Description

Technical Field

[0001] The utility model relates to an OLED screen, more specifically, to a heating component for an OLED screen. Background Art

[0002] OLED displays are widely used in mobile phones, televisions, and other modern display devices due to their excellent display performance. However, when using OLED displays in cold environments or cold regions, users often experience slow screen response and reduced display performance. This is because semiconductor components such as the display's driver chips and TFT thin-film transistors experience significant performance degradation or even malfunction in low-temperature environments (-30°C and below), resulting in display screens not displaying properly and limiting the display's applicable environments.

[0003] Chinese invention patent document CN111552330A discloses a screen heating control method for terminal startup, comprising: S1, real-time monitoring of the temperature of multiple different positions on the screen to obtain multiple real-time temperature values; S2, calculating a median temperature value among the multiple real-time temperature values ​​and obtaining the difference between the multiple real-time temperature values ​​and the median temperature value; S3, selecting real-time temperature values ​​whose difference satisfies a preset condition as valid temperature values ​​and obtaining the average value of all valid temperature values; S4, comparing the average value with a preset target value, and executing step S5 if the average value is less than the preset target value, and executing step S6 if the average value is greater than or equal to the preset target value; S5, starting a screen heating system, and obtaining the difference between the average value and the preset target value and the change in the average value at a preset period, so as to control the heating power of the screen heating system according to the difference and the change, and executing step S1; S6, starting the terminal startup process. The multiple real-time temperature values ​​include an odd number of real-time temperature values.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0027] As described in the background, OLED displays are widely used in mobile phones, televisions, and other modern display devices due to their excellent display performance. However, when using OLED displays in cold environments or cold regions, users often encounter problems such as slow screen response and decreased display performance. This is because the display's driver chips and semiconductor material components, such as TFT thin-film transistors, experience significant performance degradation or even malfunction in low-temperature environments (-30°C and below), resulting in the display screen not displaying properly and limiting the display's applicable environments.

[0028] To solve this technical problem, the present invention provides a heating assembly for an OLED screen, comprising a first insulating layer 1, a heating layer 2 provided on the lower surface of the first insulating layer 1, a second insulating layer 3 provided on the lower surface of the heating layer 2, a substrate body 4 provided on the lower surface of the second insulating layer 3, a drive circuit layer 5 provided on the lower surface of the substrate body 4, a pixel layer 6 provided on the lower surface of the drive circuit layer 5, and an encapsulation layer 7 provided on the lower surface of the pixel layer 6. The first insulating layer 1 and the second insulating layer 3 completely cover the heating layer 2, and the second insulating layer 3 is adhered to the back of the OLED screen. The heating assembly for the OLED screen also includes a temperature sensor that monitors the ambient temperature.

[0029] Through the above structural design, when the host side recognizes that the sensor temperature reaches or exceeds its set threshold, it will start the operation of heating layer 2 and output current. By controlling the magnitude of the output current, its heating power is adjusted to achieve precise control of the screen temperature. After a period of heating, the host side will regularly obtain the temperature feedback data from the temperature sensor and adjust the magnitude of the output current to ensure that the screen operates at the appropriate temperature, thereby saving power. This heating component for OLED screens not only maintains the original advantages of OLED display technology, but also provides advantages that traditional OLEDs do not have, allowing the device to operate reliably even in extreme climate conditions, better meeting environmental protection and energy efficiency requirements, and is highly practical.

[0030] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0033] like Figure 1 and Figure 2 As shown, the heating assembly for an OLED screen includes a first insulating layer 1, a heating layer 2 is provided on the lower surface of the first insulating layer 1, a second insulating layer 3 is provided on the lower surface of the heating layer 2, a substrate body 4 is provided on the lower surface of the second insulating layer 3, a driving circuit layer 5 is provided on the lower surface of the substrate body 4, a pixel layer 6 is provided on the lower surface of the driving circuit layer 5, and an encapsulation layer 7 is provided on the lower surface of the pixel layer 6. The first insulating layer 1 and the second insulating layer 3 completely cover the heating layer 2, and the second insulating layer 3 is bonded to the back of the OLED screen. The heating assembly for an OLED screen also includes a temperature sensor, which monitors the ambient temperature.

[0034] It should be noted that the first insulating layer 1 and the second insulating layer 3 are both made of metal oxides. In addition, the first insulating layer 1 and the second insulating layer 3 have the same thickness.

[0035] The heating layer 2 is a metal resistance wire. Alternatively, the heating layer 2 is made of conductive ink. In this case, the heating layer 2 is a printed structure.

[0036] In addition, the thickness of the conductive ink is 20 micrometers to 40 micrometers. Preferably, the thickness of the conductive ink is 30 micrometers.

[0037] The working mode of this embodiment is described below.

[0038] The heating layer 2 is placed on the non-display surface of the OLED display, i.e., the back surface. The front and back surfaces of the heating layer 2 are covered by a first insulating layer 1 and a second insulating layer 3 to ensure that the wiring of the heating layer 2 does not come into contact with the outside world and short-circuit. Since the heating layer 2 covers the entire back surface of the substrate, including the AA display area, the GOA wiring area, the driver chip bonding area, etc., heat can be fully and evenly conducted.

[0039] The heating layer 2 has a positive input pin and a negative output pin. The input pin and the output pin are connected to the front of the substrate body 4 from the heating layer 2 through metal vias, and a binding position is set in the chip binding area on the front of the substrate body 4. Finally, after binding the display driver chip, the input pin and the output pin of the heating layer 2 establish an electrical connection with the display driver chip through ACF binding.

[0040] During operation, when the host recognizes that the sensor temperature reaches or exceeds its set threshold, it will start the heating layer 2 and output current. By controlling the size of the output current, the heating power is adjusted to achieve precise control of the screen temperature. After heating for a period of time, the temperature sensor's temperature return data is obtained at regular intervals. The host will adjust the size of the output current to ensure that the screen works at the appropriate temperature to save power consumption.

[0041] This heating component for OLED screens not only maintains the original advantages of OLED display technology, but also provides advantages that traditional OLEDs do not have, enabling the equipment to work reliably even in extreme climatic conditions, thereby better meeting environmental protection and energy efficiency requirements and having strong practicality.

[0042] The heating assembly for the OLED screen provided in Example 1 is further optimized. Specifically, the temperature sensor is arranged inside the display screen driver chip.

[0043] The working mode of this embodiment is described below.

[0044] Since the temperature sensor is arranged inside the display screen driver chip, there is no need to add an additional temperature sensor, thus saving production costs.

[0045] The heating assembly for the OLED screen provided in Example 1 or 2 is further optimized. Specifically, the edges of the first insulating layer 1 and the second insulating layer 3 are provided with a connecting section 8 , and the connecting section 8 covers the side of the heating layer 2 .

[0046] The working mode of this embodiment is described below.

[0047] By utilizing the connecting section 8 at the edge of the first insulating layer 1 and the second insulating layer 3, the side of the heating layer 2 can be completely covered and sealed, thereby avoiding short circuits at the edge of the heating layer 2 and further improving the reliability and stability of the heating assembly.
