Description
Technical Field
The invention relates to the technical field of display, in particular to a display switch device.
Background
The simplest switch has two pieces of metal called contacts, which make the current form a loop when they are in contact and open when they are not in contact. The contact metal is selected with regard to its degree of corrosion resistance, since most metals oxidize to form insulating oxides that prevent the contact from functioning properly. The contact metal is selected in consideration of its conductivity, hardness, mechanical strength, cost and toxicity. Corrosion resistant metals are sometimes plated on the contacts. The contact surface is typically plated to avoid oxide degradation of the contact. Non-metallic conductive materials, such as conductive plastics, are sometimes used for the contact surfaces.
With the spread of liquid crystal displays, push-button switches with narrow-bezel display devices are becoming more popular because they can display information such as numbers, letters, and patterns on the push-button switches. The liquid crystal panel is a material for determining the brightness, contrast, color and visual angle of the liquid crystal display, and the quality of the liquid crystal panel directly affects the user experience. The AMOLED display panel is paid more attention to by people in the market, the AMOLED is an active matrix organic light emitting diode panel, and the AMOLED display panel has the characteristics of high response speed, high contrast and wide viewing angle. The light emitting device of the AMOLED is an organic light emitting diode OLED, and when current flows through the organic light emitting diode OLED under the driving of the AMOLED scanning circuit, the organic light emitting diode OLED emits light. However, the scanning circuits on the AMOLED are all disposed on the front side of the display screen and located on the left and right sides of the front side of the display screen, which occupies space and affects the large-screen high-definition design of the display screen structure in the later period. In the prior art, the optical elements for outputting images are all display panels, images are all presented through the display panels, the optical fiber panels are not used as the optical elements for outputting images, and the optical fiber panels in the prior art are only used for fingerprint conduction. Due to the fact that the array structure design of the scanning circuit leads to the fact that the frame of the screen body of the display screen is wide, the requirement of a user for the narrow frame of the display screen is higher and higher, and the scanning circuit is more favored to be used for the narrow frame and even is not used for the frame. At present, due to the limitation of a manufacturing process, a frame for fixing a display screen cannot realize display, so that full-screen display on the front surface of electronic equipment cannot be realized. Therefore, the borderless display is especially necessary, especially for the application of the button switch.

The borderless display device disclosed in this patent document is capable of displaying a display medium on the entire surface of the button. However, the lens magnifies the display image light, especially the display image edge light, which causes the display image edge to be distorted, and the peripheral edge part of the lens is easy to generate glare, which affects the overall display effect.
