In an embodiment, a metal trace at the boundary between the second display area and the electronic component area is made of a transparent material. For the metal trace disposed around the boundary between the second display area and the electronic component area, the transparent material is used to fabricate the metal trace, so that the electronic component area can normally transmit light, without impacting a normal operation of the electronic component area.
In an embodiment, the liquid crystal display panel includes a display area, wherein the display area includes a first metal layer, and material of the first metal layer is a transparent material. By setting the material of the first metal trace as a transparent material, the metal trace disposed around the boundary between the display area and the electronic component area is made of a transparent material, such that the first metal trace does not impact transmission of the electronic component area, and the electronic component area can normally transmit light.
In an embodiment, the liquid crystal display panel includes a display area, wherein the display area includes a second metal layer and an insulating layer, and the insulating layer is disposed between the first metal layer and the second metal layer. Material of the second metal layer is a transparent material. By setting the material of the second metal trace as a transparent material, the metal trace provided by the second metal layer around the boundary between the display area and the electronic component installation area is transparent. Thus, the second metal trace does not impact transmission of the electronic component area, such that the electronic component area can normally transmit light.
In an embodiment, the liquid crystal display panel includes a display area including a source/drain layer, and material of the source/drain layer is a transparent material.
In an embodiment, the transparent material includes, but is not limited to, indium tin oxide. A metal disposed at a boundary around the display area and the electronic component is made of a transparent material, such as indium tin oxide, such that the electronic component area can normally transmit light and work normally.
In an embodiment, considering that the metal layer of the liquid crystal display panel is made of a transparent material, the metal layer can be disposed over the entire surface, that is, the metal trace can be disposed in the electronic component area, and the metal trace does not impact the transmittance of the electronic component area. By setting the metal trace in the electronic component area, a spacing between the metal traces can be increased without increasing the border of the liquid crystal display panel, thereby preventing metal traces from having too small pitch to result in short-circuit. In addition, a cross-sectional area of the metal traces can be increased, so that the metal traces have better performance. For example, the metal traces are not easy to be blown when current or voltage passes, and resistance of the metal traces is smaller, thus improving the display effect of the liquid crystal display panel, and reducing a probability of failure of the liquid crystal display panel.
In this embodiment of the present invention, the electronic component area is formed into the liquid crystals and the retaining walls, wherein the retaining walls are transparent and do not impact the display of the electronic component area, and for the electronic component area provided with liquid crystals, the transmittance of the electronic component area is increased.

In an embodiment, the electronic component includes a camera disposed in the corresponding electronic component area, and the liquid crystals and the retaining walls are formed by processing the polymer dispersed liquid crystals in the electronic component area, thereby eliminating the border between the display area and the electronic component area. Since the liquid crystals and the retaining walls are both transparent, and the area where the liquid crystals are provided has an improved transmittance compared with the electronic component area, so that the light received by the camera is clearer and more realistic, thus improving the image capturing effect of the camera.
In an embodiment, the electronic component includes an infrared sensor. Since the liquid crystals and the retaining walls disposed in the electronic component area improve the transmittance of the electronic component area, the infrared sensor disposed in the electronic component area can receive a more realistic image, thereby reacting more quickly and accurately.
In an embodiment, the electronic component is disposed between the backlight module and the liquid crystal display panel. In the electronic component area, the backlight module is not provided with a light source. Since the electronic component area is not configured to display, it is not necessary to set the light source in an area of the backlight module corresponding to the electronic component area, thus preventing the problem that the light source of the backlight module disposed in the corresponding electronic component area impacts operation of the electronic component.
In an embodiment, the electronic component is disposed between the backlight module and the liquid crystal display panel. In the electronic component area, the backlight module is provided with a light source, and a light shielding plate is arranged on a side of the electronic component close to the backlight module. In consideration of obtaining stronger light, light sources are disposed on an entire surface of the backlight module, and the light shielding plate is disposed on a side of the electronic component close to the backlight module, so that the light source does not impact normal operation of the electronic component.
In an embodiment, the light shielding plate may be disposed around the electronic component, but only not on a side of the electronic component close to the liquid crystal display panel, so that the electronic component area does not have light leakage, and the electronic component can be better protected from the impact of the light source.
In an embodiment, the electronic component is disposed in a direction of the backlight module away from the liquid crystal display panel. The electronic component can be normally operated by digging an opening in a backlight module, or by setting a region of the backlight module corresponding to the electronic component area to be transparent.
