Camera optical lens

A camera optical lens includes six-piece lenses, from an object side to an image side, the six-piece lenses are: a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a negative refractive power, a fourth lens, a fifth lens having a positive refractive power and a sixth lens having a negative refractive power. The camera optical lens satisfies conditions of 0.65≤f1/f≤0.85, 0.80≤d3/d4≤1.20, 0.85≤d8/d9≤1.35, and −4.00≤R9/R10≤−2.00. Here f denotes a focal length of the camera optical lens, f1 denotes a focal length of the first lens, d3 denotes an on-axis thickness of the second lens. The camera optical lens of the present disclosure has excellent optical performances, and meanwhile can meet design requirements of ultra-thin and a wide angle.

A camera optical lens includes five-piece lenses, from an object side to an image side, the five-piece lenses are: a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens, a fourth lens having a negative refractive power and a fifth lens having a positive refractive power. The camera optical lens satisfies conditions of 0.60&#x2264;f1/f&#x2264;0.90, 1.80&#x2264;d6/d8&#x2264;3.20, 0.55&#x2264;f2/f4&#x2264;1.00, and 5.50&#x2264;f5/f&#x2264;10.00. Here f denotes a focal length of the camera optical lens, d6 denotes an on-axis distance from an image-side surface of the third lens to an object-side surface of the fourth lens, and d8 denotes an on-axis distance from an image-side surface of the fourth lens to an object-side surface of the fifth lens. The camera optical lens of the present disclosure has excellent optical performances, and meanwhile can meet design requirements of a large aperture, a wide angle and ultra-thin.

A display driving circuit includes a light emitting assembly which includes a first control switch having a first terminal connected to a cathode of the light emitting unit, a second terminal connected to a common terminal, and a control terminal connected to a first signal wire to provide a first control signal and a second control switch having a first terminal connected to a charging terminal, a second terminal connected to an anode of the light emitting unit and a control terminal connected to a second signal wire to provide a second control signal. When the light emitting unit is turned off, the first control switch disconnects the cathode of the light emitting unit and the common terminal in response to the first control signal, and the second control switch disconnects the anode of the light emitting unit and the charging terminal in response to the second control signal.
