A touch scanning method is used for a TPIC chip and includes: receiving a emission synchronization signal sent by a DDIC chip, the light emission synchronization signal being synchronized with an EM signal controlled by the DDIC chip; and by taking the emission synchronization signal as a synchronization reference, performing continuous touch scanning according to a touch scanning frequency, where a time point of the touch scanning is aligned with a time point at which the emission synchronization signal is received. The emission synchronization signal sent by the DDIC chip is synchronized with the EM signal, and the EM signal is stable, therefore upon the receipt of the emission synchronization signal, the TPIC chip can perform continuous touch scanning with the emission synchronization signal as the synchronization reference according to a stable touch scanning frequency, thereby facilitating the improvement of the identification rate and accuracy for a touch operation.

Touch scanning method and display module

A display screen frequency conversion method and a terminal (). The method is applied to a DDIC chip of an OLED display screen, including: initializing display screen parameters according to a first refresh rate; in response to receiving first image data sent by an AP, performing an image scanning according to the first refresh rate; in response to not receiving second image data sent by the AP within a preset delay duration of a VFP corresponding to the first refresh rate, adjusting the first refresh rate to a second refresh rate; wherein the second refresh rate is less than the first refresh rate; and adjusting the display screen parameters according to the second refresh rate.

Display screen rate conversion method and terminal

Disclosed are an information display method, a terminal device, and a readable storage medium. The information display method includes: obtaining an information type of each of a plurality of to-be-displayed information; in response to the information type comprising a target information type, obtaining a first refresh frequency of a target to-be-displayed information corresponding to the target information type, and determining a first display frequency of a display screen according to the first refresh frequency; and displaying the plurality of to-be-displayed information according to the first display frequency.

Information display method, terminal device, and storage medium

The present disclosure relates to a sound production device, a display device, and a terminal. The sound production device includes a first electrode layer arranged on a display substrate; an insulating layer arranged on a side of the first electrode layer away from the display substrate; an electromagnetic coil arranged on a side of the insulating layer away from the first electrode layer; a magnetic diaphragm arranged on a side of the electromagnetic coil away from the insulating layer and configured to vibrate and produce sounds in response to a magnetic field generated by the electromagnetic coil, wherein a vertical projection of the electromagnetic coil on the display substrate and a vertical projection of the magnetic diaphragm on the display substrate falls on a non-opening area, the insulating layer defines a via, and the electromagnetic coil and the first electrode layer are electrically connected through the via.
