Problems solved by technology
[0002] For a general image sensor, since some circuit nodes in the circuit of the sensing pixel may float when the plurality of transistors of the sensing pixel of the image sensor (for example, 3T structure) are switched between different operation modes, so that some circuit nodes voltage becomes unstable and susceptible to transistor leakage currents or capacitive coupling effects
Therefore, general image sensors usually have the problem of output loss

Embodiment Construction
[0062] Throughout the specification of the present disclosure and the appended claims, specific terms are used to refer to specified components. It will be understood by those of ordinary skill in the art that display device manufacturers may refer to the same components by different names. In the description, it is not intended to distinguish components having the same function but different names. In the following specification and claims, the words "comprising" and "comprising" are open-ended words and should therefore be interpreted as "including, but not limited to...".
[0063] In some embodiments of the present disclosure, with respect to words such as "coupled," "interconnected," and the like. With reference to joining and connecting, unless explicitly defined, these terms mean that two structures are in direct contact or that two structures are not in direct contact, and that other structures are provided to be disposed between the two structures. The words about me...

The invention provides an electronic device and a control method. The electronic device includes a sensing pixel. The sensing pixel comprises a photosensitive unit, a first transistor, a second transistor and a third transistor. The first transistor is coupled to the photosensitive unit and is used for receiving a reset signal. The second transistor is coupled to the photosensitive unit. The third transistor is coupled to the second transistor and is used for receiving the scanning signal. During the reset period, a reset signal waveform of the reset signal and a first scan signal waveform of the scan signal at least partially overlap. According to the electronic device and the control method, the output loss of the sensing pixels of the electronic device can be improved.
Description
technical field [0001] The present disclosure relates to a device, and more particularly, to an electronic device and a control method thereof. Background technique [0002] For a general image sensor, since some circuit nodes in the circuit of the sensing pixel may be floating when multiple transistors of the sensing pixel of the image sensor (eg, 3T structure) are switched between different operation modes, some circuit nodes may be floating The voltage becomes unstable and susceptible to transistor leakage current or capacitive coupling effects. Therefore, general image sensors usually have the problem of output loss. In view of this, several embodiments are presented below. SUMMARY OF THE INVENTION [0003] Electronic devices of the present disclosure include sensing pixels. The sensing pixel includes a photosensitive unit, a first transistor, a second transistor and a third transistor. The first transistor is coupled to the photosensitive unit and used for receivi...
