  • Publication number: 20150074578
    Abstract: In embodiments of text select and enter, selectable character strings (124) can be determined from text (118) that is displayed in display interfaces on a display device. A character string mapping table (122) can then be generated that identifies a selection position (126) of each selectable character string that is displayed. A selection of a selectable character string can be received, and the chosen selectable character string determined from the string mapping table based on a selection position on a touch-sensitive display component (106). The chosen selectable character string can then be duplicated as a text entry at a cursor position in a text edit field (120) responsive to the selection of the selectable character string and without additional user input.

  • Publication number: 20140346954
    Abstract: The present invention discloses a white LED light emitting device driven directly by constant current in manner of being supplied with alternating current. N parallel branches, consisting of LED modules and constant current units which are in series connection with the LED modules, are connected to an output terminal of a rectification circuit, and by setting the current value, the turning-off voltage, and the turning-on voltage of the constant current unit of each branch, the periodic flickers generated due to changes in the voltage of the alternating current can be avoided. Because the current of each branch is constant, the changes in junction temperatures do not result in the current changing in LED, and the reliability is improved. Along with the increase of the number of the branches, the driving current waveform approximates a sine wave, and the power factor and the efficiency of the light emitting device are improved.

  • Patent number: 8883525
    Abstract: A white LED lighting device driven by a pulse current is provided, which consists of blue, violet or ultraviolet LED chips, blue afterglow luminescence materials A and yellow luminescence materials B. Wherein the weight ratio of the blue afterglow luminescence materials A to the yellow luminescence materials B is 10-70 wt %:30-90 wt %. The white LED lighting device drives the LED chips with a pulse current having a frequency of not less than 50 Hz. Because of using the afterglow luminescence materials, the light can be sustained when an excitation light source disappears, thereby eliminating the influence of LED light output fluctuation caused by current variation on the illumination. At the same time, the pulse current can keep the LED chips being at an intermittent work state, so as to overcome the problem of chip heating.
