Description

Technical Field

[0001] This utility model relates to the field of display technology, and more specifically, to an AMOLED display screen with temperature monitoring function. Background Technology

[0002] The development of smartwatches is booming, and consumers are increasingly curious about new technologies. Many manufacturers have added a lot of health monitoring functions to smart wearable watches, such as heart rate monitoring and electrocardiogram monitoring. On the other hand, human body temperature is the most basic parameter of human health, but currently smart wearable watches do not have the function of monitoring human body temperature.

[0003] Furthermore, AMOLED displays are quite sensitive to ambient temperature. When the ambient temperature is too low, the strength of the AMOLED display's glass cover may decrease, increasing its fragility upon drop. Luminous efficiency will also decrease; the electron migration rate of organic light-emitting materials decreases at low temperatures, requiring a 30% increase in current to maintain brightness, leading to color distortion, ghosting, or localized flickering. Touch response will also be delayed; the resistance of the ITO conductive film increases as temperature decreases, forcing an increase in the touch sampling rate and resulting in noticeable lag. Therefore, ensuring that AMOLED displays are kept at a suitable operating temperature is crucial. Utility Model Content

[0004] The technical problem this invention aims to solve is how to integrate temperature monitoring functionality into the display module, enabling real-time monitoring of both human body temperature and the AMOLED display's own temperature, reporting to the backend for analysis, and providing timely reminders to the wearer. This allows for more comprehensive monitoring of the wearer's health in today's popular wearable devices. When the temperature sensor detects that the AMOLED display's temperature is too low, it can activate the ITO heating circuit pattern to heat the entire screen, bringing the AMOLED display back to a suitable operating temperature. This prevents a decrease in the strength of the AMOLED display's glass cover, avoids a reduction in luminous efficiency, prevents touch response delays, and prevents malfunctions caused by excessively low temperatures.

[0005] The technical problem to be solved by this utility model is achieved through the following technical solution:

[0006] To address the aforementioned technical problems, this utility model provides an AMOLED display screen with temperature monitoring function, comprising an AMOLED display module and a cover plate. A teardrop notch is provided at the center of the top of the AMOLED display module located in the non-AA area. A transparent hole is provided on the lower surface of the cover plate, the position of which corresponds to the position of the teardrop notch. A temperature sensor is provided at the transparent hole and extends into the teardrop notch. An ITO heating circuit pattern is provided on the lower surface of the cover plate and / or on the AMOLED display module.

[0007] In a preferred embodiment of the AMOLED display with temperature monitoring function provided by this utility model, the temperature sensor is a non-contact temperature sensor.

[0008] As a preferred embodiment of the AMOLED display with temperature monitoring function provided by this utility model, the AMOLED display module includes foam, lower substrate, upper substrate and upper polarizer stacked sequentially from bottom to top. The lower substrate is longer than the upper substrate and extends outward to form a step. A display FPC is bonded to the upper surface of the lower substrate located at the step, and a driver IC is bonded to the display FPC.

[0009] In a preferred embodiment of the AMOLED display with temperature monitoring function provided by this utility model, the ITO heating circuit pattern is disposed on the lower surface of the lower substrate.

[0010] In a preferred embodiment of the AMOLED display with temperature monitoring function provided by this utility model, the ITO heating circuit pattern is disposed on the upper surface of the upper substrate.

[0011] As a preferred embodiment of the AMOLED display with temperature monitoring function provided by this utility model, a touch film is provided below the cover plate, and a touch FPC is bound to one end of the touch film.

[0012] In a preferred embodiment of the AMOLED display with temperature monitoring function provided by this utility model, a groove is formed on the lower surface of the foam, and the driver IC is disposed in the groove after the FPC is bent downward.

[0013] In a preferred embodiment of the AMOLED display with temperature monitoring function provided by this utility model, the thickness of the driver IC is less than the thickness of the foam.

[0014] In a preferred embodiment of the AMOLED display with temperature monitoring function provided by this utility model, the thickness of the groove is equal to the thickness of the foam, and the thickness of the foam is 0.1mm higher than the thickness of the driver IC.

[0015] In a preferred embodiment of the AMOLED display with temperature monitoring function provided by this utility model, the distance between the groove and each side of the driver IC is 0.05mm-0.10mm.

[0016] This utility model has the following beneficial effects:

[0017] Because a temperature sensor is installed at the transparent opening, temperature monitoring functionality can be integrated into the display module. This allows for real-time monitoring of both the user's body temperature and the AMOLED display's own temperature, reporting this information to the backend for analysis and timely alerts to the wearer. This enables more comprehensive monitoring of the wearable device, which is currently popular in the consumer market. When the temperature sensor detects that the AMOLED display's temperature is too low, it can activate the ITO heating circuit pattern to heat the entire screen, bringing the AMOLED display back to a suitable operating temperature. This prevents a decrease in the strength of the AMOLED display's glass cover, avoids a reduction in luminous efficiency, prevents touch response delays, and prevents malfunctions caused by excessively low temperatures.

[0030] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] This utility model provides an AMOLED display screen with temperature monitoring function, which includes an AMOLED display module and a cover plate. A teardrop notch is provided at the middle position of the top of the AMOLED display module located in the non-AA area. A transparent hole is provided on the lower surface of the cover plate, and the position of the transparent hole corresponds to the position of the teardrop notch. A temperature sensor is provided at the transparent hole and extends into the teardrop notch. An ITO heating circuit pattern is provided on the lower surface of the cover plate and / or the AMOLED display module.

