Description
Technical Field
the invention relates to the technical field of display devices, in particular to a control device and a control method of a transparent display device and the transparent display device.
Background
in the development of display screens, see-through display screens (see-through display panels) are one direction of their development. The current display screen technologies include TLCD (transparent LCD), OLED (organic light-emitting diode), plasma display (plasma display panel), also called self-luminous panel, etc. In addition, there are projection screens using a transparent holographic projection film (transparent holographic projection film). Recently, manufacturers have made trial samples to mass production, and korean manufacturer Samsung claims to start producing 22 ″ see-through liquid crystal display panel at 3 months 2011. Thereafter, the korean producer Samsung has also introduced a larger see-through lcd, including a diagonal 46 "display.
New products are put into the market, and new applications are initiated. One of the applications of the see-through display screen is to make a transparent light box for displaying objects. The invention discloses a lamp box, which is used for storing commodities such as drinks and foods and the like as display commodities, and is named as a transparent display module and application thereof, wherein the Chinese patent application number is CN 201210315770.6. And the side of the lamp box facing the observer is a transparent panel. The transparent panel can display advertisement image content and display commodities at the same time. By selecting the light and shadow arrangement of the advertisement image, the image of part of the transparent panel can be filled with the color and the observer can not see through the inside of the transparent lamp box, while the image of the other part of the transparent panel can be lighter or colorless and the observer can see through the inside of the transparent lamp box, namely, the transparent lamp box can change the perspective degree of different parts of the transparent panel by utilizing the advertisement image.
In addition, chinese patent application No. CN201220495946.6, the name of the utility model "transparent display box" discloses a transparent display box, at least one side of which is a liquid crystal display made of transparent material, and a display board for placing the displayed articles is provided with a turntable. This patent can provide one kind and can make the rotatory transparent show case of show commodity, also can cooperate at the transparent part of transparent liquid crystal display's advertisement image controlled display screen, and the observer can be should show the rotation of article and clearly see the front and back left and right parts of show article.
however, the above two technical solutions can only fixedly place the displayed article for displaying the article, or use the turntable to change the display angle of the article, so that the advertisement image playing is limited while displaying the article. Specifically, for example, when the display article is placed at the left position of the transparent display device, the advertisement image needs to be fixedly set aside at the left position to form a transparent viewing position when the display article is to be displayed. The function of the turntable can be utilized to perform limited position transfer, and the video and audio functions of the transparent display device can not be fully displayed, so that the display effect is poor. Meanwhile, in the prior art, a variable lighting technology is not utilized to highlight the displayed articles and match the played images to attract the observer. In the prior art, when a transparent display box is used as a promotion service for displaying physical goods, only a single article is displayed, for example, a travel journey is recommended, which is only expressed by a single character. Thus, a single display item does not fully represent a travel trip, nor does it provide good viewing for the viewer. Therefore, the prior transparent display device has poor display effect. The control device that does not provide a good transparent display device controls the transparent display device, and the user experience is poor.
in view of the above, the control technology of the prior transparent display device obviously has inconvenience and disadvantages in practical use, so that it is necessary to improve the control technology.

To adapt to the transmission needs of different control signals and more auxiliary control components can be connected.
Referring to fig. 8B, in one embodiment of the present invention, the microcontroller has an analog-to-digital converter and a digital-to-analog converter inside, which makes it capable of processing the transceiving of digital information (e.g., signal A, C in fig. 8B) and analog information (e.g., signal B, D in fig. 8B), except that the electrical characteristics of its corresponding line, such as voltage, electrical impedance, etc., must be consistent with the electrical characteristics of the microcontroller port. Thus, other transparent display components under the control of the microcontroller may be digital devices and/or emulation devices and/or hybrids thereof, controllable and/or associable with digital information and/or emulation information. The microcontroller in fig. 8B has digital and analog data buses to connect the other transparent display components, but in actual use each component may be connected by only one of the data lines.
In addition, because different microcontrollers have different numbers of external ports, the number of ports required by an external circuit may be greater than the number of external ports of the microcontroller. Therefore, multiplexers may be provided within the digital and analog data buses as needed for multiplexing. Typically the control of the multiplexer uses digital information and its channels may support digital and/or analog signals. Although not shown in the above figures, the multiplexers are understood to be part of the data bus. Therefore, if the emulation data bus needs to use a multiplexer, the digital signal for its control should also be understood as a part of the data bus.
