A display apparatus includes an input/output interface connected to an external device and an input device, a memory, a first processor connected to the memory, and a second processor configured to be recognized as a universal serial bus (USB) device by the external device. The first processor generates a first image related to a function of the display apparatus, and a second image based on image data obtained from the external device, and controls the display to display the first image and the second image together. The first processor obtains an input signal from the input device, and based on a cursor corresponding to the input signal being located on the second image, provides the input signal to the second processor, and the second processor provides the input signal to the external device.

Display apparatus and controlling method thereof

An electronic device for receiving and displaying an application screen from an external device, includes: a display including a touch sensor; a communication interface; and at least one processor configured to: control the display to display a first application screen received from the external device through the communication interface and a writing pressure adjustment user interface (UI), transmit, to the external device, information on a writing pressure value set through the writing pressure adjustment UI and a touch input identified through the touch sensor, receive, from the external device through the communication interface, a second application screen including a touch trajectory identified based on the information on the writing pressure value and the touch input, and control the display to display the received second application screen.

Electronic device for receiving and displaying application screen from external device and method for controlling same

The display apparatus includes a display including a touch screen; a plurality of transducers provided to be spaced apart from each other at edges of the touch screen, and configured to transmit and receive an ultrasonic signal with respect to the touch screen; and a processor configured to identify a touch position on the touch screen based on the ultrasonic signal transmitted and received by the plurality of transducers, wherein the transducer includes a plurality of electrodes arranged from an edge side of the touch screen toward an inner side of the touch screen, and a first electrode at the edge side among the plurality of electrodes is shorter than a second electrode at the inner side.

Display apparatus and control method thereof

A display apparatus includes a display, a plurality of light emitting elements that emit light of different wavelengths and a plurality of light receiving elements, and a processor that identifies intensities light emitted by the light emitting elements and received by the light receiving elements to identify a pen color of a touch pen on a basis of the intensities.

A display apparatus is disclosed. The display apparatus includes a touch display, a camera, and a processor configured to control the camera to capture an image including the touch display, based on an object being identified from an image captured through the camera, obtain a first position of the object on the touch display based on the image, identify whether the first position is within a predetermined distance from a second position where the touch input is sensed based on a touch input of the object being sensed on the touch display, and based on the first position being within the predetermined distance from the second position, control the touch display to display a touch trajectory corresponding to the touch input based on the identified object.
