Description

Technical Field

[0001] The utility model relates to the technical field of oven control, in particular to a transparent display and touch control structure used on an oven door. Background Art

[0002] In the current oven market, due to the influence of traditional products, the operating interface of the oven is still mainly developed with mechanical buttons or knobs, and scale markings are the main display method, such as the set function, mode, temperature and time, etc. Although a small LCD screen has been added to the oven body as a screen display carrier in recent years, it is limited by the body area and the display itself. Only a small part of the content can be displayed very compactly. Users may not be able to view multiple key information at the same time, such as the current temperature, remaining time, cooking mode, etc. This limitation on information display may cause users to frequently check and adjust the oven settings during the cooking process, thus affecting the continuity and convenience of cooking.

[0003] With the increase in functions and modes of modern oven electronic products, the amount of operating information has greatly increased. The original small LCD screen can no longer fully reflect the high-end operation of the oven. The traditional oven door is just a simple heat-insulating and protective material. In some existing technologies, the oven door is set to a transparent material to facilitate consumers to observe the changes in food in the oven, but the different functions of the oven cannot be realized by touching the oven door, and the user's demand for intelligent settings of oven functions cannot be met. Utility Model Content

[0004] To solve the above problems, the utility model provides a transparent display and touch control structure for an oven door, which directly displays the operating application information of the oven on the oven door. The oven door is designed as a touch transparent display screen, which improves the continuity and convenience of cooking and meets the user's demand for intelligent settings of oven functions.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A transparent display and touch control structure for an oven door, comprising a surface ITO glass substrate and a bottom ITO glass substrate;

[0007] A touch screen ITO electrode is disposed on a side of the surface ITO glass substrate away from the bottom ITO glass substrate, and the surface ITO glass substrate is connected to the FPC of the touch screen;

[0009] Preferably, it further comprises an upper PI alignment film and a lower PI alignment film, wherein the upper PI alignment film is connected to the surface ITO segmented electrode, and the lower PI alignment film is connected to the bottom ITO common electrode.

[0010] Preferably, it further comprises a polymer network liquid crystal layer, and the polymer network liquid crystal layer is arranged between the upper PI alignment film and the lower PI alignment film.

[0011] Preferably, the surface ITO glass substrate is arranged between the touch screen ITO electrode and the upper PI alignment film, and the bottom ITO glass substrate is arranged on the side of the lower PI alignment film away from the polymer network liquid crystal layer.

[0012] Preferably, it further comprises a plastic ball, wherein the plastic ball is arranged between the upper PI alignment film and the lower PI alignment film, and the plastic ball core powder is arranged in the plastic ball.

[0013] Preferably, the surface ITO glass substrate and the bottom ITO glass substrate are connected by frame glue.

[0014] Preferably, the thickness of the polymer network liquid crystal layer is 4.0 um-7.0 um.

[0015] Preferably, the top and bottom of the surface ITO glass substrate are both provided with ITO films.

[0016] Preferably, the frame glue is provided with plastic ball glue edge powder.

[0017] Preferably, the surface ITO glass substrate and the bottom ITO glass substrate are arranged on a transparent display screen, and a bonding cover plate is provided on the surface of the ITO electrode of the touch screen.

[0018] The beneficial effects of the utility model are:

[0019] 1. The utility model includes a surface ITO glass substrate and a bottom ITO glass substrate. The back surface of the surface ITO glass substrate is provided with a touch screen ITO electrode. The back surface of the surface ITO glass substrate is connected to the FPC of the touch screen. The surface touch function can be realized through this structure. Compared with the operating interface of the traditional oven which is still mainly developed with mechanical buttons or knobs, the utility model improves the convenience of cooking.

[0020] 2. The utility model includes a surface ITO glass substrate and a bottom ITO glass substrate. The front of the surface ITO glass substrate is provided with a surface ITO segmented electrode, and the bottom ITO glass substrate is provided with a bottom ITO common electrode. The wiring of the surface ITO glass substrate and the wiring of the bottom ITO glass substrate are both connected to the IC.

[0021] The electric field generated by the surface ITO segmented electrode and the bottom ITO common electrode is used to drive the liquid crystal to twist, so as to achieve the light transmission effect, thereby realizing the display function.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 2 As shown, the utility model relates to a transparent display and touch control structure used on an oven door.

[0029] A transparent display and touch control structure for an oven door, comprising a surface ITO glass substrate 2 and a bottom ITO glass substrate 10;

[0030] A touch screen ITO electrode 1 is disposed on one side of the surface ITO glass substrate 2 away from the bottom ITO glass substrate 10, and the reverse side of the surface ITO glass substrate 2 is connected to the FPC 12 of the touch screen;

[0031] A surface ITO segmented electrode 3 is provided on the side of the surface ITO glass substrate 2 close to the bottom ITO glass substrate 10, and a bottom ITO common electrode 9 is provided on the side of the bottom ITO glass substrate 10 close to the surface ITO glass substrate 2. The wiring of the surface ITO glass substrate 2 and the wiring of the bottom ITO glass substrate 10 are both connected to the IC.

