[0002] With the development of information technology, touch display modules have been widely used in consumer electronics, commercial advertising, industrial control, automotive terminals, medical equipment, and many other fields. Users' requirements for display effects are no longer limited to indoor visibility, but extend to clarity under strong outdoor light, accurate color reproduction, delicate detail presentation, and reliable touch interaction in complex industrial environments. Currently, mainstream ordinary display modules on the market typically have the following limitations: insufficient brightness, generally around 200-300 cd / m², relying on indoor ambient light. In direct sunlight or strong factory lighting conditions, the screen content will appear washed out and the contrast will decrease due to ambient light reflection and insufficient backlight brightness, making it difficult to see and limiting application scenarios. Therefore, we have made improvements and proposed a touch-enabled display module. Summary of the Invention

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] For an example, please refer to... Figures 1-6 A touch-enabled display module includes a display component 1 and a backlight component 2 disposed on the back of the display component 1; the display component 1 includes an anti-glare glass cover 101, a touch sensor 112 and an adhesive layer 113, the back of the anti-glare glass cover 101 is bonded to the touch sensor 112 through the adhesive layer 113 to form an integrated touch display surface; The backlight assembly 2 includes a backlight frame 202, a high-density LED light source, a light guide plate 204, a brightness enhancement film 205, and a light-shielding frame 206. The brightness enhancement film 205 is disposed on the light-emitting surface of the light guide plate 204. The high-density LED light source is disposed laterally or vertically to provide backlight to the light guide plate 204. The light-shielding frame 206 is connected between the touch sensor 112 and the brightness enhancement film 205 for light shielding and fixation.

[0020] With the addition of a backlight iron frame 202 and a light-shielding rubber frame 206, it features high temperature resistance, low temperature resistance, and anti-aging properties. It can adapt to complex environments such as outdoor high and low temperatures, workshop dust, and strong light in operating rooms. Its service life is longer than that of ordinary display modules, which can reduce the cost of replacement and maintenance in the later stages.

[0021] Furthermore, the backlight assembly 2 also includes a reflective film 203, which is disposed on the side of the light guide plate 204 away from the brightness enhancement film 205.

[0022] Furthermore, the high-density LED light source is connected to wires, which are led out from the backlight iron frame 202 and electrically connected to terminals 201.

[0023] Furthermore, the anti-glare glass cover 101 is glass that has undergone AG treatment or AR treatment. The outer surface of the anti-glare glass cover 101 is provided with an AF layer to achieve the functions of anti-glare, enhanced transparency and anti-fingerprint, and is suitable for touch use.

[0024] Furthermore, the high-density LED light source arrangement density, combined with the brightness enhancement film 205, ensures that the maximum brightness of the display module is not less than 500 cd / m², preferably 1500-3000 cd / m², to achieve visibility under strong outdoor light. Typically, 500-1000 cd / m² is sufficient, but for industrial and outdoor applications, it can be set to 1500-3000 cd / m², making direct sunlight visible and expanding the applicable scope of touch display scenarios.

[0025] Furthermore, display component 1 adopts a wide-viewing-angle LCD panel using IPS, ADS, or VA technology. The wide-viewing-angle LCD panel, combined with a high-purity RGB color filter and Gamma correction driver, achieves a color gamut coverage of 72%-100% sRGB, and a color accuracy ΔE < 2. By adopting an IPS / ADS / VA wide-viewing-angle panel, combined with a high-purity RGB color filter and Gamma correction driver, the color gamut coverage is wide and the color accuracy is high, effectively solving the problems of pale colors, color cast, and poor brightness and darkness levels in ordinary display modules. It can accurately reproduce skin tones, landscape colors, and design color values. Combined with touch interaction, it is suitable for touch scenarios with high color requirements, such as advertising, design, and automotive applications. The color performance and interaction capabilities of ordinary display modules cannot meet the usage standards of such scenarios. When paired with a driver IC, it supports both display driver and touch driver as well as Gamma correction circuitry, enabling precise adjustment of color levels and brightness curves to avoid color banding and uneven local brightness; it also optimizes the touch driver algorithm to reduce touch latency and accidental touches.

[0026] Furthermore, the touch sensor 112 is a capacitive or resistive touch sensor with a touch response speed of ≤5ms, supports multi-touch, and reduces signal interference. Unlike ordinary display modules, which require an additional touch module, have poor compatibility, and are cumbersome to install, this application integrates capacitive or resistive touch functionality, with a fast touch response speed of ≤5ms, high touch accuracy, and support for multi-touch, enabling precise control. The integrated design reduces installation steps, improves the overall compatibility and stability of the device, and is suitable for various scenarios that require direct touch interaction without the need for additional touch components.

