Touch screen and display apparatus

A touch screen, comprising an array substrate and a color filter substrate which are aligned and combined with each other, liquid crystal and a main photo spacer are provided between the array substrate and the color filter substrate, the touch screen further comprises a primary emitting module, a secondary emitting module and a processor, wherein,

• the primary emitting module comprises a first emitting electrode and a receiving electrode, the first emitting electrode and the receiving electrode are provided on a surface of the color filter substrate away from the array substrate, and a first capacitance is formed between the first emitting electrode and the receiving electrode, the first emitting electrode is configured to emit an excitation signal to the receiving electrode, the receiving electrode is configured to transmit the excitation signal to the processor;
• the secondary emitting module is provided between the color filter substrate and the array substrate, comprises a black matrix, and is configured to emit a secondary signal to the receiving electrode when a finger touches the touch screen and a touch pressure of the finger is greater than a predefined value, so that a characteristic of the excitation signal received by the receiving electrode changes;
• and
• the processor is configured to process the excitation signal to obtain the characteristic of the excitation signal and determine an intensity of the touch pressure of the finger in accordance with the characteristic of the excitation signal.
