules, thereby speeding up the recovery process.

[0064] Temperature monitoring: Real-time monitoring of the recovery temperature of the liquid crystal phased array, if the optimal recovery temperature is not reached, continue to raise the temperature (the optimal response time is set by the test personnel system).

[0065] If the recovery temperature meets the set range: Maintain the current temperature or appropriately lower the temperature to save energy.

[0066] System feedback: Feed the temperature and recovery time data to the control unit for dynamic adjustment of the temperature setting.

[0067] Return to the voltage regulation step, repeat the process to ensure that the response time of the liquid crystal molecules is always in the fastest state.

[0068] As shown in FIG. 5, the temperature control mechanism of the present application is also applied to accelerate the recovery response time of liquid crystal molecules. When no voltage is applied, the liquid crystal molecules spontaneously arrange due to the presence of the alignment layer, forming a layered structure consistent with the direction of the alignment layer, which is the initial state of the liquid crystal after packaging; when a direct current voltage is applied, the liquid crystal molecules gradually rearrange under the action of the applied electric field, with their long axes pointing in the direction of the electric field; when the direct current voltage is removed, the liquid crystal molecules will naturally return to the initial arrangement state. However, this natural recovery process of the liquid crystal molecules is usually relatively slow, making it difficult to meet the requirements of liquid crystal phased array in fast regulation response time. Therefore, the present application controls the semiconductor temperature control module to increase the temperature of the liquid crystal phased array to the set optimal recovery temperature during the recovery process of the liquid crystal molecules, thereby effectively accelerating the regulation response speed of the liquid crystal phased array.

[0069] In summary, the present application provides a temperature-controlled liquid crystal phased array system based on semiconductor technology, which realizes accurate control of the working temperature of the liquid crystal phased array by introducing semiconductor temperature control technology, thereby improving the stability and dynamic regulation speed of the system. The system has wide application prospects and provides a new solution for the development of liquid crystal phased array technology.
