    摘要: In described examples, a slew rate controlled gate driver circuit (400) generates a gate control signal (V
    G ) that rises substantially in step fashion until reaching a first threshold voltage level (V
    TH1 ), whereupon the gate control signal (V
    G ) rises at a controlled slew rate. When the gate control signal (V
    G ) rises beyond a second threshold voltage level (V
    TH2 ) that is greater than the first threshold voltage level (V
    TH1 ), the gate control signal (V
    G ) again rises substantially in step fashion.

    摘要: The device for LED direct driver comprises a major LED string, a minor LED string set, a pre-regulator, and a direct driver. The major LED string has multiple series-connected LED diodes which has a first end and a second end. The minor LED string set has a first end and a second end, and is formed with multiple series-connected minor strings. The first end of the minor LED string set is connected to the second of the major LED string. Each minor LED string has at least one LED diode. The direct driver is connected to the pre-regulator, the major LED string, the minor LED string, which is configured to short out selected minor LED strings for ensuring the most efficient LED driving configuration. The pre-regulator provides an regulated voltage output. The regulated voltage output fed to the LED direct driver that is able to allow the LED direct driver to provide a constant power output with virtually no output power ripple.

A first reference voltage driver (3) time-divisionally switches the first reference voltage lines (S2, S5). A first drive voltage driver (6) supplies first luminous drive voltages (B1, B2, ···; E1, E2, ···) to the first drive voltage lines (Y1, Y2, ···). One of the light-emitting elements (P 1,1, P 1,2, ···, P 3,1 ,P 3,2 ,···; P 4,1, P 4,2, ···) is located at each intersection between at least one second reference voltage line (S1, S3; S4) and "m" second drive voltage lines (X1, X2, ···; Z1, Z2, ···). A second reference voltage driver (2, 4) switches the second reference voltage line (S1, S3; S4). A second drive voltage driver (5, 7) supplies second luminous drive voltages (A1, A2, ···, C1, C2, ···; D1, D2, ···) to the second drive voltage lines (X1, X2, ···; Z1, Z2, ···).
