Description

Technical Field

[0001] This invention relates to the field of display technology, specifically to a display structure that integrates touch display through different structural combinations. Background Technology

[0002] With the development of touch technology, the integration of display panels and touch functionality has become widespread. In existing touch display modules, the traditional combination of a display panel and an external touchscreen increases the overall structural thickness, making it less suitable for devices with limited internal space. To address this thickness issue, the industry has developed ONCELL and INCELL structures. While the ONCELL structure can reduce module thickness, it has a longer production cycle and higher manufacturing costs. The INCELL structure integrates the touch functionality within the display panel, which increases the manufacturing cost of the display glass and makes the internal circuitry and touch signals prone to interference, resulting in complex and time-consuming touch signal debugging processes.

[0003] Given the above situation, how to reduce the production cycle and debugging costs while controlling the module thickness by adjusting the structural combination of each component is an urgent technical problem to be solved. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a display structure that integrates touch display into one unit through different structural combinations. This solves the problems of large space occupation by external structures and high manufacturing costs and complex signal debugging of ONCELL and INCELL structures in existing touch display modules.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a display structure integrating touch display through different structural combinations, comprising: a display screen, an external assembly of the display screen, an internal touch driving system and a display timing control board, a display driving chip fixedly connected between the display screen and the assembly, a touch sensor film disposed above the display screen, upper and lower polarization systems disposed on the display side and backlight side of the display screen, and a touch signal connection line disposed between the touch sensor film and the assembly.

[0006] Preferably, the touch driving system is integrated inside the display timing control board, and the touch driving system is fixedly connected to the display timing control board.

[0007] Preferably, the assembly is an integrated and fixed structure, the assembly is a single circuit board, and the touch driving system and the display timing control board are jointly integrated on the single circuit board.

[0008] Preferably, the upper and lower polarizing system is provided with an upper polarizer and a lower polarizer, the upper polarizer being fixedly connected to the display side of the display screen, and the lower polarizer being fixedly connected to the backlight side of the display screen.

[0009] Preferably, the touch sensor film is fixedly connected below the upper polarizer, and the touch sensor film is fixedly connected above the display screen.

[0010] Preferably, the touch sensor film is fixedly connected above the upper polarizer, and the touch sensor film is fixedly connected above the upper polarizer.

[0011] Preferably, one end of the display driver chip is fixedly connected to the edge of the display screen, the other end of the display driver chip is electrically connected to the outside of the assembly, and a flip-chip encapsulation structure is provided on the outside of the display driver chip.

[0012] Preferably, the signal output terminal of the touch sensor film is fixedly connected to one end of the touch signal connection line, and the corresponding terminal of the touch driving system is electrically connected to the other end of the touch signal connection line.

[0013] Preferably, the outermost display surface of the display structure is provided with a surface protective layer.

[0014] Preferably, the interior of the display screen is made of glass substrate or flexible substrate, and the main body of the display screen is a liquid crystal panel, an OLED panel or a microLED panel.

[0015] This invention provides a display structure that integrates a touch display through different structural combinations. It offers the following advantages: 1. This invention integrates the touch driving system and the display timing control board onto a single circuit board to form a combined unit, avoiding the traditional separate circuit board layout of touch and display. This shared board design reduces the number of control boards and eliminates the need for connecting cables between multiple components, thereby reducing the internal assembly space of the display and facilitating the thinner and lighter design of terminal electronic devices.

[0016] 2. The present invention places the touch sensor film above or below the upper polarizer, so that the touch film layer and the polarization system form a layered cooperation. This structure eliminates the thickness increase of traditional external touch screens, and does not require changes to the pixel arrangement inside the display panel. It avoids the complex processes of panel manufacturing and touch signal debugging in the INCELL structure, thereby simplifying the module assembly process.

[0017] 3. The present invention uses a display driver chip with a flip-chip thin film encapsulation structure between the display screen and the assembly, and connects it to the assembly in conjunction with touch signal connection lines. This encapsulation and wiring structure facilitates the physical fixation of the module edge and the guidance of the lines, reduces the assembly difficulty of docking the separate components, shortens the module production cycle, and thus reduces the production cost of the display.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see the appendix Figure 1 and attached Figure 2This invention provides a display structure integrating touch display through different structural combinations, including: a display screen 1, a connector 2 disposed outside the display screen 1, a touch driving system and a display timing control board disposed inside the connector 2, a display driving chip 3 fixedly connected between the display screen 1 and the connector 2, a touch sensor film 5 disposed above the display screen 1, upper and lower polarization systems 6 disposed on the display side and backlight side of the display screen 1, a touch signal connection line 4 disposed between the touch sensor film 5 and the connector 2, a touch driving system integrated inside the display timing control board, the touch driving system being fixedly connected to the display timing control board, the connector 2 being an integrated and fixed structure, the connector 2 being a single circuit board, the touch driving system and the display timing control board being jointly integrated on the single circuit board, one end of the display driving chip 3 being fixedly connected to the edge of the display screen 1, the other end of the display driving chip 3 being electrically connected to the outside of the connector 2, a flip-chip thin film encapsulation structure being disposed outside the display driving chip 3, one end of the touch signal connection line 4 being fixedly connected to the signal output end of the touch sensor film 5, and the other end of the touch driving system being electrically connected to the corresponding end of the touch signal connection line 4.

