An organic light-emitting diode display screen capable of detecting pressing force and a method of manufacturing the same

Abstract

The invention provides an organic light-emitting diode display screen capable of detecting pressing force and a method of manufacturing the same. The organic light-emitting diode display screen comprises an organic light-emitting diode display module, a capacitance type pressure sensing film and a support. At least one electrode is arranged on the capacitance type pressure sensing film. Filler with a thickness of D and a maximum compression ratio of R is arranged between the capacitance type pressure sensing film and the organic light-emitting diode display module, wherein D is greater than 0.1mm and R is not less than 50%. With the filler, the problem in the prior art that air in an air gap has no structure bearing capability is solved; with the high compression ratio of the filler, the flatness of two poles for a pressure detection capacitor is improved.

Description

technical field [0001] The invention relates to a display screen and a manufacturing method thereof, in particular to a display screen capable of detecting pressing force applied thereon and a manufacturing method thereof. Background technique [0002] In order to detect the pressing force applied on the display screen, there is a solution in the prior art, such as Figure 4 As shown, the display screen includes a display module 93 , a capacitive pressure sensing component 91 , and a bracket 92 . The capacitive pressure sensing component 91 is attached to the bracket 92, and an air gap 94 is formed between the display module 93 and the capacitive pressure sensing component 91. The capacitive pressure sensing component 91 includes at least one electrode, and the electrode is connected to the display module. The pressure detection capacitor C1 is formed between the groups 93 . When a pressing force is applied on the display screen, the display module 93 is deformed, and the d...

AI Technical Summary

Problems solved by technology

[0003] 1. The thickness of the air gap 94 is relatively large, and the air therein has no structural bearing capacity, and the devices on it are affected by gravity, so that the flatness of the top of the air gap 94 is poor;

[0004] 2. The uniformity of the distribution of the pressure detection capacitance C1 is affected by the flatness of the bracket 92. If the flatness of the bracket 92 is poor, the uniformity of the pressure detection capacitance distribution is poor, and the display screen is pressed to form a complicated data of the pressure detection capacitance change, which affects the data.
