Abstract: Provided is a photosensitive resin composition including a reactive unsaturated compound, an alkali soluble resin, an initiator, and a pigment. The reactive unsaturated compound is selected to cause the composition to exhibit high-resolution pattern properties that facilitate forming a pixel defining film in a display device. The reactive unsaturated compound may be an acryl-based compound having at least three ethylenically unsaturated double bond groups in molecules and having a viscosity of about 200 mPa s to about 280 mPa s at 40° C. A display device including such pixel defining film is also presented.

Abstract: A method for controlling an electric heater of a vehicular heating, ventilation, and air conditioning (HVAC) system includes turning on the electric heater; determining whether an ambient air temperature of a vehicle is higher than or equal to a threshold ambient air temperature, and a battery temperature is lower than or equal to a threshold battery temperature; determining whether battery efficiency is lower than or equal to threshold efficiency when the ambient air temperature of the vehicle is higher than or equal to the threshold ambient air temperature, and the battery temperature is lower than or equal to the threshold battery temperature; and turning off the electric heater when the battery efficiency is lower than or equal to the threshold efficiency, wherein the electric heater is configured to receive electric energy from the battery.

Abstract: An apparatus for controlling a rearview mirror angle of vehicles, includes an overcurrent sensing unit for generating a trip signal for driving a photo coupler when overcurrent is applied to a driving motor, a poly-switch being connected to one input terminal of the driving motor, and connected in parallel to a resistor; an initial driving and off maintaining unit for driving the driving motor when power is inputted to input terminals, and maintaining an off status of the driving motor when the trip signal is inputted from the overcurrent sensing unit; and a relay turned on/off according to driving of the initial driving and off maintaining unit, for interrupting forward/backward power supplied to the driving motor.