[0022] Display screen 1 is used to display images. Assembly 2 is located outside display screen 1 and houses the control hardware, providing the hardware foundation for display screen 1 to display images. The touch driving system and display timing control board are located inside assembly 2. The touch driving system receives touch electrical signals and resolves the touch coordinates. The display timing control board processes image data and outputs corresponding control signals. Display driver chip 3 is connected between display screen 1 and assembly 2, receiving data from the display timing control board and converting it into driving voltage applied to display screen 1. Touch sensor film 5 is located above display screen 1, sensing touch actions and generating touch signals. Upper and lower polarization systems 6 are located on the display side and backlight side of display screen 1, polarizing light and coordinating with the display screen 1 control system. The light transmittance is controlled by the touch signal connection line 4, which is located between the touch sensor film 5 and the assembly 2. This allows the touch signal to be transmitted to the assembly 2 for further processing. The touch driving system and the display timing control board are integrated together on the assembly 2, which is a single circuit board. This integrated structure can reduce the space occupied by the circuit board. The flip-chip encapsulation structure is located outside the display driver chip 3, which can achieve physical fixation and electrical connection, and facilitate the assembly and routing of the module edge lines. The two ends of the touch signal connection line 4 are respectively connected to the signal output end of the touch sensor film 5 and the touch driving system, which can establish a transmission loop for the touch signal. In addition, the surface protective layer 7 is located on the outermost display surface of the display structure, which can protect the internal polarization system and touch film structure.

[0023] Please see the appendix Figure 3 and attached Figure 4 The upper and lower polarization system 6 is internally provided with an upper polarizer and a lower polarizer. The upper polarizer is fixedly connected to the display side of the display screen 1, and the lower polarizer is fixedly connected to the backlight side of the display screen 1. A touch sensor film 5 is fixedly connected below the upper polarizer and above the display screen 1. The touch sensor film 5 is fixedly connected above the upper polarizer and above the upper polarizer. The outermost display surface of the display structure is provided with a surface protective layer 7.

[0024] The upper polarizer and lower polarizer are disposed inside the upper and lower polarization system 6, and can work with the display screen 1 to polarize the light. The upper polarizer is disposed on the display side of the display screen 1 and can control the polarization state of the emitted light. The lower polarizer is disposed on the backlight side of the display screen 1 and can polarize the light entering the display screen 1. The touch sensor film 5 is disposed below the upper polarizer and between the display screen 1, or above the upper polarizer, and can sense touch actions and generate corresponding touch signals to meet different module stack-up designs. In addition, the surface protective layer 7 is disposed on the outermost display surface of the display structure and can protect the internal polarization system and touch sensor film 5 from physical scratches.

[0025] Please see the appendix Figure 1 -Appendix Figure 4 The interior of display screen 1 is made of glass substrate or flexible substrate, and the main body of display screen 1 is a liquid crystal panel, OLED panel or microLED panel.

[0026] The interior of the display screen 1 uses a glass substrate or a flexible substrate. The glass substrate provides structural support for the internal circuitry and pixel structure of the display screen 1, while the flexible substrate meets the bending or deformation requirements of the module. The main body of the display screen 1 is a liquid crystal panel, an OLED panel, or a microLED panel. The liquid crystal panel displays images by controlling the deflection state of liquid crystal molecules, the OLED panel displays images using the self-emissive properties of organic light-emitting diodes, and the microLED panel displays images using a micron-level array of light-emitting diodes. The combination of the above different substrates and panels is used to adapt to display products of different sizes, such as small, medium, and large.

[0027] Working Principle: During operation, the integrated assembly 2, mounted on a single circuit board, handles overall signal processing. During display, the display timing control board within assembly 2 processes image signals and transmits the driving voltage to the display screen 1 via a display driver chip 3 encapsulated with a flip-chip film. Light sequentially passes through the upper and lower polarization systems 6 and the surface protective layer 7 to complete image display. During touch operation, when a user touches the screen, the touch sensor film 5, positioned above or below the upper polarizer, senses the touch action and generates a touch signal. This signal is transmitted back to the integrated touch driver system within assembly 2 via the touch signal connection line 4 for coordinate analysis. By integrating the touch film into the polarizer stack structure and sharing the same substrate for touch and display driving, the increased thickness of traditional external touchscreens is reduced, and the complex internal debugging required by INCELL structures is avoided, thereby reducing assembly space, simplifying the assembly process, and lowering production costs.
