[0032] Embodiment 1 of the laptop computer touch panel of the utility model

[0033] like Figure 1-Figure 2 As shown, the laptop computer touch panel of the utility model comprises: a transparent display cover plate 1 and a touch sensor structure 2, wherein the transparent display cover plate 1 is used to protect the touch sensor structure 2 to reduce the damage of the touch sensor structure 2, and the touch sensor structure 2 is used for the user to touch with his hand and write with a pen-like tool;

[0034] A touch sensor is a sensor used to detect and respond to touch input. It is commonly used in various electronic devices such as smartphones, tablets, laptops, game controllers, etc. The working principle of a touch sensor is usually to detect electrical changes caused by touch. When a user touches it, the electrical characteristics of the sensor will be changed, thereby triggering the sensor and generating a signal. This signal can be converted into instructions that a computer can understand, thereby controlling the operation of the electronic device. Common types of touch sensors include resistive, capacitive, and optical. Among them, resistive touch sensors work by measuring the change in resistance caused by touch, while capacitive touch sensors work by measuring the change in capacitance caused by touch. Optical touch sensors work by measuring the change in light passing through the touch point.

[0035] Further, such as Figure 1As shown, a display unit is provided on one side of the touch sensor structure 2 away from the transparent display cover 1, and the display unit is used to display the writing picture of the touch sensor structure 2, that is, when the user inputs handwriting, the display unit can synchronously display the handwriting content, thereby facilitating user recognition;

[0036] The use of a transparent display cover 1 can effectively reduce damage to the touch sensor structure 2, such as scratches, stains, etc. The setting of the touch sensor structure 2 can make the overall appearance more neat and beautiful; the use of a transparent display cover 1 can reduce direct contact with the touch sensor structure 2, and dirt such as stains and fingerprints will not directly adhere to the screen, making it easy to clean.

[0037] Embodiment 2 of the laptop computer touch panel of the utility model

[0038] like Figure 1 As shown, the laptop computer touch panel of the present invention further comprises a connecting member in the display part, and the connecting member is arranged on a side of the touch sensor structure 2 away from the transparent display cover 1, and the connecting member is used to connect the touch sensor structure 2 and the display member together.

[0039] Further, such as Figure 1 As shown, the display unit also includes a display element, which is arranged on a side of the connecting member away from the touch sensor structure 2. The display element is used to display the writing picture of the touch sensor structure 2, that is, when the user inputs handwriting, the display element can synchronously display the handwritten content, thereby facilitating user recognition.

[0040] Further, such as Figure 1 As shown, the display part further includes a light source component, which is arranged on a surface of the display component away from the connecting component, and is used to provide the required light source for the display component.

[0041] Embodiment 3 of the laptop computer touch panel of the utility model

[0042] like Figure 1 As shown, the laptop computer touch panel of the utility model further has a connecting member which is a connecting adhesive layer 3, the connecting adhesive layer 3 is fixedly connected to a side of the touch sensor structure 2 away from the transparent display cover 1, and the connecting adhesive layer 3 is OCA adhesive or OCR adhesive;

[0043] OCA is a colorless and transparent special double-sided adhesive with a light transmittance of more than 90%. It belongs to the category of pressure-sensitive adhesive. It is mainly used to bond transparent optical components, such as lenses, etc. It is required to have the characteristics of colorless and transparent, light transmittance of more than 95%, good bonding strength, curing at room temperature or medium temperature, and small curing shrinkage. The advantages of OCA glue include high cleanliness, high light transmittance, low haze, uniform thickness of the glue layer, high flatness, high adhesion, and high bonding strength after bonding. It can be used for soft-to-soft and soft-to-hard bonding, with controlled thickness, uniform spacing, good durability, no yellowing, no stratification or degradation, etc. OCA glue is widely used in touch screens, solar cells, optical lenses and other fields;

[0044] OCR is a high-transparency resin material used for optical components, also known as optical resin or transparent resin; it is mainly used to manufacture optical components such as lenses, windows, etc., and requires high transparency, low haze, high refractive index and other characteristics; the advantages of OCR glue include high light transmittance, low refractive index, low water absorption, low shrinkage, etc.; it usually exists in liquid form and needs to be cured under ultraviolet light. OCR glue is widely used in various optical instruments, cameras, glasses and other fields.

[0045] Further, such as Figure 1 As shown, the display element is a TFT liquid crystal display panel structure 4, and the TFT liquid crystal display panel structure 4 is fixedly connected to a side of the connecting adhesive layer 3 away from the touch sensor structure 2;

[0046] TFT liquid crystal display panel is an active matrix liquid crystal display technology, which uses thin film transistors as switching elements, and each pixel is controlled by a thin film transistor; TFT liquid crystal display panel is characterized by high speed, high brightness, high contrast, and can be used for large-size and high-resolution display screens. TFT liquid crystal display panel is mainly used in high-end products, such as laptops, desktop computer monitors, LCD TVs, etc.; the main components of TFT liquid crystal display panel include fluorescent tubes, light guide plates, polarizing plates, filters, glass substrates, alignment films, liquid crystal materials, thin film transistors, etc.; its working principle is to control the deflection angle of liquid crystal molecules through thin film transistors, thereby realizing changes in brightness and darkness, thereby displaying images; compared with traditional passive matrix liquid crystal display technology, TFT liquid crystal display panel has higher response speed and lower power consumption.

[0047] Further, such as Figure 1 As shown, the light source is a BLU backlight assembly 5, and the BLU backlight assembly 5 is fixedly connected to a surface of the TFT liquid crystal display panel structure 4 away from the connecting adhesive layer 3;

[0048] The luminous effect of the BLU backlight will directly affect the visual effect of the TFT liquid crystal display panel structure 4. The TFT liquid crystal display panel structure 4 itself does not emit light. It displays graphics or characters as a result of its modulation of light. The BLU backlight is an important accessory of the transmissive liquid crystal. The main indicators of the TFT liquid crystal display panel structure 4, such as brightness, color, and power consumption, are heavily dependent on the performance of the back BLU backlight component 5. The BLU backlight component 5 is usually composed of a lamp tube, a light guide plate, a reflective plate, and a diffuser. The lamp tube emits light, and the light guide plate is responsible for evenly distributing the light to the surface of the TFT liquid crystal display panel structure 4. The function of the reflective plate is to reflect the light back to the light guide plate to improve the utilization rate of the light, and the function of the diffuser is to make the light more evenly distributed on the surface of the TFT liquid crystal display panel structure 4.

[0049] Further, such as Figure 1 As shown, the connecting adhesive layer 3 is used to realize the connection between the TFT liquid crystal display panel structure 4 and the touch sensor structure 2 , and the BLU backlight assembly 5 is used to provide the required light source for the TFT liquid crystal display panel structure 4 .

[0050] Further, such as Figure 1 As shown, the touch sensor structure 2, the TFT liquid crystal display panel structure 4 and the BLU backlight assembly 5 are all connected to the mainboard of the notebook computer, so that the content written by the touch sensor structure 2 can be transmitted to the mainboard, and the mainboard can control the TFT liquid crystal display panel structure 4 to display the written content.
