DETAILED DESCRIPTION

[0024] The ultra-thin bendable touch display module of the utility model includes a silk screen panel 1 with a touch cable, a light guide plate 2, a reflective film 3, and an FPC 4 from top to bottom. A light-blocking outer frame 5 is arranged around the light guide plate and the reflective film between the silk screen panel and the FPC. A side-emitting LED 6 located on the side of the light guide plate is arranged on the FPC. In order to cooperate with customers to obtain better design solutions and more utilization space, the display mode of the light guide plate plus the side-emitting LED is adopted to replace the current display mode of emitting light through the lower LED on the market, and the FPC is used to replace the commonly used hard PCB board to greatly reduce the height of the overall display module and achieve an ultra-thin size (the total thickness of the display module is 1.1±0.2mm). White light-blocking silicone is used to replace the PPO / PC plastic material of the ordinary display module to achieve the light-blocking requirements and enable the entire display module to achieve a bendable effect. By adjusting the display mode, structural design, and overall combination mode, the ultra-thin and bendable effect is achieved to meet the market and customer needs and respond to different scene requirements.

[0025] In order to facilitate quick and accurate installation, FPC4 is provided with LED application position markings 7 and light-blocking outer frame application position markings 8, and the side-emitting LED and light-blocking outer frame and LED application position markings and light-blocking outer frame application position markings set on FPC correspond to each other one by one. In order to further control the thickness, FPC4 is provided with FPC sockets 8 with FPC as the carrier and wire pads 9 connected to the external structure. FPC is used to replace the commonly used hard PCB board to greatly reduce the height of the overall display module and achieve ultra-thin size; FPC is used as the carrier of LED and touch socket, and LED application position markings are preset on FPC.

[0026] In order to reasonably layout and install the side-emitting LED, a display mode of a light guide plate plus a side-emitting LED is adopted to replace the current display mode of emitting light through the bottom LED on the market. The side-emitting light and the light guide plate cooperate with the light emission mode. At least one accommodating cavity 11 for placing the light guide plate 2 and the reflective film 3 is provided on the light-blocking outer frame 5. The light-blocking outer frame and the light guide plate are respectively provided with an upper half groove 12 and a lower half groove 13. The upper half groove and the lower half groove form a mounting hole 14 for placing the side-emitting LED. The shape of the light guide plate is consistent with the shape of the accommodating cavity. The light-blocking outer frame and the light guide plate are respectively provided with an upper half groove and a lower half groove, or a plurality of upper half grooves and a plurality of lower half grooves are intermittently distributed.

[0027] The light-blocking outer frame 5 is a white light-blocking silicone outer frame, which uses white light-blocking silicone to replace the PPO / PC plastic material of the ordinary display module to achieve the light-blocking requirement, and uses an ultra-thin light guide plate to achieve a uniform light guide effect, and enables the entire display module to achieve a bendable effect.

[0028] The silk-screen panel of the utility model is a color touch silk-screen panel. The thickness of the light-blocking outer frame 5 is greater than or equal to the thickness of the light guide plate 2 and the reflective film 3, and the side-emitting LED 6 is equal to or less than the thickness of the light-blocking outer frame 5. The thickness of the ultra-thin bendable touch display module is 1.1±0.2mm. Ultra-thin, flexible and bendable materials are used throughout to achieve the bendable effect of the entire module; by adjusting the shape of the light guide plate, the control of the thickness of the LED and the distance between the panel and the FPC, and the thickness control of the reflective film, the light guide plate and the white silicone outer frame, better display effects and overall thickness control can be achieved.
