Novel in-screen punching and touch integrated module

Abstract

The invention relates to the technical field of display screens, and discloses a novel in-screen punching and touch integrated module which comprises a glass cover plate, an LCD display screen is fixedly installed at the bottom of the glass cover plate, a light guide plate capable of guiding light is fixedly installed at the bottom of the LCD display screen, a backlight plate is fixedly installed at the bottom of the light guide plate, and an LED lamp set is arranged at the left end of the backlight plate. According to the novel in-screen punching and touch control integrated module, the lamp beads are installed above the conductive plate, the limiting cover plate is installed on the inner side of the installation plate, so that the limiting cones on the limiting plate are attached to the outer sides of the lamp beads, and therefore the lamp beads are subjected to limiting treatment; therefore, in the using process, the situation that the lamp bead or the glass lens vibrates and shakes due to limitation of the spring is reduced, the distance change between the lamp bead and the glass lens in the using process is reduced, and the situation that the light intensity changes in the using process is reduced.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a novel in-screen perforated touch integrated module. Background technique [0002] LCM (LCDModule) is LCD display module and liquid crystal module, which refers to the assembly of liquid crystal display devices, connectors, peripheral circuits such as control and drive, PCB circuit boards, backlight sources, structural parts, etc.; LCM liquid crystal display is based on Its image is clear and delicate, no flicker, no eye injury, no radiation, low power consumption, lighter and thinner, etc. It replaces the traditional CRT cathode ray tube display, and is favored by consumers. As the touch technology of smart electronic products becomes more and more mature, more and more products related to LCD display modules are used in people's lives, and the application of LCM modules is becoming more and more extensive; [0003] A Chinese patent on a new type of in-screen perforate...

Problems solved by technology

[0003] A Chinese patent on a new type of in-screen perforated touch integrated module (application number CN201921573518.9) mentions that "the LED light groups on the existing in-screen perforated touch module are all placed on the backlight board, but The installation of the LED lamp group on this module is unstable, and it is easy to explode the lamp when vibration occurs, resulting in damage to the lamp bead. Moreover, the existing LED lamp group has poor heat dissipation performance, and the heat generated by the lamp bead will damage the lamp bead. It will affect the life of the lamp bead and reduce the life of the lamp bead", and in this patent, "by setting an elastic convex plate and a compression spring in the LED lamp group, the elastic convex plate and the compression spring can be used to install the lamp bead stably, and at the same time The lamp bead plays the role of cushioning and protection.” However, when the spring is used for buffering work, the spring itself is relatively elastic, and it is easy to vibrate due to external force during use, which will cause the distance between the glass lens and the lamp bead to change, resulting in the use process. Changes in light intensity will seriously affect the use effect. Therefore, we propose a new type of in-screen perforated touch integrated module
