According to the embodiment of the application, the structural relationship between the driving layer 100 and the color layer 200 is fully utilized, the spatial positions of the driving layer 100 and the color layer 200 relative to the electronic equipment are changed, the driving layer 100 and the color layer 200 are reversely arranged, the driving layer 100 is arranged on the outermost side of a display panel of the electronic equipment, the color layer 200 is arranged on one side of the driving layer 100 facing the inside of the electronic equipment, after the driving layer is arranged, the glass substrate 120 of the driving layer 100 is constructed into a display screen of the display device, the liquid crystal driving circuit 100 is arranged on one side of the driving layer facing the inside of the electronic equipment, and the electric control element 130 connected with the liquid crystal driving circuit 110 is arranged in a region defined by the application, so that the elements including the electric control element 130, which possibly affect the appearance, the screen expansion structure, the full screen structure, the light and thin structure of the display screen, are prevented from being exposed to the outside visual field of the electronic equipment, and the unnecessary shielding structures are prevented from being added for the elements.
In practical applications, the driving layer 100 may be implemented by a related functional structural layer including TFT (Thin Film Transistor) glass, but not limited to TFT, and the driving layer 100 is also briefly described by a TFT glass example, where a display panel of a display device includes a plurality of pixels at the same time, and the TFT glass provides a driving voltage through a transistor to provide driving for each pixel, so as to present corresponding display content; the color layer 200 may now be implemented by a related functional structural layer including CF (Color filter) glass, but not limited to CF, and this is also exemplified by CF glass, and the color layer 200 causes the content to be displayed to be presented in color by providing respective colors for the respective pixels. For example, for an exemplary liquid crystal display panel, liquid crystal 700 is encapsulated between TFT glass and CF glass, and a transistor disposed on the TFT glass forms the liquid crystal driving circuit 110, which can provide driving voltage to drive liquid crystal 700 molecules, thereby realizing pixel driving; an electric control element 130 connected to the liquid crystal driving circuit 110 for supplying power to the liquid crystal driving circuit 110 so that the transistors constituting the liquid crystal driving circuit 110 form a corresponding electric field; that is, the liquid crystal driving circuit 110 and the electronic control element 130 are located at one side of the driving layer 100 facing the color layer 200, so that the driving layer 100 is disposed at a position facing the external space of the electronic device directly, and when the color layer 200 is located at one side of the driving layer 100 facing the internal space of the electronic device, the glass substrate 120 of the driving layer 100 forms a display screen of the display device, and the liquid crystal driving circuit 110 and the connected electronic control element 130 are located at the back of the display screen, thereby avoiding that when the color layer 200 forms the display screen of the electronic device, additional components are required to be added to shield the electronic control element 130, solving the problem that the screen ratio of the display screen is low, and the glass substrate 120 of the driving layer 100 is not affected by the electronic control element 130 and can be expanded according to design requirements, so as to improve the screen ratio of the display screen of the electronic device and achieve the purpose of full screen.
In particular, as shown in fig. 4 and 5, the electronic control assembly may include an electrical connection portion 140 and a connector 150, where the connector 150 is disposed on the driving layer 110, for example, on the glass substrate 120 and is electrically connected to the liquid crystal driving circuit 110, and the electrical connection portion 140 communicates the liquid crystal driving circuit 110 and the electronic control element 130 through the connector, so that the electronic control element 130 can provide a corresponding driving voltage for the liquid crystal driving circuit 110, so that a corresponding pixel can exhibit a corresponding display state; the electrical connection portion 140 is disposed in a space opposite to the first surface of the driving layer 100, so that the glass substrate 120 of the driving layer 100 can directly cover the electrical connection portion 140, and no additional component is required to be used for shielding on the display screen, thereby improving the screen ratio of the display screen of the electronic device.

In specific implementation, the electronic device is a notebook computer with a rotation shaft 800; at this time, the electronic control element 130 may be disposed inside the rotating shaft 800, or may avoid occupying a frame portion of the display screen, so as to improve the screen ratio of the display screen.
In general, in order to realize a pixel driving circuit, the driving layer 100 is formed by a multi-layer structure, as shown in fig. 6, when the driving layer 100 is powered off, external incident light irradiates the driving layer 100 (especially when the light is strong), directions of the incident light and the emergent light are shown by arrows pointing on the incident light and the emergent light in the figure, when the light passes through the glass substrate 120 and each layer structure of the driving layer, the emergent light is not directly reflected out as a light reflection route on the left side of fig. 6, but is reflected out as an emergent light on the right side of fig. 6, a rainbow-like color block is generated due to a difference between the interlayer distances of the driving layer, so that an optical color difference problem is caused, and a display abnormality occurs when a user sees a display screen under the condition that the display device is powered off.