[0032] Because a temperature sensor is installed at the transparent opening, temperature monitoring functionality can be integrated into the display module. This allows for real-time monitoring of both the user's body temperature and the AMOLED display's own temperature, reporting this information to the backend for analysis and timely alerts to the wearer. This enables more comprehensive monitoring of the wearable device, which is currently popular in the consumer market. When the temperature sensor detects that the AMOLED display's temperature is too low, it can activate the ITO heating circuit pattern to heat the entire screen, bringing the AMOLED display back to a suitable operating temperature. This prevents a decrease in the strength of the AMOLED display's glass cover, avoids a reduction in luminous efficiency, prevents touch response delays, and prevents malfunctions caused by excessively low temperatures.

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. The present invention will be described in detail below with reference to the accompanying drawings and embodiments, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] Example 1, please refer to Figures 1 to 6This invention provides an AMOLED display screen with temperature monitoring function, comprising an AMOLED display module 1 and a cover plate 2. A waterdrop notch 11 is provided at the middle position of the top of the AMOLED display module 1 in the non-AA area. A transparent hole 21 is provided on the lower surface of the cover plate 2, and the position of the transparent hole 21 corresponds to the position of the waterdrop notch 11. A temperature sensor 3 is provided at the transparent hole 21 and extends into the waterdrop notch 11. An ITO heating circuit pattern is provided on the lower surface of the cover plate 2 and / or on the AMOLED display module 1. That is, an ITO heating circuit pattern is provided on the lower surface of the cover plate 2, or an ITO heating circuit pattern is provided on the AMOLED display module 1, or both the lower surface of the cover plate 2 and the AMOLED display module 1 are provided with ITO heating circuit patterns. Because a temperature sensor 3 is installed at the transparent hole 21, the temperature monitoring function can be integrated into the display module. It can monitor the body temperature and the temperature of the AMOLED display itself at any time, report to the background for analysis, and promptly remind the wearer. This can be applied to wearable devices that are currently popular in the consumer market, making the monitoring of the wearer's health more comprehensive. When the temperature sensor 3 detects that the temperature of the AMOLED display itself is too low, it can activate the ITO heating circuit pattern to heat the entire screen, so that the AMOLED display returns to a suitable operating temperature. This prevents the strength of the glass cover 2 of the AMOLED display from decreasing, avoids a decrease in luminous efficiency, avoids touch response delays, and prevents the AMOLED display from malfunctioning due to low temperature.

[0035] Furthermore, the temperature sensor 3 is a non-contact temperature sensor 3. There are two temperature sensors 3, one for monitoring the wearer's temperature and the other for monitoring the AMOLED display's own temperature.

[0036] Furthermore, the AMOLED display module 1 includes foam 12, lower substrate 13, upper substrate 14 and upper polarizer 15 stacked sequentially from bottom to top. The lower substrate 13 is longer than the upper substrate 14 and extends outward to form a step. A display FPC 16 is bonded to the upper surface of the lower substrate 13 located at the step, and a driver IC 17 is bonded to the display FPC 16.

[0037] Furthermore, the ITO heating circuit pattern is disposed on the lower surface of the lower substrate 13.

[0038] Example 2, as a further optimization of Example 1, differs from Example 1 in that the ITO heating circuit pattern is set on the upper surface of the upper substrate 14.

[0039] Example 3, as a further optimization of Example 1, differs from Example 1 in that the ITO heating circuit pattern is set on the lower surface of the cover plate 2.

[0040] Example 4, as a further optimization of Example 1, differs from Example 1 in that the ITO heating circuit pattern is set on the lower surface of the cover plate 2 and the lower surface of the lower substrate 13.

[0041] Example 5, please refer to Figure 7 As a further optimization of Embodiment 1, in this embodiment, a groove 18 is formed on the lower surface of the foam 12. After the FPC is bent downwards, the driver IC 17 is placed in the groove 18, and the thickness of the driver IC 17 is less than the thickness of the foam 12. Since the thickness of the foam 12 is greater than the thickness of the driver IC 17, a groove 18 of appropriate size is formed on the foam 12 below the lower substrate 13. This groove 18 can just accommodate the driver IC 17. After the FPC is bent, the driver IC 17 can be hidden in the groove 18. At this time, the driver IC 17 can avoid interference with other components and scratches, and at the same time, it can prevent dust from entering, which is beneficial to improving the dustproof capability of the driver IC 17, avoiding driver IC 17 malfunction, and improving the competitiveness of the product.

[0042] Furthermore, the thickness of foam 12 is 0.1mm greater than the thickness of driver IC 17, and the thickness of groove 18 is equal to the thickness of foam 12, so that driver IC 17 can be smoothly hidden in groove 18 of foam 12.

[0043] Furthermore, the distance between the groove 18 and each side of the driving IC 17 is 0.05mm-0.10mm, so that the driving IC 17 can be smoothly hidden in the groove 18 of the foam 12. In this embodiment, the length of the groove 18 is 8.5mm, the width of the groove 18 is 2.2mm, the depth of the groove 18 is 0.4mm, the length of the driving IC 17 is 8.3mm, the width of the driving IC 17 is 2.06mm, and the thickness of the driving IC 17 is 0.3mm.

[0044] Furthermore, an electromagnetic shielding layer is provided on the lower surface of the driver IC17 to protect the driver IC17 from electromagnetic interference. The electromagnetic shielding layer completely covers the driver IC17 and the groove 18, so that the electromagnetic shielding layer can completely cover the groove 18, preventing dust or moisture from entering the groove 18, and better protecting the driver IC17.
