An OLED display for producing a full color image, comprising a plurality of at least four different colored pixels including three different colored addressable gamut-defining pixels and a fourth addressable within-gamut pixel, each pixel having an organic light-emitting diode with first and second electrodes and one or more organic light-emitting layers provided between the electrodes; the OLED display having a selected display white point, display peak luminance, gamut-defining pixel peak luminances and within-gamut pixel peak luminance; and drive circuitry for regulating luminance of the organic light-emitting diode of each of the colored pixels wherein the sum of the gamut-defining pixel peak luminances is less than the display peak luminance.

The invention relates to an intelligent multi-loop electric automobile cooling system. The intelligent multi-loop electric automobile cooling system comprises a power battery pack, an armature module, a battery radiator, an armature radiator, electric water pumps, straightway valves, three-way valves, a PTC heater and a heat exchanger. The cooling system is provided with the two electric water pumps, the two straightway valves and the three three-way valves, and a plurality of loops are formed through pipeline connection. Compared with the prior art, the intelligent multi-loop electric automobile cooling system is provided with the multiple three-way valves and the straightway valves, pipelines are connected to form the loops meeting different cooling or heating needs, the loops are selectively opened or closed according to the characteristics and working states of the electric automobile power battery pack and the armature module, thus temperature balance of an electric automobile is ensured, efficient operation of the electric automobile is ensured, and system energy conservation is significant. Power battery pack cooling and armature module cooling are associated with each other, thus automobile endurance mileage becomes longer, and the power performance and economy of the automobile become better.

In some embodiments, a method and apparatus for power performance monitors for low-power program tuning are described. In one embodiment, the method includes the computation of power consumption levels of instructions of an application. Once consumption levels are computed, instruction sequences of the application are identified that exhibit an excess power consumption level. For the identified instruction sequences, the application program is recompiled to reduce power consumption levels of one or more of the identified instruction sequences. Other embodiments are described and claimed.

A low power charge pump is disclosed. A pump driving node of a first pump stage is selectively coupled to a pump driving node of the subsequent pump stage. Subsequent to a transfer of charge from a first pump stage to a subsequent stage, the first and subsequent pump driving nodes are coupled. Residual charge on a first stage pump driving node is thereby transferred to a subsequent pump driving node. Subsequent to the transfer of charge from the first pump driving node to the second pump driving node, the nodes are uncoupled. By selectively coupling a first pump stage to a pump driving node of the subsequent pump stage, the first pump driving node may pre-charge the subsequent pump driving node, thereby reducing the energy that must be provided by clock driving circuitry to produce a positive-going transition of a driving clock. Advantageously, pre-charging energy is taken from the first stage, reducing the energy that was heretofore dissipated by clock driving circuitry during a negative-going clock signal transition. In this novel manner conversion efficiency of a charge pump device may be beneficially increased, providing enhanced low power performance.