[0032] In addition to the surface ITO glass substrate 2 and the bottom ITO glass substrate 10, it also includes an upper PI alignment film 4 and a lower PI alignment film 8. The upper PI alignment film 4 is connected to the surface ITO segmented electrode 3 of the surface ITO glass substrate 2, and the lower PI alignment film 8 is connected to the bottom ITO common electrode 9 of the bottom ITO glass substrate 10. The surface ITO glass substrate 2 and the bottom ITO glass substrate 10 are bonded by frame glue 5 to form a space in an empty box state. Plastic ball edge powder is provided on the frame glue 5. A closed space is formed by pouring polymer network liquid crystal into the space in the empty box state and then curing it with sealing glue. The plastic ball 6 edge powder is used to support the edge height.

[0033] The polymer network liquid crystal material is a reverse material. After being poured into the liquid crystal empty box, it needs to pass through a light with a wavelength of 365nm and a light intensity of 116mW / cm 2 The polymer network liquid crystal is cured by ultraviolet light curing for 120 seconds.

[0034] After the polymer network liquid crystal material is cured by the UV light, if an AC voltage is applied between the segment electrode and the common electrode, it will be atomized and displayed as milky white fonts. When no voltage is applied, it is in a transparent state. The oven of the present application has a better display effect when the voltage is 5V-30V. Figure 2 As shown, Figure 2 It is the reference for the test data of driving AC voltage and transmittance / haze.

[0035] The polymer network liquid crystal layer 7 is arranged between the upper PI alignment film 4 connected to the segmented electrode and the lower PI alignment film 8 connected to the common electrode, and the box thickness height is supported by the plastic ball 6. The plastic ball 6 is provided with a center powder, which plays the role of filling and increasing the weight of the ball, and also affects the performance, durability and stability of the ball.

[0036] The cell thickness d of the polymer network liquid crystal is selected to be 4.0um-7.0um; the PI alignment film material used to make the empty cell is a PI alignment film raw material in VA (vertical orientation) mode, and the film suitable for this material has the following advantages:

[0037] Wide viewing angle: The VA mode design allows the liquid crystal molecules to maintain a good alignment at different angles, thus achieving a wider viewing angle. This means that no matter which direction the audience views the display, they can get a relatively consistent and clear image effect, which is very suitable for occasions where multiple people share viewing.

[0038] Good color reproduction: Due to the precise control of liquid crystal molecules by the VA mode, the scattering and distortion of light during transmission can be reduced, thereby better restoring the color of the image. This makes the VA mode PI alignment film have better performance when displaying colorful images.

[0039] Fast response speed: VA mode liquid crystal molecules can quickly change their arrangement direction under the action of the electric field, thus achieving a faster response speed. This helps to reduce display delay and improve the display effect of dynamic images, especially when displaying high-speed motion scenes.

[0040] Good weather resistance: The PI alignment film material itself has high stability and weather resistance, and can maintain stable performance under different environmental conditions. This makes the VA mode PI alignment film adaptable to various application scenarios, including outdoor use or harsh environments such as high temperature and high humidity.

[0041] The surface ITO glass substrate 2 is a double-sided ITO glass substrate 2. A touch screen ITO electrode 1 is provided on the reverse side of the surface ITO glass substrate 2 and connected to the FPC 12 of the touch screen, and finally connected to the interface of the whole machine. The ITO film on the side of the surface glass substrate 2 close to the touch screen is used as a sensor, that is, a sensor, which generates changes in current and capacitance through the touch screen ITO electrode 1 to locate the position of the touch point, so as to realize the surface touch function.

[0042] The surface ITO glass substrate 2 is provided with a surface ITO segmented electrode 3 and wiring on the front; the bottom ITO glass substrate 10 is provided with a bottom ITO common electrode 9 and wiring, and the wiring of the surface ITO segmented electrode 3 of the surface ITO glass substrate 2 and the bottom ITO common electrode 9 of the bottom ITO glass substrate 10 are connected to the transparent display driver IC11 position. After the transparent display driver IC11 and FPC12 are bound at this position, they are finally connected to the interface of the whole machine to realize the display function.

[0043] The upper PI alignment film 4 is provided with a surface ITO segmented electrode 3, a surface ITO glass substrate 2 is provided between the ITO segmented electrode and the wiring 1 and the upper PI alignment film 4, and a bottom ITO glass substrate 10 is provided on the side of the lower PI alignment film 8 away from the polymer network liquid crystal layer 7.

[0044] Since the ITO conductive film is coated on both sides of the surface glass substrate 2, the surface ITO glass substrate 2 has double-sided conductivity, which makes it very widely used in applications requiring double-sided touch or double-sided conductivity. The ITO conductive film is very thin and has little effect on the transmittance of light, so the surface ITO glass substrate 2 can maintain a high transparency and is suitable for touch screens and display screens.