In fig. 8B, one design of how to implement closed loop control with a microcontroller in a transparent display device is depicted based on the perspective of control logic, where the lines are logical relationships and not actual lines in fig. 8B, but the logical relationships may be composed of actual lines in fig. 8B, programming in the microcontroller, device components, physical connections, and the like. Microcontroller controlled transparent display device components include, but are not limited to, power control device 30, drive circuitry 40, lighting modules, movement modules, human interface module 10, and a series of sensing/measuring devices.
referring to fig. 8B, in the first embodiment of the present invention, the power device 30 includes a transformation system and a power distribution system;
The voltage transformation system converts the power transmitted by the external power device into direct current and/or alternating current for driving the transparent display device to work;
and the power distribution system outputs corresponding power to the transparent display device according to the electrical characteristics of the transparent display device.
in this embodiment, the power control device 30 basically has two parts, namely, a voltage transformation system and a power distribution system. The voltage transformation system includes, but is not limited to, an ac-dc converter, a dc-ac converter, a voltage converter, a current controller, etc. The voltage transformation system mainly converts external power into direct current and/or alternating current voltage and current required by different parts of the transparent display device, and supplies power to devices such as a built-in computer, a microcontroller and the like which do not need to be switched on and off due to display effect or power saving and the like for a long time. The power distribution system includes, but is not limited to, relays, transistors, etc. The power distribution system outputs power from the transformer system based on the electrical characteristics of each of the microcontroller controlled transparent display components, and each of the outputs may be switched on and off based on digital and/or simulated data received from the microcontroller to achieve a visual effect and/or effect. For example, to dim or dim the light inside the transparent display device, the light intensity can be adjusted by duty ratio by performing high-speed switching of the lighting module through the power control device by using pulse width modulation. For example, in order to save power or avoid overheat loss, the turntable motor is a stepping motor, and when the turntable stops for a certain period of time and no static torque is needed, the power supply to the drive circuit device is stopped, and the power to the motor and the drive circuit device is directly cut off.
in addition, in an embodiment of the present invention, the driving circuit device 40 may be composed of a plurality of driving circuits as a whole to drive one or more mobile modules. Each driving circuit includes, but is not limited to, an integrated circuit such as an H-bridge or a logic gate, and an individual relay or a transistor, which not only can drive the mobile module, but also plays an important role in redistribution. Taking the above-mentioned example of the turntable motor as an example, if the driving circuit device 40 drives more than one motor at the same time and one of the motors needs to stop supplying power, the power supply to the motor cannot be controlled by the power control device only, because the stop of the power supply to the driving circuit device will simultaneously terminate the power supply to all the motors. In this case, the driving circuit is required to redistribute power, and the power supply of one driving circuit to the motor is stopped according to the instruction of the microcontroller, while the other driving circuits and the related motors are not affected. In addition, each drive circuit may include one or more sensing/measuring devices to measure the electrical state of the mobile module and thereby infer its physical state, such as torque, angular position, etc.
In addition to the sensing/measuring devices in the driving circuit device 40, other sensing/measuring devices may be installed in the transparent display device, such as a sensing/measuring device physically connected to the mobile module, so as to provide another data about the physical state of the mobile module. In addition to the configuration shown in fig. 8B, the sensing/measuring device can be mounted on the access door of the transparent display to detect whether it is in an open or closed position, or mounted in the display space of the transparent display and on the device housing to detect the relative darkness of the interior and exterior of the device. The sensing/measuring device can be active or passive, the active device does not need to be controlled by an instruction, and the device can continuously or periodically output sensing data as long as the power control device supplies power; the passive device needs to receive the instruction and/or data to perform a detection and output a sensing data. Which sensing/measuring device is active/passive is not indicated in fig. 8B. In terms of control, the sensing/measuring devices can be basically divided into two categories, one is simple system input, as in the case of the access door above, the microcontroller does not control the access door, and the sensing data can only be used as a reference for the microcontroller, or can be used for open-loop control, such as stopping the rotation of the turntable, and the like. The other is more complex closed-loop control feedback, which is a necessary module for closed-loop control. The command and/or data transmission of all sensing/measuring devices can be of digital and/or analogue format.
For human interface module 10, it is capable of providing power to external low power devices in addition to interfacing with devices within the transparent display and/or with the computer and/or microcontroller within the device. Part B of FIG. 8 is a device such as a touch screen that is connected to a built-in computer only and is powered by a built-in computer port.
