Description

Frameless display switch

Technical Field

The utility model relates to show technical field, especially relate to a no frame display switch.

Background

The simplest switch has two pieces of metal called "contacts" that 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 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.

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.

Chinese patent publication No. CN 104779107a, published as 2015, 07/15, discloses a borderless display device, which includes a button including a lens and a button cover, wherein the display device is disposed below the lens, the lens is disposed on an upper surface of the button, a curved surface is formed on an outer periphery of the upper surface of the lens, a concave portion is formed below the lens, a step portion is formed on the outer periphery of the lens, and an inclined surface facing a center of the lens is formed on the step portion, thereby eliminating a border on the upper surface of the button and displaying a display medium on an entire surface of the button.

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 light rays of the display screen, which is expressed by small visual angle and dispersion of the screen, and the peripheral edge of the lens is easy to generate glare, which affects the overall display effect.