[0045] The display of the utility model is a transparent display. The electric field generated by the surface ITO segmented electrode and the bottom ITO common electrode drives the liquid crystal to twist to achieve the light transmission effect. The transparent display without polarizer can be realized without the bonding of the surface polarizer and the bottom polarizer. The transparent display technology without polarizer, by getting rid of the constraints of the surface polarizer and the bottom polarizer in the traditional display technology, reduces the loss of light when passing through the display panel due to the removal of the polarizer, so that more light can penetrate the panel, thereby achieving a higher light transmittance. This not only enhances the brightness and clarity of the display, but also allows the transparent display screen to present brighter and more vivid colors while maintaining high transparency (such as 55% to 93%).

[0046] Secondly, the polarizer-free technology helps reduce panel power consumption. Due to the reduction of light absorption and reflection in the polarizer, the panel power consumption can be significantly reduced, about 20%. This not only helps to extend the service life of the equipment, but also conforms to the current social development trend of energy conservation and environmental protection.

[0047] The surface ITO glass substrate 2 and the bottom ITO glass substrate 10 are arranged on a transparent display screen, the interior of the transparent display screen is provided with heat-insulating glass, and the surface of the touch screen ITO electrode 1 is provided with a bonding cover plate 13. The main function of the inner layer of heat-insulating glass heat protection is to prevent the high temperature inside the oven from being directly transmitted to the oven shell, ensuring that the oven shell will not overheat, thereby protecting the user from being injured by contacting the oven shell during use. At the same time, the heat-insulating glass can also effectively reduce heat loss and improve the energy efficiency of the oven.

[0048] The outer layer of the cover plate 13 is mainly used to protect the appearance of the oven and extend its service life. The cover plate can resist external damage such as scratches and collisions, and prevent the oven shell from being damaged or deformed. In addition, the cover plate can also enhance the overall aesthetics of the oven and improve the user experience.

[0049] The combined effect of these two protective measures makes the oven both safe and durable, able to meet the user's needs for long-term, high-frequency use.

[0050] Example 2

[0051] Based on the above-mentioned embodiment 1, the design principle of the present application can be obtained. The present solution is to design the original pure oven door into a transparent display screen with touch function by using transparent display technology. The double-sided ITO of the surface ITO glass substrate 2 adopts a double-sided design, and the reverse side of the surface ITO glass substrate is made into an On-ce ll touch electrode, which corresponds to the position of the segment electrode of the positive display of the surface glass in the box, and the touch electrode is connected to the whole machine through FPC12, and the coordinates and touch signals are recognized by the transparent display driver IC11, and the display control of the segment electrode in the box is realized by the transparent display driver IC11 control circuit, so that the oven door directly becomes a transparent display touch screen, and the display touch screen has a large area and convenient touch control.

[0052] On-cell technology helps to achieve thinner and lighter panels by integrating the original external touch panel components with the LCD panel. In addition, since the physical space between the external touch panel components and the LCD panel is eliminated, the phenomenon of reduced visibility in bright environments such as outdoors is suppressed. In terms of image quality, On-cell technology does not reduce the effective display area within the pixel, so image quality degradation will hardly occur.

[0053] In this application, the FPC12 of the touch screen and the FPC12 of the transparent display are designed on one FPC12, which can significantly reduce the complexity of wiring. Traditionally, these two components may require independent FPC12 for connection, which not only increases the production cost, but also may lead to an increase in the overall volume and weight of the system. The integrated design can simplify the wiring process, reduce the number of required connectors, and thus simplify the overall design.

[0054] Sharing FPC12 can significantly reduce the space occupied by the circuit board inside the device. This is especially important for modern electronic devices that pursue thin and light designs, and helps to achieve more compact and lighter product designs.

[0055] The integrated FPC12 design helps reduce potential failure points due to multiple connection points. Reducing connectors and wiring can reduce the risk of system failures due to problems such as poor contact, looseness or damage, thereby improving the reliability of the entire system.

[0056] The integrated FPC12 design helps reduce production costs by reducing the number of components required and simplifying the production process. In addition, the complexity and error rate in the production process are reduced by reducing the number of wiring and connectors, further improving production efficiency.

[0057] The integrated FPC12 design makes the connection between the touch screen and the transparent display more compact and stable, which helps simplify the maintenance and upgrade process. When these components need to be replaced or upgraded, only one FPC12 needs to be dealt with instead of multiple independent connections, thus simplifying maintenance operations.

[0058] The transparent display screen of the present application is driven by a static AC power of 10V-11V. Low AC power means that the transparent display screen consumes less power during operation, which helps to reduce overall energy consumption and meets the environmental protection requirements of energy conservation and emission reduction. At the same time, low energy consumption also means less heat generation, which helps to extend the service life of the device.

[0059] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