[0027] The front of the anti-glare glass cover 101 is also provided with a protective film, and the protective film is provided with a first tear-off handle 102; A foam double-sided adhesive 114 is provided on the back of the anti-glare glass cover 101. A release film 105 is provided on the side of the foam double-sided adhesive 114 away from the anti-glare glass cover 101. The release film 105 is provided with a second tear-off handle 106. The foam double-sided adhesive 114 is used to install this application onto the housing of the display device during use. The release film 105 is used to protect the foam double-sided adhesive 114 before use.

[0028] Furthermore, the touch sensor 112 is bonded to the main screen FPC 107, the main screen FPC 107 has a component area 108, the component area 108 has a driver IC, and the driver IC is covered with an insulating film.

[0029] Furthermore, the end of the main screen FPC107 is equipped with an FPC gold finger 110 and a reinforcing plate 109.

[0030] Furthermore, conductive double-sided adhesive 111 is provided on the back of the main screen FPC107, which is used to bond the main screen FPC107 to the back of the backlight iron frame 202 after it is bent.

[0031] This application features high resolution, with 1080P, 2K, or 4K resolutions available, and high PPI, ensuring no loss of detail. The high resolution, combined with high-precision pixel technology, results in finer pixels and a PPI far exceeding that of ordinary display modules. Whether it's intricate drawings, medical images, small text parameters, or high-definition videos and graphic posters, it can present sharp edges and delicate textures without graininess or loss of detail. Combined with touch functionality, it can meet the needs of touch interaction scenarios with high detail requirements, such as professional design, industrial control, and medical fields. This application features a high color gamut, with a color gamut of 72%-90%+NTSC (100%sRGB), a color accuracy ΔE<2, and true color reproduction. This application can be adapted to the following scenarios: Scenario 1: Outdoor Commercial Displays: Outdoor advertising machines, bus stop signs, park information screens, and open-air information kiosks; Under direct sunlight, ordinary display modules reflect light and appear white, making it impossible to see the content. They also lack touch functionality, failing to meet outdoor interactive needs. The high brightness of this application can meet the display requirements in strong outdoor environments, the high color gamut ensures color reproduction of advertising images, the high resolution ensures the fineness of graphic and text display, and the integrated touch functionality can meet interactive needs such as outdoor querying and operation. Scenario 2: In-vehicle terminals: in-vehicle central control screen, full LCD instrument panel, HUD passenger screen, in-vehicle touch control terminal; When driving, strong sunlight shines directly through the window, making it impossible for ordinary display modules to clearly display navigation and instrument data, and they lack touch functionality, thus failing to achieve convenient in-vehicle operation. This application features high brightness and anti-glare properties, high color gamut and high resolution, as well as wide temperature resistance and sensitive touch functionality, which can meet the needs of safe display and convenient touch operation in in-vehicle scenarios. Scenario 3: Professional Design and Office Drafting: Designing touch monitors, image editing screens, industrial drafting touch consoles, and industrial control touch terminals; Designers, surveyors, and CAD operators have specific requirements for color accuracy and image detail, and need convenient touch interaction. Ordinary display modules can cause color discrepancies in the final design and loss of lines in the drawings due to color deviation, and the lack of touch functionality affects work efficiency. The high color gamut, high resolution, and high color accuracy of this application can achieve accurate presentation of colors and details, and the integrated touch functionality can improve the ease of operation and meet the needs of professional work. Scenario 4: Industrial Control & Medical Equipment: Industrial touch screen all-in-one machines, machine tool touch screen displays, medical monitor touch terminals, testing equipment touch screens, operating room touch display terminals; In environments with strong workshop lighting or operating room lighting, ordinary display modules cannot clearly display equipment parameters and medical images, and lack touch functionality, making it impossible to conveniently control the equipment. Furthermore, industrial and medical scenarios have specific requirements for the equipment's resistance to high and low temperatures, anti-interference, and service life, which ordinary display modules made with civilian-grade materials cannot meet. The high brightness, high resolution, high weather resistance, and sensitive touch functionality of this application can perfectly match the working conditions and interaction requirements of such scenarios.

[0032] Scenario 5: High-end consumption & new retail terminals: high-end laptop touch screens, tablets, gaming touch monitors, self-service cash registers, milk tea ordering machines, ATM touch terminals; High-end consumer terminals have high requirements for display quality and touch interaction. Ordinary display modules have a rough appearance, are limited in outdoor use, and lack touch functionality. New retail terminals are mostly located in bright environments such as store windows and lobbies, requiring convenient touch operation. Ordinary display modules are prone to glare and are inconvenient to operate. This application can improve the user's display experience and the convenience of touch operation.
