Problems solved by technology

[0004] However, since the pressure touch unit is formed on the backlight side of the display panel, the user needs to apply a large force to simultaneously press the touch panel and the display panel until deformation occurs, so that the pressure touch unit can detect the change in capacitance , so it is difficult for the pressure touch unit to detect a small force, and the display screen is not sensitive enough to detect the pressure

Abstract

The invention discloses a display screen, comprising a display panel, a pressure detection layer, an insulating layer, a pressure sensing layer and a touch panel, wherein the display panel comprises a display material layer; the pressure detection layer is formed on the exit side of the display material layer; the insulating layer is formed on one side, away from the display material layer, of the pressure detection layer; the pressure sensing layer is formed on one side, away from the pressure detection layer, of the insulating layer, the pressure detection layer, the insulating layer and the pressure sensing layer jointly form a detection capacitor, and the detection capacitor is used for being connected with a pressure control chip; and the touch panel is formed on one side, away from the insulating layer, of the pressure sensing layer. The pressure detection sensitivity of the display screen is high. The invention further discloses a display.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display screen and a display. Background technique [0002] The traditional liquid crystal display (Liquid Crystal Display, LCD) display screen only provides the display function. If the pressure touch function is to be added, an external touch panel (TouchPanel, TP) is generally added to the light-emitting surface of the display panel of the display screen. At the same time, an external pressure touch unit is added to the backlight side of the display panel. [0003] The pressure touch unit generally needs to include a pressure (force) detection layer and a pressure (force) sensing layer that are insulated from each other and are very close to each other. The pressure detection layer, the pressure sensing layer and the insulating layer (such as an air layer) between A sensing capacitor is formed, so the pressure touch unit is actually a capacitive sensing unit. Exis...
