Description
Technical Field
The invention relates to the technical field of display, in particular to a frameless 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.
In recent years, with the spread of liquid crystal displays, push-button switches with narrow-bezel display devices have been increasingly favored 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 experience of a user. The AMOLED display panel which is paid more attention by people in the market is an active matrix organic light emitting diode panel, and has the characteristics of high reaction 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 disposed on the front side of the display screen and 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, all optical elements for image output are display panels, images are presented through the display panels, the optical fiber panels are not used as optical elements for image output, and the optical fiber panels in the prior art are only used for fingerprint conduction.
