A lithium ion battery control system includes a degradation rate calculating unit, a degradation rate storage unit, a degradation rate comparing unit, a charging and discharging control circuit, and a rechargeable battery. The degradation rate calculating unit calculates a degradation rate when receiving a trigger for starting the check of the degradation rate of the battery. The degradation rate comparing unit receives a present degradation rate from the degradation rate calculating unit and a previous degradation rate from the degradation rate storage unit and compares both degradation rates. As a result, when the present degradation rate is greater than the previous degradation rate by a predetermined value, a charging and discharging condition is limited.

摘要:
The present invention provides OLEDs of the top emission type comprising organic light-emitting (LE) elements by preventing the problems such as the widening of the power lines, the reduction in the aperture ratio caused by the widening of the upper and the lower capacitor electrodes and the short circuit between the upper and the lower electrodes caused by the roughness of the flattening layers. Two kinds of the OLEDs are provided. One is an OLED comprising a region of LE layer sandwiched between the upper and lower electrodes is formed on a power line of TFT for driving the pixel. Another comprises a region of the LE layer formed on an electrode of capacitor connected to the TFTs to control the light-emitting element. Accordingly, without forming a flattening layer on the light-emitting layer, there is no electric short circuit between the lower electrode and the upper electrode.

摘要:
A liquid crystal display unit in which a voltage is applied to a pixel electrode and a common signal electrode constituted by two upper and lower transparent conductive layers having insulation layers disposed therebetween so that a liquid crystal is driven to control display can improve any one or both of reduction of a writing time of the liquid crystal (reduction of a capacitance between the pixel electrode and the common signal electrode) and reduction of a driving voltage of the liquid crystal. An inter-layer insulation layer between the transparent electrodes formed of different layers is constituted by at least one or a laminated structure of a part of a gate insulation layer, a part of a surface protection layer of a thin film transistor and an applied-type insulation layer and insulation layers in an area which is positioned above the lower transparent electrode.
