Problems solved by technology
According to the design idea of the electromagnetic film in the related technology, a channel is composed of a single antenna, and the resistance value of each channel will reach thousands of ohms, so that the electromagnetic signal will be very weak, and the external chip cannot detect the electromagnetic signal, resulting in a shock. Control function failure

The invention relates to a display panel and terminal equipment, the display panel comprises a pixel unit array and a touch control electromagnetic antenna group, and the touch control electromagnetic antenna group comprises a plurality of first electromagnetic antenna groups arranged along a first direction and a plurality of second electromagnetic antenna groups arranged along a second direction; each first electromagnetic antenna group comprises at least two first electromagnetic induction antennas, and the at least two first electromagnetic induction antennas in the first electromagnetic antenna group are electrically connected in the non-display area; each second electromagnetic antenna group comprises at least two second electromagnetic induction antennas, and the at least two second electromagnetic induction antennas in the second electromagnetic antenna group are electrically connected in the non-display area. The at least two first electromagnetic induction antennas and the at least two second electromagnetic induction antennas can be connected in parallel in the non-display area, the resistance value of an antenna channel is further reduced, the parallel connection effect of the antennas is improved, the intensity of electromagnetic signals is enhanced, and therefore the probability of touch failure is reduced, and meanwhile the aperture opening ratio of the display panel is improved.
Description
technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a terminal device. Background technique [0002] The touch screen industry has successively undergone different types of development such as acoustic wave, infrared, resistive, capacitive, electromagnetic induction, etc., and has now formed a relatively mature industry posture. Among them, the electromagnetic induction touch technology has many advantages such as accurate positioning, sensitivity, original pen display, no fear of scratches, good positioning uniformity, no fear of accidental touch, and strong anti-interference ability of the antenna. [0003] In the related art, the electromagnetic induction touch technology uses an electromagnetic pen to transmit electromagnetic signals, and then interacts with the electromagnetic induction board behind the display screen. When the electromagnetic pen is close to the touch screen, the electrom...