Referring to fig. 8C, in one embodiment of the present invention, the sensing device 50 comprises a feedback sensor;
The feedback inductor detects the working state of the driving device inside the transparent display device, and adjusts the driving device and/or the related work of the transparent display device according to the working state and the preset display work of the transparent display device. The feedback sensor is used for feeding back the internal condition of the transparent display device, for example, the synchronous motor can predict the movement condition of the driven component originally, for example, the synchronous motor can pour wine into a wine cup by inclining a wine bottle, and the feedback sensor can test the progress of the action to control the synchronous motor to continue or stop. A specific implementation may utilize a microcontroller to implement closed loop control as shown in fig. 8C.
Preferably, the feedback inductor is arranged in the closed loop control logic circuit; the closed loop control logic circuit comprises a microcontroller, a transparent display device system and the feedback inductor; the transparent display device system is provided with a reference value, the microcontroller receives an actual output value of the transparent display device system received by the feedback sensor, the microcontroller processes the actual output value and the reference value, calculates an error between the reference value and the actual value by mathematics and logic to obtain a required adjustment value, and outputs a control instruction to the control device, and the transparent display device system adjusts the output of the control device according to the transparent display device system. That is, the feedback sensor provides the actual output value of the present transparent display device system, and the microcontroller calculates the required adjustment value and sends an adjustment instruction to adjust the speed of the turntable, such as the light brightness. For example, the control target is a turntable speed of 50 revolutions per minute, the actually measured turntable speed is 48 revolutions per minute, the error is 2 revolutions per minute, the adjustment value obtained after calculation is X ampere of the reduction current, and the command is X ampere of the reduction current.
Referring to fig. 8C, closed loop control is implemented with a microcontroller within the transparent display. The closed loop control is mainly composed of three parts, namely a microcontroller, a transparent display device system and a feedback device (feedback inductor). The reference value represents an ideal value for controlling the transparent display device system, the microcontroller receives an error between an actual output of the transparent display device system and the reference value (the ideal output for controlling the transparent display device system), calculates a required adjustment value through mathematical and logical operations, and outputs a control instruction to the transparent display device system, and the transparent display device system adjusts the output of the transparent display device system according to the control instruction. Since the microcontroller uses an error between ideal and real-world, there must be a feedback sensing/measuring device in controlling the transparent display system to measure the actual output of the transparent display system as one of the inputs to the microcontroller. When the control is realized, the subtraction of the reference value and the feedback data, the logic operation of the microcontroller, the access change of the reference value and the like can be all operated by the microcontroller; the transparent display system may be composed of all the connections output from the microcontroller to the control target. According to the actual situation of implementing the closed-loop control, the reference value may be a preset value in the programming program of the microcontroller, or a value input to the microcontroller from the outside, or a processed value thereof.
Referring to fig. 8D, in one embodiment of the present invention, the feedback sensor comprises a velocity sensor;
The transparent display device system sets a turntable speed reference value, the microcontroller receives the speed of the actual turntable of the transparent display device system received by the speed sensor, the microcontroller calculates the error between the turntable speed reference value and the actual turntable speed by mathematics and logic to obtain a required adjustment value, and then outputs a control instruction to the transparent display device system, and the transparent display device system adjusts the output of the turntable speed of the target turntable according to the control instruction. The logic operation may use, but is not limited to, proportional-integral-derivative control, fuzzy logic control, artificial neural network control, and the like.
referring to fig. 8E, in one embodiment of the invention, the feedback sensor comprises a light darkness sensor;
The transparent display device system sets a light and darkness reference value, the microcontroller receives the light and darkness actually output by the transparent display device system and received by the light and darkness sensor, after the microcontroller arithmetically and logically calculates a required adjusting value according to the error between the light and darkness reference value and the actually output light and darkness, a control instruction is output to the transparent display device system, and the transparent display device system adjusts the output of the target light and darkness of the transparent display device system according to the control instruction. The microcontroller receives the target light darkness and the preset light darkness actually output by the control device, after the error between the light darkness reference value and the actual light darkness is arithmetically and logically operated to obtain a required adjusting value, the microcontroller outputs a control instruction to the control device, and the control device adjusts the target light darkness output of the control device according to the control instruction. The logic operation may use, but is not limited to, proportional-integral-derivative control, fuzzy logic control, artificial neural network control, and the like.
Fig. 8E and 8D show two closed-loop control logics for controlling the rotation speed of the turntable and the light darkness of the lamp, respectively.
