Embodiment Construction

[0025] Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference symbols are used in the drawings and descriptions to refer to the same or like parts.

[0026] It will be understood that when a component such as a layer, film, region, or substrate is referred to as being “on” or “connected to” another component, it can be directly on or connected to the other component, or Intermediate components can also exist. In contrast, when a component is referred to as being "directly on" or "directly connected to" another component, there are no intervening components present. As used herein, "connected" may refer to physical and / or electrical connection. Furthermore, "electrically connected" or "coupled" may mean that other components exist between two components.

Abstract

The invention provides an electronic device with a fingerprint sensing function. The electronic device comprises a fingerprint sensing array, a plurality of fingerprint sensing signal reading lines, aplurality of touch control driving lines, a touch control driving circuit, and a reading circuit. The fingerprint sensing array comprises a plurality of fingerprint sensing units arranged in arrays.The fingerprint sensing signal reading lines are respectively coupled to one row of fingerprint sensing units of the fingerprint sensing array. The touch control driving lines and the fingerprint sensing signal reading lines are arranged in a staggered mode. The touch control driving circuit is coupled to a plurality of touch control driving lines and provides a plurality of touch control drivingsignals to the touch control driving lines. The reading circuit is coupled to the fingerprint sensing signal reading lines. Responding to a plurality of touch control driving signals outputted by thetouch control driving lines, the reading circuit decides the touch control position of a touch control object according to a plurality of reading signals outputted by a plurality of fingerprint sensing signal reading lines.

Description

technical field [0001] The present invention relates to a fingerprint sensing technology, and in particular to an electronic device with a fingerprint sensing function. Background technique [0002] With the development of touch technology and display technology, touch display devices have been favored by more and more users. Users can directly operate with fingers or stylus, and the operation mode is intuitive and very convenient. At present, touch display devices have been widely used in various types of electronic products, such as smart phones, tablet computers, or portable notebook computers. On the other hand, fingerprint identification technology is gradually widely used in various electronic devices or products, at least including capacitive, optical, ultrasonic and other fingerprint identification technologies are being continuously developed and improved. middle. [0003] However, as the touch screens of mobile electronic devices become larger and larger, the sp...
